The rise means a typical household's yearly energy bill will climb from approximately £1,641 to £1,862, while larger families with greater energy consumption could witness costs soar by as much as £329 annually.‌The alert arrives as households continue to struggle with the cost-of-living crisis, with research indicating two-thirds of consumers say a 10% rise in energy expenses would impact their financial situation. Some revealed they would be compelled to draw on savings, while others would need to reduce spending on essentials such as food and transport.‌However, switching specialists say numerous households can still sidestep the increase.
