An EPC is required when a building is constructed, rented or sold. A building will need an EPC if it has a roof and walls and uses energy to ‘condition an indoor climate’. This means it has heating, air conditioning or mechanical ventilation. For example, a garden shed would not need an EPC if it doesn’t have any heating.
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.
