Party Wall Surveyors: When Do You Need One?
Party wall surveyors play a crucial role in London building projects. At Hampstead Surveyors, we act as party wall surveyors for building owners and adjoining owners, ensuring fair treatment and legal compliance throughout construction projects affecting shared boundaries.
What Does a Party Wall Surveyor Do?
Party wall surveyors appointed under the Party Wall Act 1996:
- Prepare party wall awards documenting agreed works
- Conduct condition surveys of neighboring properties
- Ensure compliance with the Act's provisions
- Resolve disputes between building and adjoining owners
- Monitor construction work
- Assess and resolve damage claims
When Do You Need a Party Wall Surveyor?
After Serving Party Wall Notices
Once you serve party wall notices, neighbors have 14 days to respond. If they dissent or don't respond, surveyors must be appointed.
Types of Surveyor Appointments
- Agreed Surveyor: One surveyor acts for both parties (most cost-effective)
- Two Surveyors: Each party appoints their own surveyor who work together
- Third Surveyor: Appointed by the first two to resolve disputes
The Party Wall Surveyor Process
1. Surveyor Appointment
Building owners can appoint any qualified surveyor. If neighbors dissent but don't appoint their own surveyor, building owners appoint one on their behalf (at building owner's cost).
2. Initial Meeting and Inspection
Surveyors meet to discuss proposed works, inspect the properties, and establish a working relationship.
3. Condition Survey
Comprehensive survey of neighboring property documenting pre-construction condition with photographs and detailed descriptions.
4. Party Wall Award Preparation
The Award is a legal document setting out:
- Description of proposed works
- Working hours and access rights
- Protection measures required
- Dispute resolution procedures
5. Construction Monitoring
Surveyors have rights to inspect works during construction ensuring compliance with the Award.
6. Final Inspection and Resolution
After completion, final inspection compares property condition to original survey. Any construction damage must be rectified by the building owner.

Common Party Wall Surveyor Questions
Can I act as my own party wall surveyor?
Legally yes, but highly inadvisable. Party wall matters require technical knowledge, impartiality, and professional expertise.
What if I disagree with my appointed surveyor?
Surveyors must act impartially under the Act. If serious concerns arise, the third surveyor provides oversight and resolution.
How long does the party wall process take?
From notice service to Award: typically 4-8 weeks for straightforward cases, longer for complex projects or if disputes arise.
