A family on Belgrave Square called us in September. They had inherited a Grade II-listed Georgian townhouse with five floors, ten principal rooms, a lower-ground-floor kitchen, and a garden at the rear. The property had not been significantly renovated since the 1960s. Original features throughout cornicing, ceiling roses, original shutters, original fireplaces on every principal floor, and the original kitchen range in the lower ground floor kitchen.
But sixty years of deferred maintenance had taken their toll. Roof failing. Electrical installation requiring full replacement. The heating system is a hybrid of 1970s oil-fired and gas, inefficient and, in some areas, unsafe. Lime plaster is failing on three principal floors, the result of gypsum plaster repairs applied to a lime substrate during the 1980s. The lower-ground-floor kitchen is structurally uncertain and spatially inefficient, the result of a 1960s flat conversion that was never properly resolved.
The family had obtained four renovation programmes from four separate companies. The programmes ranged from eighteen months to three years.
None of them explained why the time range was so wide. None of them was fixed price. None of them covered all trades.
We proposed an eighteen-week programme. One company. All trades in-house. One fixed price. One project manager. The family moved back into the property at week nineteen.
The best of the four original programmes would have taken them to week seventy-eight.

The Belgrave Square family’s four renovation programmes ranged from eighteen months to three years. The actual building work, roof repair, full rewire, new heating, lime plaster repair on five floors, three bathroom renovations, kitchen renovation, decoration, and flooring, was the same in every programme. The building did not become more complex or more straightforward depending on which company was being asked to renovate it. The work was the work.
The reason the programmes differed so dramatically, eighteen months versus three years for the same scope of work, was not the work itself. It was the gaps between stages that each programme model would produce.
In the four-company model, the main contractor coordinates separate roofing, electrical, plumbing, and specialist subcontractors. The gaps between stages are structural. The main contractor cannot begin the lime plaster repair until the electrical first fix is complete. The electrical first fix contractor becomes available in six weeks. The main contractor cannot begin the kitchen installation until the structural work is complete. The structural work requires Listed Building Consent, which will take eight weeks to obtain. The structural contractor cannot begin until the lime plaster team has finished. The lime plaster team finishes on a Friday, and the structural contractor’s next available start date is the following month.
These gaps are not exceptional. They are the normal output of a renovation programme managed across multiple separate companies with separate programmes, separate teams, and separate availability windows. In London renovation, they are so common that they are expected to be built into the most optimistic programme estimates as contingency and into the most pessimistic as certainty.
In a five-floor Georgian townhouse in Belgravia, the cumulative effect of these gaps across every stage transition is a programme that stretches from eighteen months at best to three years in the case where the gaps compound.
At Belgravia, rented accommodation costs of £12,000 to £20,000 per month for a property of equivalent size, the Belgrave Square family were looking at accommodation costs of £216,000 to £360,000 at eighteen months and £432,000 to £720,000 at three years.
None of the four companies had mentioned this cost. None of their programmes had explained why the time range was so wide. And none of them had offered a fixed price, because a programme managed across separate companies cannot be fixed-priced. The gaps cannot be predicted and therefore cannot be guaranteed.
The Belgrave Square Georgian townhouse renovation had twelve distinct programme stages: roof repair, Listed Building Consent application, NICEIC rewire, Gas Safe heating replacement, structural work on consent receipt, lime plaster repair on five floors, three bathroom renovations, kitchen renovation, flooring on five floors, decoration on five floors, second fix throughout, and handover.
Every one of these twelve stages had a dependency. The roof had to be weathertight before internal plastering could begin because water ingress during plastering would contaminate the new lime render and require the affected areas to be redone. The electrical first fix had to be complete before lime plaster could close the walls, because chasing lime plaster for cable routes after it has been applied damages the finished surface and requires repair. The structural work could not begin until Listed Building Consent was received, a fixed legal requirement that cannot be accelerated by any amount of commercial pressure on the main contractor.
When all twelve stages and their dependencies are managed by one company with all trades employed directly, with one project manager coordinating every stage, and with the programme built to eliminate gaps rather than accommodate them, the dependencies become a sequencing advantage rather than a coordination problem.
Stage one completes on Friday. Stage two begins on Monday. Not because the contractor has been pressured to be available. Because the same project manager who finished stage one starts stage two with the same team, on the same site, under the same programme.
This is the structural advantage of one company with all trades in-house over any multi-company programme model. Not a superior skill. Not lower prices. The elimination of the gaps between stages that in a Belgravia five-floor renovation represen
The Belgrave Square renovation programme was planned at the site visit stage before the fixed price was issued, before any work was contracted, and before the family had committed to anything. The programme plan showed every stage, every dependency, and every critical path relationship across the eighteen weeks.
Weeks one and two: roof repair. Three areas of active water ingress were confirmed at the site visit. Welsh slate replacement on the affected roof slopes. Lead valley and parapet flashing replacement. Guttering replacement on the north-facing elevation, where failure was contributing to the water ingress pattern. Our roofing team is on site from day one, no roofing subcontractor to coordinate, no waiting for availability.
Week three: Listed Building Consent application submitted. The application covers structural opening formation between the lower ground floor kitchen and breakfast room, and a chimney breast opening on the first floor drawing room, which the family wanted for an open fireplace reinstatement. The programme continues with non-consent-dependent stages during the determination period, the rewire and heating replacement proceed during the consent determination rather than waiting for consent to be granted before starting.
Weeks three and four: NICEIC full rewire. New consumer unit. New circuits throughout all five floors. All cable routing within existing wall chases, where possible, where new chases were required in lime plaster fabric, our electricians used oscillating tools rather than angle grinders to minimise the width of the chase and the damage to the surrounding plaster. First fix certificate issued at the end of week four.
Weeks four and five: Gas Safe heating replacement. New condensing gas boiler correctly sized for the property by our Gas Safe engineers using heat loss calculation rather than the rule of thumb. New pipework throughout all five floors. All existing pipework, the hybrid of 1970s oil-fired and gas, was removed rather than retained where it conflicted with the new system. All radiators were replaced on every floor. The heating system was commissioned and tested at the end of week five.
Weeks six through ten, lime plaster repair throughout all five principal floors. The 1980s gypsum repairs on three floors were carefully removed to expose the original lime substrate. Lime plaster damage in all affected areas was repaired in a three-coat hydraulic lime system: scratch coat, float coat, and finish coat, with adequate drying time between coats managed within the programme. Listed Building Consent received at week eight, structural work commenced immediately on receipt.
Weeks eight through ten: structural work. Opening formation between the lower ground floor kitchen and breakfast room. Steel lintel installation at both positions to the structural engineer’s specification. Chimney breast opening on first floor drawing room structural assessment confirmed the breast could be partially opened to create a working fireplace recess without compromising the structural integrity of the chimney above. Building Regulations inspection passed at the end of week ten.
Weeks ten through fourteen: bathroom renovation on three floors. Three bathrooms were renovated: the family’s principal bathroom on the first floor, the family bathroom on the second floor, and the en suite on the third floor. Each renovation follows our standard Belgravia bathroom process, listing condition assessment, lime plaster repair where applicable, Gas Safe plumbing, NICEIC electrics, waterproofing, tiling, and sanitaryware installation. Kitchen renovation on the lower ground floor, original kitchen range retained and restored, flagstone floor cleaned and repointed, new kitchen installed around the original features, Listed Building Consent conditions observed throughout.
Weeks fifteen and sixteen: decoration throughout all five floors. All surfaces prepared. All woodwork repaired and painted. All walls were decorated in the colours the family had selected during the renovation programme rather than at the end of it, because a programme managed by one company can integrate the decoration specification process while the building work proceeds, rather than beginning it when the building work is complete.
Weeks seventeen and eighteen: flooring on all five floors. Engineered wood in the principal rooms. Wool carpet in the bedrooms. Natural seagrass on the staircases. Second fix throughout. All appliances commissioned. All systems tested. Final snagging and handover preparation.
One fixed price for all eighteen stages. Confirmed at site visit. Honoured at the handover.
The Belgrave Square family occupied the property for the first time at the start of week nineteen. Eighteen weeks from the start of roof repair to handover.
The property they moved back into was not a renovated version of the house they had inherited. It was a restored version of what it had always been, the original features of the Cubitt-built Georgian townhouse visible throughout, the original kitchen range the centrepiece of the lower ground floor kitchen, the original cornicing and ceiling roses on the principal floors repaired and painted, the original shutters restored and operational, the original fireplaces on every floor cleaned and in working order. And a new roof. A new electrical installation with full NICEIC certification. A new heating system with a Gas Safe completion notice. Three new bathrooms with Gas Safe and NICEIC certificates. A new kitchen around the original listed features. New flooring on every floor. New decoration throughout.
The best of the four original programmes would have brought them back to a house in this condition at week seventy-eight. The accommodation cost of the difference of sixty weeks at £16,000 per month in equivalent Belgravia rented accommodation was £960,000.
The fixed price of the renovation was less than the accommodation savings.
Complete house renovation across Belgravia SW1, every stage from roof assessment through to final handover, all trades in-house, one project manager, one fixed price. Our complete house renovation Belgravia service covers roofing, structural work, Gas Safe plumbing, NICEIC electrics, lime plaster repair, original feature restoration, bathroom renovation, kitchen renovation, flooring, and decoration as a single programme with no gaps between stages and no programme gap accommodation costs for the family displaced from their property.
Our complete house renovation Belgravia service begins with a site visit that covers every element of the property, including roof condition, electrical installation, heating system, structural condition, listing conditions, original features, and programme planning. The fixed price is issued within 72 hours of the site visit and covers every stage of the renovation, including Listed Building Consent management where required.
Listed building house renovation in Belgravia, Grade I, Grade II*, and Grade II listed properties across the principal streets and squares of SW1. Every listed building house renovation in Belgravia begins with a listing condition assessment, reading the specific listing description for the building before making any programme or specification recommendation. This assessment determines what is present, what is listed, what requires Listed Building Consent, and what the renovation can proceed with on standard Building Regulations alone.
Listed building house renovation in Belgravia is the most complex residential renovation programme in our service area because the listing conditions of Belgravia’s Georgian townhouses are more extensive and more specific than those of most residential listed buildings in London, and because the original fabric of these buildings lime plaster, flagstone floors, kitchen ranges, original joinery, cornicing and ceiling roses requires specific knowledge and specific techniques that standard renovation companies do not have.
Georgian townhouse renovation in Belgravia, the complete renovation of a Cubitt-built Georgian townhouse across all floors, from the roof to the lower ground floor kitchen. Georgian townhouses in Belgravia are typically five to six floors, including the lower ground floor. A significant renovation programme that requires the full range of trades coordinated across multiple floor levels over a programme of twelve to twenty weeks, depending on the scope.
The defining characteristics of a Georgian townhouse renovation in Belgravia, lime plaster on lath throughout, original joinery and features on every floor, listed conditions covering the complete building fabric, and the programme management challenge of five or six dependent renovation stages across five or six floor levels are the characteristics that our all-trades-in-house approach is specifically designed to address.
Grade I listed house renovation in Belgravia is the highest category of listed protection, covering buildings of exceptional architectural and historic interest. Grade I listed buildings in Belgravia include some of the finest examples of Regency and early Victorian domestic architecture in the country — buildings where every element of the original fabric is specifically protected and where Listed Building Consent is required for almost any intervention that affects original features.
Grade I listed house renovation in Belgravia requires pre-application consultation with the Royal Borough of Kensington and Chelsea’s conservation team before any formal application is submitted, an agreed specification reviewed and approved in principle by the conservation team, and ongoing conservation team liaison throughout the renovation programme to confirm that the work proceeds in accordance with the consent conditions.
We manage this complete process, pre-application consultation, consent application, conservation team liaison during the programme, and consent condition management at handover, as a standard element of Grade I listed house renovation projects in Belgravia.
House refurbishment for Belgravia properties where the scope is more limited than a full renovation, updating services, refreshing decoration and finishes, addressing specific maintenance items, and improving specific rooms rather than a complete programme covering every element of the building. House refurbishment in a Belgravia listed building still requires listing condition assessment at the start, because even a limited refurbishment programme in a Belgravia Georgian townhouse may encounter original features that require consent or lime plaster that requires correct repair.
Whole house renovation in Belgravia, a complete renovation covering every room on every floor of a Belgravia Georgian townhouse or a significant listed apartment building. Whole-house renovation in Belgravia at this scale produces the most significant and most enduring result of any renovation programme, because every element of the building is addressed in one coordinated programme rather than in a series of partial renovations that accumulate cost and disruption over the years.
The Belgrave Square renovation was a whole house renovation, roof to lower ground floor, all five floors, all ten principal rooms, all three bathrooms, the kitchen, all services, all original feature restoration, all decoration and flooring. Eighteen weeks. One programme. One fixed price.
Period property renovation across Belgravia covering the full range of pre-1914 property types in the SW1 postcode, from the principal garden square Georgian townhouses to the Edwardian mansion blocks on the surrounding streets. Period property renovation in Belgravia requires specific knowledge of the construction methods, materials, and listing conditions of each building type, such as lime plaster on lath in Georgian townhouses, concrete construction in Edwardian mansion blocks, and the specific listing conditions that apply to each.
What Is Included in Our House Renovation Belgravia Service
Roof assessment, repair, and replacement by our in-house roofing team covering Welsh slate repair and replacement, lead valley and parapet flashing, flat roof assessment and replacement, guttering, chimney repair and repointing, and all associated roof fabric. In Belgravia, the roofing work of listed buildings requires a specific assessment of the listing conditions. Roof coverings, chimney stacks, and parapet details are listed elements of many Belgravia buildings and require consent before alteration.
Our roofing team assesses the listing conditions for all external elements at the site visit stage and confirms the consent position before any roof work is specified. Where consent is required for roof covering changes, replacing lead with alternative materials, for example, or altering the chimney stack profile, we manage the application. Where the existing roof covering is specified in the listing conditions, Welsh slate on a Grade II listed Belgravia townhouse, we replace like for like without requiring a consent application.
Structural assessment, engineer coordination, opening formation, party wall matters, and Building Regulations management are all handled by our in-house structural team. In Belgravia, listed buildings, every structural intervention requires both Building Regulations approval and Listed Building Consent. Our structural team carries out the work to the engineer’s specification with Building Regulations sign-off obtained before any structural work is enclosed and within the consent conditions agreed with the Royal Borough of Kensington and Chelsea’s conservation team.
Assessment of the consent requirements for every element of the renovation programme, external roof works, structural interventions, works affecting original features, and any other element that triggers the listed building consent requirement. Application preparation, submission to the Royal Borough of Kensington and Chelsea, pre-application consultation for Grade I properties, conservation team liaison during determination, and consent condition management during the programme.
Listed Building Consent management is included within the fixed price of every house renovation Belgravia project where consent is required, and is not charged as an additional service after the quotation has been accepted.
All plumbing by our Gas Safe registered engineers, new heating system specification and installation, bathroom plumbing on all floors, kitchen plumbing, and gas appliance connections. In Belgravia, listed buildings’ plumbing installation requires specific routing techniques, lime plaster walls cannot be chased with angle grinders, flagstone floors must be cut with diamond equipment, and service runs must be coordinated with the structural and plastering programme to avoid damage to original fabric during installation.
Full rewire, new consumer unit, new circuit installation, bathroom and kitchen electrical work, lighting design, and EV charger installation where required, all by our NICEIC-approved electricians. Part P notification completed. NICEIC installation certificate issued at handover. In Belgravia listed buildings, electrical installation must be routed with minimal impact on original fabric, oscillating tool chase cutting rather than angle grinding in lime plaster, surface conduit where original plaster must be preserved.
Lime plaster repair and reinstatement throughout the specific capability that defines listed building renovation, and that most renovation companies do not have in-house. Lime plaster on lath, the standard wall construction of Belgravia’s Georgian townhouses, must be repaired with lime.
Gypsum applied over lime causes the lime beneath to fail. The 1980s gypsum repairs on three floors of the Belgrave Square townhouse were the direct result of a previous contractor’s failure to understand this basic principle of period building conservation.
Our lime plaster team carries out the complete lime repair process, scratch coat, float coat, and finish coat in hydraulic lime appropriate for the substrate, on every floor of every Belgravia house renovation. No gypsum. No plasterboard over original plaster. No shortcuts that produce visible failures within five years.
Assessment, conservation, and restoration of original listed features throughout the property, including cornicing, ceiling roses, original shutters, original fireplaces, kitchen ranges, flagstone floors, wide-board timber floors, original joinery, and all other surviving original fabric. Our original feature restoration service assesses every element of the existing building fabric at the site visit stage, advising on what is worth restoring versus what is beyond restoration, and carries out the restoration work as an integrated element of the house renovation programme rather than as a preliminary contract.
Bathroom renovation on every floor, all trades in-house, listing condition assessment, lime plaster repair, Gas Safe plumbing, NICEIC electrics, waterproofing appropriate for listed building substrates, tiling, and sanitaryware in specifications appropriate for Belgravia period properties. The Belgrave Square renovation covered three bathrooms across three floors, all renovated sequentially within weeks ten to fourteen of the eighteen-week programme.
Kitchen renovation including listed building consent management, structural opening formation where required, original feature retention and restoration, Gas Safe plumbing, NICEIC electrics, lime plaster repair, and kitchen installation all in-house. The Belgrave Square kitchen retained the original Victorian kitchen range and flagstone floor, both listed features and incorporated them as the defining elements of the new kitchen design.
Complete flooring supply and fit on every floor, engineered wood or herringbone in principal rooms, wool carpet in bedrooms, natural seagrass on staircases and landings, LVT in kitchen and utility areas. All flooring is installed as the final stage of each floor’s renovation programme, not as a separate post-renovation contract, eliminating the gap between renovation completion and flooring installation that, in a multi-company programme, adds weeks to the overall timeline.
Complete decoration throughout all surfaces prepared, all woodwork repaired and painted, all walls decorated in the colours agreed with the homeowner during the renovation programme. Decoration by our in-house team is integrated into the programme, beginning on lower floors as upper floor work continues rather than beginning when the building work is complete.
House Renovation Costs Chelsea
A full Victorian terrace renovation in Chelsea roof assessment and repair, complete rewire, new heating system, one kitchen renovation, two to three bathrooms, plastering throughout, decoration throughout, and new flooring throughout without structural extension or loft conversion: typically £40,000 to £80,000 depending on the size of the property, the extent of roof and structural work required, the kitchen specification, and the bathroom specification.
This is the most common specification for house renovation Chelsea, the mid-terrace Victorian property purchased in need of full renovation, renovated to the standard expected in the Chelsea market, and prepared for either owner occupation or letting. The Flood Street property sat in the middle of this range at completion.
A full house renovation in Chelsea covering all structural work, including any open plan conversions, complete rewire, new heating system, kitchen renovation, three or more bathrooms, full plastering, decoration, and flooring: typically £60,000 to £150,000 depending on the size of the property, the extent of structural work, and the specification of the finished result.
At the upper end of this range, larger Chelsea terraces or townhouses with significant structural work, high-specification kitchens and bathrooms, and premium flooring and decoration, the investment reflects both the scope of the project and the quality standard required to produce a result appropriate for a Chelsea property at the current market level.
A house renovation combined with a rear extension, side return, or loft conversion: typically £80,000 to £250,000 depending on the size and specification of the extension and the extent of the accompanying renovation. Rear extensions on Chelsea Victorian terraces typically cost £40,000 to £80,000 for the structural and building work alone before the renovation of the existing property is costed. Loft conversions typically add £30,000 to £60,000 to the renovation programme, depending on the structural approach and the bathroom specification for the new loft level.
The value-adding potential of renovation with extension in Chelsea is significant. A properly renovated and extended Chelsea Victorian terrace can add £100,000 to £400,000 to the property’s value, depending on the quality of the work and the specification of the result.
The five factors that most significantly affect house renovation cost in Chelsea are the current condition of the roof and structure whether repair or full replacement is required; the extent of the electrical installation that needs to be replaced a full rewire costs significantly more than a consumer unit upgrade and partial rewire; the number and specification of bathrooms; the kitchen specification; and whether structural extension or conversion work is included in the scope.
In Chelsea Victorian terraces, the roof and structural condition is the variable that most frequently surprises homeowners who have not obtained a structural survey before purchasing, because the extent of roof and structural work required in a property that has not been maintained is often greater than a visual inspection suggests. Our free site visit for house renovation Chelsea includes an honest assessment of the roof and structural condition, so the fixed price we quote reflects the true extent of work required rather than an optimistic assumption that will be revised upward during the programme.
House Renovation in Chelsea Period Properties
Victorian terrace renovation in Chelsea is defined by six characteristics that distinguish it from renovation in modern properties. Original Welsh slate roofs requiring specialist assessment and either targeted repair or full replacement, depending on the age and condition of the existing covering. Original solid brick wall construction, no cavity wall, meaning damp management relies entirely on the integrity of the external render or pointing and the internal plaster rather than a cavity break. Original suspended timber floors requiring specific treatment for wet room installations and careful assessment for any additional loads from new stone or tile floor finishes.
Original Victorian plan form typically requires structural changes to meet open plan expectations. Original Victorian services in many Chelsea properties, original cast iron drainage, lead supply pipes in some pre-1900 buildings, and knob-and-tube or early rubber-insulated wiring in properties that have not been rewired since the mid-twentieth century. And original Victorian joinery and plasterwork cornicing, dado rails, architraves, skirtings that require careful protection during the renovation and reinstatement where damaged.
Our Victorian terrace renovation Chelsea team works in these properties every day. The specific knowledge required to renovate a Victorian terrace in Chelsea correctly to protect the period features while modernising the fabric and services is accumulated over years of working in SW3 and the surrounding postcodes, not imported from a generic renovation background.
The correct renovation sequence for a Chelsea Victorian terrace is not optional; it is the only sequence that produces the result without creating problems that have to be undone and redone at additional cost.
Roof and structure first, always. A single rainstorm through an unresolved roof can undo weeks of plastering and decoration below. Structural wall removals must be complete before first fix services are run, because the structural work changes the building layout that the services need to follow.
First fix services before plastering always. Every cable and pipe that runs within the wall or floor structure must be in position before the walls are closed in. Running cables or pipes after plastering means cutting channels, running surface conduit, or lifting floors, all of which are additional costs and damage to work already completed.
Plastering before kitchen and bathroom installation is always. Units installed against wet or unfinished plaster will move as the plaster dries and shrinks. Tile adhesive will not bond correctly to unfinished surfaces. The kitchen and bathroom installation stage must not begin until plastering is complete and dry.
Decoration before flooring is always. Dropping paint on an installed timber floor, dragging ladders across a new stone floor, or spilling adhesive on a carpet are all avoidable if flooring is the last stage before handover. The floor is the last thing installed and the first thing protected on handover day.
Listed building house renovation in Chelsea is the most complex and most rewarding renovation category we work in, complex because the consent requirements add a layer of management that unlisted renovation does not require, and rewarding. After all, the quality of the period building fabric in Chelsea’s listed properties, the craftsmanship of original joinery, plasterwork, and masonry, makes the finished result genuinely exceptional when the renovation is carried out correctly.
Chelsea has a high concentration of listed buildings, Georgian and early Victorian properties on the principal streets and squares of Belgravia and Knightsbridge, mid to late Victorian terraces in the core Chelsea conservation area, and individual listed buildings scattered throughout SW3 and SW10. Every listed building renovation we carry out begins with a detailed assessment of the specific listing conditions, what is listed, what requires consent, and what can proceed under existing permitted development provisions.
Where Listed Building Consent is required, which, for a complete house renovation in a listed Chelsea property, is common, we prepare the consent application, engage with the Royal Borough of Kensington and Chelsea’s conservation team, and manage the consent process alongside the renovation programme. We do not begin work that requires consent until consent is in hand.
Chelsea’s conservation area designation covers the majority of the borough’s residential streets and means that external works associated with house renovation extensions, alterations to rooflines, changes to window specification, and external cladding require planning consent rather than proceeding under permitted development. We advise on the planning position for all external works at the site visit stage and manage planning applications where consent is required.
The Chelsea conservation area also has specific requirements for materials. Replacement windows must match the original specification in material and profile, roofing materials must respect the character of the existing roofscape, and extension materials must be appropriate to the conservation area context. Our renovation team is familiar with the Royal Borough of Kensington and Chelsea’s conservation area guidance and specifies materials accordingly.
Mansion block house renovation in Chelsea, typically involving apartments rather than whole buildings, presents a different set of constraints from terrace renovation. Management company consent is typically required for significant structural or plumbing alterations. Noise restrictions during renovation work are usually restricted to weekday daytime hours, affecting the programme. Waste removal must follow management company procedures. And the concrete frame construction of most Chelsea mansion blocks means that structural alteration possibilities are more limited than in masonry terrace properties.
Our mansion block renovation Chelsea service manages all management company relationships, submitting the required documentation, obtaining consent where needed, and working within the management company’s requirements throughout the programme.
Why Choose Our House Renovation Chelsea Service
Roofers. Structural team. Gas Safe plumbers. NICEIC electricians. Plasterers. Kitchen fitters. Bathroom fitters. Decorators. Flooring installers. All are employed directly by Chelsea Property Renovation & Maintenance Ltd. The Flood Street family’s renovation stalled because four separate contractors each had their own waiting list, and nobody was responsible for eliminating the gaps between them. Our house renovation Chelsea service eliminates the gaps because all trades are in-house, and one project manager coordinates every stage.
Every house renovation Chelsea project has a dedicated project manager who is present on site every working day during active work stages. They know where every trade is in the programme.

They are the single point of contact for the homeowner throughout the renovation and the single point of accountability for every stage of the programme.
The fourteen weeks that the Flood Street family lost to gaps between separate contractors disappeared when we took over, because all trades are in-house, and the project manager sequences every stage with no gap between them. First fix electrics and plumbing completed. Plasterers on site the following week. Kitchen arriving when plastering is complete and dry.

The price on our house renovation Chelsea quotation is the price on our invoice. House renovation projects are the most complex renovation work we do, and the temptation for less scrupulous contractors to present variations and additions during the programme is significant. We do not do this. If we discover something during the renovation that affects the cost, we stop, discuss it with the homeowner, and agree on any change to the price before proceeding. The fixed price we quote is the fixed price we charge.
Every house renovation Chelsea quotation begins with a free site visit and a thorough inspection of the property, covering every element that affects the renovation programme and cost. Roof condition. Structural condition. Existing electrical installation. Existing plumbing and heating. Floor structure. Wall condition. We produce an honest assessment of what the complete renovation requires before we quote, so the price we give you reflects the real extent of work rather than an optimistic figure that grows during the programme.

How much does house renovation cost in Chelsea?
House renovation in Chelsea costs from £25,000 for a focused refurbishment to £250,000 and above for a complete renovation with structural extension. A full Victorian terrace renovation roof, rewire, new heating, kitchen, bathrooms, plastering, decoration, and flooring typically costs between £40,000 and £80,000 without extension work. An extension and loft conversion adds £30,000 to £80,000, depending on the scope. Free site visit and fixed-price written quotation. Call 020 7129 7418.
How long does house renovation take in Chelsea?
A full Victorian terrace renovation without structural extension typically takes ten to sixteen weeks from the start of roofing work to handover, managed by one company with all trades in-house and no programme gaps. With a rear extension or loft conversion, the programme typically extends to sixteen to twenty-four weeks, depending on structural complexity and planning consent timescales. All programme timelines confirmed in the fixed price quotation. Call 020 7129 7418.

Project management is included throughout. The price on the quote is the price on the invoice. Call 020 7129 7418 to arrange a free site visit and programme assessment.
Do you use subcontractors for house renovation in Chelsea?
No. Every trade on every house renovation Chelsea project is employed directly by Chelsea Property Renovation & Maintenance Ltd. Roofers, structural team, Gas Safe plumbers, NICEIC electricians, plasterers, kitchen fitters, bathroom fitters, decorators, and flooring installers, all in-house. No subcontractors. No waiting lists between stages. No coordination between separate companies. One team. One programme. One fixed price. Call 020 7129 7418.
Can you renovate a listed building in Chelsea?
Yes. We regularly carry out complete house renovations in listed buildings across Chelsea and Belgravia. We assess the consent requirements for every listed building renovation at the site visit stage, advising on what requires Listed Building Consent and what can proceed without it. Where consent is required, we prepare the application and manage the process with the Royal Borough of Kensington and Chelsea. Call 020 7129 7418.
What is the correct order to renovate a house in Chelsea?
The correct sequence for house renovation in Chelsea is roof and structure first, first fix electrics and plumbing second, plastering third, kitchen and bathroom installation fourth, second fix electrics and plumbing fifth, decoration sixth, and flooring last. Every stage must be complete before the next begins. This sequence is not optional; departing from it creates problems that have to be undone and redone at additional cost. Our project manager manages this sequence as the core of the renovation programme. Call 020 7129 7418.
Do I need planning permission for house renovation in Chelsea?
Internal house renovation does not require planning permission. Structural work requires Building Regulations approval, which we manage. External alterations, extensions, loft conversions, changes to windows and rooflines require planning consent in Chelsea’s conservation area. Listed building renovation may require Listed Building Consent. We advise on every consent requirement at the site visit stage and manage all applications. Call 020 7129 7418.
Can you take over a stalled house renovation in Chelsea?
Yes. Taking over stalled house renovations is a specific service we provide, assessing the current state of the programme, identifying what has been completed correctly and what needs to be redone, and providing a fixed price for the remainder of the renovation with a realistic completion date. We took over the Flood Street renovation eighteen months into a programme that had stalled and completed it in four months. Call 020 7129 7418.
How do I choose a house renovation company in Chelsea?
The three questions that matter most when choosing a house renovation company in Chelsea are: do they have all trades in-house or do they subcontract, is there a single project manager responsible for every stage, and is the price genuinely fixed? A company that subcontracts trades cannot eliminate programme gaps. A company without a dedicated project manager cannot sequence a multi-stage renovation without the gaps that turned the Flood Street renovation into an eighteen-month project. Call 020 7129 7418.
What is the difference between house renovation and refurbishment?
House renovation typically involves significant changes to the structure, services, and layout of the property, new roof elements, rewiring, a new heating system, structural wall removals, a new kitchen, and new bathrooms. House refurbishment typically involves updating the finish of a structurally sound, serviceable property, new kitchen, new bathrooms, decoration, and flooring. Both are services we provide across Chelsea. The correct scope for your property is something our project manager assesses during the free site visit. Call 020 7129 7418.
Can you manage a house renovation while we are living in the property?
Yes, depending on the scope of the renovation. A complete renovation involving roof work, structural changes, and full rewire is typically not compatible with occupying the property is not habitable during these stages. A focused refurbishment, new kitchen, new bathrooms, and decoration can often be phased to allow occupation of rooms not currently being worked on. We advise honestly on the occupation question during the free site visit based on the specific scope of work proposed. Call 020 7129 7418.
Is your house renovation work guaranteed?
Yes. All house renovation Chelsea work is guaranteed for 12 months from completion, covering all labour and installation. Structural work receives Building Regulations sign-off. Gas Safe certification is issued for all gas and plumbing work. NICEIC Part P certificate issued for all electrical work. All appliance and product manufacturer warranties are provided at handover. Every certification needed for insurance, mortgage, or resale purposes is issued on handover day. Call 020 7129 7418.
