Do you need a Party Wall Notice?

A party wall notice is a formal written notice that a property owner gives to a neighbour when they plan to do building work that might affect a shared wall, structure, or boundary.

You must serve a party wall notice if you’re planning:

• Work on a shared wall (a “party wall”) between terraced or semi-detached houses.

• Building up to the boundary line (for example, building an extension or loft conversion).

• Excavating near a neighbour’s property (e.g., digging foundations within 3 or 6 metres depending on depth).

The notice includes:

• Your name and address.

• A clear description of the work.

• When you plan to start.

You must give your neighbor:

• 2 months’ notice before work begins for most structural work.

• 1 month’s notice for smaller works like excavation.
