Ofgem

Energy regulator Ofgem is to trial a collective deal for 50,000 customers who haven't switched for more than three years - but you needn't wait to save.

Up to five million vulnerable and prepay energy customers could see their bills rise by an average £58 a year after the regulator Ofgem announced it is to increase its price cap.

The energy regulator is to investigate whether Ovo Energy gave some of its customers inaccurate information relating to how much gas and electricity they'd used.

About one million energy customers who are deemed to be vulnerable and so are given a discount on their gas and electricity should see their bills drop by an average of £102 a year, as the regulator extends a price cap. But many could actually save more by switching.

Future Energy, an energy supplier with about 10,000 domestic customers mainly in North East England and Yorkshire, has ceased trading.

Toto Energy has cancelled a steep price hike for some of its customers after admitting to a price guarantee "misprint".

Npower and E.on have apologised and paid out for misleading customers after a MoneySavingExpert.com investigation revealed many customers with fixed tariffs ending were wrongly told they'd have to pay to switch provider.

British Gas has pledged to scrap its standard variable tariff for new customers next year, replacing it with a one-year tariff with no exit fees – but it so far can't promise the new deal will be any cheaper.

Three out of five households are still paying an average £300 more than they need to for their energy despite near-record switching rates this year.

Energy regulator Ofgem has called on suppliers to do more to help those who fall behind on payments, after finding customers owe an average of more than £600 before being put on a debt repayment plan.
