Renovation Lambeth: Matched Quotes from Vetted Builders
Kitchen renovations, bathroom refits, loft conversions, house extensions and full house refurbishments across Brixton, Clapham, Stockwell, Streatham, Herne Hill and every other part of the borough, all with no cold calls.
What are you renovating?
Lambeth is one of London’s most active renovation boroughs. It is also one of the most varied. A Victorian terraced house in Brixton sits on different planning ground to a purpose-built flat in Vauxhall or a semi-detached house in Streatham. The builder who knows that difference, who has worked in your street, who understands what Lambeth Council’s planning department expects, and who has dealt with the borough’s conservation area constraints is not always the builder who sends the first quote.
QuoteMyRenovation matches Lambeth homeowners with up to three vetted builders who have recent, verifiable project history in their neighbourhood and for their renovation type. One brief, three matched quotes, no cold calls.
A Story from Tulse Hill
In the summer of 2025, the owners of a mid-terraced Victorian house on Tulse Hill received three quotes for a rear kitchen extension and full kitchen renovation. The first came in at £48,000, a one-page summary with no structural specification and no mention of Party Wall notices. The second was £61,500 and included the structural engineer’s fee, Party Wall Act notices for both adjoining owners, planning pre-application advice, full building regulations drawings, and a named kitchen manufacturer with a supply contract. The third came in at £54,000 and, on reading it carefully, excluded the Party Wall Act costs and the structural engineer’s fee entirely.
The homeowners chose the £61,500 quote. On a job like this, in a borough where both adjoining neighbours are entitled to appoint their own Party Wall surveyor at the Builder’s cost, understanding what the quote does and does not include is the difference between a budget and a final bill.
Renovation in Lambeth: What Makes This Borough Different
The Housing Stock
The majority of owner-occupied houses in Lambeth are Victorian or Edwardian terraces, two-up two-down and larger, built between approximately 1870 and 1910. They are concentrated in Brixton, Stockwell, Clapham, Tulse Hill, Herne Hill, West Norwood, and the streets between them. Most have back additions: the single-storey or two-storey rear outriggers that define the South London Victorian terrace plan. This configuration creates excellent potential for rear extensions, wraparound extensions, and L-shaped loft conversions, but it also creates constraints that builders unfamiliar with Lambeth’s stock may not price accurately.
Lambeth has over 60 designated conservation areas. Clapham Old Town, Stockwell, Brixton Market, Poets Corner, Herne Hill, Streatham Hill and many others impose restrictions on the appearance and materials of any works visible from the street, including rear dormers, roof alterations, and replacement windows. Permitted Development rights are modified or removed entirely within conservation areas and on Article 4 Direction properties. A builder who does not check the planning position before quoting is pricing a different job to the one that will actually be built.
Party Wall Act
Lambeth terraces sit tightly together. Almost every rear extension, loft conversion or basement project will require Party Wall Act notices to be served on one or both adjoining owners. If an adjoining owner dissents, both parties must appoint (or share) a party wall surveyor, and a Party Wall Award must be in place before notifiable works begin. This adds cost, typically £800 to £2,500 per adjoining owner and time. Any quote for a Lambeth renovation that does not mention the Party Wall Act has not accounted for a significant part of the process.
Lambeth’s Victorian terraces often have kitchens at the back of the ground floor, separated from the reception rooms by a hallway and a load-bearing wall. Opening up the ground floor by removing the wall, reconfiguring the layout, and often extending into the rear garden is the most requested kitchen renovation in the borough. Costs for a kitchen renovation with rear extension in Lambeth typically range from £45,000 to £95,000 depending on the extension size and kitchen specification. A like-for-like kitchen refit without structural work costs £12,000 to £35,000.
Full bathroom refits in Lambeth range from £7,000 to £22,000 for a standard room. En-suite additions within existing bedroom space are particularly common in the larger Victorian terraces of Brixton, Herne Hill and Clapham, where a spare bedroom can often accommodate a 4–6 m² shower room without planning permission. In flats, Lambeth has a high proportion of converted flats; freeholder consent is almost always required before any works begin.
The L-shaped dormer loft conversion is the predominant type in Lambeth, because the Victorian back addition creates the second dormer that makes the L-shaped configuration possible. This adds 30 to 50 m² of usable floor area to a typical Lambeth terrace and typically costs £60,000 to £95,000. Conservation area properties may be restricted to mansard or rooflight conversions depending on their position relative to the street and the borough’s conservation area appraisal. A rear dormer is the most common non-conservation option, costing £45,000 to £85,000.
Single-storey rear extensions are the most common extension type in Lambeth. Under the Prior Approval (Larger Home Extension) permitted development route, detached houses can extend up to 8 metres and terraced or semi-detached houses up to 6 metres without full planning permission, subject to a 42-day neighbour consultation. In conservation areas, this route may not be available, and full planning permission is required. Costs for a single-storey rear extension in Lambeth range from £35,000 to £75,000 depending on size and specification. Two-storey rear extensions cost £60,000 to £120,000.
A full house refurbishment in Lambeth, structural reconfiguration, new kitchen, new bathroom, redecoration throughout, and a new heating system typically costs £80,000 to £200,000 on a standard Victorian terrace. Period features (cornicing, ceiling roses, sash windows, fireplaces) add both cost and complexity. Many Lambeth homeowners undertake a full refurbishment when purchasing a property that has been converted to flats and is being returned to single-dwelling use, a project that requires planning permission and often listed building or conservation area consent.

Excludes structural engineer fees (typically £600–£1,500), Party Wall surveyor costs (£800–£2,500 per adjoining owner), architect fees, and planning application fees. Conservation area properties should allow an additional 15–20% for compliance costs. Add 10–15% contingency on all projects.
Finding the Right Builder in Lambeth
Not every builder who works in London is equipped to work well in Lambeth. The right builder for a Victorian terrace kitchen extension in Herne Hill needs: experience with load-bearing rear wall removal and steel specification in Victorian buildings; familiarity with Lambeth Council’s planning officers and their approach to conservation area applications; knowledge of the Party Wall Act process in a dense terrace context; and a track record of managing work in occupied properties without excessive disruption.
Before appointing any builder in Lambeth:
- Ask for references from projects of the same type completed in the borough in the last 18 months — and call them
- Confirm public liability insurance of at least £2 million
- Ask whether the quote includes or excludes the structural engineer’s fee, Party Wall Act costs, and planning fees
- In a flat, confirm that freeholder consent is in hand before any quote is accepted
- Agree a payment schedule tied to defined stages, not calendar dates
