How the companies compare

1. Beams Renovation: Best overall for home renovation

Beams Renovation manages home renovations across London from design to completion. Its service covers 3D design, vetted builders, fixed-price quotes and project management, for anything from one kitchen to a whole house.

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.

• Best for: full house and flat renovations, period homes and multi-room projects, first-time renovators and homeowners without a trusted builder
• Address: 17 Hanbury Street, London E1 6QR
• 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. 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.

• Best for: extensions and side returns
• Address: Unit 30, NW Works, 135 Salusbury Road, London NW6 6RJ
• Reviews: around 4.9 out of 5 from 388 Google reviews (checked November 2026)
• Worth knowing: It is an extension specialist, so it is a weaker fit for an internal renovation with no added space.

4. 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.

5. 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.

6. 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.

Worth knowing: It is geared to major building work and is more than a single-room project needs.

7. NOVA Design & Build: Premium design and build

NOVA Design & Build works on major refurbishments and extensions and combines design, construction and project management.

Worth knowing: Better suited to high-specification projects than modest budgets.
