When planning certain types of building work, the Party Wall etc. Act 1996 requires the property owner (the Building Owner) to serve formal notice on affected neighbours.
The Act typically applies where works involve:
- Building on or close to the boundary line.
- Alterations to an existing party wall or party structure.
- Excavations near a neighbour’s foundations, and deeper than their base level.
The purpose of the Act is not to block development, but to ensure such works are carried out fairly, with proper protections for both sides.
Common Works That Trigger the Act
Typical projects that fall under the Act include:
- New builds and extensions.
- Loft conversions requiring steel beams.
- Removing walls for through-lounges.
- Other works affecting shared walls or nearby foundations.
⚠️ Important: Failing to serve notice can lead to court action, including injunctions that halt your project.
Surveyors’ Roles
If the Act applies, surveyors may need to be appointed:
- The Building Owner Surveyor represents the owner undertaking the works.
- The Adjoining Owner Surveyor protects the neighbour’s interests.
- Alternatively, both parties can agree on a single impartial Agreed Surveyor.
I am qualified to act in any of these capacities.
What the Surveyor Does
The Building Owner’s Surveyor usually:
- Reviews drawings and proposals to identify the correct notices.
- Carries out a Land Registry search to confirm ownership details.
- Prepares and serves Party Wall Notices.
From there:
- If neighbours consent in writing, surveyor involvement normally ends.
- If they dissent or remain silent, surveyors will produce a Party Wall Award.
Fees
Party wall services are usually billed on a time-charge basis, as the work required can vary significantly depending on the complexity of each case.
