But what is party wall surveying, and why is it essential for property owners to be well-versed in their rights and responsibilities under the Party Wall Act 1996? In this blog post, we will delve into the intricacies of party wall surveying, highlighting the purpose of the legislation and situations where the Party Wall Act applies. Subsequently, we will outline a property owner's responsibilities when undertaking work on shared walls and explain the role of party wall surveyors in the process. By gaining a thorough understanding of this subject matter, property owners can ensure their developments progress smoothly and avoid potential disputes with their neighbours.

The Purpose of the Party Wall Act 1996

The Party Wall Act 1996 serves to protect the rights and interests of property owners when undertaking work that may impact shared boundaries or walls. The primary objectives of this legislation are to:

1. Provide a legal framework and guidelines for property owners initiating construction or renovation projects that could affect party walls or structures.

2. Ensure neighbours affected by such works are consulted and informed about the proposed developments.

3. Offer a dispute resolution mechanism through party wall surveying, should disagreements about proposed works arise.

When Does the Party Wall Act Apply?

Understanding when the Party Wall Act comes into play is crucial for property owners. The Act becomes relevant when a property owner intends to carry out works that fall under one of the following categories:

a) Construction of a new wall on the boundary line between two properties.

b) Renovation, alteration, or repair of a shared wall or structure (party wall).

c) Excavation works in close proximity to the neighbour's building, which could potentially undermine its structural integrity.

If your planned construction or renovation project falls under any of these categories, you are legally obligated to comply with the provisions stated in the Party Wall Act.

Property Owner's Responsibilities Under the Party Wall Act

When undertaking works subject to the Party Wall Act, property owners are required to fulfil certain obligations:

1. Serve Notice: The Act mandates that the property owner, or their representative, must provide written notice to affected neighbours, outlining the planned works and their commencement date. Different types of works require specific notices with varying notice periods:

- For a new wall on the boundary line: "Line of Junction" notice, served one month before the planned work.

- For alterations or repairs on an existing shared structure: "Party Structure" notice, served two months before the planned work.

- For excavation works near a neighbour's property: "Notice of Adjacent Excavation", served one month before the planned work.

2. Obtain Consent: Once a neighbour receives the notice, they have 14 days to respond. If they agree to the proposed works, the property owner may proceed as planned. If no response is received or a counter-notice is issued, a dispute arises, and the party wall surveying process must be initiated.

3. Arrange for a Party Wall Survey: In the event of a dispute, both parties need to appoint a professional party wall surveyor to resolve the disagreement. This surveyor will prepare a "Party Wall Award", outlining the agreed works and dispute resolution conditions.

The Role of Party Wall Surveyors

Party wall surveyors play a pivotal role in managing disputes under the Party Wall Act. Their primary responsibilities include:

1. Advice and Guidance: Party wall surveyors can assist property owners in understanding their rights and obligations under the Party Wall Act and provide guidelines on serving notices to neighbours.

2. Drafting and Serving Notices: Surveyors can also draft and serve compliant party wall notices on behalf of property owners, ensuring legal requirements are met.

3. Assessing Damage Risks: Prior to the commencement of works, a party wall surveyor can conduct a pre-work condition survey, documenting the existing condition of the neighbouring property, and highlight potential damage risks associated with the proposed works.

4. Dispute Resolution and Party Wall Award: When disputes arise, party wall surveyors act as impartial arbiters and draft the Party Wall Award, outlining the conditions and terms for executing the works as per the Act’s guidelines.


Understanding the Party Wall Act and party wall surveying is essential for property owners undertaking construction or renovation projects that may impact shared walls or structures. By adhering to the provisions of the Act and engaging a professional party wall surveyor, property owners can avoid disputes, maintain neighbourly relations, and ensure the smooth execution of their projects.
