How We Reviewed
Build Quality and Craftsmanship: We looked at completed builds to see how well the finishes hold up after the crew leaves. A great builder pays attention to structural integrity and tiny details like clean joinery and smooth plastering.
Pricing Transparency: Nobody likes surprise bills halfway through a build, so we favoured firms that give clear written breakdowns for labour and materials. You should know what you’re paying for before a single brick gets laid.
Project Management and Communication: Construction projects have a lot of moving parts, and poor communication causes delays. We picked companies that keep you in the loop from beginning to end.
Versatility and Trade Skills: Your contractor needs a deep bench of qualified tradespeople. We checked that each team had the right licences, insurance, and specialised skills for complex London plots.
1. Design and Build London Renovation Ltd
Website: https://designandbuildlondon.com/
Address: 155 Munster Rd
Contact: 0203 3725 366
Hours: Monday to Friday, 8 AM – 5 PM
Design and Build London Renovation Ltd stands out because they’re an all-in-one company. These folks will develop your architectural plans, structural work, and custom woodworking.
They handle ground-up custom homes, loft conversions, fibreglass roofing, and bespoke joinery. They even design features for seamless indoor-outdoor garden integration, connecting the main living area to the private courtyard.
If you need heavy structural work, their qualified tradesmen keep the finish quality high. To boot, their expertise comes at a fair price.
We appreciate that they take on both commercial and residential developments across Greater London. But because they cover such a huge territory and juggle business clients, booking a slot during peak summer construction months can get tricky.
Customer Reviews

I will definitely work with them again at the next opportunity
Whenever anyone asked me how was the renovations were going in the new flat I bought, I said that I have the perfect contractor. B&D are incredibly reliable and work quickly. They updated me throughout this process with photos and I felt like my flat was in safe hands. Renis went above and beyond to make me happy and make sure I got what I wanted. I will definitely work with them again at the next opportunity and high-highly recommend them!!

2. Rafixbuilding Ltd
Website: https://www.rafixbuildinglocalbuilderlondon.co.uk/
Address: 9B Fordham Cl
Contact: 07872 967015
Hours: Monday to Sunday, 7 AM – 10 PM
Rafixbuilding Ltd stands out for their hands-on guidance, which starts with thorough on-site consultations. They don’t just hand you a generic quote; they look at your layout and give practical recommendations that fit your budget.
Service-wise, they focus on tailored residential renovations, kitchen and bathroom upgrades, and general building work. Their carpenters and plasterers are fantastic at custom wardrobes, crisp wall finishing, and exterior decorating.
We highly appreciate their seven-day availability from early morning until late evening, making it super easy to reach them if an urgent question pops up after work.
However, they aren’t the right fit for everyone. Their sweet spot is transforming existing houses rather than building brand-new properties from scratch.
Customer Reviews

3. Right Build Group
Website: https://www.rightbuildgroup.co.uk/
Address: Westbourne Park Road
Contact: 020 3404 2271
Hours: Monday to Friday, 9 AM – 6 PM
Based near Westbourne Park, Right Build Group tackles complex property refurbishments, garage and loft conversions, and structural house extensions.
They’re a flexible contractor, offering water damage restoration alongside standard carpentry and flooring. This expertise is a lifesaver if you’re renovating an older Victorian terrace with hidden damp issues.
It’s a massive advantage that they provide upfront costs to make budgeting much less stressful. Their team delivers written quotes within three to five working days, complete with a clear breakdown of labour and material costs.
On the flip side, their office closes on weekends, so you’ll have to handle all your planning meetings during the workweek.
Customer Reviews
Project delivery was excellent
We needed urgent renovation work carried out in our home, and I was dreading the thought of dealing with difficult and dishonest builders. However, Right Build Group smashed the stereotype perception of builders. They were so professional from beginning to end, and every stage was handled well. Communication was flawless. Costs were reasonable. Project delivery was excellent.

Couldn’t recommend more highly
We’ve had an amazing experience working with Right Build. We worked with John, Duncan, Zak and Gunai to conduct comprehensive renovations to our flat while we were still living in it. Their level of professionalism and high standards are exactly what you look for in builders. They are considerate, responsive, thorough and honest people and are very pleasant to work with. Couldn’t recommend more highly.

4. NWL Builders Ltd
Website: https://nwlbuilding.com/
Address: 22 Belsize Square, London, NW3 4HT
Contact: 020 7126 8289
Hours: Monday to Saturday, 8 AM – 7 PM
NWL Builders Ltd specialises in bespoke new developments and large-scale residential or commercial builds. They manage the entire lifecycle of your build, guiding you from the initial architectural design right through to the final walk-through.
Their crew is closely involved at every stage. They even handle planning permissions, ensuring each phase of your project complies with London’s strict building regulations and local council guidelines.
Transparency is important here too, as they give you detailed cost estimates upfront so you get solid value for your money.
But their high-touch, custom process takes time. If you want a quick, cookie-cutter build, their process might feel too slow.
Customer Reviews
I won’t be using anyone else but NWL Builders for all my future projects
I had NWL Builders led by Volodymyr do a full renovation and redesign of my new flat in Chelsea, and I’m really happy with the results! They turned my place into a beautiful high-end space. The team was friendly and worked hard, and the prices were ok. If you need renovation work, I would definitely suggest NWL Builders!. I won’t be using anyone else but NWL Builders for all my future projects.

I’m thrilled with my new space and would recommend NWL Builders
We hired NWL, for some house structural changes and a full renovation of my property in Central London. The transformation they achieved was fully satisfactory. Volodymyr and his team were professional and attentive. They are bit pricey but completed the project in a timely manner. I’m thrilled with my new space and would recommend NWL Builders.

5. Made Construction Simple
Website: https://www.madeconstructionsimple.co.uk/
Address: 20-22 Wenlock Road
Contact: 020 3603 6438
Hours: Monday to Friday, 8 AM – 8 PM; Saturday, 9 AM – 7 PM; Sunday, 9 AM – 8 PM
Made Construction Simple is backed by over four decades of combined industry experience. This licenced and insured team is a powerhouse for homeowners planning single-storey, double-storey, or even triple-storey house extensions.
If you want to renovate your home, their team can handle full kitchen and bathroom refurbishments. They also knock out loft conversions for extra bedrooms or home offices.
Plus, their carpentry, flooring, and decorating crews work together smoothly, so you don’t have to babysit the site.
Their availability deserves a mention, as they have an average response time of just one hour for free project cost estimates. And because they’re open late most nights, including Sundays, getting hold of a project manager is a breeze.
The thing is, they aren’t the cheapest builder in the area, so if you’re working with a tight budget, their premium service may not be the right fit.
Customer Reviews
They did an excellent job!
Brayan and his team completed a full property renovation for me, from start to finish. The entire place was stripped back and rebuilt using high-quality materials, and the results speak for themselves. They did an excellent job! The kitchen looks amazing, and the bathroom has been beautifully finished. Brayan is a highly skilled builder who clearly works with a solid and reliable team.
