Questionable 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.

The trader replied (on 08/11/2023)
We are very sorry that you felt our service was not up to scratch. Expansion vessels are particularly prone to failing after a few years and this can happen at any time, even shortly after a service. At the time of the service the vessel air pressure was low, which is not unusual (and one of the reasons why regular servicing is important). It was topped up with air in the usual way. If the internal bladder, which is impossible to see, had been weak, it may have been the final straw which caused it to split a few days later. We did try to re-inflate it when you called us back but it had clearly failed, so unfortunately it to be replaced. Sorry but these things do happen sometimes.
Great service!

After contacting Heat Tech about fixing our boiler, they were great from start to finish. Sapphire was very friendly and helpful, doing the best she could to fix the fault and went out of her way to come back later that day to sort it. Reasonably priced and very reliable - would highly recommend!

Fix problem with Vaillant boiler heating system and room thermostat

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.

Having tried every trick possible, I decided it was time to call in an expert. Called first thing on Monday morning and got an appointment for the same day. The guys turned up on time and within minutes the toilet was unblocked. No fuss. No mess. Professional and efficient is how I would describe the service. I can honestly say it was a pleasure to do business with Heat Tech and I would definitely recommend calling them for your plumbing problems. Additionally, I was pleasantly surprised that the bill was less than the estimate quoted. Many thanks!

I have a boiling water tap in my kitchen which is 3 years old, but it suddenly started to leak by the tank under the sink and so I needed a plumber fairly quickly. My usual plumber is good but incredibly hard to contact and never available at short notice, however, I left a message for him to call me early that morning. I spoke to a local friend about this problem that same morning and she recommended Mark to me. When I had heard nothing from my plumber by lunchtime I decided to call Mark and he answered the telephone quickly. We had a discussion about the problem which resulted in me sending pictures by WhatsApp to him. He then called me back quickly and diagnosed the problem. The following day two plumbers appeared and they worked hard to solve the problem, but alas specialist spare parts were required from the manufacturer. Off his own bat, Mark spoke to the manufacturer and managed to secure a brand new replacement tap under the warranty. The new tap was couriered to me quickly and Mark sent the same two plumbers back to instal it. All done with a minimum of fuss or hassle. To be honest I was very impressed with Mark's no nonsense approach to jobs and the initiative he showed in going direct to the manufacturer without bothering me.

I received a recommendation for this company, and used them for the first time to replace a faulty heating timer and a boiler service. The engineers did what they said they were going to do, when they said they were going to do it for a reasonable price. I am happy to recommend them without any reservations.

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.
