If you are planning building work that affects a shared wall, boundary or neighbouring property, appointing a party wall surveyor in London can help you understand your legal obligations and reduce the risk of disputes.
The Party Wall etc. Act 1996 provides a legal framework for certain types of building work affecting adjoining properties. Depending on the proposed works, a building owner may need to serve a formal party wall notice and follow the appropriate procedure before construction begins.
At Charrette Law, we advise property owners, developers and adjoining owners on party wall matters, helping them understand the requirements of the Act and take the appropriate steps before works commence.
When Do You Need a Party Wall Surveyor in London?
A party wall surveyor may be required where proposed building works fall within the scope of the Party Wall etc. Act 1996.
This can include works such as:
- Building on or near a boundary
- Cutting into or altering a party wall
- Removing a chimney breast from a party wall
- Carrying out structural work affecting a party wall
- Excavating near a neighbouring building
- Constructing a new wall on or close to the boundary
- Basement extensions and similar excavation works
The need for a party wall agreement depends on the nature and location of the proposed works, rather than simply whether planning permission has been granted.
What Does a Party Wall Surveyor Do?
A party wall surveyor provides professional advice and manages the relevant procedures under the Party Wall etc. Act 1996.
Their role may include:
Reviewing the Proposed Works
The surveyor considers the proposed construction works and determines whether they are likely to fall within the scope of the Party Wall Act.
Advising on Notices
Where the Act applies, the appropriate party wall notice must be served on affected adjoining owners. A surveyor can help ensure the correct procedure is followed.
Preparing a Schedule of Condition
A schedule of condition can document the condition of an adjoining property before works begin. This may provide useful evidence if damage is alleged during or after construction.
Preparing a Party Wall Award
Where an agreement cannot be reached directly, surveyors may prepare a party wall award setting out the rights and responsibilities of the relevant owners and the conditions under which the works can proceed.
Dealing With Disputes
Party wall matters can become contentious where neighbours disagree about proposed works, access, damage or responsibility for costs. A surveyor can help manage the formal dispute-resolution process.
Party Wall Surveyor vs Planning Permission
Party wall procedures and planning permission are separate legal requirements.
Obtaining planning permission does not automatically give a building owner the right to carry out works affecting a party wall or neighbouring property.
Similarly, complying with the Party Wall Act does not replace the need for planning permission, building regulations approval or other permissions that may apply.
Property owners should therefore consider planning, building regulations and party wall requirements together when preparing for construction work.
Why Use a Party Wall Surveyor in London?
London properties often involve close boundaries, terraced houses, flats, extensions, basement works and other developments where construction can directly affect neighbouring properties.
Professional party wall advice can help to:
- Identify whether the Party Wall Act applies
- Ensure notices are served correctly
- Reduce the risk of procedural errors
- Establish the condition of neighbouring property before works
- Clarify rights and responsibilities
- Manage disagreements with adjoining owners
- Provide documentation before construction begins
Early advice can be particularly valuable where construction works are scheduled to start soon.
Party Wall Disputes in London
Disputes can arise for several reasons, including disagreement over proposed works, concerns about structural damage, access requirements or the cost of the party wall process.
Where adjoining owners do not consent to the proposed works, the statutory procedure may require the appointment of surveyors and the preparation of a party wall award.
A properly prepared award can establish the conditions under which the works may proceed and help protect the interests of both the building owner and adjoining owner.
How Much Does a Party Wall Surveyor Cost in London?
The cost of a party wall surveyor in London can vary depending on the complexity of the proposed works, the number of adjoining owners involved, whether a dispute has arisen and the amount of work required.
Simple matters may involve relatively limited professional work, while complex developments involving multiple adjoining properties, structural alterations or disputes can result in higher fees.
The person responsible for the surveyor’s costs can also depend on the circumstances and the nature of the works.
Obtaining advice at an early stage can help property owners understand the likely process and costs before construction begins.

Frequently Asked Questions
What is a party wall?
A party wall is generally a wall that is shared by two adjoining properties, such as the dividing wall between two terraced or semi-detached houses. The Party Wall etc. Act 1996 also covers certain other types of party structures and boundary-related works.
Do I need a party wall surveyor for an extension?
You may need to follow the Party Wall Act procedure if your extension involves work covered by the Act, such as building on the boundary, cutting into a party wall or excavating close to a neighbouring building.
Does planning permission cover party wall matters?
No. Planning permission and the Party Wall Act are separate matters. A property owner may need to comply with both requirements before carrying out certain building works.
Can my neighbour stop my building work?
An adjoining owner may have rights under the Party Wall Act depending on the proposed works and circumstances. Following the correct statutory procedure is important where the Act applies.
When should I appoint a party wall surveyor?
Party wall matters should ideally be addressed before construction begins. Early advice can help establish whether notices are required and prevent avoidable delays or disputes.
