Party Wall Agreements Explained

In this guide, we’re going to explain exactly what a party wall agreement is, when you need one, and what it actually involves.

If you are planning works or have received a notice from your neighbour, this will help you understand what is required and what happens next.

What Is a Party Wall Agreement?

A party wall agreement is a written agreement between neighbours that allows certain works to proceed under the Party Wall etc. Act 1996.

In practice, the term is often used to describe one of two things:

• A written consent from your neighbour after you serve notice
• A formal party wall award prepared by surveyors if there is a dispute

Strictly speaking, the Act refers to notices and awards. The word “agreement” is commonly used to describe the overall outcome.

Is a Party Wall Agreement a Legal Requirement?

If your proposed works fall within the scope of the Party Wall Act, serving notice is a legal requirement.

Whether you need a formal award depends on your neighbour’s response.

If they consent in writing within 14 days of receiving the notice, you may proceed without appointing surveyors. You must still wait for the statutory notice period to run, unless your neighbour has agreed to waive it (they should be encouraged to do this on the notice acknowledgement if consenting).

If they dissent or don’t respond in that timeframe, a dispute is deemed to have arisen and surveyors must be appointed. At that point, a party wall award becomes compulsory.

So while an “agreement” in informal terms may not always be required, compliance with the Act is.

When Do You Need a Party Wall Agreement?

You will need to follow the party wall procedure if you plan to:

• Cut into a shared wall
• Insert steel beams
• Remove a chimney breast attached to the wall
• Raise or underpin a party wall
• Excavate within 3 metres of a neighbouring or shared structure and deeper than its foundations
• Build on the line of junction

Loft conversions, rear extensions and basement works are common triggers.

If your works fall into one of these categories, you must serve the necessary notices before starting.

When Do You Not Need a Party Wall Agreement?

You don’t normally need to serve notice for minor works such as:

• Replastering
• Fitting kitchen units
• Installing shelves
• Electrical rewiring that does not cut into the wall

The key test is whether the work affects the structure or involves excavation near foundations.

If you’re unsure, it’s safer to check early rather than assume the Act does not apply.

What Does a Party Wall Agreement Look Like and What Does It Cover?

If your neighbour consents to the notice(s), the ‘agreement’ may simply be a signed written confirmation.

If surveyors are appointed, they will produce a party wall award. That’s a formal document that includes:

• Details of the proposed works
• Protective measures
• Access rights (if applicable)
• Procedures for dealing with damage
• Allocation of surveyor fees
• Drawings and structural information
• A schedule of condition of the adjoining property

The award is legally binding once served, unless successfully appealed within 14 days.

How Long Does a Party Wall Agreement Last?

A party wall award typically remains valid for 12 months from the date it’s served although the precise time period is for the surveyors to agree.

If works don’t commence within that period, the process will need to be restarted.

Consent agreements relate specifically to the works described in the notice and are valid for 12 months. If the scope changes significantly, a new notice may be required.

Is a Party Wall Agreement Legally Binding?

A party wall award is legally binding under the Act.

A simple written consent is also binding in relation to the works described, although it doesn’t provide the sort of specific protection that would be included in a formal award.

Once an award is served, it can only be challenged by appealing to the County Court within 14 days.

Do You Need a Party Wall Surveyor?

You need a party wall surveyor in the event that your neighbour dissents to the notice(s)s.

The surveyor’s role is to act impartially and apply the Act, not to favour one side.

If your neighbour consents in writing after receiving notice, surveyors will not be required.

We explain the role of a party wall surveyor in more detail in our separate guide.

What Is the Process to Follow for a Party Wall Agreement?

The typical process is:

• Confirm whether your works fall within the Act
• Serve the correct written notice
• Wait 14 days for a response
• If consent is given, proceed with work once the statutory notice period has run (or been waived)
• If there is a dissent, appoint surveyor or surveyors
• Wait for the party wall award to be agreed and served
• Commence works in accordance with the award

Timing matters. Notice periods apply, and you cannot lawfully begin notifiable works until the process is complete.

What Are Party Wall Rights?

Under the Act, building owners have the right to carry out certain works provided they follow the procedure.

Adjoining owners have the right to:

• Receive proper notice
• Dissent and appoint a surveyor
• Have their property protected from damage (which typically includes a schedule of condition being recorded)
• Appeal an award within 14 days

The Act balances these rights so that development can proceed without unnecessary inconvenience to the adjoining owner.

Are Party Wall Agreements Registered?

Party wall awards aren’t automatically registered with the Land Registry.

They remain legally binding between the parties involved but are not recorded as a public title restriction.

Am I Entitled to a Copy of the Party Wall Agreement?

Yes, both the building owner and adjoining owner are entitled to copies of notices and any award made under the Act.

You should keep these documents safe, as they may be relevant if questions arise later.

Can Tenants Request a Party Wall Agreement?

Tenants are entitled to be formally notified under the Act if they have an interest of greater than 12 months. In practical terms, this means their tenancy agreement must have an unexpired term of 12 months or more (factoring in any break clauses).

If entitled to a notice, tenants have all the same rights as freehold and leasehold owners including the right to dissent to a notice and appoint a surveyor.

What Is a Third-Party Wall Agreement?

The Act doesn’t use the term “third-party wall agreement” in a formal sense.

In practice, people sometimes use this phrase when multiple adjoining owners are involved in the same project. Each adjoining owner may require a separate notice and potentially a separate award.
