When is Planning Permission Required for a Fence?

For many homeowners, updating garden boundaries is a quick way to improve privacy, security and kerb appeal. Whether you’re replacing an old fence, increasing its height or installing a brand-new boundary, it’s important to understand when planning permission is required. While some fencing projects fall under Permitted Development, others must meet strict rules, so knowing the difference can save time, cost and potential enforcement issues.

When is Planning Permission Required for a Fence?

Height, location and estate restrictions can all affect whether planning permission is required…

Fencing can be more complicated than many home improvements because it directly affects boundary lines shared with neighbours. While fences often fall under Permitted Development, several exceptions mean you must check the rules before starting work.

Fence height

You can usually put up a fence under 2 metres high without planning permission, but this limit drops to 1 metre when next to a highway. Installing a fence beyond the allowed height requires permission — even if the additional height comes from a trellis or climbing-plant supports.

Permitted Development rights may not apply if the property is listed, sits within the curtilage of a listed building, or is covered by an Article 4 Direction. Always speak with your neighbour in advance to avoid disputes.

Planning permission

You will need planning permission if your fence exceeds 2 metres in height or sits in an area originally designed with open-plan frontages. Local authorities can be strict, and unauthorised fences may need to be removed if permission is denied.

Other conditions

You do not need planning permission to remove, repair or maintain an existing fence — provided you don’t change its height. Hedges normally do not require planning permission unless restricted by a covenant or positioned where they reduce road safety sightlines.
