Party Wall Agreement: A Simple Guide

If you’re planning building work near a shared wall or boundary, you may need a party wall agreement to stay within the law and avoid disputes.

What Is a Party Wall Agreement?

A party wall agreement is a legal document that confirms your neighbour has been informed about and agrees to your building plans. It applies when work is planned on or near a shared wall, known as a party wall. This could be between terraced or semi detached houses, or even a garden wall built along a boundary.

When Is It Needed?

You must serve written notice if you plan to:

  • Build on or near a boundary
  • Alter or repair a shared wall
  • Dig foundations close to a neighbour’s property

Minor tasks like plastering or shelving usually do not require a formal agreement.

The Party Wall Notice

A party wall notice must be given in writing. Your neighbour has 14 days to respond. If they agree, you may proceed. If they object or do not reply, you must appoint a party wall surveyor to prepare a legal document called a Party Wall Award.

The notice period is one month for excavation or new boundary walls, and two months for work to an existing party wall. You then have up to 12 months to start the work.

Surveyors and Costs

If surveyors are needed, the person carrying out the work typically pays. Costs vary but usually range from £150 to £200 per hour. A full Party Wall Award often costs around £1,000. Simple Surveys fees are a fraction of this at around the £300 mark all in.

Keep Things Friendly

Before serving formal notice, speak to your neighbour. Explain the work and offer contact details for your builder or surveyor. A simple conversation can help avoid unnecessary conflict.

Summary

Always follow the Party Wall Act to prevent legal issues and delays. For help, contact a local chartered surveyor with experience in party wall matters.
