What an EPC for a non-dwelling contains
In addition to the asset ratings, EPCs must convey several other key pieces of information:
Reference information
This includes the unique certificate reference number (as stored in the central register) the date of issue of the certificate and when it is valid until.
Energy assessor details
This includes the assessor’s name, accreditation number, company name (or trading name if self employed) and accreditation scheme.
Information on how to complain or how to confirm that the certificate is genuine
The certificate will provide information on how to register a complaint about an unsatisfactory EPC and how to check the certificate is authentic. The certificate is accompanied by a report which includes cost-effective  recommendations to improve the energy ratings. For each improvement indicative paybacks are listed.
