Most “best renovation company” lists are thinly disguised adverts, so we set out to write the opposite: an honest, independently researched review of the best home renovation companies in London.
No company paid to appear here. This ranking is the result of our own in-depth research into design capability, service range, pricing, protections, and published customer reviews.
For each of the seven companies below we read reviews across sources such as Trustpilot and Google, studied completed projects and portfolios, and checked how pricing, contracts, and payments are handled. Where a claim came from a company rather than an independent source, we say so.
Beams ranks first, and is the best home renovation company in London for kitchens and bathrooms, thanks to in-house bespoke design, vetted builders, fixed pricing, and secured milestone payments.

How we researched this review
This is an independent review, not a directory listing. Every entry reflects our own assessment rather than a sales pitch.
We read published customer reviews for each company, studied their completed renovation projects, and looked closely at how each one handles design, pricing, contracts, and payment protection.
We then weighted the things that actually protect a homeowner during a renovation: vetted trades, fixed pricing, secured milestone payments, and workmanship warranties.
We also favoured end-to-end delivery, because the smoothest home renovations keep design, building, and payment handling under one accountable process rather than spread across separate parties.
1. Beams: best for kitchens and bathrooms
Beams is the best home renovation company in London for kitchens and bathrooms, and our top pick overall for homeowners who want the whole project designed, built, and protected in one place.
On kitchens, Beams designs bespoke ranges in-house and crafts them with vetted London joiners, letting you configure every cabinet to your space and see the result in 3D before a single unit is fitted. On bathrooms, it delivers a full refurbishment from top to bottom, built to last and designed to feel calm, with the design and the builders handled for you.
Beams also covers loft conversions, extensions, and full home renovations across North, South, East, and West London, giving you one builder, one contract, and one point of contact from first design to final coat of paint.
Every builder is personally vetted, visited in person, reference-checked, and inspected on recent work, with an average of 15 years of residential renovation experience. You meet up to three vetted builders and compare detailed, like-for-like quotes before you commit.
The protections are what set Beams apart. Prices are locked in upfront in writing, milestone payments are held securely and released only when you sign off each stage, and every builder warrants their workmanship for 12 months, with Beams stepping in with up to £10,000 of cover if a builder leaves the network during that period.
Beams is a certified B Corp and has been featured in the Financial Times, The Times, The Telegraph, The Guardian, Elle, and House & Garden, and its customer reviews consistently describe a calm, well-managed process. For kitchens and bathrooms especially, Beams sets the standard the rest of this list is measured against.
2. NU Projects: best architectural design-and-build
NU Projects is a strong choice for homeowners who want architecture, interior design, and construction delivered by one leadership team.
The British-led design-and-build studio focuses on high-value residential renovations with full control from concept to completion, using in-house architects and specialist trades.
It suits larger, design-led projects where a single accountable team from drawings to build is the priority.
3. houseUP: best for prime full-house refurbishments
houseUP focuses on complete house renovations, layout reconfiguration, and high-end finishes.
The company reports experience in prime areas such as Belgravia, Highgate, and Kensington, which points to comfort with period properties and demanding specifications.
Its services are best suited to full-house refurbishments in central and prime London postcodes.
4. APT Renovation: best for luxury extensions and basements
APT Renovation specialises in luxury home building and comprehensive house renovations across London.
Its services span kitchen extensions, basement conversions, full refurbishments, and new builds, aimed at homeowners investing in a substantial transformation.
APT is a sensible shortlist option when the brief centres on adding space through an extension or basement.
5. Hill & Way: best for bespoke high-end craftsmanship
Hill & Way positions itself as a high-end residential contractor serving Kensington, Chelsea, and Hampstead.
The firm emphasises bespoke craftsmanship and hands-on project management for luxury refurbishments.
Homeowners in prime South West and North West London who value detailed finishing will find it a relevant option.
6. LCCL Construction: best for extensions and loft conversions
LCCL Construction concentrates on house extensions, loft conversions, home renovations, and new builds.
The company reports more than 20 years of experience and strong review scores, and says it won a LABC Building Excellence Award for a residential extension in London in 2024.
It is a solid pick when your project centres on adding space through an extension or loft.
7. DPA Home Renovations: best family-run all-rounder
DPA Home Renovations is a family-run construction company handling full house renovations, kitchen extensions, lofts, basements, and new builds.
With more than 20 years of experience, it offers broad coverage across common London renovation project types.
Homeowners who prefer a hands-on, family-run team may find it a comfortable fit.
What makes the best home renovation company in London?
The best home renovation company in London removes the three biggest sources of stress: money, timing, and trust.
Look for personally vetted builders, fixed-price contracts agreed in writing, secured milestone payments released on your sign-off, and a workmanship warranty that survives after the builders leave.
In-house interior design with 3D visualisation is a strong signal too, especially for kitchens and bathrooms, because seeing the space before work starts prevents costly changes mid-build.
Beams brings all of these together, which is why it leads this honest review of London home renovation companies.
