Registering EPCs

EPCs for non-dwellings are stored in a national register. The national register is the official place for the storage of all EPCs for non-dwellings and is the single source of EPC information for a building. Having a register helps to protect consumers. Those legitimately in possession of an EPC, ie building owners, tenants and their agents, can verify the authenticity of a certificate by checking it against the contents of the register.

Once EPCs have been registered they cannot be altered. However, EPCs that are in dispute may be annotated on the register to show that they are under investigation.

As data is kept on the register for 20 years, more than one EPC may be stored over a number of years for one building. An EPC may be valid for up to 10 years. If there are other certificates for the building on the register that are less than 10 years old only the most recent certificate will be valid.

Energy assessors (through their Accreditation Schemes) lodge each EPC after they produce it, and each is given a unique certificate reference number. Access to the database is restricted, so only those who have the unique reference number can access the certificate registered for a particular building.

The register is operated by Landmark Information Group Limited.
