GS Renovation carries out whole-house refurbishments throughout Chelsea, on the Georgian and Regency townhouses that line the streets around the King's Road. One team manages the rewiring, replumbing, replastering and structural work, restoring period features while bringing these listed and conservation-area homes up to modern standards.
In Chelsea, a full house refurbishment typically costs £40,000 to £150,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Chelsea: we carry the structure, services and finishes as one contract.
The two rooms that cost the most have their own pages, with prices: kitchen renovation in Chelsea and bathroom renovation in Chelsea. With 79% of homes in Chelsea flats, the soil stack usually fixes where a bathroom can go, and the lease may need the freeholder's consent for either room.

Whole-house refurbishment in Chelsea townhouses
A full refurbishment of a Chelsea townhouse often spans several floors, from a lower-ground kitchen to the bedrooms and bathrooms above. We strip back and renew the services first, rewiring and replumbing throughout, then replaster and reconfigure dated layouts to suit how families live now. Because these SW3 properties are tall and narrow, careful sequencing matters, so we plan the structural work, first-fix, second-fix and decoration in the right order to keep the project moving. The same applies to a flat in a mansion block or converted house, where the kitchen and bathroom renovations usually set the programme, so they are planned with the services and any structural change rather than as separate jobs.
Chelsea's Georgian and Regency houses retain features worth keeping, such as cornicing, ceiling roses, sash windows, panelled doors and cast-iron fireplaces. Where these survive we restore them, and where they have been lost we can reinstate period detailing in keeping with the age of the house. This matters especially in listed buildings, where original fabric is protected. We balance sympathetic restoration with modern insulation, heating and wiring so the home is both characterful and comfortable.
Housing in Chelsea
Of the 12,410 homes the valuation list records in Chelsea, 57% were built before 1919, 11% between the wars and 31% since 1945; 79% are flats and 21% are houses. Since most homes here are flats, a whole-flat refurbishment in Chelsea works to the lease: the freeholder's licence for alterations, agreed working hours and sound insulation between floors.
Replacing windows during a Chelsea refurbishment
Sash windows are easy to leave until last in a Chelsea whole-house renovation, but they can change the paperwork. The council has consulted on a Windows Local Development Order to remove the need for separate planning permission to change existing windows in non-listed residential properties across the borough. Check whether it has been made, and on what conditions, before relying on it. Whatever its status, the council's Householders' Guide to windows states that building regulations apply to all replacement windows, so new sashes need to meet current requirements and be certified or approved.
Listed homes follow another route. The borough has over 4,000 listed buildings, and window changes to a listed building normally need listed building consent. Under the draft window Local Listed Building Consent Order, similar works to Grade II* buildings would still require an application. In a Chelsea house listed at Grade II*, window work belongs in the same consent package as the rest of the refurbishment. For a Grade II house, check whether the order has been made and what it covers. Order the joinery only once the consent and the building regulations route are both settled, because sash boxes are made to measure.
Coordinating trades across Chelsea projects
The advantage of a whole-house renovation in SW3 is that one contractor sequences everything, avoiding the delays and finger-pointing that come with hiring separate trades. We coordinate electricians, plumbers, plasterers, joiners, tilers and decorators under a single programme, so the kitchen, bathrooms, structural openings and decoration all come together. In the occupied streets near the King's Road, we also manage deliveries, skips and parking carefully to keep good relations with your neighbours.
Renovations of this scale usually include structural changes, such as removing walls between reception rooms or opening up the lower ground floor. Those elements need Building Regulations approval and building control inspections, and where a shared wall is affected the Party Wall etc. Act 1996 applies. Internal cosmetic work does not need planning permission, though listed properties in the Royal Borough of Kensington and Chelsea need listed building consent for internal works that affect their character, which we identify at the outset.

FAQ
Frequently Asked Questions about Home Renovation Chelsea
Is the price of home renovation higher in Chelsea than elsewhere in Central London?
Location is not a line on a home renovation quotation in Chelsea; two Central London homes of the same age get similar figures within £40,000 to £150,000 or more (indicative). What separates them is condition and access at the SW3 address, and the approvals route, since the work needs Part P notification for the rewire and Royal Borough of Kensington and Chelsea building control sign-off. There is no travel surcharge within Kensington and Chelsea.
Can you renovate my whole Chelsea townhouse while keeping its period features?
Yes. We renew the wiring, plumbing, plaster and layout while carefully protecting and restoring original features such as cornicing, sash windows and fireplaces. In listed SW3 homes this is essential, as original fabric is protected. We handle the building regulations side and work with you on any listed building consent, sequencing structure, services and finishes so the house is modernised without losing its Georgian or Regency character.
What happens to sound between flats when floors are lifted in a Chelsea renovation?
It gets worse unless the floor is rebuilt with care. Floors between flats in converted period buildings often hold pugging, a fill laid between the joists that deadens sound. Once boards come up for rewiring or new pipes, that fill is kept or replaced with acoustic insulation, and the boards refixed so they do not creak. Flats are 79% of Chelsea's dwellings, so the neighbour below usually notices the difference.
How should damp be tackled in a Chelsea lower ground floor during a renovation?
Diagnose before specifying. Lower ground rooms sit against earth, so their walls take on moisture from outside as a matter of course. Existing tanking or cavity membranes are inspected and repaired, any sump pump is tested, and airflow is improved with ducted extraction. New finishes go on only once the room has dried, otherwise salts and staining appear behind new plaster within months of moving back in.
Can a Chelsea period home be rewired without wrecking its lath and plaster ceilings?
Largely, yes. With floorboards lifted above, cables are fished through the joist voids and dropped to new light positions from above rather than chased up from below. Where a ceiling must be opened, the lath is cut back to a joist and repaired with a compatible backing plaster instead of gypsum patches, which crack at the joint. All of this is first fix, finished before any decorative plaster is restored.
What heating and hot water system suits a tall Chelsea townhouse?
Normally one with stored hot water. A combi boiler heats water on demand and struggles when bathrooms on different floors run together, and pressure falls off towards the top of the house. A system boiler feeding an unvented cylinder keeps the pressure up at every level. The decision comes before first fix, because it sets pipe sizes, the cylinder cupboard and every route up the building.
Does repairing Chelsea sash windows avoid the rule on replacement windows?
Repair is worth pricing first, because the rule bites on replacement. The council's Householders' Guide to windows states that building regulations apply to all replacement windows. Overhauling existing sashes, splicing in new timber where it has rotted, renewing cords and adding draught-proofing keeps the original window in place. In a Chelsea house where the sashes are original, a joiner's condition report on each window shows which can be repaired and which genuinely need replacing.
What should a Chelsea flat owner send the managing agent before a renovation?
A short pack: the scope, drawings for anything structural, the programme with the noisy days marked, the contractor's insurance details and how the common parts will be protected. With 79% of Chelsea's homes being flats, a renovation here is usually inside a managed building, and a licence to alter is often needed before structural or services changes. Sending the pack early lets the licence run alongside the design instead of holding up the start date.
What should be recorded before a Chelsea period interior is stripped out?
Everything that would be hard to reinstate: cornice and skirting profiles, panelled doors, shutters, fireplace surrounds and the layout of the rooms. Photographs with a scale, measured sketches and a short schedule take a day and pay back twice. The borough has over 4,000 listed buildings, and in a listed house the record supports the consent application and shows what was there. In any Chelsea house, it gives the joiner and plasterer the exact profiles to match later.
