Energy bills in Great Britain could reach more than £3,600 a year this winter, experts have warned, with soaring wholesale prices expected to continue to push up household costs until at least 2024.

The research firm Cornwall Insight predicts the energy price cap is on track to rise to £3,615 a year from January, an increase on its previous estimate of £3,363 made last month.
