What is a Party Wall Agreement?
Hourican & Associates Ltd |
A Party Wall Agreement (also called a Party Wall Award) is a legally binding document prepared under the Party Wall etc. Act 1996. It sets out how proposed building works affecting a shared wall, boundary or nearby excavations will proceed, protects both owners, and provides a clear route to resolve issues.
When do you need a Party Wall Agreement?
- Works to a shared (party) wall – e.g. inserting steel beams for a loft conversion, removing a chimney breast, or adding a damp-proof course. (Serve a Section 2(2) Party Structure Notice)
- Building on or astride the boundary line – such as a new wall between properties. (Section 1 Notice)
- Excavations near a neighbour’s structure – within 3m (or in some cases 6m) and deeper than their foundations. (Section 6 Notice)
Example: For a terraced-house loft conversion in London, steel beams typically bear into the party wall. You must serve notice and, if the neighbour dissents, obtain an Award before works begin.
What happens if you don’t have a valid Party Wall Agreement?
- Injunctions & project stoppage – Neighbours can apply to court to halt works, causing significant delays.
- Legal costs – You may be ordered to pay the neighbour’s reasonable legal expenses.
- Damage disputes – Without a Schedule of Condition, it’s harder to prove pre‑existing defects and proportionate responsibility.
- Higher overall costs – Remedial works, redesigns and legal fees typically exceed the cost of doing it properly from the start.
Illustrative case: A rear extension commenced without notice led to an injunction, an 8‑week delay and several thousand pounds in combined legal and surveying fees, plus a compulsory retrospective Schedule of Condition.
If the agreement is incorrect or incomplete
Defective paperwork (wrong addresses, missing clauses, inadequate schedules, unclear access/working hours) can undermine enforceability, invite disputes, or leave the building owner exposed for any damage. Using an accredited party wall surveyor ensures statutory compliance and clarity.

Frequently Asked Questions
Typically 2–8 weeks from serving notice to agreeing the Award, depending on neighbour cooperation, complexity and response times set by the Act (usually a 14‑day response period plus survey/inspection time).
In most cases the building owner (doing the works) pays all reasonable Party Wall Surveyor fees, including for an agreed surveyor or each owner’s appointed surveyor.
Yes, but errors are common (wrong addresses, dates, works description). A professional surveyor ensures valid notices, reducing risk of disputes or delays.
If the neighbour signs the notice with no objections, you may proceed without a full Award. However, commissioning a Schedule of Condition is strongly recommended to protect both parties.
A Notice is the formal legal notification to your neighbour under the Act. An Agreement/Award is the binding document, usually prepared by surveyors, that sets out how the works will proceed and how risk is managed.
You risk an injunction stopping works, legal fees, strained neighbour relations, and difficulty defending any damage claims without a prior Schedule of Condition.
