Flat Refurbishment South Kensington

Flat refurbishment is the everyday renovation job in South Kensington, because 85% of homes here are flats and 84% of all homes date from before 1919. Most flats here therefore sit inside period buildings, whether a house split into flats or a purpose-built block, with a smaller post-war and modern share. The work happens inside a building you share: the lease, the managing agent, the neighbours below and the common stair shape the programme as much as the kitchen, bathroom and wiring you are renewing.

For South Kensington, published UK averages put a full flat refurbishment at £33,000 to £48,000 and a basic one, with budget kitchen and bathroom fittings, at £15,000 to £18,000, and London flats usually cost more (Checkatrade and MyJobQuote, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in South Kensington: we refurbish the flat within the terms of your lease and licence to alter, protect the common parts throughout, and a registered electrician certifies the new consumer unit and circuits.

Which buildings South Kensington flats sit in, and why it matters

The building type decides what you can touch. In South Kensington 85% of homes are flats, 84% of homes were built before 1919, 12% after 1945 and only 3% in 2000 or later. So a flat here is most likely in a period building, either a former single house now split floor by floor, or a purpose-built period block. A converted house tends to have shared timber floors and services crossing between flats. A later block has concrete floors and risers controlled by the freeholder.

That difference changes the scope before any design. In a converted house, lifting floorboards for a rewire can expose the ceiling of the flat below, so the order of opening up is agreed with the neighbour and the agent. In a concrete block, chasing and coring need consent, and new pipe runs must stay inside the flat. We check the building type at survey, then write a scope that keeps every change on your side of the demise.

Housing in South Kensington

Around 8,840 homes make up South Kensington on the valuation list; 85% are flats and 15% houses, and 84% date from before 1919, 3% from between the wars and 12% from after 1945.

Licence to alter, managing agents and block hours in South Kensington

Read the lease before booking a start date. Leases commonly need the landlord's written licence to alter for work to structure, shared services or floor finishes, and the managing agent often asks for drawings, a method statement and the contractor's details first. That approval can take weeks, so the licence request goes in as soon as the scope is fixed. We prepare the method statement and programme the agent asks for, and keep to the conditions attached to the licence.

Block rules then set the daily routine. The council's Final Draft Code of Construction Practice already limits noisy work audible at the boundary to 8am to 6pm on weekdays, with none at weekends, and a block's own rules may set tighter hours for drilling inside the building. We protect the common parts and any lift with boards and sheeting, carry materials up the stair at agreed times, and bag rubbish for removal rather than leaving it in the hall.

Sound, fire doors and leaks in a shared South Kensington building

A new hard floor needs sound insulation under it. Laying timber or stone where there was carpet in a South Kensington period building can carry footsteps straight through old joists to the flat below, and a lease may require the original acoustic performance to be kept or improved. We fit an acoustic underlay or a floating floor build up under hard finishes, isolate skirtings from the floor, and seal gaps around pipes so sound does not bypass the new layer.

Fire safety inside a block is shared. The flat entrance door and the compartment walls around your flat are generally matters for the freeholder or the building's responsible person, so any change to them goes through the agent. Inside the flat, new services must not open holes through compartment floors without fire stopping. Leaks are the other risk: every new waste and supply is pressure tested before the floor closes, and the flat below is inspected with the neighbour's agreement before and after.

Letting a South Kensington flat: MEES, EPC and licensing

A let flat has to meet a minimum energy rating. GOV.UK says that since 1 April 2020 landlords cannot let, or continue to let, a property covered by the MEES Regulations with an EPC rating below E without a valid exemption. The council can issue a financial penalty to a landlord who fails to comply. For a period flat in South Kensington, secondary glazing, draught stripping, heating controls and efficient lighting are measures that fit without changing the facade.

Licensing can apply to a flat too. In Kensington and Chelsea every privately rented home occupied by three or more people forming two or more households who share facilities must be licensed. Even with five or more sharers, a purpose-built flat in a block of more than two self-contained flats falls under the Additional HMO licensing scheme, in force since 1 June 2023, rather than the Mandatory one. If you plan to let to sharers, the licence conditions become part of the refurbishment brief, and the owner or their agent makes the application.

• Kitchen renewal within the flat footprint, drained to the shared stack
• Flat entrance door replaced as a certified fire door set, with the freeholder's written agreement
• Unvented cylinder replacement, notified to building control
