So just to be absolutely clear, are you saying that the BG contract annual charge is cheaper than a boiler service from an independent?
They both said quite clearly the warranty would stay in tact IF the bolier was serviced each year by a qualified guy at my expense. BG actually said they would do the first year free. I am under no illusion I need to maintain the boiler with a service each year to qualify for the warranty. However I am unsure as to the filter on the BAXI as I don't think BG installs one which is weird?
Cheers
