The Party Wall Act Explained — A Homeowner's Guide

What the Party Wall Act 1996 Covers

The Party Wall etc. Act 1996 is designed to prevent disputes between neighbours when building work affects shared structures. It covers three main areas:

• Excavations within 3m: Any excavation within 3 metres of a neighbour's foundation or building
• Work on shared walls: Any work on or near a wall that stands on the boundary between properties
• New walls on boundary: Building a new wall on the boundary line

When You MUST Serve Notice

You must serve formal notice at least 2 months before structural work begins. For excavations, notice must be served at least 1 month before starting work. The notice must be served on all affected neighbours — this includes freeholders, leaseholders, and sometimes mortgagees.

Types of Party Wall Notice

There are three types of notice under the Act:

• Party Structure Notice: For work on an existing party wall (cutting in beams, raising the wall, etc.)
• Line of Junction Notice: For building a new wall on the boundary
• Adjacent Excavation Notice: For excavating within 3-6 metres of a neighbour's foundation

The Party Wall Agreement Process

Once notice is served, your neighbour has options:

1. Consent: They can agree in writing, and you can proceed
2. Dissent: If they dissent, they must appoint a surveyor within 14 days
3. No response: If no response after 14 days, you can appoint a surveyor on their behalf

If surveyors are appointed, they will prepare a "Party Wall Award" — a legal document setting out how work will be carried out, including access arrangements and protection for both properties.

Costs of Party Wall Surveyors

Party wall surveyor fees typically range from £700 to £1,500 per property. If both parties appoint their own surveyors, costs can reach £1,500-£3,000 total. The building owner who initiates the work always pays these costs — this is non-negotiable under the Act.

Can Neighbours Refuse?

No — neighbours cannot refuse you the right to carry out work under the Party Wall Act. However, they can:

• Appoint their own surveyor to ensure their property is protected
• Request specific conditions in the Party Wall Award
• Negotiate for compensation if the work causes damage or disturbance

What Happens If You Ignore the Act?

Ignoring the Party Wall Act can result in:

• Injunctions stopping your work
• Personal liability for any damage caused
• Difficulty selling the property (solicitors will ask about party wall compliance)
• Having to undo completed work
