Do I Need Planning Permission for a Fence?

Fences, walls, and gates are among the simplest improvements you can make to a property. But there are clear height limits, and getting them wrong can lead to enforcement action.

The Basic Rule: Height Limits

Under permitted development, you can erect a fence, wall, or gate without planning permission if:

It's no more than 2 metres high (measured from ground level on the highest side)

If it's next to a road used by vehicles, the limit drops to 1 metre

That's it. Those are the two numbers you need to remember.

The "Adjacent to a Highway" Rule

This is where most people get caught out. The 1-metre limit applies to any fence or wall that is adjacent to a highway used by vehicular traffic. "Adjacent" means next to, bordering, or within the boundary alongside the road.

This includes:

Front garden fences along a road

Side fences where your garden borders a road (including on corner plots)

Fences along public footpaths that are also roads (most pavements are technically part of the highway)

It does not include:

Back garden fences that don't border any road

Fences alongside a purely pedestrian path with no vehicle access

Corner plots are particularly affected - you may have road frontage on two sides, meaning the 1-metre limit applies to both.

When You Need Planning Permission

1. Height Exceeds the Limits

Want a 2.5-metre fence for extra privacy? You need planning permission. Want a 1.8-metre fence along your front boundary? Planning permission.

2. Listed Buildings

If your home is listed, any new fence or wall within the curtilage (garden and grounds) may need listed building consent, especially if it affects the setting of the listed building. A modern panel fence in front of a Georgian townhouse is likely to be refused.

3. Conservation Areas

Many conservation areas have Article 4 Directions that remove permitted development rights for fences and walls. Even where permitted development still applies, councils often have policies about boundary treatments in conservation areas - for example, requiring hedges rather than close-boarded fences on front boundaries.

4. Planning Conditions

Some newer properties have conditions on their original planning permission that restrict fences. Common conditions include:

"No fence or wall shall be erected on the front boundary"

"Boundary treatments shall be as approved" (with a specific plan)

"No close-boarded fence above 1.2 metres on any boundary facing a public area"

Check the original planning permission for your property if it was built or significantly altered in the last 20 years.

Measuring Height Correctly

The 2-metre and 1-metre limits are measured from natural ground level - not from a raised flower bed, retaining wall, or patio that you've built. If you sit a 2-metre fence on top of a 0.5-metre retaining wall, the total height from ground level is 2.5 metres and you need planning permission.

This catches a lot of people on sloping sites. If the ground drops away, you measure from the higher side (the side where the fence looks shortest), but enforcement officers will usually assess from the public viewpoint.

Trellis on Top of a Fence

Adding trellis on top of a fence counts towards the total height. A 1.8-metre fence with a 0.3-metre trellis is a 2.1-metre structure and needs planning permission if it exceeds the limit.

There is no "trellis exemption" - this is a persistent myth. Trellis is included in the measurement regardless of whether it's open or closed.

Front Garden Fences and Hedges

Even though front fences over 1 metre need planning permission, hedges have no height limit under planning law. You can grow a 3-metre hedge in your front garden without planning permission (though the High Hedges Act 2005 gives neighbours the right to complain about hedges over 2 metres that affect their enjoyment of their property).

This means the practical choice for many homeowners is:

Plant a hedge for privacy (no permission needed)

Or apply for planning permission for a fence over 1 metre

Neighbour Disputes

Boundary fences are the most common cause of neighbour disputes. Key legal points:

You don't need your neighbour's permission to erect a fence on your side of the boundary

You cannot attach anything to your neighbour's fence without their permission

If the fence is exactly on the boundary, both parties own it jointly (unless deeds say otherwise)

There is no legal "right to a view" - your neighbour cannot object to a fence because it blocks their view, unless it blocks light to a habitable room window

Practical Steps

1. Measure from natural ground level - not from any raised feature 2. Check if your boundary is next to a road - remember the 1-metre limit 3. Check for Article 4 Directions if you're in a conservation area 4. Review your property's planning conditions for any fence restrictions 5. Talk to your neighbours - not legally required, but avoids disputes
