Party Wall Agreement Rapid Guide

Today, we’re diving into party wall agreements—what they are, when you need them, how long they last, and whether you can handle it on your own. Let’s get into it!


What is a Party Wall Agreement?


A party wall is a shared wall between two properties, typically found in terraced or semi-detached houses. It can also refer to a floor that separates two flats.

A party wall agreement is a legal contract between you and your neighbour. It outlines how any construction work on the shared wall or boundary will be managed. This agreement helps protect both you and your neighbour’s property, ensuring that work is done safely and that no damage occurs.


When Do You Need a Party Wall Agreement?


You’ll need a party wall agreement if your work involves the shared wall or boundary with your neighbour. This could include:


• Building a new wall
• Making changes to an existing wall
• Carrying out excavations near or beneath the foundation of a shared wall

Even if the work is only affecting your side, you still need the agreement before starting. You must give your neighbour two months’ notice before beginning the work. While a party wall agreement won’t stop your neighbour from carrying out work, it will ensure that everything is done according to an agreed timeline and in a way that avoids disputes.


How Long Does a Party Wall Agreement Last?


A party wall agreement is valid for as long as the wall remains intact. If the wall gets damaged or demolished, a new agreement must be created. The terms of the agreement can also outline a specific time frame for the completion of the work.


Now you know what a party wall agreement is and when you need one!
