Kitchen Renovation Westminster

GS Renovation designs and builds kitchens across Westminster, from the townhouses of Mayfair and Belgravia to the mansion flats of Marylebone and Pimlico. We handle cabinetry, worktops, services and any structural work as one project, fitting kitchens that suit period proportions and modern living alike.

In Westminster, a kitchen renovation typically costs £18,000 to £60,000 or more from design to fitting (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Westminster: we carry the strip-out, services and fit as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Westminster home and an itemised quote.
2. Strip-out and any structural work, first-fix plumbing and electrics, plastering.
3. Units fitted and levelled; stone worktops templated and cut off site.
4. Worktops, appliances, tiling and second fix. Electrics certified under Part P by a registered electrician, or notified to building control. Typically 3 to 5 weeks on site.

Open-plan kitchen-diners in Westminster homes

The most requested Westminster kitchen project opens up a lower-ground or rear floor to create a bright, sociable kitchen-diner. Because the dividing wall is usually load-bearing in these Georgian and Victorian houses, we install a steel beam sized by a structural engineer and signed off by building control. The result turns a run of small, dark rooms into a single connected space that works for the whole family.

We fit quartz, granite or composite worktops, integrate appliances neatly and plan plumbing, electrics, tiling and lighting so the finished kitchen feels considered rather than assembled. Any new kitchen circuits are notifiable, so they are certified by a registered electrician under Part P. In listed homes across SW1 and W1, we make sure structural changes respect the protected fabric of the building.

Housing in Westminster

Count the homes in Westminster and you get about 132,230: 40% built since 1945, 10% between the wars and 48% before 1919, with flats at 91% and houses at 9%. Since most homes here are flats, a kitchen in a flat in Westminster drains to the building's shared soil stack, while a new extract through the outside wall needs the freeholder's licence first.

Kitchen fit outs in Westminster and the District Surveyors' charge

Westminster's District Surveyors publish a minor works charge for the fit out of a bathroom or kitchen in one property, on either a building notice or a full plans application. For a Westminster kitchen that is a useful reminder that a fit out can need building control even when no wall comes out. What usually brings it in is a new circuit, new extraction, a drainage change or a change to the protection of an escape route. Where any of those applies, the application goes in before the old kitchen is stripped out. A new circuit alone can instead be self-certified by an electrician registered with a competent person scheme.

The completion certificate depends on paperwork from other trades. Westminster issues it only once all fees due have been received and all relevant electrical and gas certificates have been supplied, so a kitchen with a new induction circuit or a gas hob stays open until those certificates arrive. We collect them the week each trade finishes and send them with the final inspection request. In a flat that can matter for the licence to alter too, since the freeholder may want the completion certificate before the licence file is closed.

Bespoke kitchens for Westminster proportions

Westminster's Georgian and Regency homes come with tall ceilings, deep alcoves and chimney breasts that suit made-to-measure, in-frame cabinetry far better than off-the-shelf units. We plan the layout around the room's period features and its natural light, whether that is a grand first-floor space in a Marylebone townhouse or a compact galley in a Pimlico mansion flat.

For leasehold kitchens in NW8 and W9, we coordinate with the managing agent on access and building-management rules, and give real thought to sound insulation and waterproofing where a kitchen sits above another flat. From handleless contemporary designs to classic Shaker, we build to suit the age of the property, with every trade run by our own team from first fix to final tile, and the electrics certified by a registered electrician.

What a survey turns up in W1

Surveying a kitchen in a Westminster mansion flat tends to raise the same set of issues. The waste runs into a stack shared with other flats, so any change to the position of a sink or a washing machine has to work with that stack rather than around it. Water pressure varies with height in the block. And the electrical layout is often original even where the consumer unit itself has been replaced.

In a townhouse the questions are different. Kitchens sit at lower ground level, where damp and limited natural light govern the design, and the structure above may already have been altered more than once. In both cases we check what the lease permits before drawing anything, because in W1 and SW1 the restriction that stops a layout is at least as often legal as it is structural. Ceiling voids are worth opening early in either case, since they usually decide whether an extract duct can go where you want it.
