How High Can a Fence Be Without Planning Permission UK

How High Can a Fence Be Without Planning Permission UK?

Fences play an important role in providing privacy, security and clear boundaries between properties. Many homeowners consider increasing the height of a fence to make their garden more private or to improve safety, but it is essential to understand the planning rules before making changes. The maximum height of a fence without planning permission is set out under permitted development rights, which apply to most houses in the UK.

General Rules for Fence Heights

Under permitted development rights, you can usually erect or alter a fence without planning permission if it does not exceed two metres in height. This applies to fences in back gardens, side boundaries and most areas not directly facing a highway. A fence of up to two metres provides sufficient privacy and security without being considered visually intrusive to neighbours or the wider area.

Where the fence is adjacent to a highway used by vehicles or a footpath next to a highway, the maximum height without planning permission is reduced to one metre. This lower limit is designed to protect visibility for drivers and pedestrians, ensuring road safety is not compromised by tall boundary treatments.

When Planning Permission Is Required

Planning permission is required if you want to build a fence higher than two metres in a back or side garden, or higher than one metre where it adjoins a highway. Permission is also required if your property is listed, as listed building consent will be necessary for almost any alteration to boundaries or features. In conservation areas or areas of outstanding natural beauty, local councils may impose stricter controls, meaning planning consent may be needed even for fences within standard limits.

Flats and maisonettes do not benefit from permitted development rights in the same way as houses, so planning permission may be required for new boundary fences. If your property already has planning conditions attached that restrict alterations, these may also remove the right to put up a fence without permission.

Building Regulations and Other Considerations

Building regulations do not generally apply to fences, unless they form part of a wall or structure that requires additional support. However, safety and stability remain important, and a fence should be constructed to withstand wind loads and general wear. If the fence is close to a neighbour’s boundary, the Party Wall Act may also apply if substantial foundations or walls are involved.

Practical considerations include how the fence height will affect your neighbours. A fence at the maximum permitted height of two metres may block light or feel overbearing in small gardens. Talking to neighbours before making changes can help avoid disputes. It is also important to ensure that the boundary you intend to fence is legally yours by checking property deeds or title plans.

Costs of Installing a Fence

The cost of putting up a new fence varies depending on materials, size and labour. A simple timber panel fence at around two metres high might cost £70 to £120 per panel installed, while higher-quality closeboard or composite fencing can cost more. Labour costs also depend on ground conditions and whether old fencing needs to be removed. For a typical semi detached garden, the cost of a new fence is often between £1,200 and £3,000, depending on length and finish.

Local Authority Guidance

Because local councils can impose specific restrictions, especially in conservation areas or housing developments with planning conditions, it is always wise to confirm before starting work. If you want certainty, you can apply for a lawful development certificate, which provides written confirmation that your proposed fence complies with permitted development rules.

Summary

In the UK, you can usually build or replace a fence up to two metres high without planning permission in back or side gardens, and up to one metre high where the fence adjoins a highway. Taller fences or those in conservation areas, listed properties or restricted developments will require planning consent. Building regulations do not normally apply, but safety and neighbourly considerations should always be taken into account. Checking with your local authority before beginning work will ensure your project is compliant and avoids future disputes.
