The rise in profits means that British Gas Residential made some £1.9 million of profit a day as consumers struggle to cope after the average dual fuel bill rose to £1,310 a year - more than £200 higher than two years ago.
Richard Hall, head of energy regulation at Consumer Focus, said:
"Wholesale prices rose a little earlier in the year but are now falling and they are still a long way from their peak in 2008.
"We have long questioned whether drops in wholesale costs find their way through to household bills."
Cold start to the year may have been bleak for us - but it left British gas basking in soaring profits, leading to calls for a better deal
Another energy company another rise in profits. But with significant political pressure British Gas' explanations may not win them friends
