They have been extremely efficient and reassuring. It was a complex project but they took it all in their stride. They recommended very good contractors who were all punctual, polite and capable.

Having the Beams team on hand to manage the project and provide extra reassurance on build decisions was incredibly helpful and made the whole experience stress free.

All about trust. I felt comfortable with my money, my project, and my home knowing that the outcome would be to my satisfaction or would be made good.

Vetted builders in Kensington, not one-size-fits-all
Kensington runs from the grand stucco terraces of Holland Park and South Kensington to the mansion blocks of Kensington High Street and the more varied streets of Notting Hill and Earls Court. Beams matches you with vetted specialists suited to your project and postcode, gives you up to three like-for-like quotes to compare, and puts proper protections in place before a single day of work begins.
Every builder in the network is personally vetted. We meet them in person, check references and inspect recent work, so only reliable, high-quality tradespeople reach you. You choose who you want to work with, with the full picture in front of you.
What our Kensington builders can do
From a single room to a whole house, our builders take on the full range of home renovation work across Kensington:
Kitchen and bathroom renovations: From refits to side-return kitchen extensions.
Loft conversions: Dormer, hip-to-gable and mansard, suited to mansion blocks and period terraces.
House extensions: Single-storey and side-return to wraparound and double-storey.
Basement and cellar conversions: With proper waterproofing for below-ground work.
Full home renovations and refurbishments: First fix to final snag, under one contract.
What a builder costs in Kensington
There is no flat rate. What a builder charges in Kensington depends on the size of your property, the scope of the work, the specification and finish, and the condition of a period home. Kensington is one of London's most expensive property markets, with the Royal Borough of Kensington and Chelsea recording an average house price of around £1,233,000 in the year to July 2026 (ONS and HM Land Registry, provisional), so building work here tends to sit toward the top of the London range.
Project size | Typical estimate |
|---|---|
Lower end | £58,000 |
Most projects | £95,000 |
Larger or higher spec | £165,000 |
Top 10% of projects | £280,000 |
Based on Beams estimates for London building projects, these figures give a general guide rather than a fixed quote. A straightforward refurbishment sits at the lower end, while a large period property, a basement dig or a full back-to-brick renovation pushes it higher. Your builder confirms a fixed price once the scope is agreed, so you know the full cost before you commit.
How it works
1. Get your free estimate: Tell us about your project and budget; your planner gives you a range before any commitment.
2. Meet trusted builders: Book up to three free visits and compare like-for-like quotes.
3. Renovate with confidence: Choose your builder and Beams sets up the contract and milestone payments.
Why homeowners choose Beams over finding a builder cold
Hiring off a directory or a word-of-mouth tip is a gamble on price, quality and reliability. With Beams the hard parts are handled. You compare like-for-like quotes from vetted builders, your price is fixed in writing, your money is protected by milestone payments, and your workmanship is covered for 12 months. It is the difference between hoping a build goes well and knowing the safeguards are already in place.
Protections on every Kensington project
Every project comes with our full Protections:
Personally vetted builders: Met in person, references and recent work checked.
Fixed-price contracts: Agreed in writing before work begins.
Milestone payments: Held securely, released only when you approve each stage.
12-month workmanship warranty: Plus up to £10,000 cover if a builder leaves the network.
Licensed and insured: Minimum £6m public liability insurance.
Renovation projects across Kensington
We work with vetted builders right across Kensington, from the grand stucco-fronted terraces of Holland Park and South Kensington (W8, SW7) to the colourful streets of Notting Hill (W11), the mansion blocks around Kensington High Street, and the mixed housing stock of Earls Court (SW5) and West Kensington (W14). Our builders know the local housing stock, RBKC's planning rules and the quirks that come with renovating in this part of London.
Renovating a home in Kensington
Kensington is a patchwork of distinct pockets, and renovating well here starts with knowing which one you are in. The white stucco terraces around Holland Park and South Kensington, the grand red-brick mansion blocks near Kensington High Street, the pastel townhouses of Notting Hill, and the varied Victorian and Edwardian conversions of Earls Court and West Kensington each carry their own character and their own rules. Much of the borough sits within a conservation area: the Royal Borough of Kensington and Chelsea protects 38 separate conservation areas covering nearly three-quarters of the borough, so extensions, loft conversions and even some internal works often need full planning permission rather than permitted development.
The same design team, vetted builders and fixed-price process sit behind every project. See how our vetted builder network works, from the first design call to final sign-off.
