Gas and electricity supplier Spark Energy has apologised after a debt collection firm contacted a number of its ex-customers and wrongly told them they owed money - even though some closed their accounts years ago.

Energy regulator Ofgem has opened an investigation into gas and electricity supplier Iresa's customer service.

An energy price cap must be introduced by next winter to stop millions of customers being ripped off, a committee of MPs has said.

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.

All but 80 of the millions of smart meters so far installed in the UK are still first-generation meters which are likely to lose their 'smart' functionality if you switch energy provider, new figures reveal.

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.

The average water and sewerage bill in England and Wales is set to rise by £9 to £405 a year.

Customers of the small energy supplier Iresa have vented their anger over unexpected increases to their monthly direct debits – with some seeing what they pay rise despite their account already being in credit.
