Don't use this company. We were warned but fell for it. For four years we have happily paid a rising amount for a service contract and they have serviced our boiler accordingly. This year we booked our annual service and paid for it and a week later received a call demanding more money as the boiler is in their words "out of warranty". They seem unable to explain this to us on the phone but have gladly cancelled the service and refunded our money. We are left with a thermostat that we have never understood that has never been replaced despite us asking (the engineers that came never understood it either). Seems to us that we have been dropped because as the boiler ages they are in more danger of having to repair it! Its a shame we have to even give them one star.
