Do I Need a Party Wall Agreement If I’m Not Working Directly on a Party Wall?

Many homeowners and landlords are aware of the Party Wall etc. Act 1996, often thinking it applies only when physically working on a party wall (like the wall between terraced or semi-detached houses). But the Act casts a wider net than you might expect.


What’s the Purpose of the Party Wall Act?

At its core, the Act is about maintaining good relations between neighbours during building works that could affect shared or adjoining structures. It promotes voluntary agreement but also provides a formal dispute resolution process where needed — by appointing surveyors to act impartially and make legally binding Awards.


Is My Project Covered by the Act?

Even if you’re not working directly on a party wall, your project may still be notifiable under the Act. Here’s why:

  • The Act applies to work on or near boundaries, including excavations and work that affects shared structures like garden walls or chimney stacks.
  • You might need a Party Wall Agreement even if the work involves repairing, digging, or modifying a structure close to or on the boundary.
  • Many smaller projects don’t involve a designer or architect, so homeowners often miss this important step.

Examples of Work Covered by the Act

Some common notifiable works include:

  • Building a new wall on or near a boundary
  • Inserting a damp-proof course between two properties
  • Installing flashing or other weatherproofing details
  • Cutting into a wall to install a beam or lintel
  • Repairing or rebuilding parts of a shared wall
  • Removing projections like chimney breasts or flues
  • Excavating within 3 or 6 metres of a neighbouring building (depending on depth)

✏️ Note: Minor DIY works like drilling for a shelf or plastering are not notifiable.


I’ve Got Planning Permission — Isn’t That Enough?

No — and here’s the key misconception.
Planning Permission and Building Regulations do not cover Party Wall matters. Local Authorities don’t handle neighbour agreements or carry out pre-works surveys of neighbouring properties. That’s why a Party Wall Notice and potentially a Party Wall Award are essential steps in their own right.


What Should I Do If My Work Is Notifiable?

Your next step is to serve a Party Wall Notice to any Adjoining Owner affected by the works. This formal notice sets the legal process in motion and gives neighbours the opportunity to agree or appoint a surveyor.

👉 Top Tip:
Speak to your neighbour first.
There’s no legal requirement to give them a heads-up, but an informal conversation can go a long way toward reducing friction, speeding up agreement, and avoiding unnecessary surveyor appointments.
