Public evidence profile
How this score is made up
Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.
Each card sums up one thing we can check from public sources. Open it for the full detail and the named source. This is evidence context, not a guarantee.
These credentials and memberships are attributed to named public sources. Check the source before relying on them.
What this protects you with: As a member of the Federation of Master Builders, you get independent vetting of the builder, the option of an insurance-backed warranty on the work and access to a dispute resolution service.

Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer.

“STL have done a fantastic job building my new summer house from the ground works including concrete slab to the timber frame and roof and making it water tight I will be getting them back to install all the external cladding.”
“Simon is highly knowledgeable in the extension and refurbishment sector. Worked alongside him on many jobs and he runs the jobs efficiently and too the budget”
“I found Simon at STL Ltd very helpful and professional throughout the works. At all stages he would let us know what was being completed and how long it would take. Apart from some extras we requested, everything was as per the quote. Would definitely recommend him. Regards, Keith.”
He's a very friendly, reliable tradesman - have news him a few times.
Simon and his team completed our house extension and I couldn’t be happier with the result. From the start he was clear on scope, timings and communication throughout was excellent. They were punctual, respectful of our home, and kept the site as tidy and safe as possible day to day. The quality of workmanship is really a high standard, well-finished, and properly thought through. Any questions or small changes along the way were handled professionally, with options explained with better solutions instead of our architect. I would happily recommend them and would use them again.
Simon and his tradesmen did a fabulous job. The project was completed on time, to a very high standard. Attention to detail was excellent. Would highly recommend.
