Flat Refurbishment Kensington

Flat refurbishment is the everyday case in Kensington. Across the VOA statistical areas of Kensington Abingdon and Kensington Gardens, 85% of homes are flats, from period mansion flats to divided stucco houses, and 19% date from after 1945. Renewing a flat means working inside a building you share. The lease and the managing agent set when and how work happens, the lift and common stairs need protecting, and the flat below is the neighbour who hears and feels every mistake. We plan the licence to alter, access and sequence first, then renew the flat inside its own walls.

For 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 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.

Refurbishing a Kensington mansion flat under a lease

A refurbishment in a Kensington mansion flat starts with the lease, not the kitchen catalogue. A lease normally requires the landlord's written consent, a licence to alter, for structural work and often for changes to the layout or services, so read yours before anything is designed. The managing agent will usually ask for drawings, a method statement and the contractor's details, and will set working hours before anyone arrives. Moving a bathroom, lifting floorboards or touching a structural wall are the changes they tend to look at hardest.

We prepare the method statement and programme for your application and work to whatever conditions come back: protection to the common parts, lift bookings, and waste taken out at agreed times. Floor sound insulation is the usual flashpoint in these blocks. Where hard flooring replaces carpet, the lease often asks for an acoustic underlay or a floating floor, and we build that in from the first fix so the flat below is not the one who finds the problem.

Housing in Kensington

By the valuation list's count, Kensington holds about 9,000 homes, 15% houses and 85% flats; by age, 75% were built before 1919, 6% between the wars and 19% since 1945.

Block rules, lifts and deliveries in a Kensington building

Inside a Kensington block the working day is set by two sets of rules, and the tighter one applies. The borough's weekday window for loud work is the outer limit, and a block's own rules can shorten that with a later start, a quiet lunch hour or no drilling on certain days. We ask the managing agent for the block's rules in writing and build the loud tasks into the hours that are left.

Getting materials in and waste out is the other daily constraint. Plasterboard, tiles and kitchen units go up the common stairs or in a lift booked and protected for the purpose, and floors, walls and door frames on the route are covered before the first delivery. Where the trades arrive by van, the council can suspend a parking bay for the building work, which saves carrying bags past the porter's desk from the next street. Waste leaves in bags at agreed times, since a skip rarely fits outside a mansion block entrance.

Letting a refurbished Kensington flat and the EPC floor

A landlord refurbishing a Kensington flat between tenancies should treat the EPC as part of the scope. The council states it is unlawful to rent out a domestic property with an EPC rating of F or G without a valid exemption, and it can issue a financial penalty to a landlord who fails to comply with the MEES regulations. Since 1 April 2020 that has covered continuing lets as well as new ones. An old flat with single glazing and electric storage heaters can sit near that line.

The practical response is to sequence the energy work while the rooms are empty: insulation behind new linings on cold external walls, detailed for solid brick so damp is not trapped, better heating controls, and draught sealing to sashes. Electric heating in a flat without gas is replaced with efficient panel or storage heaters on a new circuit, or a gas boiler is renewed by an engineer on the Gas Safe Register. If the building is listed, linings, insulation, joinery, floors and sashes that affect its character need listed building consent, which the owner or their designer applies for, so check the listing before the specification is fixed. A registered domestic energy assessor issues the new certificate afterwards. Keep the old certificate and the new one together for any later letting or sale.

Licensing and fire safety for a Kensington flat in a block

Letting a Kensington flat to sharers brings in the borough's HMO licensing, which our HMO conversions page covers, so the licence conditions belong in the scope before a flat is relet. For an ordinary let the refurbishment still has to leave the flat safe to live in. That means a new consumer unit with the protection current wiring rules require. It also means mains wired smoke alarms where the electrics are renewed, a carbon monoxide alarm beside any gas boiler, and extract fans in the kitchen and bathroom sized for the room so condensation does not return.

Fire safety inside a block is shared ground. The flat entrance door and the walls and floors that enclose the flat protect the whole building, and in general law they are matters for the freeholder or the responsible person as well as for you. A refurbishment therefore leaves the entrance door alone unless the freeholder agrees a replacement fire door, and every new hole for pipes or cables through a separating wall or floor is fire stopped. In a higher-risk building, building control for the works sits with the Building Safety Regulator, and certain competent person scheme types cannot be used there, so the route for each item is confirmed first.

• Consumer unit replacement from the meter onwards
• Electric heating upgrades: high retention heaters, or a heat pump where the building allows
• Flat entrance door replaced as a certified fire door set, with the freeholder's written agreement
