Conversions - General- 30 Jan 2019
We recommend Paul highly and will definitely employ him again. Paul is highly skilled at what he does and he is very committed to the quality of his work. He ensures everything is done to a very high standard. He quotes accurately and his costs are reasonable. The breaking down and finishing of the wall between our kitchen and dining room makes our home looks great! He has good suggestions which we did not think about and which enhances the effect. We are really delighted with the quality, the speed and the aesthetics of the work that Paul has done for us. We will be asking Paul to come in to work on many other refurbishments to our home.

Extensions- 31 Jan 2026
Dominic and his team took on my large extension, which consisted of a 2 storey side extension and a full width single storey rear extension. The ground works were very complex but the team handled it with ease and tackled everything that was thrown at them. They arrived early each day and if the weather and light light permitted they regularly left late, but would always ask if it was ok to ‘work on’, they even worked a few weekends and bank holidays. Anyhow I couldn’t recommend Kingdom Renovations enough, you won’t be disappointed. 5⭐️

Extensions- 15 Dec 2024
Fantastic company!!! From start to finish, Philip and his team have been friendly, polite and are clearly very experienced experts at what they do. Excellent industry knowledge enabled them to navigate some unforeseen complications with minimal fuss and cost. Finding a builder can be a very stressful process, as there’s a lot of choice and it’s probably the second biggest investment you’ll make, only second to the actual house itself. They’ve been absolutely brilliant, with almost daily updates on their progress and plans for what they’re going to do next. Made us feel very confident in allowing them to do what they do best without a single worry. Another thing to mention is the sheer speed at which these guys get the job done. Philip makes sure that he throws as many skilled men as he can at each stage of the build to ensure that it’s competed without delay. Does pouring the foundations on the second day on site sound like a great achievement?? It certainly does to me! Would recommend to anyone. Pick these guys, you’ll be glad that you did!

I am very pleased with the quality of work Gordon completed on my composite decking. He was here for three days and worked tirelessly through a very rainy afternoon. I found his communication to be excellent, keeping me up to date on materials ordered and a timescale for work to be completed. Professional, honest and friendly. I’d definitely recommend him to friends and family.
