When You Need a Party Wall Surveyor
Most work on party walls or boundaries requires professional help. You need a party wall surveyor for:
- Building work on the existing party wall or boundary structures.
- Excavation within 3 m of your property.
- Changes to shared walls.
- Any work affecting foundations or the party structure.
- Early advice ensures you understand requirements before work begins.
Understanding Party Wall Agreements and the Party Wall Act
A party wall agreement protects both owners during building work, maintains good neighbour relations and follows legal procedures.
Party wall agreements typically cover:
- Description of the work.
- Approved methods.
- Working hours.
- Procedures to safeguard both parties.
What Does a Party Wall Surveyor Do?
A qualified surveyor handles legal aspects under the Act. Key responsibilities:
- Serve notice to your neighbour within 14 days.
- Prepare agreements to safeguard both parties.
- Monitor work for compliance.
- Resolve disputes if they arise.
Whether using a single agreed surveyor or two appointed surveyors, they act as your representative. They inspect existing walls, photograph conditions, and document defects. RICS and FPWS members follow strict standards, protecting homeowners from future claims.
How to Serve Notice for Building Work
You must serve a formal party wall notice under the Party Wall etc. Act 1996 before starting any work. The required notice period depends on the type of construction:
- Work on the boundary – minimum 1 month.
- Excavation within 3 m of a neighbour’s structure – 1 month.
- Alterations to a shared wall or party structure – 2 months.
In practice, party wall procedures can take time — especially if neighbours request their own surveyor. It’s advisable to serve notice at least 2–3 months before your planned start date to avoid delays.
If your neighbour does not respond within 14 days, a dispute is deemed to have arisen, and you must appoint a party wall surveyor. Either a single agreed surveyor or two appointed surveyors will then act to resolve matters formally.

Common Questions
Should I Hire a Party Wall Surveyor if My Neighbour is Doing Building Work?
Yes. If their work involves excavation within 3 m or affects a shared wall or boundary, they must serve notice. You can appoint your own surveyor for protection. A separate surveyor ensures fair treatment and resolves disputes professionally. If your neighbour doesn’t respond within 14 days, appoint a surveyor immediately. The dispute resolution process begins automatically.
What Are Notice Period Requirements When You Serve Notice?
- Two-month notices are required for:
- Alterations to existing party walls or boundary structures.
- New structures on the boundary line.
- Structural modifications to shared walls
- One-month notices are required for:
- Excavation within 3 m.
- Foundation works near the boundary.
- Basement construction affecting shared structures.
Count calendar days. If your neighbour doesn’t respond within 14 days, the dispute process starts.
Which Building Work Doesn’t Need a Party Wall Agreement?
Typically exempt:
- Internal renovations not affecting shared walls.
- Permitted development more than 3 m from the boundary.
- Surface repairs.
- Maintenance without structural changes.
- Landscaping away from boundaries.
Many homeowners wrongly assume their work is exempt. When unsure, get advice early to avoid problems.
Common Misconceptions About the Party Wall Act
Misconception: Neighbour Consent Means You Don’t Need to Serve Notice
Common Party wall misconceptions are Consent does not remove legal obligations. You must still serve notice even with written or verbal consent. Neighbours can choose not to appoint a surveyor, but notice is still required. The correct procedure is to:
- Serve notice.
- Allow the required period.
- Neighbour either consents or appoints a surveyor.
- Agree on methods and proceed legally.
Misconception: Neighbours Can Block Foundation Building Work
Neighbours cannot block legitimate works. The Act grants rights for work on boundaries. They can request fair compensation via their own professional. If parties can’t agree, surveyors issue a binding award. The surveyor resolves disputes and protects both owners.
Misconception: No Response Means Permission to Start Work
Silence is not consent. If your neighbour does not reply, you must appoint a surveyor. They can appoint their own or agree to a single surveyor. Formal documentation must be issued before work begins. Never assume silence allows you to proceed without following legal procedures. Surveyors protect both parties and resolve issues fairly.
