An analysis of 797,175 currently-valid commercial (non-domestic) Energy Performance Certificates on the government register. The median commercial EPC rating is C (68). Lower scores are better for commercial buildings. Data updated 2026-05-31.
These figures come from the latest certificate per building on the government non-domestic EPC register for England and Wales. Whether you are a landlord planning a let, an investor assessing portfolio risk, or a sustainability manager benchmarking your estate, the numbers below give you a clear picture of where commercial stock sits today.
Methodology note: figures use the latest currently-valid certificate (lodged within the last ten years) per building on the government non-domestic EPC register. Expired certificates are excluded, because old certificates are often superseded by a re-assessment that the register does not link. Floor areas and some fields are self-reported and may be incomplete, so treat figures as estimates.
Under the Minimum Energy Efficiency Standards (MEES), a commercial property rated F or G cannot legally be let without a valid exemption (the minimum has been EPC E since April 2018). 2.1% of assessed commercial buildings in England and Wales are rated F or G today.
The government's stated goal is to raise the minimum standard to EPC B, with an interim EPC C step under consultation. These are proposals, not yet law, and the dates are not confirmed. On that basis, 38.8% are below C and 73.4% are below B today, so a large share of stock would need improvement works if those proposals become law.
If your building is currently rated F or G, it cannot be let under current MEES rules without an exemption. Easy EPC provides MEES consultation services to help landlords identify the most cost-effective route to compliance.
A commercial EPC is valid for ten years. Once it expires, a new assessment is needed before the property can be sold or let again. If your last certificate was lodged more than ten years ago it has already expired, so it is worth checking the lodgement date well ahead of any sale or letting to leave time for a new survey. The figures on this page are based only on currently-valid certificates (lodged within the last ten years), so they reflect the commercial stock that holds a live EPC today.
The table below shows the percentage of commercial buildings in each EPC band across England and Wales. For commercial properties, the scale runs from A+ (most efficient) to G (least efficient), with lower numerical scores indicating better performance.
Bars are scaled to the most common band. Green = A+ to B, amber = C to D, red = E to G.
The median band is C. Commercial EPC scores run in the opposite direction to domestic ones: a lower numerical score means a more efficient building.
Buildings with air conditioning systems over 12 kW are legally required to have a TM44 air conditioning inspection. 20.1% of commercial buildings on the register report air conditioning, pointing to a significant proportion of properties that need to keep their TM44 inspection current alongside their EPC.
