A quiet factor with growing influence 
As the market adapts to changing expectations, energy efficiency is taking on a bigger role in how properties are valued. According to the ONS’s May 2025 report on private rent and house prices, homes with stronger energy performance certificates (EPCs) are increasingly attracting better offers and letting more quickly. 

What an EPC really tells buyers and tenants 
An EPC is more than just a regulatory requirement. It provides a snapshot of how much it will cost to heat, light and run a home. In an era of rising energy prices and heightened environmental awareness, buyers and renters are paying closer attention to these ratings. A higher EPC can mean lower bills and greater comfort two things that appeal to most households. 

How efficiency impacts value 

Homes with better insulation, modern boilers, double glazing or solar panels often command a premium. They are seen as future-ready, especially as government targets around emissions and building standards tighten. For sellers, an upgraded EPC can make a noticeable difference to valuation and marketability. For landlords, it may affect compliance and tenant appeal. 

Small changes, big benefits 
Improving a property’s energy rating does not always require a major overhaul. Simple steps like switching to LED lighting, sealing draughts or installing smart meters can improve efficiency. For larger works, such as loft insulation or heat pump installation, grants and incentives may be available to offset costs. 

Looking ahead 
Energy ratings are no longer a secondary consideration. Whether you are buying, selling or letting, they influence price, time on market and long-term appeal. As standards rise and awareness grows, properties with better ratings are positioned for stronger performance.
