Energy regulator Ofgem is to blame for part of a massive increase in energy bills, with the price cap potentially hitting more than £4,200 in January.
That's according to a new dire outlook from market research firm Cornwall Insight, which said bills are set to reach around £3,582 in October - from £1,971 today - before rising even further in the new year.
Ofgem is set to put the price cap at £4,266 for the average household in the three months from the beginning of January - about £650 more than its previous forecast.
