Short answer

Most neighbour disputes in England and Wales are settled by talking, then by formal routes. Party wall work needs written notice of one or two months under the Party Wall etc. Act 1996. Councils handle high hedge and noise complaints and planning enforcement. Boundary disputes go to HM Land Registry, the tribunal or court.

How do you resolve a boundary dispute with a neighbour?

In England and Wales there is usually no exact record of where a boundary lies. Land Registry title plans show general boundaries only, so the line on the plan is not conclusive. Start by gathering your title documents, the deeds and plans from when the land was first sold, old photos, and evidence of where fences and walls have stood.

• Boundary agreement: you and your neighbour can record an agreed line in writing and, if you wish, register it.
• Determined boundary: you can apply to HM Land Registry to record the exact boundary with a detailed surveyed plan. If your neighbour objects and the objection cannot be resolved, it is referred to the First-tier Tribunal (Property Chamber).
• Court: a county court claim can decide the boundary and trespass, but legal costs can quickly exceed the value of the land in dispute.

Do I need a party wall agreement?

If you plan work covered by the Party Wall etc. Act 1996, you must serve written notice on the adjoining owner. Covered work includes:

• Work to a shared party wall, such as cutting in beams for a loft conversion: at least two months' notice.
• Building a new wall on or at the boundary line: at least one month's notice.
• Excavating within three metres of a neighbour's building and deeper than its foundations, or within six metres in some cases: at least one month's notice.

Your neighbour has 14 days to consent. If they do not reply in writing within 14 days, a dispute is treated as having arisen. Surveyors (one agreed surveyor, or one each) then make a party wall award setting out how the work is done, and the building owner usually pays their fees. A party structure notice lapses if the work has not started within 12 months.

What can you do about overhanging trees and high hedges?

You can cut back branches and roots that cross onto your land, but only up to the boundary. Going further, or damaging the tree, risks a claim against you. If a tree has a tree preservation order or is in a conservation area, you need the council's consent first.

Under Part 8 of the Anti-social Behaviour Act 2003, you can complain to your council about a high hedge if it is made up of two or more mostly evergreen or semi-evergreen trees or shrubs, is over two metres tall, and affects your reasonable enjoyment of your home or garden. You must try to settle it with your neighbour first, and the council may charge a fee. It can order the hedge to be reduced.

What are your rights against noisy neighbours?

Keep a diary of dates, times and the type of noise, and record it if you can. If talking does not work, complain to your council. Under section 79 of the Environmental Protection Act 1990, the council must investigate noise that may be a statutory nuisance and, if it agrees, serve an abatement notice. Breaching the notice is a criminal offence. If the neighbour rents, you can also raise it with their landlord. You can also bring your own private nuisance claim for an injunction or damages, although this is usually a last resort because of the cost.

Do you have a right to light?

There is no automatic right to a view or to sunlight in a garden. A right to light over a particular window can arise, usually after 20 years of uninterrupted use, or through a deed. It protects enough light for ordinary use of the room, not all existing light. If a new building would seriously reduce light to a protected window, a court can award damages or, in some cases, an injunction. Act early: courts are less willing to order demolition once a building is up. If you are the one building, check for neighbouring windows that may have acquired a right to light before you finalise your plans.

How do you object to a neighbour's planning application or extension?

Check whether the work needs planning permission at all. Many householder extensions are permitted development and do not need an application, although rules differ between England and Wales and are restricted for listed buildings, flats and conservation areas. A lawful development certificate from the council confirms that existing or proposed work is lawful.

If an application is made, the council publicises it and you can usually comment within 21 days. Focus on planning issues such as loss of light, overlooking, design and parking, not property values. Only the applicant can appeal a refusal. In England, for applications made on or after 1 April 2026, most appeals are decided on the application papers and neighbours cannot add new comments at the appeal stage, so your objection to the council matters.

What if someone builds without planning permission?

Report it to your council's planning enforcement team. The council can serve an enforcement notice requiring the work to be undone. The person served can appeal, but must do so before the notice takes effect, which is at least 28 days after service. In England, for breaches on or after 25 April 2024, the council generally has 10 years to take enforcement action. In Wales, the four year limit still applies to unauthorised building works.

What are the key deadlines and time limits?

These are the main time limits for property and planning disputes in England and Wales:

• Party wall notice: two months for party structure work, one month for new boundary walls and excavations.
• Neighbour's response to a party wall notice: 14 days, or a dispute is deemed to arise.
• Party structure notice lapses if work has not begun within 12 months.
• Comments on a planning application: usually 21 days from publicity.
• Applicant's appeal against refusal: 12 weeks for householder applications, six months for most other planning applications (England and Wales).
• Enforcement notice appeal: before the notice takes effect (at least 28 days after service).
• Planning enforcement in England: generally 10 years for breaches from 25 April 2024.

What should you do next?

1. Gather evidence: title registers and plans from HM Land Registry, older deeds, photos, a noise diary, or the planning application reference.
2. Talk to your neighbour and then write a calm letter setting out the problem and what you want. Keep copies.
3. Use the formal route for your issue: a party wall notice, a council high hedge or noise complaint, a planning objection, or a determined boundary application.
4. Check deadlines before you act, especially the 21 day planning comment window and party wall notice periods.
5. Ask Libra about your situation, for example whether your neighbour's extension needs permission or how to respond to a party wall notice.

Frequently asked questions

Who owns the fence between two properties?

There is often no record. Your title deeds or original conveyance may say who must maintain a boundary fence, sometimes with T marks on the plan. If the documents are silent, there is no general rule, and ownership is worked out from the evidence.

Can my neighbour build an extension without telling me?

Often yes. Many single storey rear extensions are permitted development and need no application, though in England larger ones need prior approval, where neighbours are notified. If the work involves a shared wall or nearby excavation, your neighbour must also serve a party wall notice.

What happens if my neighbour ignores a party wall notice?

If they do not give written consent within 14 days, a dispute is treated as having arisen. The building owner can then appoint a surveyor. If the neighbour still fails to appoint one within 10 days of a further request, the building owner can appoint one on their behalf.

Can I cut down my neighbour's overhanging tree?

You can trim branches and roots only up to the boundary, and you should not damage the tree as a whole. Check with the council first for tree preservation orders or conservation areas. Offer the cuttings back to your neighbour, as they belong to them.

Can I appeal if the council approves my neighbour's application?

No. There is no third party right of appeal in England or Wales. The only challenge is a judicial review in the High Court, which must be brought promptly and within six weeks for planning decisions, and only on legal grounds such as a flawed process.

How long does a council have to enforce planning rules?

In England, for breaches from 25 April 2024 the limit is generally 10 years. Building works completed before that date keep the old four year limit. In Wales, unauthorised building works generally become immune after four years and most other breaches after 10.

Can I build a shed or garden office without planning permission?

Often yes under permitted development. The outbuilding must be single storey, no higher than 2.5 metres if within two metres of a boundary, and otherwise up to 4 metres with a dual pitched roof or 3 metres for other roofs. It cannot sit forward of the house and must not cover over half your garden. Listed buildings and flats have tighter rules.

How high can my neighbour's fence be without planning permission?

The general limit is 2 metres for a fence, wall or gate, and 1 metre next to a highway used by vehicles. Listed buildings and some protected areas have stricter rules. A fence built higher than permitted may need planning permission, so check with the council before building or complaining.

Who pays if my neighbour's tree roots damage my house?

The tree owner can be liable in nuisance or negligence if the damage was reasonably foreseeable. Tell your neighbour in writing with photos and a surveyor's report, and notify your buildings insurer promptly. Do not cut roots or the tree without advice, as protected trees or conservation areas can carry penalties.

Can my neighbour point a CCTV camera at my garden?

Cameras on a home are allowed, but if one captures your garden, windows or the street beyond their boundary, data protection law can apply and they may need to justify it. Raise it politely first, then write to them. You can then complain to the Information Commissioner's Office or consider a nuisance claim.

Can I stop my neighbour having bonfires?

There is no general ban on garden bonfires, but smoke that unreasonably interferes with your home can be a statutory nuisance under the Environmental Protection Act 1990. Keep a dated log and report it to your local council's environmental health team, which can serve an abatement notice.

Can I claim a strip of my neighbour's land after using it for years?

Possibly, but it is hard. For registered land you generally need 10 years of continuous possession without the owner's permission and must apply to the Land Registry, which tells the owner and lets them object. Unregistered land has a 12 year period. Permission or a boundary agreement can defeat a claim.
