You do not need planning permission for most cases. A few things to consider: ﻿Development that is not permitted: • Development is not permitted in front of the house, or in front of a hypothetical line drawn through the front to the side boundary of land that surrounds the house. •If the pergola is erected more than 2m within the boundary of the dwelling house. Its height must not exceed 2.5 metres. Must not exceed 3 metres in height, in any other case. •It mustn't cover more than 50% of the area of your land. •It cannot be situated within the curtilage of a listed building •If your house is in a conservation area and your pergola is more than 20m from the house and greater than 10 square metres, you will need planning permission.
