Below is a clear, homeowner-friendly guide based on the key principles of the Party Wall etc. Act 1996 in England and Wales. It explains what a party wall is, what works trigger the Act, the notice timings, how agreement is reached, what happens if agreement cannot be reached, and the practical rules once works begin.
Overview: what the Party Wall etc. Act 1996 is for
If you want to carry out certain building works near or on a shared boundary or shared structure, you must follow the Party Wall etc. Act 1996. The Act applies in England and Wales.
The Act exists to do two things at the same time:
- allow a building owner to carry out lawful works, and
- protect neighbouring owners by ensuring they are informed and have a formal route to respond.
A common misunderstanding is that party wall procedure is the same as planning permission or building control. It is not. A project can have planning permission and still require party wall notices. Equally, building regulations approval does not remove party wall obligations.
(Scotland has different rules.)
What counts as a “party wall” or “party structure”?
Party walls
A party wall is a wall that relates to more than one owner. Common examples include the shared wall between two terraced or semi-detached homes.
In practical terms, party walls can include walls that:
- form part of a building and sit on the land of two owners, or
- do not form part of a building (such as certain shared masonry garden walls — not timber fences).
A useful rule of thumb:
- masonry boundary walls can be party walls,
- timber fences are generally not party wall matters.
Walls on one owner’s land used by another
There are also situations where a wall stands on one owner’s land but is used by neighbouring owners to separate their buildings. These can also fall within the Act’s concept of party wall arrangements.
Party structures
A “party structure” is a shared separating structure other than a wall, such as:
- floors or ceilings between flats,
- structural divisions between parts of buildings with different owners.
If you live in a converted building or block of flats, party wall procedure can apply to shared floors and walls between units.
Work you must tell your neighbour about
You must notify your neighbour if you intend to carry out works that fall into these main categories:
Building on or at the boundary of two properties
Examples include:
- building a new wall at the boundary,
- building up to the boundary line,
- proposing to build astride the boundary (usually requiring agreement).
Working on an existing party wall or party structure
Examples include:
- cutting into a party wall (for example to insert beams),
- making a party wall taller, shorter, or deeper,
- removing chimneys from a party wall,
- demolishing and rebuilding a party wall.
Excavating near the neighbour’s foundations
You must notify if you intend to dig below and near the foundation level of the adjoining owner’s property in circumstances covered by the Act. This is a common trigger for rear extensions and other foundation works near neighbouring buildings.
What you do not need to notify
You do not need to serve party wall notices for minor works such as:
- plastering,
- chasing for wiring or adding/replacing sockets,
- drilling to fit shelves or cupboards.
The dividing line is usually whether the work affects shared structures or notifiable excavation/boundary work—not ordinary internal decoration.
When and how to tell your neighbour
Notice timing
You must give notice between 2 months and 1 year before you plan to start certain types of work. In practice, the required notice period depends on the category of work:
- works to an existing party wall/party structure typically require a longer minimum lead time than excavation or boundary wall notices.
The most important practical point: do not serve late. Late service compresses the programme and creates neighbour pressure—pressure is what causes disagreement.
How to serve notice properly
A notice should:
- be served on the correct adjoining owner(s),
- explain what you plan to do,
- include the intended start date,
- be clear enough for a non-expert to understand the nature of the works.
Speak before you serve
You can (and usually should) speak to your neighbour before serving the notice. A calm, short explanation in advance often prevents the notice arriving as a surprise. The notice is still necessary, but the conversation often improves the response.
Keep agreements in writing
Any agreement you reach should be in writing. Informal chats do not replace written consent.
Reaching agreement with your neighbours
After notice is served, the neighbour can:
Consent in writing
If the neighbour consents in writing, the process can remain straightforward.
Refuse consent (dissent)
If the neighbour refuses consent, the dispute resolution process begins. This does not automatically stop your project, but it does change the route: surveyor involvement is usually required to conclude matters formally.
Serve a counter notice
A neighbour can serve a counter notice requesting additional works be done at the same time. In broad terms, if the additional works benefit them, they would typically pay for those elements.
The key response window
Neighbours must respond in writing within 14 days. If you receive a counter notice, you must respond to it too.
No response is not consent
One of the most important beginner points: you cannot assume silence means agreement. If they do not respond in time, the process moves forward as though a dispute exists for procedural purposes.
Who pays for what?
In most typical domestic situations:
- the building owner pays for the works they are initiating.
There are exceptions in principle:
- if work is required due to defects or lack of repair, cost sharing may be relevant; and
- if the neighbour requests additional works that benefit them, they typically pay for those additional elements.
If costs cannot be agreed, surveyors (once appointed) will set out who pays what as part of the formal process.
If you cannot agree: surveyors and the Party Wall Award
If agreement is not reached, surveyors must be appointed.
Surveyor appointment routes
- You can agree on one surveyor to act impartially, or
- each owner can appoint their own surveyor.
Those surveyors then agree the formal outcome.
What is a Party Wall Award?
A Party Wall Award is a legal document that typically sets out:
- what work is permitted under the Act,
- how and when it is to be carried out,
- what protections are required,
- who pays which costs (including surveyor fees).
You cannot act as your own surveyor
The Act does not allow an owner to act as the surveyor in their own matter.
If your neighbour does not appoint a surveyor
If your neighbour refuses or fails to appoint a surveyor after the proper steps, a surveyor can be appointed on their behalf so the process cannot be blocked by silence.
If you disagree with the Award
An Award can be appealed in the county court within 14 days of receiving it. Appeals are legal proceedings and should be approached carefully and promptly.
When works begin: your practical duties
When carrying out works under the Act, the building owner must:
- avoid causing unnecessary inconvenience, and
- protect the neighbour’s property from damage caused by the works, and
- fix or pay for damage caused.
These are practical obligations. They are not optional “good manners”; they are the behavioural expectations that help prevent disputes escalating.
Access to your neighbour’s property
Where the works fall under the Act and access is necessary, the Act provides for access in a controlled manner. In general terms:
- surveyors and workmen may require access during usual working hours to carry out the notifiable works,
- the adjoining owner must be given notice (often 14 days) except in an emergency.
Access should be managed professionally: defined areas, defined times, and proper supervision. Access disputes tend to arise when access is demanded late or vaguely.
