How can I improve a low Commercial EPC rating?

If your Commercial Energy Performance Certificate (EPC) shows a low rating, the good news is there are usually quick wins that can lift it. Start by tackling the biggest sources of energy waste — poor insulation, inefficient heating or cooling systems, and outdated lighting. Upgrading to LED fittings, improving roof or wall insulation, and adding smart HVAC controls can all have a noticeable impact on your score.

The recommendations report that comes with your certificate highlights which upgrades will give the best return. Some improvements cost very little but pay back fast, such as draught-proofing or installing timers and occupancy sensors. For older properties, more substantial upgrades like boiler replacements or glazing improvements might be worth considering, especially if you’re planning to sell or lease the building soon.

Improving your Commercial EPC rating can cut running costs, reduce carbon emissions and help meet Minimum Energy Efficiency Standards (MEES) if you rent the property out. A higher grade also makes your building more appealing to tenants and investors.
