Households residing in properties with the poorest energy efficiency ratings are facing a significant financial blow, with their annual energy bills projected to rise by £591 from today, 15 July 2026. This substantial increase coincides with the latest adjustment to the energy price cap, which disproportionately impacts homes that are older, less insulated, and inherently more expensive to heat.
The hike underscores the persistent challenge many UK households face in managing their outgoings, particularly those living in properties classified with lower Energy Performance Certificate (EPC) ratings. These homes, often characterised by single-glazed windows, uninsulated walls, and inefficient heating systems, require considerably more energy to maintain comfortable temperatures, leading to higher consumption and subsequently larger bills under the revised cap.
For many families, this additional £591 per year will represent a considerable strain on already stretched budgets. With ongoing pressures on food prices and housing costs, the cumulative effect of rising utility bills could push more households into financial precarity. While specific figures for average food price increases vary, the general trend has been upwards, adding to the cost of living crisis gripping the nation.
Government support schemes, such as Universal Credit and the Warm Home Discount, are available to help eligible low-income households manage their energy costs. The Warm Home Discount, for instance, provides a one-off discount on electricity bills for those who qualify. However, for many, these measures may not fully offset the significant increase now being levied on inefficient homes. Citizens Advice and MoneySavingExpert offer valuable resources and advice for individuals seeking to understand their eligibility for support and explore ways to reduce their energy consumption.
To mitigate the impact, homeowners and renters in less efficient properties are encouraged to explore immediate, low-cost measures. Simple steps like draught-proofing windows and doors, bleeding radiators, and ensuring lofts are adequately insulated can make a noticeable difference. Longer-term solutions, such as upgrading to more efficient boilers or installing double glazing, while requiring initial investment, can lead to substantial savings over time. Organisations like Citizens Advice can provide tailored guidance on energy-saving improvements and potential grants available.
