Party Wall Agreements in England and Wales: What Buyers and Owners Should Know

If you plan building work near a neighbour, the Party Wall etc. Act 1996 may require you to give notice before you start. It applies in England and Wales and covers work on or near shared walls, and some excavation near neighbouring buildings.

This Banke UK guide explains the basics, who does what and what to ask a surveyor or solicitor. It is not a substitute for professional advice on your own project.

What the Act Covers

The Act sets out a process for certain types of work: building on or at the boundary line between properties, work to a shared party wall, and some digging close to a neighbouring building. Not every project falls within it, so check with a surveyor.

Why It Matters to a Buyer

If the seller has already extended or converted the property, ask whether notices were served and whether any party wall award exists. Your solicitor can raise this as part of the enquiries.

The Basic Process

  • The building owner serves a written notice on the adjoining owner.
  • The neighbour may consent, or dissent and a surveyor is appointed.
  • A party wall award can record the work, access and condition of the neighbouring property.

Costs and Timing

Costs depend on the surveyors involved and the project. We do not quote figures here. Ask for a written fee estimate and a timeline before you appoint anyone.

Other Approvals Still Apply

A party wall agreement is separate from planning permission and building regulations approval. Each has its own rules, and one does not replace the others.

Common Mistakes

  • Assuming good relations with a neighbour make notice unnecessary.
  • Starting work before the notice period has run.
  • Not recording the neighbour property condition beforehand.
  • Confusing party wall rules with planning rules.
