The Party Wall Process: Timing, Responsibilities, and Avoiding Costly Delays

Key Takeaways:

A party wall is a shared structure, typically built on the boundary line between two properties. Governed by the Party Wall Act 1996, understanding your rights and responsibilities helps avoid disputes and ensures a smooth building process.

What is a Party Wall?
A party wall is a shared structure between neighbouring properties. There are two types:

  • Type A: A wall that sits directly on the boundary line, dividing properties equally.
  • Type B: A wall that is entirely on one owner’s land but acts as a boundary.

It’s important to remember that party walls also include the foundations, not just the visible structure above ground. Understanding the difference between a party wall and a party fence wall is crucial for avoiding confusion.

Property Owners’ Responsibilities
Both property owners are responsible for the upkeep and repair of the party wall, as per legal guidelines. Clear communication with your neighbour is essential before any construction begins, especially when dealing with shared walls.

Under the Party Wall Act, you must notify your neighbour at least two months before starting any work. Failure to notify them could lead to legal complications.

How Long Should You Leave for the Party Wall Process?

  • Notice Period: You must give notice two months before any work starts.
  • Neighbour Responses: You’ll usually get a response within 14 days, but delays can occur if your neighbour is uncooperative.
  • Surveyor Involvement: If disagreements arise, appointing surveyors can take weeks, adding months to your project timeline.
  • Potential Delays: Be prepared for the process to take four to six months—including time for neighbour responses, disputes, and the appointment of surveyors. The timeline depends on the complexity of the agreement and communication between neighbours.

Party Wall Notices Explained
Party wall notices must be detailed, specifying:

  • Type of work (e.g. extension or excavation).
  • Start date and duration of work.
  • Neighbours’ details on both sides.

The notice is valid for one year, so if work doesn’t start within that period, you’ll need to re-serve the notice. Always send notices via first-class post for a clear paper trail.

Costs Involved
Costs for party wall work can range from a few hundred to several thousand pounds, depending on the complexity and whether there’s a dispute. Surveyor fees and legal paperwork can add to the total cost.

When a Disagreement Occurs
If a neighbour disagrees, a Party Wall Award must be issued by an independent surveyor. This process can take weeks or months, depending on the number of surveyors involved. If all parties agree on a single surveyor, the process can be much faster—often completed in a few days.

Don’t Wait—Plan Ahead
The earlier you initiate the party wall process, the smoother the project will run. Consider speaking with your neighbour before serving the notice to avoid misunderstandings and set expectations clearly. Always appoint a surveyor early, especially if disputes arise.
