Flat Refurbishment in Knightsbridge: What You Need to Know
Refurbishing a Knightsbridge flat is not the same as refurbishing a house. The Licence to Alter is usually required before a single brick moves, Part E of the Building Regulations dictates floor and ceiling build-ups, and site logistics must account for lift protection, works-hours restrictions, and neighbour disruption. Our team manages freeholder surveyors, Party Wall awards, and Westminster, RBKC Building Control in parallel so your project starts cleanly and finishes without disputes.
International luxury quarter between Hyde Park and South Kensington. Mix of grand period buildings and modern luxury developments. Split between Westminster and RBKC. A full refurbishment in Knightsbridge typically involves stripping the property back to its structural shell, upgrading mechanical and electrical services, reconfiguring layouts, and finishing to the highest standard — all while preserving and restoring original period features.
Our Knightsbridge refurbishment projects are managed through a single point of contact, coordinating architects, structural engineers, M&E specialists, and specialist subcontractors. We work within Westminster's planning and building control requirements to deliver on time and on budget.
Flat refurbishment in Knightsbridge: what actually drives the project
Knightsbridge combines Regency and Victorian townhouses with prime mansion flats around Lowndes Square, Cadogan Place and Wilton Place, where many buildings are listed, leasehold or estate-controlled.
Knightsbridge sits within RBKC conservation areas, where external change and basements are tightly controlled. Estate or freeholder consent and Licence to Alter requirements often run alongside planning and Building Regulations.
Cost is driven by high specification, RBKC-compliant basement works, acoustic separation in mansion blocks, conservation-grade external work and party-wall awards with close, high-value neighbours.

What a Flat Refurbishment Involves
Refurbishing a flat means renovating inside a building you share — so the job is as much about leases, neighbours and building rules as it is about kitchens and finishes. We plan every project around the consents your lease demands and the protocols your block expects, then deliver the technical work under one fixed-price contract. A typical scope covers the elements below.
- Licence to Alter — lease review, application pack and freeholder’s surveyor queries handled on your behalf
- Acoustic build-up — separating floors and walls upgraded to meet Building Regulations Part E and any stricter freeholder schedule
- Wet-room tanking — certified waterproofing beneath every bathroom, flood-tested before tiling and covered by a 12-month defects period
- Rewire & replumb — new circuits, pipework and heating, coordinated with the building’s risers and stacks
- Layout changes — internal openings engineered, approved by building control and cleared with the freeholder where the lease allows
- Kitchens & bathrooms — designed, supplied and fitted to the specification tier you select
- Period detail — cornicing, sash windows and fireplaces retained and repaired in conversion flats
- Block protocols — lift protection, booked deliveries, restricted noisy hours and daily cleaning of communal areas
How We Run Your Project
Six stages, sequenced so freeholder consent never holds up the start on site.
- Survey & lease review — we measure the flat, inspect the services and read your lease to identify exactly which consents apply.
- Design & consents — our architects develop the layout while the Licence to Alter application runs in parallel, not afterwards.
- Fixed-price contract — an itemised specification agreed in full, with the acoustic and tanking details written in.
- Strip-out & first fix — soft strip, structural openings, cabling, pipework and the acoustic carcass, all removed and delivered through agreed routes.
- Second fix & finishes — kitchen, bathrooms, joinery, flooring and decoration.
- Testing & handover — snagging, certification and reinstatement of any communal areas before the keys come back to you.
Read the full flat refurbishment guide for flat typologies, specification tiers and the Licence to Alter process in detail.
Almost every leasehold flat needs formal freeholder consent — a Licence to Alter — before structural work, new flooring or services alterations can begin, and proceeding without one puts your lease at risk. Building Regulations apply on top: Part E sound insulation between dwellings, electrical and heating sign-off, and fire safety where walls or floors are opened. Flats and maisonettes also have no permitted development rights, so external changes always need a planning application. Our planning guide library covers the rules borough by borough.
Why Hampstead Renovations
Flat refurbishment rewards a team that already knows what freeholders and managing agents will ask for.

Every contract is fixed-price on JCT terms, backed by £10M public liability insurance — the level major London freeholders require — plus a 12-month defects period and a 10-year workmanship warranty. Enquire before 2pm on a weekday and we will call you back the same day.

Flat Refurbishment in Knightsbridge: Questions
Do I need a Licence to Alter to refurbish a flat in Knightsbridge?
Almost certainly, yes. Knightsbridge flats sit on estate-controlled or freeholder-held land, and estate or freeholder consent — with a Licence to Alter for the flat itself — runs alongside planning permission and Building Regulations rather than replacing them. We prepare the licence application in parallel with the statutory consents so that neither holds the other up.
What kinds of Knightsbridge flats do you refurbish?
The great mansion blocks hold some of the most valuable leasehold flats in London, set among the grand stuccoed and red-brick terraces of Lowndes Square and Cadogan Place and the elegant houses of Wilton Place and Montpelier Square. In the blocks, structure, acoustics and freeholder or estate consents are handled as one exercise — the finish is exacting, and so is everything behind it.
Which planning rules apply to a flat refurbishment in Knightsbridge?
Knightsbridge falls within the Knightsbridge Conservation Area under the Royal Borough of Kensington and Chelsea, with the Cadogan and other estates holding much of the land. The conservation area and Article 4 controls shape any external change, so the consent strategy leads the project — we settle it with the council and the estate before the design is finalised.
How much does a flat refurbishment cost in Knightsbridge?
Guide rates in Knightsbridge are £900–£1,700/sqm excluding VAT, with a full two-bedroom refurbishment typically between £60,000 and £110,000, over a 16–32 weeks programme. A written scope and site assessment come before any fixed price.

Local character & heritage: renovating flats in Knightsbridge
Knightsbridge sits in the City of Westminster and the Royal Borough of Kensington & Chelsea, and a large share of its homes are leasehold flats — within grand stucco and red-brick mansion flats and townhouses. Refurbishing one is a full interior project: reconfiguring the layout, renewing services and finishes, and often combining or reworking rooms within the existing footprint.
The work runs under the lease, so the freeholder's or managing agent's consent sits alongside Building Regulations and the Party Wall Act usually applies between flats; external elements such as windows stay controlled in conservation areas. Because most homes are high-value leasehold flats and a large share are listed, we coordinate the lease, the freeholder and the build as one fixed-price contract.

Flat Refurbishment in Knightsbridge: Planning & Local Context
the Royal Borough of Kensington & Chelsea · SW1X/SW7
Planning for flat refurbishment in Knightsbridge
Flat refurbishment in Knightsbridge sits across two consent regimes: the Royal Borough of Kensington & Chelsea for planning and building control, and your freeholder for a licence to alter covering structural changes, new services and floor build-ups — essential within Knightsbridge's conservation areas and most mansion blocks.
the Royal Borough of Kensington & Chelsea context
Knightsbridge SW1X/SW7 sits within Knightsbridge's conservation areas, and the Royal Borough operates one of the country's strictest planning regimes — its basement policy limits excavation to a single storey beneath the footprint, and listed-building and conservation control is extensive. Knightsbridge straddles the Royal Borough and Westminster, so the authority depends on the street. Our in-house RIBA Chartered Architects prepare and submit every application to the Royal Borough of Kensington & Chelsea and handle pre-application discussions where early planning advice is useful.
Building Regulations
Flat Refurbishment in Knightsbridge must satisfy Building Regulations — covering sound insulation to Part E, fire compartmentation to Part B, and certified electrical and plumbing works. Our in-house engineers manage Building Control from initial notice to completion certificate.
