Highlights
“John and his team did a great job ( large bungalow renovation including new steels, internal wall removals, windows and doors blocked off plus major Groundworks front and back). No hesitation in recommending Pinnacle Construction. Cheers John.”
“John today finished our annexe built for my mother in our garden. I have only positive comments for the whole team - groundwork team, plasterers Alex and Ryan, Chippy Gareth, Electrician Andy and John himself who worked both as project manager and hands-on builder The whole build was well coordinated and beautifully finished. I was always involved in decision making and John went out of his way to make sure we were informed and happy. Can totally recommend Pinnacle to anyone who wants a professional builder, you won’t be disappointed.”
“We engaged John and his company Pinnacle to build a two storey extension to our existing house in 2021. Large gable end style bedroom extension and further extended our kitchen entertaining area downstairs. Professional, caring, on budget. I would highly recommend them.”

John and his team were fantastic from the first day we met. Professional, friendly and hard working- they worked to a schedule and were always approachable with any questions. We are delighted with the work completed. 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.
