A Party Wall Agreement is a commonly used term for the legal process that allows certain building works to proceed under the Party Wall etc. Act 1996. In many cases, the process starts with a Party Wall Notice being served on the adjoining owner.
If your neighbour consents to the notice, the matter may be straightforward. If they dissent or do not respond, a formal Party Wall Award may be needed before work can begin.
Many homeowners use the phrase “Party Wall Agreement” to describe the full process, but the exact document required depends on the neighbour’s response and the type of work being carried out.

You may need a Party Wall Agreement if your work affects a shared wall, boundary line, or excavation close to a neighbouring property.
Common examples include inserting steel beams into a party wall for a loft conversion, building a rear extension with foundations near a neighbour’s property, removing a chimney breast from a shared wall, building on or close to a boundary line, or excavating for a basement or deeper foundations.
In London, Party Wall matters are especially common because many homes are terraced, semi-detached, converted into flats, or built close to neighbouring buildings.
If your neighbour dissents or does not reply, you may need a Party Wall Award in London before work begins.
Loft conversions are one of the most common reasons homeowners need Party Wall advice. If your loft conversion involves steel beams being inserted into a shared wall, raising a party wall, or cutting into a party structure, a Party Wall Notice may be required.
This is common in terraced and semi-detached homes across London. Even if your loft conversion does not need planning permission, it may still fall under the Party Wall etc. Act 1996.
Starting the process early helps avoid delays once your builder is ready to begin.
Rear extensions, side return extensions and wraparound extensions often require Party Wall Notices because they may involve excavation close to neighbouring foundations or work near the boundary line.
If the proposed foundations are within the relevant distance of a neighbouring property, notice may be required before the work starts. Boundary wall works may also require a separate notice depending on the design.
A clear Party Wall process helps reduce neighbour concerns and keeps the project properly documented.

A Party Wall Agreement does not have to be difficult or confrontational. In many cases, the process simply gives your neighbour clear information about the proposed works and gives both sides a formal record before construction begins.
If your neighbour consents to the notice, the project can usually move forward without a Party Wall Award. If they dissent, surveyors become involved and an Award may be prepared.
Good communication, correct notices and clear project information can help avoid unnecessary disputes.
If your neighbour consents in writing after receiving the correct Party Wall Notice, a formal Party Wall Award is usually not required.
However, you may still want a Schedule of Condition before work starts. This records the condition of the adjoining property and can help avoid disagreement if damage is alleged later.
Consent does not remove the need to take care during the works. It simply means the neighbour is not requiring a formal surveyor-led Award at that stage.
If your neighbour dissents, it does not usually mean they are trying to stop your building work. It means they want the work handled formally under the Party Wall process.
When dissent occurs, either one Agreed Surveyor can act for both owners, or each owner can appoint their own surveyor. The surveyor or surveyors then prepare a Party Wall Award.
The Award sets out how the work should be carried out, access arrangements, protective measures, working hours and what happens if damage occurs.
A Party Wall Notice is the document served at the start of the process. It informs the adjoining owner about the proposed work.
A Party Wall Agreement is a general phrase many homeowners use when talking about consent, neighbour approval or the overall Party Wall process.
A Party Wall Award is the formal document prepared by surveyors when a neighbour dissents or does not respond. It sets out how the notifiable work should proceed.
Understanding the difference helps you know what stage your project is at and what action is required next.
The cost depends on the type of work, how many adjoining owners are involved and whether your neighbour consents or dissents.
Some projects only need Party Wall Notices. Others may require a Schedule of Condition or a Party Wall Award. Projects involving multiple owners, converted flats, basements or complex excavation may need more surveyor involvement.

You may need a Party Wall Agreement if your work affects a shared wall, boundary line or nearby foundations. This is common for loft conversions, extensions, basements and chimney breast removals.
Not exactly. Many people use “Party Wall Agreement” as a general term. A Party Wall Award is the formal document prepared by surveyors when there is dissent or no response.
Your neighbour can dissent to the notice, but this does not usually stop the work. It means the formal surveyor process begins and a Party Wall Award may be required.
You may need one if your loft conversion involves steel beams into a shared wall, raising a party wall, or other structural work affecting a party structure.
You may need one if your extension involves excavation close to a neighbouring property, work near the boundary line, or work affecting a shared structure.
If your neighbour does not respond within the required time, the matter is treated as a dispute under the Party Wall etc. Act 1996. A surveyor appointment may then be needed.
In most standard homeowner projects, the building owner carrying out the work pays the reasonable Party Wall surveyor fees.
Yes. If both owners agree, one impartial Agreed Surveyor can act for both sides and prepare the Party Wall Award.
It is best to start once your drawings or project details are ready. Leaving it too late can delay your planned construction start date.
No. Planning permission and Party Wall matters are separate. Even if your project has planning permission or is permitted development, you may still need to serve Party Wall Notices.
