If you are planning building works in England and Wales, understanding the role of party wall surveyors is essential. Whether you are a building owner carrying out works or an adjoining owner responding to a notice, the Party Wall etc. Act 1996 creates a specialist legal process designed to protect both parties and help works proceed properly.
Many people assume that a party wall surveyor simply acts for the person who appoints them. In reality, once formally appointed under the Act, a party wall surveyor takes on a statutory role and must act impartially when dealing with matters in dispute.
In this article, we explain what a party wall surveyor does, the different types of party wall surveyor, and how the party wall process works under the Act.
What Does a Party Wall Surveyor Do?
A party wall surveyor is responsible for dealing with disputes and procedural matters that arise under the Party Wall etc. Act 1996.
Their role may include:
- reviewing whether proposed works fall within the Act
- preparing and serving party wall notices
- advising on adjoining owners and statutory procedure
- inspecting affected property
- recording condition before works begin
- negotiating and agreeing a party wall award
- dealing with access arrangements
- resolving disputes about damage or compensation
- allocating party wall surveyor fees and costs
A party wall surveyor’s role is not simply administrative. They help create the legal framework within which the works can proceed.
When Are Party Wall Surveyors Needed?
Party wall surveyors are generally needed when a dispute arises under the Act. This commonly happens where an adjoining owner:
- dissents to a party wall notice
- does not respond to a notice within the statutory timeframe
- raises concerns that require formal determination under the Act
This can apply to a wide range of projects, including:
- loft conversions
- rear extensions
- side extensions
- wraparound extensions
- basement works
- chimney breast removals
- structural alterations
- excavation near neighbouring property
- building on the boundary line
Where the Act applies and a dispute arises, the surveyor process under section 10 of the Party Wall etc. Act 1996 comes into play.
Types of Party Wall Surveyor
There are four main types of party wall surveyor commonly referred to in practice.
Building Owner’s Surveyor
The building owner’s surveyor is the surveyor appointed by the owner carrying out the works.
Despite the label, this surveyor is not there simply to push the project through regardless of consequence. Their role is to participate in the statutory process, review the works, and help ensure that the building owner can proceed lawfully while the adjoining owner is properly protected.
Adjoining Owner’s Surveyor
The adjoining owner’s surveyor is the surveyor appointed by the neighbouring owner affected by the proposed works.
This surveyor’s role is to examine the proposals, review the likely impact on the adjoining property, and work with the other surveyor to agree a fair and legally compliant party wall award.
Agreed Surveyor
An agreed surveyor is a single surveyor appointed by both the building owner and the adjoining owner.
This can be a quicker and more cost-effective route, particularly where the works are relatively straightforward and both parties are comfortable using one surveyor. Even though only one surveyor is involved, they must still act impartially for both owners.
Third Surveyor
The third surveyor is selected by the two appointed surveyors in the two-surveyor route.
They are not normally involved in the day-to-day running of the matter. Their purpose is to act as a statutory safeguard if the two appointed surveyors cannot agree on a particular issue. If that happens, the matter can be referred to the third surveyor for determination.
Are Party Wall Surveyors Impartial?
Yes. This is one of the most important points to understand.
Although owners often refer to “their” surveyor, a party wall surveyor appointed under the Act must act impartially. They are not an ordinary agent or advocate in the usual sense. Their role is to deal with the matter under the statutory framework of the Party Wall etc. Act 1996, not simply to carry out instructions from the person who appointed them.
This applies whether the surveyor is acting as:
- the building owner’s surveyor
- the adjoining owner’s surveyor
- the agreed surveyor
- the third surveyor
Impartiality is at the heart of the party wall process and is one of the key reasons the system works.
Building Owner’s Surveyor vs Adjoining Owner’s Surveyor
A common question is whether the building owner’s surveyor and adjoining owner’s surveyor are effectively acting against one another.
In practice, they should not be.
Both surveyors are part of a statutory tribunal process. Their role is to work together to agree the terms of the party wall award. That means they must consider the facts, the proposed works, the likely impact, and the protections required under the Act.
Good party wall surveyors do not treat the process as a battle. They work constructively to get the matter resolved fairly and efficiently.
Agreed Surveyor vs Two Surveyors
Another common question is whether it is better to appoint an agreed surveyor or have two party wall surveyors.
Agreed Surveyor
The agreed surveyor route can be beneficial because it is often:
- quicker
- more cost-effective
- simpler to administer
It is commonly used for straightforward residential projects where both owners are comfortable with one surveyor acting under the Act.
Two Surveyors
The two-surveyor route may be more suitable where:
- the works are more complex
- neighbour relations are strained
- the adjoining owner wants separate professional involvement
- there is greater structural or access risk
This route also includes the additional safeguard of the third surveyor if the two appointed surveyors cannot agree.
What Is a Party Wall Award?
A party wall award is the formal legal document prepared by the surveyor or surveyors once a dispute has arisen.
The award typically sets out:
- the works that are authorised
- how those works are to be carried out
- protective measures for the adjoining owner’s property
- access arrangements
- working hours and site conduct
- how damage is to be dealt with
- who is responsible for costs and fees
The party wall award is one of the most important outputs of the surveyor process. It gives structure and legal clarity to the project.
What Powers Do Party Wall Surveyors Have?
Party wall surveyors have significant powers under the Act, but those powers are limited to matters within the scope of the legislation.
Their powers generally include:
- determining disputes under the Act
- making and serving awards
- regulating the manner and timing of works
- determining compensation issues connected with the notifiable works
- allocating costs between the parties
They must, however, stay within the limits of the Act. A surveyor cannot simply decide whatever they like, nor can they use the award to authorise matters that fall outside the legislation.
Who Pays Party Wall Surveyor Fees?
In most cases, the building owner will be responsible for the reasonable party wall surveyor fees, particularly where the surveyor involvement arises because of the building owner’s proposed works.
This can include:
- the building owner’s surveyor’s fees
- the adjoining owner’s surveyor’s fees
- third surveyor fees, where applicable
The issue of costs is usually dealt with in the party wall award. Fees should be reasonable and proportionate to the work undertaken.
Why Good Party Wall Surveyors Matter
The quality of the party wall surveyor involved can make a major difference to the outcome.
A good surveyor will:
- understand the Party Wall etc. Act 1996 properly
- communicate clearly with both owners
- identify the real issues quickly
- avoid unnecessary escalation
- keep the process moving
- draft practical and enforceable awards
- ensure costs remain proportionate
Poor surveyor conduct, by contrast, can increase delay, cost and neighbour tension.
Why the Party Wall Process Is Separate from Planning Permission
One of the most common misunderstandings is that planning permission overrides party wall matters.
It does not.
The Party Wall etc. Act 1996 is entirely separate from:
- planning permission
- permitted development rights
- building regulations approval
A building owner may have full planning consent for the works and still need to serve party wall notices and go through the surveyor process before the works can lawfully proceed under the Act.
Final Thoughts on Party Wall Surveyors
Party wall surveyors play a central role in the statutory framework created by the Party Wall etc. Act 1996 in England and Wales. Whether acting as the building owner’s surveyor, adjoining owner’s surveyor, agreed surveyor or third surveyor, their role is to administer the Act fairly and help resolve disputes connected with notifiable works.
The most important point for owners to understand is that party wall surveyors are not ordinary agents. They are statutory decision-makers who must act impartially and within the powers given by the Act.
When properly managed, the party wall process allows works to proceed while protecting both sides and reducing the risk of more serious disputes later.
