According to GOV.UK, you are legally required to have an EPC in the following circumstances:

- Renting a property: Landlords must provide tenants with an EPC. Rental properties must meet a minimum E rating.
- Building a new property: A predicted EPC is produced at the design stage, and an as-built EPC on completion.
- Applying for grants: Some government grant schemes require a current EPC to assess eligibility.
Penalty for Non-Compliance
According to GOV.UK, failing to provide an EPC when required can result in a penalty of up to £5,000 for commercial properties or £200 for domestic properties.
