Role of Party Wall Surveyor

The role of a party wall surveyor is set out within the Party Wall etc. Act 1996. A party wall surveyor is appointed to deal with matters arising from building works that affect shared walls, boundary structures or neighbouring property. Their role is professional, statutory and impartial.

This guide explains what a party wall surveyor does, when they are appointed and how they help protect both building owners and adjoining owners. At Bloomsbury Surveyors, we provide professional party wall advice across Brighton, Hove and Sussex for both domestic and commercial projects.

What Is a Party Wall Surveyor?

A party wall surveyor is a professional appointed under the Party Wall etc. Act 1996 once the statutory process requires surveyor involvement. Although the term includes the word surveyor, the role is not limited to inspection alone. A party wall surveyor is responsible for resolving matters arising under the Act and preparing the documentation needed to regulate the works properly.

The surveyor’s duty is to the Act itself rather than simply to the person who appointed them. That is one of the most important features of the role.

When Is a Party Wall Surveyor Appointed?

A party wall surveyor is usually appointed when a party wall notice has been served and the adjoining owner dissents or does not respond within the statutory period. At that point, a dispute is deemed to have arisen under the Act and surveyors can be appointed to resolve the matter.

Surveyor appointments often arise on projects such as:

Loft conversions involving steel beams in a party wall
Extensions involving excavation near neighbouring structures
Basement excavations and underpinning
Commercial refurbishment projects affecting shared walls
Structural alterations to party walls

Who Can a Party Wall Surveyor Act For?

A party wall surveyor may be appointed by the building owner, by the adjoining owner or jointly by both owners as the agreed surveyor. In each case, the surveyor must act impartially in accordance with the Act.

There are usually three main appointment routes:

One surveyor appointed by the building owner
One surveyor appointed by the adjoining owner
One agreed surveyor appointed by both parties

Where separate surveyors are appointed, they work together to agree the terms of the Party Wall Award.

The Surveyor’s Main Duties

A party wall surveyor has a number of core duties under the Act. These duties vary depending on the project, but commonly include the following:

Reviewing the proposed works
Assessing whether the works fall within the Act
Considering technical risk to adjoining property
Inspecting the adjoining owner’s property where necessary
Preparing a schedule of condition
Drafting and serving the Party Wall Award
Resolving disputes between owners
Assessing issues arising during or after the works

This makes the role part legal process, part technical assessment and part dispute resolution.

Preparing the Party Wall Award

One of the most important duties of a party wall surveyor is preparing the Party Wall Award. This is the legally binding document that sets out how the works may proceed and what protections must be in place.

Award documents often include:

A description of the works
Supporting drawings
Access arrangements
Protective measures
Working conditions
A schedule of condition
Fee provisions

You can read more on our Party Wall Award Explained page and our Party Wall Awards Brighton page.

Preparing the Schedule of Condition

A schedule of condition is a written and photographic record of the visible condition of the adjoining property before works begin. Party wall surveyors often prepare this document so there is a clear record if damage is later alleged.

This is especially important in Brighton and Hove where many properties are older and may already contain historic cracking or signs of movement.

Acting Impartially

One of the most misunderstood aspects of the role is impartiality. Even where a surveyor is appointed by one owner, the surveyor must not simply act as that person’s advocate. Their duty is to administer the Act properly and fairly.

This impartial role is essential to the integrity of the party wall process. It helps ensure that both parties are treated fairly and that decisions are based on professional judgement rather than personal preference.

Resolving Disputes

Party wall surveyors are responsible for resolving disputes that arise under the Act. This may include disputes about the proposed works, concerns about structural risk, access arrangements, protective measures or alleged damage.

Where two surveyors are appointed and they cannot agree, the third surveyor may be asked to determine the point in dispute.

What a Party Wall Surveyor Does Not Do

It is also useful to understand what a party wall surveyor is not there to do. A party wall surveyor is not a contractor, not a structural engineer and not a general project manager. They are also not there simply to fight one owner’s corner.

The role is specific to the legal and procedural framework of the Party Wall Act. Good surveyors understand both the technical and statutory sides of the process and apply that knowledge carefully.

Why Professional Surveyor Advice Matters

Professional party wall advice helps ensure the process is handled correctly from the start. This reduces errors, protects neighbouring property and supports smoother project delivery.

Using an experienced party wall surveyor can help:

Identify whether the Act applies
Reduce the risk of procedural mistakes
Provide clear technical documentation
Protect both owners fairly
Reduce unnecessary disputes
