HeatCo installed a new 35kW Worcester Bosch system boiler Dec 2024 and did a brilliant and thoroughly professional job, including leaving everything clean and tidy. The system has been problem-free since installation. The latest job was the first-year boiler service. This was done by Darren, the Senior Engineer, who ran diagnostics on the boiler and cleaned out the magnetite from the boiler filter. All done on time and at a very reasonable price. We have wet underfloor heating, and Darren provided helpful advice on optimising this within the central heating system.

Darren arrived on time and completed a full service of the boiler. He also repaired an inoperative radiator valve while he was here. This was all completed quickly and at a reasonable price. We are very happy with the work done.

HeatCo & Darren - Excellent, Urgent Boiler Repair!

I cannot recommend HeatCo, and specifically their engineer Darren, highly enough. ​We had an urgent boiler issue on Monday, and I was incredibly impressed by how quickly Darren responded to my message. He managed to fit us into his schedule on the very same day, which was a huge relief and a testament to their commitment to customer service. ​When he arrived, Darren was super professional and extremely thorough in diagnosing and fixing the problem. Not only did he resolve the immediate issue, but he was also super helpful, taking the time to give us valuable, easy-to-understand tips on preventing future problems and maintaining our system. ​The fees were incredibly reasonable, especially for such prompt, same-day emergency service. HeatCo delivered exceptional value. I already recommended Darren and HeatCo to all my friends and family—they are the definition of reliable, expert service. Thank you!

We’re part of Heat CO’s club and when our boiler stop working they carried a repair and got everything working the same day. As always, Joe and the team are so helpful and friendly, backed up by a great engineer in Darren. Highly recommended.

Heating stopped working and other Central Heating plumbers were unable to identify or fix the problem like Paul at Heatco immediately did. He was able to identify the locality of the flow blockage stopping hot water flowing around the GCH system, remove and flush the pipes to have the system up and running a few hours later....
