Don't know what contract you have with them, but when I looked at their terms and conditions for most of the covers they offer, its a mine field, they have so many get outs for not repairing you may as well not have any cover, save the money and pay for a local plumber for a one off repair, I know easy said, you have to find one. BGs greatest get out is, ( if WE decide your boiler is uneconomical to repair, we will offer you a good price on a new one. A new boiler off BG is nearly twice the price as other suppliers.
