Mark was recommended to me and with good reason. He was the third plumber/heating engineer to attend in the 8 days we were without heating or hot water. Expensive solutions had been diagnosed by the others e.g. new boiler! They say that planning is the key to success... In advance of the appointment, Mark asked me to send photos of the boiler, the pump the immersion valve etc. On the day of the appointment he attended with his (very polite, articulate and proficient ) young apprentice. They were outstanding. Heating system drained, pump replaced, radiators warm and hot water restored within 90 minutes of arrival. Having received the photos, he had been able to ensure that he had all possible parts on board should they be required. I am very impressed by the professionalism of all aspects of Heat Tech, not least as the problem was swiftly identified and fixed at a fraction of the cost I had been advised by the companies.

Mark from HeatTech performed a full service on my boiler. He was excellent. Very diligent and thorough and communicated and explained everything he was doing as he worked on each task. I felt very confident that Mark was performing a very diligent service. He spent time, was not rushed or agitated in any way. Mark was recommended to me by a colleague and I will definitely use again.

Mark and his apprentice arrived promptly to carry out a radiator repair which I had requested only a few days prior. The work was carried out quickly and efficiently, with zero mess. This is not the first job that Heat tech have carried out for me, and I have always been very satisfied by the quality and efficiency of their work. "Full marks"!

I needed to upgrade an existing radiator in terms of size and power. As I had hardwood flooring it was also necessary to adapt the existing pipework for the existing 400 to be extended to accommodate a 600. The work was excellent and completed efficiently. Mark was assisted by an apprentice I was extremely impressed by the clarity of his instruction to the new member of staff. This was similar to that I was privileged to enjoy at the quotation quotation stage. The cost was within budget and initial quote. Most definitely a professional whom I would welcome back.

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.

Excellent service from HeatTech. They were very helpful with my problem over the phone, got in touch when I had asked them to, quickly arranged a visit to sort the problem out, and worked quickly, efficiently and tidily to carry out the work. No hanging around, had the relevant parts to hand, and charged a reasonable price

Mark has done three pieces of work for me since February -- bringing my heating system back to life, facilitating access to my main water stopcock and remodelling my shower. All done with skill and speed and to my complete satisfaction. In addition, he is always pleasant and helpful. I would certainly approach Mark if I needed any further work done.

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.

I almost feel reluctant to recommend as I don’t want him to get so busy he can’t come and rescue us! Having lived in the area 15 years our plumbing experiences have been pretty dire before meeting Mark. He is prompt, gets on with it and doesn’t over charge. This last job was a proper rescue job for a flood on a Sunday morning and he was there within the hour.

Our heating/hot water system failed us over the bank holiday.... no hot water. I phoned Mark at 8.30 am on Tuesday, and he was at our place by 9.45, diagnosed our problem, and had replaced the faulty part in 40 minutes. This is exemplary service ..... I know Mark has a very full work schedule. I also admire the fact that Mark was accompanied, as he has been on previous occasions, by an apprentice ( on this occasion a young woman) who he was instructing and giving hands on experience while he worked. On the whole highly skilled and experienced trades people who work for us are reluctant to take on apprentices ..... it's easier just to do the work yourself, and the paper work is daunting. Some of these are near retirement, and a lifetime of experience will go with them. So well done Mark for passing on your skill to the next generation.

Boiler repair

Around lunchtime we realised that we had lost heating and hot water. Looking at the boiler it was obviously dead. We called Mark Ockenden at Heat Tech and he called back within 20 minutes. He came to the house as soon as he had completed his other work for the day. It was clearly a difficult problem to resolve but he persisted and a replaced transformer got our boiler working again. It was clear that Mark was going to spend as much time as necessary to get our boiler working again. Excellent service.

It was a Friday and Mark couldn’t get to me during the day (already had jobs booked in). He called me back and talked me through (very patiently) what i needed to do to get the heating going again. We have used him before also and were very satisfied with the quality of his work. Knowledgeable, trustworthy and honest. Recommended

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.
