Beams Renovation is a London renovation company that delivers full home renovations, kitchens, bathrooms, loft conversions, extensions and basement conversions. Beams pairs every project with interior design, vetted builders and a dedicated project manager.
The main strength of Beams is structure. Most renovation problems come from unclear scopes, missing costs and poor builder selection, and Beams deals with each of these before work starts. Homeowners get a clear scope, a fixed price and milestone payments.

- Reviews: around 4.7 out of 5 from 62 Google reviews, plus more than 100 reviews on Trustpilot (checked November 2026)
- Services: full home renovation, kitchens, bathrooms, loft conversions, extensions, basement conversions, interior design
- Worth knowing: It is not the cheapest route for a small cosmetic job, and a few reviews mention delays on individual projects.
2. houseUP: Complete house refurbishment
houseUP specialises in substantial refurbishments, especially where the existing layout needs major changes. Reviewers mention in-house structural engineering and careful work on listed and conservation area flats.
- Best for: complete house refurbishment
- Address: 71-75 Shelton Street, London WC2H 9JQ
- Reviews: 5.0 out of 5 from 10 Google reviews (checked November 2026)
- Worth knowing: It has a small number of public reviews, so there is less evidence to judge it on.
3. Proficiency Design & Build: Large structural projects
Proficiency Design & Build handles refurbishments, extensions, basements and loft conversions, so it suits complex structural work more than a light refresh.
- Best for: large structural projects
- Address: 31 Fortune Green Road, London NW6 1DU
- Reviews: around 4.8 out of 5 from 43 Google reviews (checked November 2026)
- Worth knowing: It is geared to major building work and is more than a single-room project needs.
4. London Renovation Company: Traditional full-service renovation
London Renovation Company covers architecture, structural engineering, interior design and general construction, so one contractor takes responsibility for most of the project.
Worth knowing: Its public review count is low, so ask for recent references.
5. Plus Rooms: Extensions and side returns
Plus Rooms has a clear specialism: rear extensions, side returns and loft conversions, with in-house architects and a fixed price model that reviewers often mention.
Worth knowing: It is an extension specialist, so it is a weaker fit for an internal renovation with no added space.
6. NU Projects: High-end architecture and design
NU Projects combines architecture, design and construction and suits higher-value London homes, with reviews mentioning projects in Belgravia and West London.
Worth knowing: It is aimed at larger budgets and is likely to be more than a standard renovation needs.
