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.

Just over 1,000 homes in Northern Ireland which were supplied electricity by small provider Open Electric have been transferred to Power NI after the regulator revoked its licence. If you were an Open Electric customer, you won't lose your electricity supply, but it's still unclear if you'll get your money back if you were in credit.

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.

EDF Energy is cutting gas prices from January but will increase the cost of electricity from March, meaning dual fuel customers on its standard tariff will pay 1.2% more overall. If you're on its standard tariff you're almost certainly overpaying already, so check NOW if you can switch and save.

Ovo Energy has agreed to pay £58,000 to charity after its agents missed appointments with customers, or turned up late, and then failed to compensate them as required by the regulator.

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.

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.

British Gas and E.on are freezing the price of their standard variable tariffs until at least the end of March 2017, hot on the heels of a similar move by rival supplier SSE last month.
