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.

Highlights
“I would highly recommend Alderson's - they did a fantastic job adding a doorway from our hall into the garage - it's now like the door was always there. Greg sorted any problems out that they came across and adjusted the job accordingly, bringing in necessary tradesmen as needed. He also sorted out the Building Notice for me as I had no idea how to do that.”
“Our bathroom renovation was carried out to an excellent standard. The Aldersons team were punctual, hardworking, polite, tidy, and went above and beyond to provide quality service.”
“Aldersons built a new extension housing a new kitchen from building the raft underneath my property to finishing touches they were very professional. I also used them to build 2 new shower rooms, one at the back of the garage. The work was so impressive neighbours have been asking if they can come and view it. Aldersons also kept us informed of what was to be done and when. The also gave suggestions on design etc.”

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.
