Your Guide to EPCs

An Energy Performance Certificate (EPC) measures a property’s energy efficiency on a scale from A to G, with A representing the highest level of efficiency and G the lowest. England and Wales introduced EPCs in 2007, and the law still requires one whenever you sell, let or build a property. Once an assessor issues an EPC, it remains valid for 10 years, although many homeowners now update theirs sooner after making improvements or to reflect changing regulations.

Properties with an A or B rating typically cost less to run and attract more interest from buyers and tenants. As energy prices and environmental concerns continue to influence the property market in 2026, buyers place greater importance on EPC ratings than ever before. An EPC also measures a property’s carbon emissions, helping buyers understand its environmental impact. Homes with higher ratings generally produce fewer emissions and offer greater sustainability.

Most UK properties still sit within EPC bands D and E, but homeowners continue to improve their ratings. Buyers now consider energy performance much more carefully and often factor the cost of future upgrades into their offers. Every EPC also recommends ways to improve efficiency, including adding insulation, upgrading heating systems or installing renewable technologies such as heat pumps or solar panels.

Commercial properties also require EPCs, with a stronger focus on carbon emissions. As businesses prioritise sustainability, energy efficiency increasingly influences commercial property decisions.

Minimum Energy Efficiency Standards (MEES)

The government introduced the Minimum Energy Efficiency Standards (MEES) in April 2018, making it illegal for landlords to let most privately rented properties with an EPC rating below E. These rules remain in force in 2026, while the government continues to pursue higher energy efficiency across the housing sector.

The government has also proposed stricter standards that could require rental properties to achieve a minimum EPC rating of C later this decade. Although implementation dates have changed, many landlords already invest in energy efficiency improvements to protect the long-term value and rental appeal of their properties.

Landlords who fail to meet the current MEES regulations risk fines of up to £5,000 for residential properties, with much higher penalties for commercial buildings. Some exemptions apply, including certain listed buildings where energy improvements would significantly alter their character.

Although sellers don’t currently need a minimum EPC rating to sell a property, a poor rating can reduce buyer interest and affect the final sale price. Many homeowners now improve their EPC before putting their property on the market.

What Does an EPC Assessment Involve?

To obtain an EPC, you’ll need to instruct an accredited energy assessor to inspect your property.

The assessor will access every room and, where possible, the loft. They will examine insulation, windows, heating systems, heating controls and other key features before taking measurements and photographs. The assessment remains quick, straightforward and completely non-invasive, as it only requires a visual inspection.

The length of the visit depends on the size and layout of your property, but most assessments take less than an hour. After completing the inspection, the assessor produces your EPC and uploads it to the central government register.

Many assessors now offer more detailed advice on improving your EPC rating, reflecting the growing importance of energy efficiency in today’s property market.

How Do I Get a Copy of My EPC?

If you already have an EPC, you can download a copy by searching the official government register using either your property’s address or the report reference number (RRN).

Homeowners, landlords and buyers all rely on quick access to EPC information. As energy efficiency increasingly affects property values, mortgage lending and rental demand, keeping your EPC up to date can strengthen your position in the market.

EPCs in 2026

In 2026, EPCs do far more than satisfy a legal requirement. They help buyers, tenants, landlords and lenders assess a property’s running costs, environmental impact and long-term value. As energy costs continue to rise and regulations evolve, a strong EPC rating can make your property more attractive, more valuable and easier to sell or let.
