If you are replacing or building a garden fence, check the legal limits before ordering your materials. The main garden fence height rules UK homeowners need to know are the two-metre general limit and the lower one-metre limit beside a highway. These rules sound simple, but the position of your boundary, local restrictions and neighbouring land levels can affect your plans.

This guide gives practical general information for properties in England. Planning rules can differ in Wales, Scotland and Northern Ireland, and individual properties may have extra restrictions. Always confirm uncertain cases with your local planning authority before starting work.

What is the two-metre fence rule?

Under permitted development rights in England, you can usually put up, replace or alter a fence, wall or gate without making a planning application if it is no more than two metres high. This normally applies to rear and side garden boundaries that are not next to a highway used by vehicles.

The limit applies to the total height of the structure. That means you should include gravel boards, trellis and decorative toppers rather than measuring only the main panel. For example, a panel mounted above a concrete gravel board may exceed two metres overall even when the panel itself is below the limit.

If your proposed fence will be higher than two metres, you will normally need planning permission. Do not assume an existing tall fence automatically gives you permission to replace it at the same height. It could have specific consent, may pre-date current controls or may never have been authorised.

Standard-sized fence panels, posts and boards can be combined in different ways, so work out the complete installed height before buying. K C Fencing and Timber Ltd supplies materials but does not fit or install fencing.

How high can a front garden fence be?

A fence, wall or gate beside a highway used by vehicles can generally be no more than one metre high without planning permission. This frequently affects front gardens, but the rule is based on proximity to the highway rather than simply whether the fence is at the front of your home.

For planning purposes, the highway may include the road, pavement or verge. A side boundary next to a road can therefore fall under the one-metre rule too. A front boundary that is set well back may need closer assessment by the council.

You will normally need planning permission if you want a structure above one metre next to a vehicle highway. This restriction helps protect visibility and road safety, especially near driveways, junctions and bends. Your council's highways team may also raise concerns if a fence blocks a driver's view when leaving a drive.

Do not rely on the height of other fences in your street. Those properties may have permission, different boundary positions or different planning restrictions.

When might planning permission be required?

You should contact your local planning authority if:

Your proposed rear or side fence will exceed two metres in total height.
Your proposed fence will exceed one metre beside a highway used by vehicles.
Your property is listed or the fence falls within the curtilage of a listed building.
The site is in a conservation area or is affected by an Article 4 direction.
A planning condition removed permitted development rights when the property was built.
You want to alter a boundary wall or railing with historic or protected status.
You are unsure how the rules apply to sloping or uneven land.

Listed building consent may be required separately from planning permission. Conservation area controls can also apply to the demolition of certain walls, fences or gates. Check both the planning history of your property and any restrictions shown in your deeds.

Planning permission is separate from private legal restrictions. A council decision does not override a restrictive covenant, and permission does not give you the right to build on a neighbour's land.

How is fence height measured?

Fence height is generally measured from the existing ground level immediately beside the structure. Where land slopes or neighbouring gardens sit at different levels, the correct measurement may be less obvious. Raised beds, decking or newly added soil should not be treated as an easy way to increase the permitted height.

Ask your council to confirm its approach if a proposed fence runs along a steep slope or sits beside land at another level. Provide photographs, measurements and a simple plan so the officer can understand the site.

Remember to calculate every component. A typical system might include a gravel board, panel and trellis. Concrete posts may stand slightly above the panel, and post caps can add further height. You can use our fence calculator to estimate materials, but planning compliance remains your responsibility.

Who is responsible for a boundary fence?

There is no general rule that you own the fence on the left or the right when looking down your garden. Responsibility should be established from reliable property documents, not local sayings.

Start by checking your title register, title plan, conveyance or transfer documents. A plan may use inward-facing T marks to show responsibility, while an H mark can indicate a shared boundary feature. However, not every title contains these marks, and title plans usually show general rather than exact boundaries.

Responsibility for a boundary does not always create an obligation to maintain a fence. Your deeds might contain a duty to maintain a particular structure, but otherwise you may not be able to force a neighbour to repair or replace it simply because you consider it their side.

Before removing a fence, speak to your neighbour. Confirm who owns it, where the legal boundary lies and whether plants, sheds or cables are attached. If ownership or the boundary position is disputed, obtain independent legal advice or advice from a qualified boundary surveyor before doing any work.

Can you put up your own fence inside the boundary?

You may be able to build a separate fence entirely on your own land, subject to planning controls, deeds and other legal restrictions. This can be useful where a neighbour does not want to replace their fence. Leave enough room to avoid posts, foundations or concrete crossing the legal boundary.

You must not attach panels or supports to a neighbour's posts or wall without permission. Take care around underground utilities and avoid damaging tree roots. If the work requires access to neighbouring land, agree this with the owner in advance rather than assuming you have an automatic right to enter.

A clear conversation often prevents a disagreement. You may wish to record an agreement about the fence position, ownership and future maintenance in writing, particularly if costs are being shared.

Choosing suitable fencing materials

Once you have confirmed the permitted height and boundary position, choose components that suit the location. Exposed gardens generally need strong posts and secure fixings. Concrete posts offer a durable option, while gravel boards help keep timber panels away from wet ground.

Measure the full run at ground level and note corners, changes in direction and slopes. Check several bay widths rather than assuming every existing gap is identical. Also decide whether you need standard panels, timber rails, posts, boards, fittings or a gate.
