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.

Install 2 new thermostats and review operation of heating system

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.

Planned for Mark to visit at the end of May to review current heating solution. Investigation identified a problem with the heating pump. This was replaced very efficiently. Very happy to recommend Mark and am pleased I now have his contact details.

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

We were delighted with Mark's quick response to our needing the magnaclean serviced. He also told us what to watch for in the pressure of the boiler and made us feel much more confidant about the whole system. We would certainly ask him to do our service next time.

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

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.
