I used to be covered by B gas till they did the dirty on me. Having had their breakdown cover for years we moved house. They said they would continue cover only if the new house c/h system was inspected. They gave it the al clear , all was fine till the pump packed in they would not replace it as it had failed due to muck in the system, I told them they checked the system 6 months earlier but they said they dont inspect the water in the pipes and rads. so goobye b, gas
all I do now is flush out the system every 18 mnths and fill with the inhibitors you can buy from Wicks diy Had no problems for the last 9.5 yrs.
