If an EPC has already been produced for a property, this EPC can be re-used for

future sales or rental of the property. EPCs are valid for 10 years from the date of their

production and can be re-used as many times as required within that period.

If a new EPC is lodged, this then becomes the only valid one. EPCs are not

invalidated by renovation works or improvements. However, a landlord or seller may

wish to obtain a new certificate to demonstrate the energy efficiency improvements to

potential tenants/ buyers.
