Thank you so much
Brilliant. We had no water. We called Mark. Within 2 hours he sent a lady plumber and her assistant. She found the problem, went out to buy a spare part, returned, and all was completed, with running water from all taps and showers working again much faster than I thought - just 90 minutes. This is definitely a company I will recommend.

Fix problem with Vaillant boiler heating system and room thermostat
Customer Service

Value
Central heating was intermittent and not responding to the thermostat. After having a couple of locally recommended engineers look at the system and fail to properly diagnose the fault I came across this Which site which contained many satisfying reviews. Talking to Mark on the phone it was very clear that he was the engineer I was looking for. As a retired engineer of 60 years in electronics development I found we could discuss my problem successfully. Heat-Tech engineer George, came over to checkout the system and found it not to be wired according to published standards and recommended that rewiring was needed to enable efficient fault finding. Subsequently he got the heating working but there were occasional fault modes occurring and a new electronics board was needed. After fitting a replacement board the system is now working correctly. Costs of labour and parts were good value and I would call them again if required. I'm pleased with the fast and competent service from the company and would recommend Heat-Tech as a first choice. Thank you Mark and George.

We needed to have a second boiler pressure gauge and filling loop installed as the existing controls were all in the loft and being in our seventies this was extremely difficult for us to access. We contacted HeatTech who gave us a quote which we thought was very reasonable and asked them to go ahead. The engineers arrived punctually were friendly and helpful and carried out the work quickly and efficiently. We can highly recommend this company and we will definitely use them again.

Full Boiler system extraction and system replacement - VERY professional

Outstanding job by Mark, Sapphire and the rest of the team. Very professional in the initial diagnosis of the old boiler system; transparent on what the problems were and the options open to me; competitive quote and invoicing process for the new combi boiler system which they recommended to replace my old system. The old boiler system was quite a antiquated installation but Sapphire and her team got to work straightaway and were simply excellent in extracting that and installing a fully functioning replacement Vaillant combi boiler and NEST thermostat system - and in a very fast and efficient time too. The Heat Tech team are highly recommended (they came recommended to me too), very trustworthy and I will continue to use their services in future.

Burst pipe late afternoon on Xmas Eve sorted quickly with no fuss. Subsequent boiler breakdown and replacement handled extremely professionally. Detailed explanations at every stage. Prompt arrival every morning, quiet except for instructions, and Covid protection guidelines adhered to by all workmen (and ladies!). Work completed on time and within budget. A small problem with the new boiler (Manufacturers' fault) was remedied quickly at no extra cost. Will be replacing British Gas insurance policy (as the earliest they could send an engineer was a minimum of 2 weeks!) with annual service by Heat Tech. Cannot recommend highly enough.

Heat Tech services (Mark) installed a new boiler for me in the summer, which was done very efficiently. In September we started to have problems with the hot water as the new boiler kept cutting out. Mark couldn't have been more helpful in identifying the problem (failing Shunt Pump) and fixing it. He ensured that we weren't left with a problem. I wouldn't hesitate to use his services again.

Leaking boiler

On New Year's Eve I discovered the central heating boiler was leaking and dripping onto the kitchen worktop. Mark came, identified that it was the heat exchanger leaking, telephoned the manufacturer and arranged for an engineer to visit on 3 January. It was all done so efficiently and was a great relief to me. Very grateful for his swift action.

The work was the replacement of an old and faulty Ch wall thermostat. The original engineer - Sapphire - was ill and unable to attend but her replacements actually arrived before the original appointment time and completed the installation efficiently and courteously. Moreover, they provided a clear, patient and thorough explanation of the workings of the new,' smart', thermostat. A very good, professional job.

The engineer arrived on time and was friendly He carried out the service on my boiler in a confident manner and was tidy and efficient. He also helped set my timer which I was having problems with. He suggested it was faulty. When I asked him if Heat Tech could fit a replacement he said yes and suggested I contact Mark Ockendon. I was extremely happy with the service.

Mark and team are brilliant. We found we were losing pressure on our boiler, and then during other works discovered a leak under the landing floor. Mark came quickly, replaced poor work by a previous plumber and replaced with proper copper pipes. With my elderly mum in the house getting this sorted was vital and Mark came up trumps. We also requested our annual heating service and had an appointment within days. Prices are very fair and Mark runs his business in a very professional way.
