When planning construction work on your property, understanding the role of party wall surveyors is essential. Whether you’re building an extension, converting a loft, excavating a basement, or carrying out structural alterations near a shared boundary, complying with party wall legislation can help you avoid disputes and costly delays.
This guide explains what professional party wall surveyors do, when you need them, and how they can protect both property owners and neighbouring properties throughout a building project.
What Are Party Wall Surveyors?
Party wall surveyors are qualified professionals who specialize in resolving matters related to shared walls, boundaries, and structures between neighboring properties. Their primary role is to ensure that construction work complies with the Party Wall etc. Act 1996 and that the rights of all parties involved are protected.
A surveyor acts impartially, even when appointed by one property owner, to ensure that construction activities do not cause unnecessary damage or disputes.
Companies such as Set Square Surveyor provide expert guidance throughout the party wall process, helping homeowners, developers, and commercial property owners navigate legal requirements efficiently.

When Do You Need Party Wall Surveyors?

- Rear or side extensions
- Basement excavations

- Constructing new walls at the property boundary
If your project falls under the Party Wall etc. Act 1996, you must serve the appropriate notices to adjoining property owners before work begins.
Key Responsibilities of Party Wall Surveyors
1. Serving and Reviewing Party Wall Notices

Surveyors ensure that notices contain all required information and are issued within the correct timeframe.
2. Preparing Party Wall Awards
If adjoining owners disagree with the proposed works, surveyors prepare a legally binding document known as a Party Wall Award.
The award outlines:
- The scope of construction work
- Working hours
- Protective measures
- Access arrangements

This document protects both parties throughout the project.
3. Conducting Schedule of Condition Reports
Before work starts, professional party wall surveyors conduct detailed inspections of neighboring properties.
The resulting Schedule of Condition report documents:
