Darren arrived on time, is very courteous and a pleasure to deal with. Darren undertook his work diligently, cleaned up any mess and left the area round the fireplace in a clean and tidy condition. I would have no hesitation in recommending Darren's work.

Have been using HeatCo for a few years and found them to be very efficient and extremely trustworthy. Tried other companies (for various things that Heatco doesn't normally do) and have sometimes been quoted several times higher for the same thing or had unnecessary work suggested. Highly recommend!

Darren from HeatCo serviced our boiler again yesterday and as always did a great job. He arrived promptly, with advance warning, and carried out the service with a minimum of disruption. We're very happy to recommend HeatCo to others. The service is great.

Have used Heatco both for individual jobs such as moving rads and also signed up for the annual maintenance plan. The annual maintenance plan covers the boiler servicing and has taken out any worries and associated costs with unexpected problems that inevitably pop up over time on most systems. Individual jobs have always been done on time and competitively. Highly recommend.

I have used HeatCo to service my old boiler and replace it with a new one. They are efficient, courteous and professional. The cost of replacing the boiler was good value. The payment method and invoices were clearly explained and worked well. You also get text messages about their arrival time. Highly recommend.

Boiler Service & Gas Leakage

Darren and colleague arrived ahead of schedule, and in addition to carrying out a Boiler Service, also performed numerous tests to trace a minor Gas Leak revealed beforehand when a new Smart Meter had been installed by my energy company. Eventually the problem was resolved by capping supplies to a couple of unused gas appliances. Excellent detective work and prompt service at a very reasonable cost.

Excellent service from Shaun at HeatCo who fixed 2 plumbing issues. One was fitting a new plug to the the sink and the other was a new Geberit flush valve to the toilet. The work was easy to schedule with the online booking system and the appointment was kept on time. Work was performed efficiently and very professionally and ai would definitely recommend

Old boiler with intermittent fault

I originally booked HeatCo to attend because the boiler had failed. However, after not working for 24 hours the boiler came back on of its own accord. I asked HeatCo to attend anyway to check that the boiler was safe to use. The engineer checked the boiler over and gave it a clean bill of health. They suggested that we consider changing the boiler since it is nearly thirty years old but there was no pressure to do so.

Shaun fixed a leak in my house really quickly and efficiently. First, he turns up on time, acts respectfully in my home towards me, my wife and my kids. He quickly assesses the problem and then clearly explains to me what he needs to do and then gets on and does it. With all the kids off for half term it was carnage in the house with them being noisy, Shaun just got on with the job like a pro. Thanks, Shaun

Darren was excellent to deal with and responded quickly to communications. He tried to fix the problem twice before having to get a spare part. He did not charge for the extra time, just the original visit and replacement part. All is now fixed and we are very pleased. We would warmly recommend him.

Several years ago I subscribed to the company's 'Heat Club' maintenance contract and it has served me very well. For example, a plumber attended to repair a leaking pipe in the kitchen very soon after it was reported. Heatco has done several jobs for me including fixing a knocking radiator and installing SMART radiator valves in every room. The annual maintenance visit is arranged at a time to suit me. All-in-all Heatco provide a much better service than the larger operators, but at a significantly lower price. I am pleased with the service provided and intend to renew my 'HeatClub' membership when it falls due.
