It’s getting tougher still on energy bills. New analysis out today suggests costs are set to soar even higher in the coming months, higher than predicted a mere week ago.

The average annual energy bill for households in England, Scotland and Wales will reach £3,582 in October, according to estimates unveiled today by energy analysts, Cornwall Insight. That’s £200 higher than last week’s estimate. In January, when the price cap rises again, we can expect bills to reach £4,266 –  another £650 higher.

To put these figures into context, the average annual energy bill just last October was £1,400.

According to Cornwall, energy regulator Ofgem’s decision to change the price cap every three months instead of six is largely responsible for the recent jump.
