Energy customers could be given more protection if proposals by regulator Ofgem to introduce additional stress-testing to reduce the chances of suppliers collapsing are acted on later this year.

The levels at which a temporary prepayment price cap that's expected to help four million households save about £80/year have been set by energy regulator Ofgem.

Regulator Ofgem is pushing ahead with plans to encourage customers to find the best energy deals, with a series of trials taking place that will include forcing suppliers to reveal cheaper tariffs offered by rivals.

Small energy supplier Green Energy has harnessed smart meter technology to launch the first 'time-of-day' tariff for domestic customers. But while the tariff offers good value if you're able to be flexible with your electricity use, others could find savings hard to come by.

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 customers may have to fork out £30 more a year on their bills by 2020 to prevent winter blackouts sweeping the country, a group of MPs has warned.

British Gas, E.on, SSE and some smaller suppliers have announced energy price freezes till the end of winter. Yet if you're one of the 66% on one of their standard tariffs they're typically freezing you at £200/yr MORE than the cheapest.

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.

A billing error which led to British Gas customers having their direct debit payments taken twice may have affected thousands of people, MoneySavingExpert.com has learned.

Energy switching is at a four and a half year high proving that customers are becoming increasingly savvy about cutting gas and electricity costs - but prices are now on the rise and the cheapest deals are disappearing fast so make sure you switch ASAP.
