“Billy and his team have just completed a single storey rear extension on my house. This is the first time I have ever done such a major renovation and I was very nervous about the whole process. Billy has been very patient with me, explaining everything that needed to happen and keeping me updated throughout. Any problems (of which there weren't many) he sorted out straightaway, including a couple of changes to the original design as the build progressed. His team work incredibly hard and I could not be happier with the end result. I would not hesitate to recommend Billy and his team.”

This trade isn't licensed in the UK, so anyone can set up. TrustMark is the only Government-endorsed quality scheme for work in and around the home - check whether they're registered, or find a TrustMark-registered business.
Check the TrustMark registerNever pay a large deposit up front. Agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow. Both are red flags for an unaccountable job.
