Putting up a fence in your garden can seem like a simple job, but it is worth checking the basics before you start. A new fence can improve privacy, security and the appearance of your property, but it can also create problems if it is built in the wrong place, exceeds permitted height limits or affects a neighbour’s boundary.

In many UK domestic situations, you do not need your neighbour’s permission to install a fence if it is entirely on your land and complies with planning rules. However, that does not mean you should ignore your neighbour. Boundary work is one of the most common causes of disputes, and a brief conversation before installation can prevent a lot of trouble later.

This guide explains when you may be able to put up a fence without neighbour consent, when permission or checks may be needed, how fence height rules work, and how to approach the project in a way that protects both your property and neighbour relations.

Can I put up a fence without my neighbour’s permission?

In many cases, yes, provided the fence is installed entirely on your land, does not interfere with your neighbour’s property and stays within any relevant planning limits. If you are replacing or altering a fence that belongs to your neighbour, or building directly on the boundary in a way that affects them, you should not proceed without agreement.

The key questions are:

Who owns the existing fence or boundary feature?
Where is the legal boundary?
Will the new fence sit fully within your land?
Will the finished height comply with planning rules?
Are there any restrictions on your property?
Will digging affect neighbouring structures?
Will the work cause damage or access issues?

If the answer to any of these is unclear, check before starting. Moving a fence after installation is far more costly than planning properly at the beginning.

Check the boundary before installing a fence

The first step is to understand where the boundary sits. This is not always as obvious as it looks. Existing fences may not follow the exact legal boundary, especially on older properties where boundaries have changed over time.

Property title plans can help, but they often show general boundaries rather than precise measurements to the centimetre. In some cases, the deeds or transfer documents may include more information about boundary responsibility, but not always.

Before installing a new fence, check:

Your title plan
Any property deeds or transfer documents
Previous boundary agreements
Existing fence positions
Neighbouring structures
Old posts, walls or markers
Any history of boundary disputes

If the boundary position is uncertain, it may be worth taking advice from a boundary surveyor or property professional before work begins.

Fence ownership is not always obvious

Many people believe that the side of the garden or the position of fence posts proves ownership. This is not a reliable rule. The idea that you always own the fence on the left or right is a common misconception.

Fence ownership may be set out in property documents, but sometimes it is not recorded clearly. A fence may have been installed by a previous owner, paid for jointly or moved over time.

If you are unsure who owns the existing fence, avoid removing, altering or attaching anything to it until the position is clearer.

Can I replace an old fence without asking my neighbour?

If the fence is yours and sits on your land, you can usually replace it, subject to planning rules and any property restrictions. However, it is still sensible to tell your neighbour what you plan to do.

If the fence belongs to your neighbour, you should not remove or replace it without their permission. Even if it looks old, damaged or unattractive from your side, it may still be their property.

If the fence is shared or responsibility is unclear, discuss the matter before any work begins. A short conversation can avoid a dispute over cost, position, style or height.

Can I build a fence just inside my boundary?

You may be able to build a fence just inside your own boundary without using or altering your neighbour’s fence. This can be useful when the neighbour owns the existing boundary and you want your own privacy or security.

However, this approach needs care. You should make sure the fence is fully within your land, does not damage the neighbour’s fence and does not create maintenance problems between the two structures.

If the gap between fences is too narrow, weeds, leaves and moisture can build up. It may also become difficult to paint, repair or inspect either fence.

Can I attach fence panels, trellis or screening to my neighbour’s fence?

No, not without permission. If the fence belongs to your neighbour, you should not attach fence panels, trellis panels, screening, plant wires, lights, hooks or brackets to it without their agreement.

Even small fixings can cause damage or create future maintenance issues. Trellis and climbing plants can add weight and wind load. Screening can make a fence more vulnerable in strong winds.

If you want extra privacy on your side, use your own posts and supports rather than relying on the neighbour’s fence.

Do I need planning permission for a fence?

Many domestic fences can be installed without planning permission if they meet permitted development rules. As a general guide, a fence, wall or gate should not exceed 1 metre in height if it is next to a highway used by vehicles, including the footpath of such a highway. Elsewhere, the usual limit is 2 metres.

Planning permission may be needed if the fence exceeds those limits or if special conditions apply. Always check if your property is listed, in a conservation area, affected by an Article 4 direction or subject to planning conditions.

The finished height matters. Fence panels, gravel boards, trellis toppers and capping can all add to the overall height.

Fence height at the front of a property

Front garden fencing is usually lower than rear garden fencing. Low picket fence panels, decorative fence panels and open boundaries are common because they define the property without blocking visibility.

If the fence is next to a highway used by vehicles, including the footpath of that highway, the usual permitted development limit is 1 metre. This is particularly important near driveways, junctions, footpaths and roads.

A tall front fence may need planning permission and may also affect visibility for drivers and pedestrians.

Fence height at the rear or side of a property

Rear and side garden fences are often taller because privacy and security are more important. In many domestic rear gardens, 1.8m fence panels are common. Fences up to 2m may fall within the usual permitted development height limit where they are not next to a relevant highway, but you should still check the circumstances.

If you add a gravel board beneath a 1.8m panel, the finished height may be higher than 1.8m. If you add trellis on top, it may exceed 2m.

Always measure the total height from ground level, not just the panel size.

Does trellis count towards fence height?

Yes. Trellis added to the top of a fence should be counted as part of the total boundary height. A fence panel, gravel board and trellis topper all contribute to the finished height.

Trellis can feel lighter than a solid panel because it allows light and air through, but it still increases the structure. If the overall height exceeds permitted limits, planning permission may be needed.

Before adding fence topper trellis, check the post strength as well. Extra height increases wind load, especially once climbing plants grow through it.

Do gravel boards count towards fence height?

Yes. Gravel boards form part of the fence structure. A 1.8m fence panel on a 150mm gravel board has a finished height of around 1.95m before any capping or trellis is added.

This matters when planning a privacy fence. Gravel boards are useful because they protect fence panels from ground moisture, but they still add to the total height.

Listed buildings, conservation areas and special restrictions

Some properties have additional restrictions. If your home is listed, within the curtilage of a listed building or affected by a conservation area, you may need consent or planning permission for work that would be straightforward elsewhere.

Planning conditions or Article 4 directions can also remove normal permitted development rights. These restrictions are not always obvious, especially if you have recently moved into the property.

Check before starting if:

The property is listed
The property is in a conservation area
The boundary adjoins a listed building
Previous planning conditions apply
The fence is near a road or public footpath
You want a fence above the usual height limits

Does the Party Wall Act apply to fences?

The Party Wall etc. Act 1996 does not apply to every ordinary garden fence installation. However, it can become relevant where work involves building on or at the boundary, working on a party wall or party structure, or excavating near and below the foundation level of a neighbouring building or structure.

For a simple fence panel replacement, the Act may not be relevant. For more substantial boundary works, walls, deep foundations or excavation close to neighbouring structures, you should check whether notice is required.

If you are unsure, get proper advice before digging or building at the boundary.

Do I need to tell my neighbour before installing a fence?

You may not always be legally required to tell your neighbour, but it is usually wise. Fences sit where properties meet, so changes can affect both sides visually and practically.

Letting your neighbour know can help avoid disagreements about:

Fence position
Ownership
Height
Style
Colour
Access during installation
Disposal of the old fence
Plants growing through the boundary
Potential damage to their garden

A polite discussion does not mean you are giving up your rights. It simply reduces the risk of misunderstanding.

How to speak to a neighbour about a new fence

Keep the conversation practical and calm. Explain what you want to do, where the fence will go and when the work may happen.

Useful points to cover include:

Why you want to install or replace the fence
Whether it is on your side of the boundary
The proposed height
The type of fence panels
Whether posts and gravel boards will be used
How long the work may take
Whether access to their side is needed
How plants or existing features will be protected

If the fence benefits both properties, the neighbour may be willing to discuss shared costs, but do not assume this.

Can I ask my neighbour to pay for a fence?

You can ask, but your neighbour may not be obliged to contribute unless there is a clear legal or contractual responsibility. Boundary responsibility can depend on property documents, agreements or specific circumstances.

If the fence is yours and you choose to replace it, you should normally expect to pay for it yourself unless the neighbour agrees otherwise.

If a fence is shared or responsibility is unclear, discuss it carefully and put any cost agreement in writing.

What if my neighbour refuses to replace a damaged fence?

If the fence belongs to your neighbour, you cannot usually force them to replace it simply because you dislike its condition, unless there is a specific legal obligation or safety issue.

If privacy is the main concern, one option is to install your own fence or screening on your side of the boundary. This should be fully within your land and installed without damaging the existing fence.

If the fence is dangerous, leaning into your property or causing damage, seek advice before taking action.

Can my neighbour object to my new fence?

A neighbour can raise concerns if they believe the fence is on their land, exceeds planning limits, blocks light, affects access, damages their property or breaches an agreement. Whether their objection prevents the work depends on the facts.

Even where you are entitled to install the fence, disputes can become stressful and expensive. It is better to deal with concerns before work begins than after the fence is up.

What if a boundary dispute starts?

If a dispute starts, avoid making the situation worse. Do not remove a neighbour’s fence, move boundary markers or continue building if there is a serious disagreement about land ownership.

Steps to consider include:

Pause the work if necessary
Review title documents
Gather photos and records
Speak calmly with the neighbour
Confirm points in writing
Use mediation if discussion fails
Seek professional advice for serious disputes

Legal action should usually be a last resort. Boundary disputes can cost far more than the fence itself.

Choosing the right fence type

Once the legal and neighbour issues are clear, choose a fence that suits the property. The right fence depends on privacy, security, budget, wind exposure, maintenance and appearance.

Common options include:

Closeboard fence panels for strong privacy
Lap fence panels for a traditional budget-friendly boundary
Slatted fence panels for a modern look
Hit and miss fence panels for airflow and wind resistance
Picket fence panels for front gardens
Decorative fence panels for feature boundaries
Trellis panels for planting and lighter screening

For most rear garden privacy, full-height fence panels with strong posts and gravel boards are a common solution.

Choosing fence posts

Fence posts are critical to the strength of the fence. A good panel fixed to a weak post will not last well.

Main choices include timber fence posts and concrete fence posts.

Timber posts have a natural appearance and are easier to cut and work with. Concrete posts are heavier but durable and low maintenance. The right choice depends on the fence style, budget, ground conditions and appearance you want.

For taller fences, exposed gardens and heavier panels, post strength is especially important.

Using gravel boards

Gravel boards sit at the bottom of the fence and help protect fence panels from soil, splashback and damp. They can also close gaps at the base of the fence, which may help with pets and overall appearance.

Wooden gravel boards blend well with timber fencing. Concrete gravel boards are heavier but durable and resistant to ground moisture.

Remember that gravel boards add to the finished fence height, so include them in your measurements.

Can I install fencing myself?

Many homeowners install garden fencing themselves, especially for short, straightforward runs. However, fencing requires accurate measuring, digging, levelling and post setting.

DIY installation may be suitable if:

The boundary is clear
The ground is level
The fence run is short
You are using manageable materials
No major old concrete needs removing
No boundary dispute exists
You have the right tools and help

Professional installation may be better for long runs, slopes, concrete posts, heavy gravel boards, difficult access, gates or uncertain boundaries.

Access and working near the boundary

Fence installation often needs space to work. If access is only possible from your neighbour’s side, ask permission before entering their garden. Do not assume you can go onto their land to install or paint the fence.

If access is refused, you may need to adapt the installation method or work entirely from your side.

Protect neighbouring plants, lawns, patios and garden features during work. Accidental damage can quickly sour relations.

Removing the old fence

If the old fence is yours, remove it carefully and dispose of it properly. Treated timber should not be burned in a garden. Old posts, concrete, screws and nails should be handled safely.

If the old fence is shared or belongs to the neighbour, do not remove it without agreement.

Before removal, take photos. This can be helpful if questions arise about the original position or condition.

Installing a fence near trees and hedges

Trees, hedges and large shrubs can complicate fence installation. Roots may affect post holes, and cutting back vegetation may raise neighbour or wildlife issues.

Before work begins, check:

Whether roots will obstruct post holes
Whether branches overhang the boundary
Whether hedges contain nesting birds
Whether the tree is protected
Whether the fence will trap vegetation
Whether future maintenance will be possible

Do not damage protected trees. If in doubt, check before cutting or digging.

Fence installation and wildlife

Boundary work can affect wildlife. Hedgehogs, birds, insects and other animals may use fence lines, hedges and overgrown corners.

When replacing fencing, consider:

Checking for nesting birds before cutting dense vegetation
Providing hedgehog access where safe
Avoiding loose netting that can trap wildlife
Keeping ponds and holes safe during work
Removing old materials promptly
Leaving some planting for habitat where practical

Gravel boards with hedgehog holes can be useful where you want a tidy fence base while still allowing wildlife movement.

Common mistakes when putting up a fence

Many fence problems happen because the project starts before the legal and practical checks are complete.

Common mistakes include:

Assuming the boundary position without checking
Removing a neighbour’s fence without permission
Building partly on a neighbour’s land
Forgetting planning height limits
Ignoring listed building or conservation area restrictions
Adding trellis without measuring total height
Using weak posts for tall panels
Not discussing access with neighbours
Leaving old concrete in the way of new posts
Failing to check for underground services
Letting disputes escalate instead of pausing

A fence is a boundary feature, so small errors can become sensitive quickly.

Fence permission checklist

Use this checklist before installing a new fence:

Check who owns the existing fence
Review your title plan and property documents
Confirm the proposed fence is on your land
Check the finished height from ground level
Include gravel boards and trellis in the total height
Check whether the fence is next to a highway
Check for listed building or conservation area restrictions
Consider whether the Party Wall Act may apply
Speak to your neighbour before work begins
Agree access if needed
Choose suitable fence panels and posts
Check for underground services before digging
Plan waste removal
Keep a written record of any agreements

Frequently asked questions

Do I need my neighbour’s permission to put up a fence?

If the fence is entirely on your land and complies with planning rules, you may not need your neighbour’s permission. However, you should not alter, remove or attach anything to a fence that belongs to your neighbour without their agreement.

Can I put a fence on the boundary line?

This depends on ownership, agreement and the exact boundary position. If you are building directly on a shared boundary, discuss it with your neighbour and take advice if the position is unclear.

Can I build a fence inside my boundary?

Often yes, provided it is fully on your land, complies with planning rules and does not damage neighbouring property. Leave enough space for maintenance where possible.

How high can my fence be without planning permission?

In many domestic situations, the usual permitted height is 1 metre next to a highway used by vehicles, including the footpath of such a highway, or 2 metres elsewhere. Exceptions can apply, so check if your property is listed, in a restricted area or subject to planning conditions.

Does my neighbour have to pay for half the fence?

Not necessarily. Your neighbour only has to contribute if there is a clear responsibility or they agree to share the cost. Do not assume costs will be shared without agreement.

Can I remove my neighbour’s fence if it is falling down?

No, not without permission or proper legal grounds. If the fence is dangerous or causing damage, seek advice before taking action.

Can I attach trellis to my neighbour’s fence?

Not without permission. Trellis adds weight, wind load and fixings to the fence. Use your own posts or a free-standing trellis if permission is not given.

Does the Party Wall Act apply to garden fences?

It may not apply to a simple fence panel replacement, but it can apply to some building work on or at a boundary and to certain excavations near neighbouring structures. Check before substantial boundary work.

What should I do if my neighbour objects?

Pause and clarify the issue. Check documents, discuss the concern calmly and consider mediation or professional advice if the disagreement is serious.

Should I tell my neighbour before replacing my fence?

Yes, it is sensible. Even where permission is not required, telling your neighbour helps avoid misunderstandings about access, height, style and boundary position.

Final thoughts

You may be able to put up a fence without your neighbour’s permission if it is on your land, within permitted height limits and not subject to special restrictions. However, boundary work should never be rushed. Check ownership, position, height, planning rules and access before ordering materials or removing an old fence.

Neighbour permission is not always a legal requirement, but neighbour communication is usually good practice. A simple discussion can prevent disputes and may help agree style, timing or shared costs where both properties benefit.

A well-planned fence should provide privacy, security and a clear boundary without creating avoidable legal or neighbour problems. Take the time to check first, choose suitable fence panels, posts and gravel boards, and install the fence carefully so it stands straight, lasts well and keeps relations intact.
