Annual boiler service
Customer Service

I selected HeatTech on the recommendation of a neighbour. Communications were good - when the engineer was delayed by his previous job he rang in plenty of time to explain that he was going to be late and why; if only more tradespeople would do this. When he arrived, the engineer was polite and effected the service efficiently. I certainly plan to use HeatTech again and am happy to recommend them.

Annual boiler service

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.

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.

Heat Tech completed a boiler annual service and safety check. It was the first time we'd used them and we selected them primarily because they were local in Chorleywood. Very pleased with their professionalism and service. When booking Mark called me back as promised, he arrived when he said he would and completed the work quickly and was clear, patient and polite in explaining what needed to be done. Will use again and would recommend to others.

Everything about Heat Tech left me feeling pleased that we decided to invite Mark and his team to help us out. They telephoned us when they said they would, arrived punctually to do the work, were considerate and polite in explaining what needed to be done and completed the work very professionally. Also Mark resolved what could have been quite a complex repair very quickly and straightforwardly - saving us potentially a lot of money in the process. So we now have a fully functioning hot water system, a repaired toilet cistern and discovered someone in whom we have a lot of confidence. This was the first time we have used Heat Tech - I will have no hesitation in working with them again when we need some heating or plumbing expertise.

My toilet flush was getting worse and worse and eventually I decided to look for a plumber. I realised that Heat Tech, who serviced my boiler, also did general plumbing. Mark came the same day I rang him and sorted it all out. Couldn't ask for better service!

I found Mark on the Which Trusted Traders' site and rang him for help. I had been left without hot water for a week after the company I have insurance with for maintenance on our central heating, supposedly serviced our boiler. Their engineer returned to my house four times and each time failed to remedy the problem. Mark spotted what was wrong almost immediately and the hot water was back within the hour. He even fixed a problem with my outside tap while he was here. I cannot recommend him highly enough. Needless to say I have cancelled the contract with the heating insurance company and I will be using HeatTech for all future maintenance. Megan S.

Mark was recommended to us a few years ago by another of his clients and we've been contacting him for all our plumbing needs since then. From fitting new boilers, to repairing redundant (but still live) mains supply pipes leaking into our kitchen, to replacing troublesome toilet seats, his service is always completely satisfactory, perfectly prompt in an emergency and very pleasant. I wouldn't hesitate in recommending him to others. In fact, I already have done.

Would recommend using Mark and his team. Mark came and discussed options on new heating system explaining to this "old lady " in great understandable detail. The work was done while I was away and I came back to a very warm clean house. Thank you George. Mark again explained the running of the boiler. Mark is a very pleasant person to deal with. I understand from my neighbours that the whole team were very friendly and considerate. Thanks everyone. Not the cheapest but certainly the best. Will certainly keep using Heat Tech.

Mark and his team fitted a new boiler and hot water tank in four days. They were prompt, tidy, and explained all the work they were doing. Prior to the work, mark had explained the alternative solutions. Whilst at the top end of the estimates I had, I would not hesitate to recommend them as the result has given me an excellent system.

Without reservation, Mark was the most professional tradesman I have encountered. Makes me wonder what the annual service provided by British gas, HomeServe, CORGI Home Plan, for which I've spent a fortune these many years, actually did Uday Hegde

My central heating stopped working and Mark was able to tell me over the phone how to get it working again until he could he could come and fit a new motor to a motorised valve. Mark has serviced my boiler and heating system for several years now and I have always found him to be very reliable and has always does a very neat job.

New central heating system

We had a new heating system installed with a combi boiler and some replacement radiators. This also involved taking away all the old water tanks and piping. The job took a week and we were delighted with the quality of the work and the team were polite, clean and tidy and a joy to have around. The new system works beautifully and we would recommend Heat Tech unreservedly.

We are SO relieved to find a heating engineer that is honest and professional. Just before Christmas, we very nearly fell victim to an unscrupulous plumber who insisted that a new boiler was our only option when ours failed. The hard sell made us very uncomfortable so friends recommended we call Mark. Thank goodness we did! Mark was able to identify the problem immediately - and very kindly took the time to explain how he was going to fix it. Thanks to his knowledge and skill, our boiler is now up and running and there was no question we needed a new one! I'm so grateful for Mark's honesty and have absolutely no hesitation in recommending him.
