Highlights
“I had Darren build me a summer house using plastic brown cladding and then wood ckadding inside. I was amazed at the workmanship that went into it. The standard was far more than I expected. He was polite reliable and worked at a high standard. I was so pleased after a few months I got in contact again for him to fit my kitchen, he communicated all the way through and helped with the layout to maximise space. He also plastered my kitchen right through which was an add on. My doing !! I cannot thank him enough and will not use any other builder anymore. Highly recommended”

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.
