Energy customers whose accounts were in credit when they closed them have been refunded almost £670 million over the past two years, according to Ofgem figures – which also show £97 million is still owed to in-credit customers. Contact your former supplier ASAP if you think you're among the many consumers owed money.

Energy giants British Gas and Npower have been wrongly telling customers coming to the end of their fixed-term contracts they'll have to pay exit fees if they switch to a different provider, MoneySavingExpert.com can reveal. Don't be fooled though – if you're in the last 49 days of your fix, you CAN switch penalty-free.

Gas and electricity provider GB Energy ceased trading at the weekend and the regulator Ofgem has appointed Co-operative Energy as the new supplier for the firm's 160,000 customers. Ofgem's also announced that Co-op Energy will be honouring customers' existing fixed tariffs.

Hundreds of thousands of Co-operative Energy customers will receive a share of compensation totalling £1.8 million after energy regulator Ofgem identified problems with the company’s complaints resolution, call handling and billing processes.

Hundreds of thousands more vulnerable energy customers will be able to access a register to get support with meter readings and identifying supplier representatives from the start of next year, under new Ofgem rules.

Energy watchdog Ofgem has launched an investigation into supplier 'E' following concerns over the company's sales practices.

Energy giant E.on has paid out £1.2 million to customers and a further £1.9 million to energy charities following discussions with the regulator Ofgem, after it failed to offer compensation when its agents missed appointments.

Customers who recently made a complaint to their energy supplier are less satisfied with how it was handled compared to two years ago, Ofgem has revealed, with Npower considered to be the worst supplier at handling complaints.
