1. Beams Renovation: Best overall for full flat and house 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. 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. 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.

  • Best for: traditional full-service renovation
  • Address: Coniston Court, Kendal Street, London W2 2AN
  • Reviews: 5.0 out of 5 from 8 Google reviews (checked November 2026)
  • Worth knowing: Its public review count is low, so ask for recent references.

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. 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.
