Builders in Lambeth

Beams connects homeowners in Lambeth with personally vetted, insured builders for kitchen and bathroom renovations, loft conversions, extensions and full home refurbishments, whether you own a period property or a more modern home.

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.

Vetted builders in Lambeth, not one-size-fits-all

Most searches for a builder in Lambeth end with one quote from one firm and a leap of faith. Beams works differently. We match you with vetted specialists suited to your project, give you up to three like-for-like quotes to compare, and put 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 Lambeth builders can do

From a single room to a whole house, our builders take on the full range of home renovation work across Lambeth:

Kitchen and bathroom renovations: From refits to side-return kitchen extensions.

Loft conversions: Dormer, hip-to-gable and Velux.

House extensions: Single-storey and side-return to wraparound and double-storey.

Basement and cellar conversions: With proper waterproofing.

Full home renovations and refurbishments: First fix to final snag, under one contract.

What a builder costs in Lambeth

There is no flat rate. What a builder charges in Lambeth depends on the size of your property, the scope of the work, the specification and finish, and whether you are renovating a period conversion or a newer home near Vauxhall or Waterloo. Rather than quote a headline figure, Beams gives you a free estimate range upfront, and your builder confirms a fixed price once the scope is agreed, so you know the full cost before you commit.

Based on Beams estimates for London building projects, here is a general guide to what homeowners pay:

Project type

Typical estimate

Lower end

£15,000

Most projects

£35,000

Larger or higher spec

£65,000

Top 10% of projects

£120,000

These are estimate ranges rather than fixed quotes. A single-room refurbishment sits well below the lower figure, while a full house renovation or extension pushes it higher. Your builder confirms a fixed price once the scope is agreed, before any work begins.

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 Lambeth 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 Lambeth

We work with vetted builders right across Lambeth, from Waterloo and Kennington through Vauxhall and Stockwell to Brixton and Clapham, as well as Streatham, the borough's other core neighbourhood, which has its own dedicated Beams pages. Our builders know the mix of Georgian terraces, Victorian villas, mansion blocks and newer riverside development that makes up Lambeth, along with the council's planning rules and conservation area requirements.

Renovating a home in Lambeth

Lambeth runs from Waterloo and the South Bank through Kennington and Vauxhall to Stockwell, Brixton and Clapham, with Streatham forming the borough's southern reach and covered by its own dedicated Beams pages. The building stock is varied: Georgian terraces around Kennington, grand Victorian villas in Clapham, mansion blocks near Brixton, and a good deal of post-war and newer development around Vauxhall and Waterloo. Lambeth has more than 60 conservation areas, including Kennington, Albert Square, Clapham Old Town and Vauxhall, so extensions and other external changes on period streets often need full planning permission from the council rather than permitted development.

With the average Lambeth home selling for around £537,000 in the year to July 2026 (ONS/HM Land Registry, provisional), getting a build right matters. Our vetted builders cover Lambeth's neighbourhoods and the nearby boroughs of Southwark and Wandsworth, from a single room to a full refurbishment.

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.
