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.

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. Around 9 years on the register also points to an established business rather than a brand-new one.

Highlights
“Firstly to say this work was carried out last Summer so have been late in submitting but needed to recommend. Ross and his team have carried out damp work in our old house on a number of occasions and their work has always been first class. We contacted Ross in about March 2025 for some damp work in our kitchen, this lead to far more work than anticipated. Throughout the whole process we were kept informed of timescales and additioanl cost associated with unfortunately finding cracks in the exterior of the walls which we had been forewarned about may happen after the rendering was removed.”

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.
