Thanks for those details. This seems to be a widespread problem but, for
some reason, it's not much reported. I did find this article in the Sun
from last October.
"British Gas has made another perverse change to the way customers
pay energy bills, The Sun can reveal. It comes just weeks after the
supplier quietly ditched giro slips from thousands of customer bills.
"Now British Gas has also removed its bank account number and sort
code from the bottom of customer bills.
"It means that thousands of customers might be duped into thinking
that they no longer have the option to settle their bill by bank
transfer using faster payments."

Rather coyly the newspaper article doesn't print the sort code and
account number either.
A British Gas Spokesperson said: "The vast majority of our customers
"pay their bills successfully by direct debit, card or cheque. "Any
customer who wants to pay by bank transfer can contact us and we'll
help them to do that.
I did the sort of £1 test payment that you mentioned to their old
collection account and if that fails to show up onm y bill I'll try the
account you posted. For the record, this was their old collection
account:
