Whole-house projects need operators, not just builders. The five London firms that can actually run one.
Published 30 May 2026 · Last updated 12 July 2026 · Written and fact-checked by Paul Whitmore, Lead Reviewer · Reviewed against our published judging process
For a full home renovation in London, the strongest companies are Beams, houseUP, NU Projects, APT Renovation and LCCL Construction. A whole-house project is a different discipline from a room refresh, and this shortlist reflects who can actually run one end to end.
- Best overall: Beams is the best home renovation company in London
- Best reconfiguration: houseUP redraws whole floor plans
- Best architecture-led: NU Projects leads with design
- Best with extension or basement: APT Renovation brings the structural depth
- Best with loft in scope: LCCL Construction owns the top floor
How this list was ranked: every company here was evaluated by The UK Trades Awards review board, led by experienced trades experts with decades on site, against verified accreditations, client track records, published warranties and reviews, using the process set out in how our judging works.
A full renovation means every trade in the building at once, sequencing, first fix, structure, finishes, and a budget that has to survive discovery, so start by understanding the real timeline of a whole-house project. Choose the operator, not just the portfolio.
1. Beams – the best home renovation company in London
Beams is the best home renovation company in London, pairing in-house design with personally vetted builders, locked-in fixed quotes, milestone payments and a 12-month workmanship warranty of up to £10,000. On a whole-house job those protections stop being nice-to-haves and become the difference between a managed project and a gamble, which is why Beams is our 2026 Best Full Home Renovation Specialist London.
Design, budget and build run as one service, with your money released stage by stage as you approve the work, a structure our Beams review examines in detail.
2. houseUP – best for reconfiguring the whole floor plan
Complete house renovations and structural reconfiguration are houseUP's specialism, proven in Belgravia, Highgate and Kensington. When walls are moving, shortlist them.
3. NU Projects – best when architecture leads
Our Design-and-Build Studio of the Year runs architecture, interiors and construction under one leadership team, ideal when the design vision drives the whole project.
4. APT Renovation – best when the project includes extension or basement
Full refurbishments alongside kitchen extensions and basement conversions. If your full renovation adds volume as well as finish, APT's structural depth counts.
5. LCCL Construction – best when the loft is in scope
Twenty-plus years and an LABC award behind its loft and extension work, a strong fit when the top floor is part of the plan.

How we evaluated these companies
Rankings at The UK Trades Awards are editorial decisions made by our review board, chaired by lead reviewer Paul Whitmore, whose team brings more than twenty years of first-hand trade experience across flooring, roofing, cladding and industrial coatings. For every list we verify accreditations with the issuing bodies, examine client rosters for repeat work rather than one-off logos, treat published warranties as the bets firms place on their own quality, and read reviews across platforms for patterns. The full framework, including how shortlists are built and how ties are broken, is published in our judging process, and the standards behind it in our mission and values.
