The average gas and electricity bill in the UK is to increase to a maximum of £1,971 - an increase of £693 a year, Ofgem has announced.
Ofgem chief executive Jonathan Brearley said: “We know this rise will be extremely worrying for many people, especially those who are struggling to make ends meet, and Ofgem will ensure energy companies support their customers in any way they can.
“The energy market has faced a huge challenge due to the unprecedented increase in global gas prices – a once in a 30-year event – and Ofgem’s role as energy regulator is to ensure that, under the price cap, energy companies can only charge a fair price based on the true cost of supplying electricity and gas. Ofgem is working to stabilise the market and over the longer term to diversify our sources of energy which will help protect customers from similar price shocks in the future.”
