Ofgem, the energy regulator, is due to announce the latest price cap on the cost of a unit of energy at 7am, and analysts expect the cap to go up, due to recent increases in wholesale gas and electricity prices.
Thie prompted energy secretary Ed Miliband to write an urgent letter to Ofgem, saying the price rise means the energy regulator must move faster to protect consumers.
The energy price cap sets the maximum that a supplier can charge for a unit of energy (there’s no cap on how high a bill can go).
7am GMT: Energy regulator Ofgem announces UK energy price cap for April-June.
Last week, a Whitehall source told the Guardian they expected bills in England, Scotland and Wales to increase by about £9 a month over the next three months in another challenge to government plans to tackle the cost of living.
