British Gas

Co-operative Energy has blamed ongoing problems with its new IT system as the reason why it was the most complained about energy provider in the third quarter of the year.

British Gas customers should change their passwords now as the energy giant has revealed it suffered a "data leak" last night affecting just over 2,000 customers.

British Gas is axing its existing Nectar rewards scheme in December meaning customers will no longer earn points simply for being a gas and electricity user.

British Gas is to cut gas prices by 5% for the second time this year – but even after that, its standard tariffs will cost on average £250/year more than the cheapest.

Co-op Energy was a customer service darling last December, with 63% of its customers rating it great and just 7% rating it poor. But in a staggering turnaround, just six months later over half of its customers (56%) rate its service as poor and just 22% rate it great. 

Energy firms are facing increased pressure from the Government to pass on a fall in wholesale costs – the price providers pay for energy – to consumers by slashing household bills.
