When my boiler stopped pairing with the thermostat, Joseph from technical support could not have been any more helpful.
He promptly replied to any of my emails and was always very helpful.
Through a process of elimination he was able to diagnose the fault and told me which piece of equipment I needed to replace.
Everything is back working now and I did not need to call out a heating engineer so he saved me a small fortune!
Would not hesitate to recommend the technical department and would definitely use them again should the need arise.
