S&J Developments are an amazing company, I have used them 3 times now. On this 3rd job they installed new kitchen cupboards for me. They came in on time and they installed it before end of day. I'm very happy with their service and they even got draws installed that didn't come with what we bought ahead of time. They are an amazing company and would highly recommend.

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 register
Never 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.
