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.
The big six energy companies could face a full-scale investigation into whether they are preventing competition in the market and making excess profits, reglator Ofgem has announced.
If you've switched energy provider in the last six years, you could be owed a slice of £200 million after energy regulator Ofgem found the big six suppliers guilty of failing to return money to millions of former customers.
The big six energy suppliers will be fined if they fail to meet new rules aimed at helping smaller firms break into the market, the energy regulator says.
