UKPC Construction is by far the best company I have ever worked with, and I highly recommend them to anyone. Their team is not only courteous and professional but also a breeze to work with. They expertly helped me transform my jungle-like garden, and although I'm writing this review after some time, I'm now looking forward to discussing the extension project they initially designed with me. A big thank you to UKPCC, and I wholeheartedly endorse their services to everyone.

Landscaping- 17 Mar 2020
WOW!!!! Having previously being ripped off when having my patio laid and having to suffer increasing frustration and disappointment with it for over 9 years or so I finally caved in and looked to have it redone. Keith was a revelation. He listened to my tale of woe and asked pertinent and intelligent questions to understand what I actually wanted when he came to do the survey. The quote he produced was quick, detailed and presented me with options for the ideas I had in mind. It was also a very fair price for the work required and involved. He produced a contract which put my mind at ease somewhat and protected us both. He was punctual, honest, polite, knowledgeable and hard working. His work was to a really high standard and quality. Every day he left the site as clean and tidy as could be under the circumstances. He communicated well with us throughout ensuring we knew what he had done, what was still to be done and how and when he was going to do it. The final finished patio is fantastic, I love it. He started when he said he would and despite some vicious weather he finished ahead of schedule. If you want a great job for a fair price completed by an honest hard working grafter and tradesman then Keith is your man. So much so that he will be the only person I will approach to do any further works I may need in the future. I wouldn't hesitate to recommend him to anyone. Five star quality. Top Man

Extensions- 17 Aug 2026
I had a very poor experience with this contractor and would strongly advise potential customers to be cautious before paying substantial sums in advance. I paid £3,672 by bank transfer following an invoice for the supply of structural steelwork. There were significant delays and communication issues, and the steel was not supplied to me as agreed. After giving him opportunities and clear deadlines to resolve the situation, I terminated the agreement and had to make alternative arrangements to keep my project moving. Most concerningly, despite my requests, the £3,672 I paid has still not been refunded as of the date of this review, and I am now pursuing the matter formally. Based on my experience, I cannot recommend this contractor. I would advise anyone considering using his services to be extremely cautious about making advance payments. I will update this review if my £3,672 is returned.

Corinth Contractors from the beginning was a delight to work with upon our project. Some issues arose through the works as it was a fairly large project but quick solutions were presented!
