An Energy Performance Certificate (EPC) contains information about how energy is used in a home or a business premises, along with details of how much the energy used actually costs.
An EPC is required by law when a building is constructed, sold or put up for rent. If you are a landlord or homeowner and need to provide an EPC, you'll need to contact an accredited domestic energy assessor. They will carry out the assessment and produce the certificate.
