Questionable service
Customer Service

Had the boiler serviced by Heat tech in September. £120 is at the expensive end for this but figured was best to pay up for a quality service to avoid unwanted expensive failures during the winter. Boiler (combi) had been working fine before the service, but almost straight away post service we started to have instances of needing to re-pressurise the system. This happened a few times so eventually called Heat Tech back in a month later to investigate, where they found a fault with the expansion vessel, despite having signed this off as working fine at the service the previous month. £265 bill to find the fault, order the part and return to replace it. Spoke on the phone, Heat Tech not interested in excepting any liability or goodwill gesture for the sequence of events or questions around the service quality. Will not be using them again.

Customer service and attitude of some of the plumbers a little unfriendly But the work done was good … Until I had a problem weeks later in the same room in a different place Was charged over £100 for the leak to be looked at And the problem was not fixed I was told I was abusive when I questioned the price … And my professionalism questioned … Quick to respond and work ok But not great if you want to complain

Poor service - Completed initial work, but impossible to get hold of for follow-up

Had issues with my radiators. Mark was very helpful initially, advising on what are the options to resolve and proposing course of action over multiple steps. Team completed the initial job, but this did not resolve the issue. Tried to speak to Mark a number of times after this - he was difficult to get hold of, refused provide a quote for the next step and preferred to say this is the cost per hour. Said he would call back but did not multiple times. Overall initial service was good, but not impressed with the follow-up and issue still not resolved

I was recommended the company by my sister and they did not disappoint. Clean, tidy, knowledgeable and helpful. Bolier service completed and the shower problem that I had misdiagnosed was found and suitable suggestions forwarded to me to decide on.

In addition to fitting a new hot-water cylinder, dealt very efficiently with replacing an old motorised central heating valve (faulty) with a new model - adapting it to an existing cast-iron piping. Cleaned up well at end of job.

The team from Heat Tech helped me to fix a small water trickling issue in the toilet bowl. I was very impressed that they brought their own shoe cover to maintain cleanliness. This is the first time I have seen a business so well prepared. They had everything required to do the job and explained the issue, quite clearly. Thank you

Mark listens, is patient - and is a clean and tidy worker, who takes away packaging and broken parts. He is polite and does the job well. If you are in trouble e.g. water overflowing, he will attend the same day after booked work. He trains apprentices.

Met Mark helping our elderly neighbour which he did cheerfully even though no work for him. Serviced our boiler and fitted new thermostat, all done efficiently by Mark and his team and everything checked and left clean - may not be the absolute cheapest firm around but worth it to get the expertise and service.

Mark's team had to switch out old boiler set up with loft tanks etc and replace with combi plus some extra rads. A big job that took all week for 2 people. Job completed as planned and all done efficiently. We had a few snagging problems but Mark made sure that one of his team came out to fix them quickly. Have used Mark before and will definitely use him again. Reliable service and good at diagnosing tricking problems!

Mark and James did a sound job with neat workmanship and advised us of potential problems with existing hidden pipework and electrics before starting, so we were able to come up with a Plan B for the works and complete everything on schedule. They have regularly carried out boiler servicing for us over the years and we would have no hesitation in recommending them.

Found Mark’s contact details when searching online for Which Trusted Traders. Repairs to a shower valve, kitchen Triflow tap and a flush cistern were needed. Most of contact with Mark was via emails where he always replied promptly and provided helpful information. Mark himself or another one of his colleagues came on the agreed date & time and carried out the required work even agreeing to take on additional items which needed attention. Mark and his colleagues were very polite and helpful and the all the work was done tidily. I can certainly recommend Mark and will contact him again when required.

We have a megaflow system that started to leak. Mark advised on the best course of action to contain the leak, while allowing us to still have hot/cold water, and had someone around the following day to fix. All done quickly and efficiently. One of the few people/companies that really understand how megaflow systems work. Thanks.

I have been using Heat Tech for all of my home plumbing/heating issues over the last 2 years. I have always found Mark and his team extremely helpful, polite and knowledgeable. My boiler stopped working a few days ago and I was left with no hot water or heating. Mark came out within 30 mins (after 6pm) and had the boiler working within the hour. I wouldn't use anyone else.

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.

We have used Mark on a number of occasions over the last six years including to install a new boiler and new Megaflow and to extend our central heating to areas of our house not previously heated. He has also done much smaller jobs, including, on this occasion, fixing a leak that had started from our shower valve. On each occasion he has spent time analysing the situation, clearly explained his proposed solution and then implemented it very professionally. I doubt he is the cheapest plumber covering Chorleywood, but I'm pretty sure he's the best.

Heat Tech re-configured the heating system in a flat I rent out. This involved installing a new combi boiler and removing the pressurised water tank system. The work was complicated and carried out to a high standard, with little mess left. My life was made easy with Mark Ockenden working directly with the tenants in a sensitive manner. The job started and finished on schedule and to budget. I have no hesitation in recommending Heat Tech as a professional and competent company.
