Darren performed a boiler service for us and fitted a new thermostat unit. I had previously stated that this might be needed as the control unit had physically broken and had lost contact with the boiler unit. I received a call well in advance of the expected start time to say that he had been delayed on his first job and would be about 30 minutes late which was considerate and he subsequently arrived on time. Darren worked quickly to perform the service, confirmed the thermostat change was required and explained the outcomes of the tests he had carried out. Later that day we received the gas certificate. I would definitely recommend HeatCo, they fitted the boiler and are our first contact if anything should go wrong.

Wholeheartedly recommend HeatCo. Easy booking of appointment for Combined Boiler Service and Gas Safety Certificate. The online system confirmed booking immediately and provided 2hour slot on the chosen date. Friendly, efficient service and small repair of boiler. Landlord and gas certificates were issued and emailed the same day. Thank you very much HeatCo.

Darren arrived on time to service the gas boiler. As usual Darren just got on with the work and left everything clean and tidy after he had completed the service. I would certainly recommend Darren and HeatCo.

Darren was excellent, called me early, arranged to come to site before the appointment and it was done and dusted in just over 30 minutes. Always polite and friendly and cleaned up after. I can’t recommend HeatCo any more highly!

Darren came, identified what was causing the problem, nipped out to purchase a replacement flush push button, and fitted it, leaving the toilet working as normal. As usual, Darren was very professional and customer-focused. Highly recommended

Darren replaced a faulty controller panel, having very kindly come out 2 days earlier at very short notice.

As usual, an absolutely first class service. The efficiency in terms of fault diagnosis and then coming back to replace the panel having sourced the part in very quick time was excellent. Thank you.

Shaun gave advance warning when he would arrive. Carried out the service and provided feedback on the condition of the boiler and when should be booking the next service.
