Tiling- 6 Jun 2026
Thief!!! Don’t hire him,he’s a crook!! He takes advantage of people who don’t know much about building(always he want to buy everything for you and steal at the end) Don’t fall for his first appearance. I’ve requested for receipt of things he bought for me,more than 3weeks and he hasn’t been able to provide it(he took almost the rest of the things he bought for me to his house ) I’ve again requested for the quote we all agreed on(which he wrote in his diary)same he hasn’t been able to provide it. I bought turbo drive screws(500 qualities) from trade point,he used less than 15 screws and took the rest to his house. Have a lot to say but I will meet him in court.

Extensions- 29 Jun 2022
Dan and his team offered a very competitive quote and a prompt reply. He was polite and respectful, worked hard and tidied up at the end of the build. The work was carried out to the highest of standards and I am more than delighted with the finished product. I would not hesitate to recommend him to my friends and relations and would certainly contact him again for any work I may have.

I think Anthony is best described as he and his staff take pride in their work. I had a new block-paved drive done. All way through he advised me on the best options and ideas I would not have thought of such as ensuring that any rainwater took the best path towards drains rather than merely ending up in the garden. I would thoroughly recommend Hennerleys for work.

Extensions- 15 Dec 2022
Recently had an extension undertaken by C&C. I put the feelers out for contractors and they were fast in quoting and managed to squeeze me. I'd had massive issues with my previous contractor so I was a bit wary at 1st but the lads were spot on. Kept in constant contact, updated me on any issues, worked with me on any changes that needed to be made and did what they said they would, at a very fair price. The lads took ownership of contacting building control, grabbing materials where required and also drafted in additional help or trades when needed. Even after completion the lads have said they will come back and do any snags required if I spot anything. Can't recommend them enough.
