Complete house renovation from top to bottom. Edmond was very knowledgeable, professional and most importantly honest. He really cared about his work - he’s a perfectionist! He completed the work on time and after 5 years of renovation it still looks like the day he built it! Extremely happy with his work. He was clean and tidy too!

N5.0 / 5

I had my house fully refurbished and I’m really pleased with the results. The job included stripping out the old bathroom, kitchen, flooring, electrics and boiler, and replacing everything new. The finish is excellent and the quality of work is clear in every room. What I really liked was how reliable and hardworking Edmond and his team were, throughout. He kept me updated, turned up when he said he would, and always made sure things were done properly. You can tell he takes pride in his work, and nothing felt rushed or cut short. He’s not the cheapest builder out there, but the standard of work and peace of mind you get makes it well worth it. I’d happily recommend him to anyone looking for a builder who gets the job done to a high standard. This is the second time we've worked with BLS, who we have also recommended to other family members who have also been very happy with his standard of work.

BLS Builders are excellent. I have worked with them over them on multiple projects at my house over the last 10 years, including full renovation and extensions, garden landscaping, drive way and many more projects. The BLS team are absolutely dedicated to you and your family and your house project. They are a trusted advisor and exceptional at every project I have asked them to carry out. They are utterly dependable, they really listen and work with you and take the time to understand you and your project. I have very high design standards and the team have worked with me on the projects to achieve my vision. I highly recommend BLS and trust their advice and their commitment to deliver exceptional work every time. In addition the team follow up and are always available to help in the future if I need them. Totally dependable and good value for money. Very happy to recommend BLS Builders.

BLS returned to fit a new internal door after they had completed a two storey side extension with a loft conversion with a complete new roof. They installed an ensuite wet room with underfloor heating. They also fitted a new hot water storage tank and water softener, knocked through from old to new and made good. We had new fire doors fitted throughout and linked fire and CO alarm system. They also refinished the complete exterior facade, and now we often get comments from people passing the house about how lovely it looks. I have no hesitation recommending BLS.

We hired BLS for a full home renovation including a loft conversion, rear extension, and kitchen renovation. From start to finish, their work was exceptional. The loft was built to a very high standard, adding a bright, spacious bedroom and bathroom. The rear extension has completely opened up our ground floor, and the new kitchen has been fitted beautifully , every detail was carefully handled, from plumbing and electrics to finishing touches. The BLS team were professional, tidy, and always respectful of our home. They stuck to the agreed timeline and budget, kept us updated throughout, and were always happy to answer questions or offer advice. We’re thrilled with the final result and would highly recommend BLS to anyone looking for reliable, skilled, and hardworking builders.

We recently had an extension built and the whole process was absolutely seamless. The team worked like Swiss clockwork – everything was perfectly organised, on time, and to an excellent standard. Communication was clear throughout, they kept the site tidy, and every detail was finished to a very high quality. Reliable, professional, and trustworthy – exactly what you hope for when undertaking a big project like this. I wouldn’t hesitate to recommend them to anyone looking for building work.

Build of garden outhouse, front porch, repositon and installation of system boiler with mega flow. Installation of radiators, renovation of downstairs cloakroom, garden landscape and patio. Highly professional. The project had several different asks and skill sets required all of which was met to the highest standard. The team were prompt, hard working, clean and diligent. The project was agile with many moving parts. BLS were very flexible to help accommodate new asks and help come solutionize issues as and when they appeared. I felt confident I had the right people for the job and full trust in their ability. Minor touch ups were left and a very small snag list which was handled swiftly too. Edmond prides his work and ensure its done to the highest standard which includes purchasing quality material for robust build. Can't fault them and happy to refer them to anyone who wants a hassle free build

We were really pleased with Edmund and his team’s work on our bathroom. He was friendly and professional. One thing that stood out was his attention to detail. He made sure that the tiles matched up perfectly and was a perfectionist with his work. When they left, they left the hallways and stairs cleaner than before they had arrived! Edmund had been recommended to us by a friend who works in the building business who has worked with him, so from the start we were confident that he would do a good job. We are so pleased with our bathroom!

The work was seamless—like magic! While we were away, everything was done perfectly. They replaced the ceiling so flawlessly that, if it weren’t for a tiny bit of dust on the glass, we wouldn’t have even known they’d been there. No cracks, no signs—just flawless work. Cannot recommend enough

Before you hire an architect

Only someone on the Architects Registration Board (ARB) register may legally call themselves an 'architect' in the UK — ask for their ARB number and check it free at arb.org.uk. An 'architectural designer' or 'technologist' is a different, unregistered role (often capable, but not the same protection).
Agree how they charge before any work starts — a percentage of the build cost, a fixed fee, or an hourly rate — and exactly which stages it covers (concept design, planning application, building-regulations drawings, work on site), so there are no surprises later.
Confirm what they will actually handle versus what is excluded — the planning application, the building-control drawings, and whether they will administer the builder's contract on site — and get it, and a portfolio of similar projects, in writing.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
