Which buildings need an EPC

An EPC is required when a building is built, rented or sold.
A building is defined as a structure with a roof and walls which uses energy to ‘condition an indoor climate’. This means it has heating, air conditioning or mechanical ventilation.
The building can either be a whole building or part of a building that has been designed or altered to be used separately. If a building is made up of separate units, each with its own heating system, each unit will need an EPC
