Info req : My 1 year old combi boiler had its first service, the engineer explained its “under gassed” and needs the gas pipes changing, my house is mainly electric and only have two gas fires using gas that are very rarely on, the gas safe installer didn’t pick this problem up.
As we are pensioners the changing of pipes might be an incredible cost, as I have run for the past twelve months with no problem is this a must do job by law ?
