Permitted Development rules for pergolas

Under Permitted Development in England, an outbuilding such as a pergola is allowed without planning permission if it sits behind the principal elevation of the house, does not exceed 2.5m in height if within 2m of any boundary, does not cover more than half of the garden area (counting all existing outbuildings), and is not used as a separate dwelling. Eaves must not exceed 2.5m if within 2m of a boundary.

When you do need planning permission

You will normally need to apply for planning permission if the structure exceeds 2.5m in height within 2m of a boundary, if your home is a listed building, if you live in a conservation area or AONB, if outbuildings already cover more than half the garden, or if the pergola is at the front of the house. Always check with your local planning authority.

Pergolas attached to the house

A pergola fixed to the house is treated like a rear extension. It must not extend beyond the rear wall by more than 3m (semi-detached or terraced) or 4m (detached) under standard Permitted Development, and the eaves height must not exceed 3m if within 2m of a boundary.
