Heat Tech Services is exceptional! From the moment I contacted Mark, their expertise and professionalism stood out. They offered clear, insightful advice that found my boiler issue quickly, with a rapid response time that far exceeded other companies. Even responding to my many questions late into the evening. Mark took the time to explain the cause in simple terms and provided tips to prevent future issues. Their engineer Frankie was knowledgeable, friendly, and went the extra mile to ensure everything was tested to the highest standard. If you’re looking for a local reliable, expert service with unmatched responsiveness, I can’t recommend this plumbing company highly enough.

Gas Leak

Had suspicious smell of gas. I decided to phone Mark Ockenden of Heat Tech Services as his firm are registered Gas Safe Engineers. I have used their services for Gas boiler installation, maintenance and general plumbing for many years. I have found his staff, well qualified and highly effecient. Mark arrived on time. He tested for a leak and determined it was minor but needed to be attended to. He found the leaking valve, which was embedded in my fireplace surround. To avoid damaging the fireplace, he lifted carpet and adjacent floorboard, cut the pipe and capped it with a soldered repair - all with my agreement. He put everything back in place and it looks just as it was before the repair was carried out. As usual - excellent service.

We have used Mark for some years before at another house to install a new boiler, annual servicing and various heating issues. Mark always responds very quickly and this time our boiler developed a fault and stopped working. Mark diagnosed the issue, discussed with us what was needed, and then ordered the parts required . The work was completed very promptly to get the boiler working and also completed servicing of our Vaillant boiler and mega flow. Mark is very knowledgeable and helpful and completed the work to a high standard. I will certainly continue to use Heat Tech in the future .

Came promptly and carried out a thorough service on our old back boiler where other firms have declined to do the work as they no longer service this type of system. Very pleased with the work carried out and the advice given, will definitely recommend.

I called Mark around 6 pm Friday as my normal plumber was booked and I had not had hot water for a week despite my boiler apparently firing up. Mark asked for pictures of my set up and then called me back to use telephone triage with very easy guidance on things I needed to check which quickly led to an over the phone diagnosis of the problem (a failed valve); Mark clearly explained his pricing which was extremely reasonable and committed to come this morning (Saturday 9 am); he quickly confirmed it was a valve problem replaced it and explained how I could run my system more efficiently . Hot water worked perfectly after a few minutes. I recommend Mark very highly and will now use him/ Heat tech for all my boiler servicing work as I was so impressed.
