This isn’t the first time using Heatco as I use them for maintainer and gas safety checks, Darren is very helpful even if I need to call and ask a question he always goes out his way to help, Heatco are a very professional company who put their clients first, are always on time and reasonable with their cost, will definitely use again and always recommend them to anyone needing a plumber or gas engineer

Darren came to check out the issue within 24hrs of my logging the call. He confirmed what I suspected that it was a problem with the timer. Batteries were replaced and my heating was up and running within 30 minutes. Darren provides an outstanding professional service. He is very approachable and easy to do business with. Comes across as a first class tradesman. I would recommend Darren to my family and friends. Excellent service.

Called HeatCo on Tuesday am to register a broken heating system. Darren came round early afternoon to fix the problem - no waiting time, very professional and pleasant to deal with. Would highly recommend their service. Excellent on all counts.

We have been members of HeatCo's Heat Club for years and have always had great service from the team there - on this occasion Darren. Their booking system and communication are excellent and they're a friendly and really helpful firm. Very happy to recommend them to others.

We have been using Heatco's services in the last 3 years. They installed a new boiler, serviced it and also completed small plumbing jobs. They are efficient, fast and courteous. Online booking system is very good.

Great service from Heatco. The initial booking system was easy to use and meant we could choose a suitable time for our tenants. They called the night before to check the parking situation and turned up on time and very efficiently did a great job servicing the boiler and doing a landlord gas safety check. The paperwork was sent by email the same day and the cost was reasonable. I will definitely book them again next year and am happy to recommend them. All in all it was a very good experience and I was very happy. Thank you.

Always great and friendly service from this company. So efficient and prompt. Darren arrived at the time I had booked. I received a text beforehand to confirm that he would be with me in about twenty minutes. Darren considerately removed his shoes before coming through the house. I cannot fault the incredible and reliable service I have received over the years. Thank you guys.
