p.s. I fitted the insulation myself as he didn't fit any. ive since found out he was supposed to have done this under G3. when I told the young guy he sent to sort the boiler connections, he said it probably wasn't done as its in an airing cupboard so doesn't get cold .
ive just checked him out on gas safe and hes listed as having G3.
