I don’t even want to give one star - no option for zero! I’ve been paying for service care and had “annual service” done by them for a few years. Boiler packed up last week - BG engineer came - messed around with it for a bit, banged the tops of some of my radiator thermostats, and said he’d send a quote for a necessary “power flush”. Charge of £60. Left with boiler sort of working. It stopped again 2 days later. This time I called in an independent gasman, as wasn’t convinced. He took front off boiler - said it looked as though it hadn’t been properly serviced for years (last “done” in March) - filthy dirty, a metal plate missing and perished rubber seals. Showed me all this. He ordered parts, cleaned it all out and put a cleaning solution in system - left boiler working and said he’d be back with parts. Quote for power flush from BG - £880 Independent said if it’s nec after new parts - he could do for £350. All been working without the need so far. British Gas are a complete rip off and not servicing boilers correctly could surely be dangerous!! Steer clear is my advice. Needless to say, I have cancelled my agreement.
