What Does a Party Wall Surveyor Do? Understanding the Role of the Party Wall Surveyor

The role of a Party Wall Surveyor is a vital aspect of construction and property management in the United Kingdom. This professional is crucial in situations where a property owner is planning to undertake any work that is covered under the Party Wall etc. Act 1996. But what exactly does a Party Wall Surveyor do, and why are their services so important?

The Basics of Party Wall Surveying

A Party Wall Surveyor is a specialist who ensures that all construction work involving party walls, boundary walls, and excavations near neighbouring buildings is carried out legally and fairly. Their primary role is to mitigate the risks associated with construction work that affects adjoining properties.

Understanding the Party Wall etc. Act 1996

To appreciate the role of a Party Wall Surveyor fully, one must first understand the Party Wall etc. Act 1996. This legislation provides a framework for preventing and resolving disputes related to party walls, boundary walls, and excavations near neighbouring buildings. The Act applies throughout England and Wales, including major areas like London, where property proximity can often lead to disputes.

Key Responsibilities of a Party Wall Surveyor

1. Serving Party Wall Notices: One of the primary responsibilities of a Party Wall Surveyor is to serve notices to adjoining property owners (known as Adjoining Owners). These notices are required when a property owner (known as the Building Owner) intends to carry out work covered by the Act.

2. Preparing a Schedule of Condition: Before any work commences, a Party Wall Surveyor often prepares a Schedule of Condition of the adjoining property. This document records the existing condition of the property to address any potential damage claims that might arise due to construction work.

3. Drafting Party Wall Awards: A critical duty is drafting the Party Wall Award or Agreement. This legal document sets out the rights and responsibilities of both the Building Owner and the Adjoining Owner, detailing how the proposed works should progress.

4. Resolving Disputes: If a dispute arises, Party Wall Surveyors from both sides (or a single agreed-upon Surveyor) work to resolve the issues, ensuring that the work complies with the Act and that the interests of both parties are protected.

5. Ensuring Compliance and Safety: Surveyors ensure that all construction work adheres to the detailed terms in the Party Wall Award, focusing on safety and minimizing inconvenience to adjoining property owners.

The Importance of a Party Wall Surveyor

The importance of a Party Wall Surveyor cannot be overstated. Their involvement ensures that:

  • Construction work is legally compliant.
  • Potential disputes are resolved amicably and fairly.
  • Adjoining properties are protected from damage.
  • The rights of all parties are upheld.

  • Excavating within 3 or 6 meters of a neighbouring property** (depending on the depth of the foundations).

Choosing the Right Party Wall Surveyor

Selecting the right Party Wall Surveyor is crucial. You should look for professionals who are knowledgeable, experienced, and preferably members of recognized industry bodies like the Faculty of Party Wall Surveyors or the Royal Institution of Chartered Surveyors (RICS). They should have a solid understanding of the law and possess good negotiation skills to resolve any disputes amicably.

The Role in Loft Conversions, Extensions, and Basement Works

In projects like loft conversions, rear extensions, and basement works, the role of a Party Wall Surveyor becomes even more significant. These types of projects often have a direct impact on the party wall, requiring detailed agreements and careful monitoring to ensure compliance with the Act.
