An Energy Performance Certificate (EPC) in the UK is generally valid for 10 years, but there are circumstances where an EPC may need to be updated or replaced rather than “extended.”
✅ Scenarios That Trigger a New EPC (Not an Extension):
Property Renovation or Extension:
If your building has undergone significant structural changes, such as a loft conversion, new insulation, or an added extension, a new EPC is required. These changes affect your building’s energy efficiency and must be reflected in an updated report.

If the building’s use changes from residential to commercial (or vice versa), a new EPC will be needed based on the new classification.Before Sale or Letting:
If you are selling or letting a property and the existing EPC is over 10 years old, or significant upgrades have occurred, a new EPC is strongly recommended.

Can You Extend an EPC?
Technically, EPCs cannot be “extended.” Once an EPC expires after 10 years, you must commission a new assessment by a certified energy assessor.
