Louis came and explained what needed to be done and he did it. Replaced valves in a Perrin and Rowe triple tap. Worked patiently to get the old valves out and successfully installed the new valves. A job well done!

Louis was quick to respond to me and sorted my leak out early the next morning. He knows what he's doing and I will use him again

Would highly recommend, one day my hot water stopped working. Louis managed to replace the old heating element and immersion cylinder and it's all working fine. He's a genuine guy and will call again if needed in the future.

Louis was really responsive for the emergency we had and showed deep knowledge and expertise around remediation of wider issues that we hadn’t realised.

Louis was recommended to me and I would recommend him to others! He was very helpful and experienced in removing and installing my new bathroom sink and sorting out other bits within my bathroom. He did a great job and was very accomodating, I'm very pleased with the results. Thanks Louis!

Very satisfied with the service. Enquired for leak detection services and from the onset, the approach was transparent with clear indication on charges. On the day of inspection, Lewis kept me well informed of all the checks he was going to do. He checked upstairs and downstairs radiators and other obvious signs of leaks. On not spotting any signs, he then checked boiler and found an internal leak. He shot video, took pictures of leak and also mentioned its detail on his job summary. This report helped me tremendously as I was able to explain the findings to boiler engineers who later agreed to remediate the issue. Big thanks to Lewis for writing such comprehensive summary.

I recently had a serious plumbing issue in my flat — everything was completely blocked, including the bathtub, toilet, and shower area. It was a very stressful situation. Louise arrived fully prepared with all the necessary equipment and was extremely friendly and professional from the start. What really stood out was his determination to find the root cause of the problem. It wasn’t an easy job at all and required a lot of hard work. At one point, Perie also came to assist, and together they kept working until the issue was properly identified and resolved. Thanks to Louise’s persistence and commitment, the problem was finally fixed. I truly appreciate the effort and dedication shown. Excellent service — I highly recommend them without any hesitation.

I would highly recommend this company. Louis did a fantastic job on my combi boiler. He managed to find time when he was already busy, resolving the issue quickly. Will 100% use again

Brilliant service. Turned up on time, worked very neatly, and knew straight away how to fix the problem. Came out late in the evening as an emergency, which I really appreciated. Great price and excellent quality of work. Properly kitted out and very professional. Thanks!
