Bought a property late last year (end of Oct). We haven't yet moved in as have some other stuff to sort out.
The gas supply was originally with British gas however when we moved in we switched it right away to EDF. Unbeknown to me, EDF didn't actually do the switch until 1st December so there was a month and a bit that we needed to pay British gas. Fine but we weren't aware (I even checked with EDF that everything was fine and they said yes and my first payment came out early December so assumed this included the last little bit of Oct and Nov too).
Anyway, due to all the Royal Mail strikes we ended up receiving a bunch of letters all in one go from British Gas first saying we needed to pay £40 and then a few more adding a couple of late payment fees because we'd not responded to the last letter (that we hadn't received due to the strikes!).
It's now up to nearly £200 they want from us with the late payment fees. If we'd have known we'd have paid it straight away! No one tried to call us and as I say we literally received all the letters in one go a few days ago!
AIBU to say we will.of course pay the original amount but we aren't paying the late payment fees.
