Gas Work- 7 May 2019
Jason was a breath of fresh air. He is highly professional, totally ethical and has great integrity. Unlike many engineers who took no time in quoting me for a brand new boiler,Jason checked the boiler to accurately ascertain what precisely was wrong with it in order to determine whether a new boiler was necessary at all. He identified the problem to an external loose valve above the boiler which was leaking. He kindly tightened the valve and stopped the leak. My sincere thanks to Jason for saving me in excess of £3000.00!

I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.

Groundwork & Foundations- 7 Feb 2026
Oli carried out the groundworks and demolition at my property and was on site every day with his crew, fully committed and hands-on throughout the job. I am an architect, and this was work on my own home, so my expectations were high. Oli met those expectations fully. He has a strong knowledge of groundworks and demolition, works carefully and methodically, and you can tell he genuinely enjoys what he does and takes real satisfaction in delivering the work exactly as required. He was always in a good mood, easy to communicate with, and a pleasure to have on site. I enjoyed discussing the project and hearing about other jobs he has completed over his 23 years of experience, which clearly shows in the quality of his work. I would highly recommend Oli for any groundworks or demolition works.

A great experience. Work was completed quickly and to a good standard with an unexpected extra (sorting out the electrics for a light in the crawl space). Most tidy builders I have ever employed. Quick responses and good communication. I'd happily use Prime Contractors again

Extensions- 30 Sep 2025
Overall, I’m very pleased with the work Marin has carried out for us and I’m currently in the process of instructing him to do more work. Marin built a high spec cedar shed for us with electrics and plumbing, some brickwork and laid composite decking. Marin came across, honest and reliable, which in itself is rare. He was on site most mornings to make sure his tradesmen were on the right tracks. Like with a lot of these things there were some issues along the way and I was highly impressed by Marin’s ‘no quibble’ approach to rectify any problems. I myself have a high attention to detail and am quite indecisive (nightmare client) and Marin was happy to work with me with changes to the project without incurring extra costs.
