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.
