Renters are only half as likely to switch energy supplier as homeowners, while one in five don't even know it's possible to switch, according to a new report by Ofgem.

Over 4,000 British Gas customers have received compensation after British Gas admitted mis-selling energy over a two-year period in supermarkets and in a west London shopping centre.

Ofgem has confirmed it's referring the energy market for a full competition investigation – the first probe of its kind.

Npower has been told by Ofgem it must meet strict targets to fix billing problems and to improve its complaints procedure or face a curb on sales, after it sent ex-customers huge bills months and in some cases over a year after they'd left the firm.

It should take as little as 17 days to switch gas and electricity supplier, after regulator Ofgem backed plans to make changing energy company easier and quicker.

Ofgem is calling on the big six energy suppliers to explain what impact falling wholesale prices will have on customers' bills, following a "significant" drop in both gas and electricity costs in recent months.

Scottish Power has agreed to pay £750,000 to charity as well as a £1 fine to Ofgem after the energy regulator found faults in the way it calculated customers' prices.

If you're an E.on customer, you could be due a share of a £20 million payout after the energy giant was found guilty of mis-selling on a massive scale by regulator Ofgem.
