The Regulations state that.

If you are offering any accommodation for sale or let (this includes sub-letting) you will need to make an EPC available that reflects the energy performance of the accommodation on offer.

An EPC should be provided to a prospective buyer or tenant at the earliest opportunity and no later than when a viewing is conducted or when written information is provided about the building or in

any event before entering into a contract to sell or let.

As a seller or landlord you are responsible for ensuring

there is an EPC available for the accommodation

being sold or let even if an agent or another service

organisation is acting on your behalf.

You should therefore ensure any agents acting on your behalf

are complying with the Regulations.
