Our gas boiler failed on the Saturday morning before Christmasand would not reignite. This required a call out and action to avoid not having heating over the Christmas period with little time to resolve the problem. Mark gave technical advice over the phone to try to resolve the problem but without results it required a visit late on Saturday afternoon. He analysed that it was a control valve problem and replaced the part from his stores in the van which avoided further delay or a return visit. Excellent speedy service at a reasonable callout price delivered politely and I would recommend Heat Tech Services. Andrew Gibson

Hot water tank repair

A leaking hot water storage tank left us without any hot water on the last weekend before Christmas. After calling Mark (whom has done work for us before) on a Saturday afternoon he was with us early evening same day and sorted the problem quickly. With a new valve fitted we were up and running again. I wouldn’t hesitate to recommend Mark - hugely knowledgeable and gets the job done without fuss.

We needed a plumber who was qualified in working on unvented pressurised hot water systems to replace a pump, some radiator valves and venting equipment. This included draining the system and refilling, pressurising and testing. Fortunately we were aware of Mark Ockenden of Heat Tech Services from a previous job and knew him to be an excellent engineer for this type of work (and a wide range of others of course). Mark provides a very efficient and punctual service with excellent communications. We were able to discuss the job by means of emails with photos so he was fully prepared for the work on arrival. I felt very confident in Mark's skills and advice. The work was completed very quickly in a calm and tidy manner and the hot water system is working perfectly again.

Mark came round to add new heating elements into my electric hot water tank as my hot water was not heating properly (after nearly 20 years with the previous elements). He responded to my initial inquiry quickly, took the time to listen to my problem, and gave me a clear plan of what he would do to fix it. He gave me a very accurate quote and was upfront about all costs. I found him to be professional, knowledgeable, and very friendly (he even took the time to help explain some other aspects of how my hot water tank works which I really appreciated). I trusted him completely and would certainly recommend his services (I initially found Mark through a 'Which Trusted Traders' search). I'm really enjoying having hot showers again - they're better than they've ever been in this flat.

I texted Mark when my boiler was not firing up. He immediately called me back and we discussed what was happening. When the immersion heater also did not work on Saturday Mark was very responsive and came out to see us on Saturday morning. Very reliable and helpful

This job was a bit of a nightmare for Mark as the original extensive wiring was shambolic and had to be replaced . In addition one of the new thermostats proved to be faulty and an existing valve had seized. Nevertheless Mark soldiered on and finished the job to his usual high standard.

Heat Tech were asked by us to quote after hearing great reviews from other customers. We went ahead and everything happened as explained and planned. The actual week long work flow went like a dream. Our 18 radiators were cleaned out, the new boiler fitted, tested and working. What was special was that Marl and his team were on time and took time to explain each step. Mark also worked out a smart way for our complete new heating system to avoid unsightly external pipe work so that everything is neatly confined within the roof space. All work was also made good to a very high standard. Mark and his team also worked through the UK's hottest days on record. I highly advise others to contact Heat Tech on any major domestic heating or plumbing project.

I have used Heat Tech over the past 3 years to repair a boiler then annually service the boiler and prepare gas safety certificates together with installation of a new radiator. He is reliable, professional and courteous and I would recommend his company.

On the recommendation of a neighbour, I arranged for HeatTech to provide an annual service for my boiler. Arranging the appointment was easy. On the day, the engineer realised that he would not complete his previous job in time to meet the appointment time for me, so called with an explanation and a revised ETA - if only more tradespeople would do this. He met the revised ETA and carried out the service efficiently. I will use HeatTech again and, like my neighbour, am happy to recommend them.
