If you are planning building work close to or on a boundary shared with your neighbour, you may need to serve a Party Wall Notice before work begins.
The notice is an important legal requirement under the Party Wall etc. Act 1996 applies to certain types of construction and excavation work in England and Wales.
Failing to serve the correct notice at the appropriate time can lead to disputes, delays, and potentially costly legal problems.
Whether you are planning an extension, loft conversion, excavation,n or work to a shared wall, understanding your obligations before construction begins can help protect both you and your neighbour.
At Charrette Law, we advise property owners and developers on party wall matters, including Party Wall Notices, Party Wall Agreements, and disputes arising under the Party Wall Act.
What Is a Party Wall Notice?
A Party Wall Notice is a formal written notice served on an affected adjoining owner to inform them that you intend to carry out certain types of building work covered by the Party Wall etc. Act 1996.
The Party Wall Act provides a legal framework for building works that could affect neighbouring properties or shared structures.
Depending on the nature of your proposed work, you may need to serve:
- Party structure notice
- Notice of adjacent excavation
- Line of junction notice
The correct notice will depend on the work you intend to carry out and the relationship between your proposed works and your neighbour’s property.
When Do You Need a Party Wall Notice?
Not every building project requires a Party Wall Notice.
However, you may need to serve notice if your proposed works fall within the scope of the Party Wall etc. Act 1996.
Common examples include:
Building on or Up to the Boundary
If you intend to build a new wall on or up to the line of junction between your property and your neighbour’s property, the Party Wall Act may apply.
For example, this could arise when constructing:
- A rear extension
- A side extension
- A new boundary wall
- A garden structure
- Other works close to the boundary
Work to an Existing Party Wall
A party wall is generally a wall that stands astride the boundary between two properties and is used by both owners.
If you intend to carry out certain works to an existing party wall, you may need to serve a Party Structure Notice.
Examples can include:
- Cutting into the party wall
- Raising the height of the party wall
- Extending or rebuilding the wall
- Carrying out structural work on the wall
Excavation Near a Neighbouring Property
You may also need to serve notice if you intend to excavate near your neighbour’s building.
This is particularly relevant where the excavation could extend below the level of your neighbour’s foundations.
Examples include excavation for:
- Foundations
- Basements
- Extensions
- Retaining structures
The precise requirements depend on the circumstances of the proposed excavation.
How Much Notice Do You Need to Give?
The required notice period depends on the type of work.
Under the Party Wall Act, the relevant periods can include:
- At least one month for certain building owner notices relating to party wall or boundary works.
- At least one month for certain adjacent excavation notices.
- At least two months for certain works to an existing party structure.
The precise notice requirement depends on the type of work being proposed.
This is why it is important not to rely on a generic Party Wall Notice template without checking which statutory notice applies to your project.
Who Should Receive the Party Wall Notice?
The notice generally needs to be served on the relevant adjoining owner or owners.
This can sometimes be more complicated than simply sending a letter to the person living next door.
An adjoining owner may include someone with a legal interest in the property, such as:
- A freeholder
- A leaseholder with a sufficient interest
- Other qualifying owners
There may also be more than one relevant adjoining owner.
Identifying the correct parties before serving notice is therefore an important part of the process.
What Should a Party Wall Notice Contain?
A valid notice should contain the relevant information required by the Party Wall Act and should clearly identify the proposed works.
Depending on the type of notice, this can include:
- The name and address of the building owner
- The address of the property where the work will take place
- The address or identification of the adjoining property
- A description of the proposed works
- The relevant statutory notice
- The proposed start date, where appropriate
- Information required by the relevant provisions of the Act
The wording and requirements can differ depending on the type of work.
For this reason, it is important that the notice is prepared carefully.
Can I Use a Party Wall Notice Template?
You can find Party Wall Notice templates online, but simply downloading a generic template does not necessarily mean that your notice is legally correct for your particular project.
A notice must accurately reflect:
- The proposed works
- The relevant section of the Party Wall Act
- The affected property
- The correct adjoining owner
- The applicable notice period
An incorrectly prepared or improperly served notice could create problems later.
If your project is substantial or your relationship with your neighbour is already difficult, obtaining professional advice before serving notice may be worthwhile.
How Is a Party Wall Notice Served?
The Party Wall Act contains requirements relating to the service of notices.
A notice should be served on the relevant adjoining owner in accordance with the applicable legal requirements.
It is important to retain evidence showing:
- What notice was served
- When it was served
- Who received it
- How it was served
This evidence can become particularly important if a dispute later arises about whether valid notice was given.
What Happens After a Party Wall Notice Is Served?
Receiving a Party Wall Notice does not automatically mean that your neighbour has to agree to the proposed works.
The adjoining owner may:
- Consent to the works.
- Dissent and appoint a Party Wall Surveyor.
- Dissent and agree to use an agreed surveyor where appropriate.
- Take other steps available under the Party Wall Act.
The next stage will depend on the response from the adjoining owner.
What If My Neighbour Consents?
If the adjoining owner provides the appropriate consent, the works may be able to proceed without the need for a Party Wall Award, subject to the particular circumstances and the terms of the consent.
However, it is important to distinguish between consent to the works and broader issues concerning damage or access.
You should keep a proper record of the notice and the adjoining owner’s response.
What If My Neighbour Does Not Consent?
A neighbour does not necessarily have to consent to your proposed works.
If they dissent, the Party Wall Act provides a procedure for dealing with the disagreement.
This can involve the appointment of:
- An agreed Party Wall Surveyor; or
- Separate surveyors representing each owner.
The surveyor or surveyors can then deal with the matter in accordance with the statutory procedure and, where necessary, prepare a Party Wall Award.
What Is a Party Wall Award?
A Party Wall Award is a legally binding document prepared under the Party Wall Act to regulate certain works and protect the interests of the affected owners.
It may set out:
- The works permitted
- How and when the work can be carried out
- Access arrangements
- Protective measures
- Conditions relating to damage
- Surveyor’s fees
- Other matters relevant to the works
A Party Wall Award should not be confused with a Party Wall Notice.
The notice informs the adjoining owner about the proposed works, while an award determines the rights and obligations arising where the statutory procedure requires one.
Do I Need a Party Wall Surveyor?
You may not need a surveyor if the adjoining owner consents to the works and the circumstances do not require further action under the Act.
However, if the adjoining owner dissents, a Party Wall Surveyor will generally become involved.
A surveyor can help:
- Assess the proposed works
- Protect the adjoining owner’s interests
- Prepare a schedule of conditions
- Agree the terms of a Party Wall Award
- Deal with disputes
- Monitor compliance with the award
A building owner may also appoint a surveyor at an early stage to help manage the party wall process.
Can I Start Work Without Serving a Party Wall Notice?
You should not assume that you can begin work simply because you have planning permission or building regulations approval.
Planning permission and the Party Wall Act are separate legal matters.
You may have obtained planning permission and still have a legal obligation to serve a Party Wall Notice.
Starting work without complying with the Party Wall Act can expose you to potential disputes and legal action.
Your neighbour may be able to seek an injunction or other remedies depending on the circumstances.
Getting the party wall process right before work starts is therefore extremely important.
What Happens If You Fail to Serve a Party Wall Notice?
Failing to serve a required notice can create significant complications.
For example, your neighbour may:
- Object to the works
- Seek legal advice
- Apply for an injunction
- Claim that the statutory procedure has not been followed
- Raise concerns about damage
- Seek compensation where legally appropriate
A failure to comply with the Party Wall Act can also cause practical delays to your construction project.
It is generally much easier to deal with party wall requirements before work starts than after a dispute has developed.
Party Wall Notice and Planning Permission: What’s the Difference?
This is one of the most common questions from property owners.
A planning application concerns whether a proposed development is acceptable under planning law.
A Party Wall Notice concerns your legal obligations towards neighbouring owners under the Party Wall etc. Act 1996.
They are separate processes.
For example, you could have:
- Planning permission
- Building regulations approval
- Architectural drawings
- Structural calculations
And still need to serve a Party Wall Notice.
Obtaining one approval does not automatically satisfy the other legal requirements.
How Much Does a Party Wall Notice Cost?
The cost of dealing with a Party Wall Notice varies depending on the circumstances.
Factors can include:
- The complexity of the proposed works
- The number of adjoining owners
- Whether a surveyor is required
- Whether a Party Wall Award is necessary
- Whether the matter becomes disputed
- The complexity of the documentation
If you are planning work that may fall within the Party Wall Act, obtaining professional advice at an early stage can help you understand the likely costs and avoid unnecessary expenses later.
Can a Party Wall Notice Be Withdrawn?
In some circumstances, a notice may be withdrawn, or the proposed works may change before construction begins.
However, the appropriate legal approach will depend on the circumstances and the stage reached in the statutory process.
If your plans have changed after serving a notice, it is advisable to obtain advice before simply assuming that the original notice covers the revised works.
How Long Does a Party Wall Notice Last?
The Party Wall Act does not simply operate on the basis of a notice remaining valid indefinitely.
The effect of a notice depends on the type of notice, the proposed works,s and the statutory procedure that follows.
If significant time has passed or the proposed works have materially changed, it is sensible to obtain professional advice before commencing construction.
Do You Need Legal Advice Before Serving a Party Wall Notice?
Although it is possible for a building owner to deal with certain aspects of the Party Wall process without a solicitor, professional advice can be valuable where:
- The works are complex.
- The boundary is disputed.
- There are multiple adjoining owners.
- Your neighbour has already objected.
- The works involve significant excavation.
- The project involves a shared structure.
- You are concerned about potential damage.
- A previous Party Wall Award exists.
- You are unsure which notice needs to be served.
Early advice can help identify problems before they result in delays or expensive disputes.

Frequently Asked Questions About Party Wall Notices
What is a Party Wall Notice?
A Party Wall Notice is a formal notice informing an adjoining owner about proposed works that fall within the scope of the Party Wall etc. Act 1996.
How long before building work should a Party Wall Notice be served?
The statutory notice period depends on the type of work. Certain notices require at least one month’s notice, while certain works to an existing party structure require at least two months’ notice.
Can I serve a Party Wall Notice myself?
In some cases, yes. However, you should ensure that the correct notice is being used, the correct owners are identified, and the statutory requirements for service are followed.
Does planning permission mean I don’t need a Party Wall Notice?
No. Planning permission and the Party Wall Act are separate legal requirements. You may need to comply with both.
What happens if my neighbour ignores a Party Wall Notice?
The appropriate response depends on the circumstances. If the adjoining owner does not respond within the relevant statutory period, the Party Wall Act may provide mechanisms for proceeding, including the appointment of a surveyor.
Can my neighbour stop my building work?
A neighbour’s rights depend on the nature of your proposed works and whether the Party Wall Act applies. They may be able to take legal action if statutory requirements have not been followed.
Do I need a Party Wall Agreement?
Not necessarily. The appropriate document or procedure depends on the type of work and the response of the adjoining owner. In some circumstances, a Party Wall Award may be required rather than a simple agreement.
What is the difference between a Party Wall Notice and a Party Wall Agreement?
A Party Wall Notice informs the adjoining owner about proposed works. A Party Wall Agreement is generally used to record an agreed position between the parties, although the precise legal document required will depend on the circumstances.
What should I do if I receive a Party Wall Notice?
Read the notice carefully and consider whether you consent or dissent. If you have concerns about the proposed works, particularly excavation, structural alterations, or potential damage, consider obtaining independent professional advice before responding.
