At a glance

1. Beams Renovation: Best overall for home renovation

Beams Renovation is a managed renovation service for London homeowners. It brings interior design, builder selection, contracts and construction support into one process, with a showroom on Hanbury Street in East London.

Beams stands out because homeowners do not have to find a designer, a builder and suppliers separately. Builders are vetted, quotes are based on a clear scope, and a project manager checks progress on site.

• 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. 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.

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. 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.

Worth knowing: It has a small number of public reviews, so there is less evidence to judge it on.

5. 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.
