A recent analysis by Rightmove has highlighted a significant issue: more than 18 million homes in the UK have an Energy Performance Certificate (EPC) rating of D or lower, representing over half, or 55%, of the nation's housing stock.

Government data underscores the stark disparity in energy costs between homes of different EPC ratings. For instance, a three-bedroom house with an EPC rating of F incurs an average annual energy bill of £4,431, whereas a similar-sized house with an EPC rating of C pays only £1,669 annually—a difference of £2,762.

The primary driver for homeowners to pursue greener home improvements remains the desire to reduce energy expenses. According to Rightmove's findings, 87% of renters and 83% of homeowners believe more action should be taken to promote energy-efficient homes.

Ahead of the upcoming General Election, Rightmove urges the winning party to prioritize extending green home incentives to as many households as possible and as quickly as feasible. Tim Bannister, Rightmove’s property expert, emphasized the urgency of the situation: "While there is some support for green initiatives in party manifestos, addressing the widespread issue of improving at least 18 million UK homes remains a substantial challenge."

Bannister stressed the critical need for accessible schemes to assist homeowners and landlords in making necessary improvements, which could result in significant energy savings. He pointed out the diverse needs of each home and the substantial barrier posed by upfront costs.

Without adequate support, many property owners and tenants will continue to reside in high-carbon-emitting homes with substantial energy costs, Bannister warned.

Nathan Emerson, CEO of Propertymark, echoed these sentiments, advocating for a comprehensive governmental approach: "Propertymark has long supported initiatives to enhance energy efficiency across the UK. We urge the incoming government to develop a broad package of support to facilitate upgrades."

Emerson emphasized the importance of diverse funding sources, grants, and targeted programs tailored to the age, condition, and size of properties, with a robust infrastructure in place to ensure effective implementation.

The data underscores the urgency of addressing this issue promptly, with millions of homes in need of improvements to enhance their energy efficiency. Decisive policy action is crucial to advancing sustainability in UK housing.
