With 83% of homes recorded as flats across the Hans Town and Brompton statistical areas that cover Knightsbridge, flat refurbishment is the main kind of renewal work here. Much of the local housing is prestige residences and mansion blocks, and the flats sit in those blocks, in period houses divided into apartments and in a smaller number of post-war buildings. Each one shares walls, floors, a staircase and often a lift with neighbours. The work is planned around the lease, the managing agent's block rules and the borough's construction hours before anything is stripped out.
For Knightsbridge, 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 Knightsbridge: 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.

The kinds of Knightsbridge block and what each brings
The age of a Knightsbridge block tells you what the refurbishment will meet. 66% of homes in the wider Hans Town and Brompton statistical areas were built before 1919, so older flats sit either in purpose-built Victorian and Edwardian mansion blocks or in townhouses split into flats later. Mansion block flats tend to have solid internal walls, timber floors on deep joists and shared risers; converted houses bring irregular floor levels and services that were rerouted when the house was divided, sometimes through the flat above or below.
In those same statistical areas the interwar share is 19%. Interwar mansion blocks often bring their own pattern: steel window frames, concrete floors with screeds that crack, and original risers shared with the flats above. Post-war homes make up 15%, and there the issue can be tired services more than failing structure. Only 2% of homes date from 2000 or later, so a recent tower is the exception here. In any higher-risk building, meaning a block of seven or more storeys or eighteen metres or more with at least two homes, the Building Safety Regulator is the building control authority for building work, except work done under a competent person scheme.
Housing in Knightsbridge
Count the homes in Knightsbridge and you get about 10,560: 15% built since 1945, 19% between the wars and 66% before 1919, with flats at 83% and houses at 17%.
Leases, licence to alter and block rules in Knightsbridge
The lease decides what you may change in a Knightsbridge flat, and the freeholder's licence to alter turns that into conditions. Leases differ: some bar structural work outright and some permit non-structural work without consent, but works touching structure, services, windows or floor finishes usually need the landlord's written consent, granted through the managing agent after they review drawings and a method statement. The licence often sets working hours tighter than the borough's, requires protection to common parts and names a surveyor who inspects the finished work. We prepare the method statement and programme the agent asks for, and the start date follows the signed licence.
Floors are the clause most likely to shape the specification. Many leases require carpet or an acoustic underlay under any hard floor so that footfall does not carry to the flat below, and the agent may ask for a tested product. In a Knightsbridge mansion block with timber floors, that means an acoustic layer and a floating floor, which raises floor levels by a few centimetres and affects door thresholds and skirtings. Settling this at the licence stage avoids refitting a finished floor.
Getting materials in and waste out of a Knightsbridge block
Logistics in a Knightsbridge block run through shared stairs, a lift sized for residents and a front door on a busy street. We line the lift car, landings and stair treads before the first delivery, keep a clean route for residents, and remove waste in sealed bags on the days agreed with the porter or managing agent. Long items such as worktops, doors or sheet materials are measured against the stair turn before ordering, because not every mansion block stair takes a full-length board.
Outside, a skip is often impractical in front of a mansion block, so waste leaves in bags or by a wait-and-load collection, and delivery vans need a kerbside space. The council suspends parking bays for building or maintenance works where tradespeople use vans, not cars, so we book those days in advance. Inside, the managing agent sets the lift booking and quiet hours, and the porter needs notice of each delivery. We write all of this into the method statement so the agent approves it once.
Refurbishing a Knightsbridge flat to let under MEES
A landlord refurbishing a Knightsbridge flat to let needs the finished home to clear the minimum energy efficiency rules. 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. The refurbishment is the practical moment to fix the items that drag a rating down, such as old electric heaters, draughty windows and uninsulated top floor ceilings.
Licensing can also set the standard of the finished flat. In Kensington and Chelsea every privately rented property occupied by three or more people living as two or more separate households who share facilities must be licensed. A Knightsbridge flat let to sharers therefore comes with licence conditions on fire safety and amenities. The landlord or their agent applies for the licence. We build the kitchen, bathroom, electrics and fire detection to the conditions it sets, with a registered electrician certifying the installation.

- Buy-to-let refurbishments between tenancies, with the EICR and gas safety record arranged with the certifying engineers
- Electric heating upgrades: high retention heaters, or a heat pump where the building allows

FAQ
Frequently Asked Questions about Flat Refurbishment Knightsbridge
What should I budget to refurbish a flat in Knightsbridge?
Use the UK range of £33,000 to £48,000 for a full refurbishment (Checkatrade and MyJobQuote, 2026) as a floor, and add for London prices and for what the block requires. The licence to alter is between you and your freeholder, so any fee they charge sits outside the building quote. The Knightsbridge survey fixes the scope, and each trade is priced as its own line.
Do you need a licence to alter before refurbishing a Knightsbridge flat?
Usually, where the flat is leasehold and the works go beyond decoration, though leases differ and some permit non-structural work without consent. The lease sets what needs the landlord's consent, and the landlord, usually through the managing agent, grants a licence to alter with conditions on hours, protection and method. We supply the method statement and programme the agent needs, and the work starts once the licence is signed.
Which EPC ratings stop a landlord letting a Knightsbridge flat?
F and G. 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, and the council can fine a landlord who fails to comply. A refurbishment is the time to lift the rating, and we install the measures your energy assessor recommends.
How much of Knightsbridge housing is flats?
Across the Hans Town and Brompton statistical areas that cover Knightsbridge, the VOA list records 83% of homes as flats against 17% houses. Much of the local stock is prestige residences and mansion blocks. For a refurbishment that means shared walls, floors and entrances in almost every job, and a lease and managing agent to satisfy before work begins.
Does a Knightsbridge flat let to sharers need a licence?
Yes, if three or more people from two or more households rent it and share facilities. That licensing rule runs across Kensington and Chelsea. The landlord or their agent applies, and the licence conditions then set standards for fire detection, kitchens and bathrooms, which we build to as part of the refurbishment.
What hours can loud work run inside a Knightsbridge mansion block?
Weekdays from 8am to 6pm for noise audible at the site boundary, under the borough's Final Draft Code of Construction Practice, with none at weekends or on public holidays. Breaking out is held to 9am to noon and 2pm to 5:30pm. Block rules are often tighter, for example no drilling before 9am, and we work to whichever limit is stricter.
What stops water from a new bathroom leaking into the flat below?
Tanking and testing before anything is tiled. We waterproof the shower area and floor with a membrane, pressure test new pipework before it is boxed in, and fit accessible isolation valves. In an older block with timber floors, a leak spreads quickly into the ceiling below, so we also check the existing waste routes and joist condition when the bathroom is stripped.
Can you replace the heating in a flat with no gas supply?
Yes. Flats without gas usually run on electric heating, and the choices are storage heaters with modern controls, panel heaters, or a heat pump where the lease and the building allow an external unit. The choice affects the EPC, the electrical load and the consumer unit, so we plan it with the electrician and any energy assessor before the walls are closed. For a let flat, since 1 April 2020 the EPC must be E or better for existing lets as well as new ones, unless an exemption is registered.
How do you protect the common parts of a Knightsbridge block?
We fit protection to the lift car, stairs, landings and entrance before any materials arrive, and keep it in place until the last delivery. Waste leaves in sealed bags on agreed days, and the route is cleaned at the end of each working day. The managing agent or porter inspects the common parts with us at the start and end of the job.
