"I recently had my immersion heater cylinder replaced and couldn’t be happier with Kem’s service. Kem was professional, punctual, and clearly very knowledgeable. He carried out the replacement efficiently and made sure everything was working perfectly before leaving. He’s also been really responsive with any queries I had on the system after it was installed. What really stood out was that he took the time to offer helpful advice on a few other plumbing issues I’d been wondering about. He explained things clearly, without any pressure, and gave practical suggestions that were genuinely useful. It’s not always easy to find someone reliable and trustworthy, but this was a great experience from start to finish. I’d definitely recommend him to anyone needing plumbing work done."

Kem was super helpfull

"I hired Kem to move some gas pipes and install my oven, and I couldn’t be happier with the service. From start to finish, the process was swift and smooth. As someone who knows nothing about gas pipework, I really appreciated how Kem was super clear in explaining exactly what needed to be done. He was incredibly kind and friendly throughout the day, and all the necessary safety certificates were provided promptly after the work was finished. I highly recommend his services for anyone looking for a reliable, certified engineer!"

Fantastic unvented cylinder installation

"Kem was fantastic from start to finish. I found him on Checkatrade with amazing reviews, and he lived up to every word. Very responsive, friendly, tidy and professional, he inspected my tank, gave great advice and answered all my questions. The unvented cylinder installation was done to an exceptional standard. He installed the timer and even helped me take a photo of my water meter, which was extremely difficult to access. When my sink cartridge failed, he guided me instantly and came out the next day. I appreciate all the hard work and care he put into the job, I will definitely recommend!"

Moving a gas pipe in the kitchen for our oven

"Kem was brilliant, professional and a true gentleman. He came over in the late afternoon and did exactly what was asked and went above and beyond for us, he even helped with a little side issue we were having since moving in and figured it out in 10mins (our heating works now!). He will be our new gas engineer for the house and have already a few other bits we want to arrange with him. […] Would 100% recommend his services."

Radiators boiling hot again!

"Three of our radiators were completely freezing at the bottom due to years of sludge. Kem carried out a full chemical power flush with magnetic filtration. The difference in heat output and efficiency is night and day. Punctual, polite, and very reasonable pricing."

"Pressure was down on our Boiler, Ontime CMS (Kem) very quickly deduced from a leak the issue was related to a pipe which was damaged by previous workers at the house. He traced the leak so quickly and efficiently (saving us large ceiling damage repair costs). He sorted the pipe and went on to sort out other issues in our central heating system - radiator by radiator. In two hours the leak was sorted, boiler pressure sorted and radiators sorted. It is worth noting that top end customers service we got from comms during the call out till the repairs were done."

"Kem was able to help us with our boiler when it stopped providing continuous hot water. He is very friendly, was quick to respond, able to not only fix the problem but also explain what had gone wrong - will definitely use him again to service our boiler going forward!"

Thorough and honest boiler service

"Didn't just do a quick superficial wipe like some companies do; Kem carried out comprehensive combustion analysis, cleaned the condensate trap, and checked all seals. Highly recommended."

Neat pipework and zero mess

"Moved two large radiators during kitchen renovations and cleaned through the heating system. Excellent pipework, no mess left behind, and everything pressure tested before handover. 10/10 workmanship."
