What is a party wall notice?

When planning building work near a shared wall or boundary, you must serve a Party Wall Notice. It involves a formal, legal process, but it’s not as complicated as many homeowners might initially think, especially when a Party Wall Surveyor is involved. However, taking the time to understand what it is and when you need one can save you time, stress and costly disputes later down the line – trust us.

Short answer: A Party Wall Notice is a formal written document you must give your neighbour before starting building work that affects a shared wall, boundary or their foundations. It informs them of your plans and triggers the legal process under the Party Wall etc. Act 1996.

Breaking it down

A Party Wall Notice is a legal notice served by the homeowner (or their Party Wall Surveyor) to any neighbours who may be affected by proposed building work. Party Wall Surveyor Cost Guide.

It’s like giving your neighbour a heads-up, but legally – and it’s not optional. You’re required by law to serve the notice before you begin certain types of construction work.

Why a Party Wall Notice will be necessary

The Party Wall Notice is designed to protect both you and your neighbour’s assets by:

  • Making your plans clear
  • Giving them time to ask questions or appoint a surveyor
  • Ensuring all work is carried out safely
  • Putting legal protection in place if damage occurs
  • Preventing disputes by keeping the process transparent

Without the proper notice, you may not be legally allowed to start work. If you’ve started work without serving a notice, in serious cases, a court can order the work to be stopped, altered, or even pulled down, costing you time and money, so it’s important to go through the proper channels and follow the correct protocols.

The exact times you need to serve a Party Wall Notice

You must serve a Party Wall Notice when your project involves:

If you’re unsure, a Party Wall Surveyor can confirm whether your planned works fall under the Act.

The information your Party Wall Notice must include:

A valid Party Wall Notice needs to include:

  • Your name and address
  • A description of the proposed work
  • The planned start date
  • Drawings where appropriate
  • A clear reference to the Party Wall etc. Act 1996

If any of this is missing, the notice can be considered invalid, causing delays.

What happens once a Notice has been served

Your neighbour has 14 days to respond. They can:

This process ensures all work is carried out safely and legally.

Party Wall Notice vs Party Wall Agreement

A Party Wall Notice is not the same as a Party Wall Agreement – they’re two separate parts of the process.

  • The Notice is the document you serve at the start.
  • The Agreement (Party Wall Award) is the legally binding document prepared if your neighbour dissents.

A Party Wall Notice is simply the first step in the Party Wall Act process: a formal way to inform your neighbour of your plans and protect both properties. It’s not designed to cause conflict; it’s designed to prevent it. But if a conflict arises and you live in Surrey or London, Westville Associates can help.

I was recommended to use Westville Associates through a colleague to carry out a survey of a house we were looking to purchase. I couldn’t have been happier with the whole process. From start to finish, Simon was professional, punctual, through and gave good advice with issues that arose from the survey. I have and will continue to recommend Westville Associates to anyone wishing to carry out any surveys.

We used Wesville Associates for a full Building Survey for our property in Claygate after a recommendation from a friend. Simon was very personable, knowledgable and professional, and was able to work around our tight timeframe. We felt in good hands from the start!

“Westville Associates undertook a homebuyers report for us prior to the purchase of our flat in Wandsworth. The service from start to finish was exemplary. Simon booked us in, undertook the inspection and presented the report to us all within 7 working days which was appreciated as time was against us somewhat. The after sales care was also great as we had several questions about the property that were dealt with over the phone. Friendly, professional and prompt service. Would definitely recommend. Rob.”

I have worked in Surbiton and the surrounding areas as an agent for over 10 years and could not recommend Simon highly enough. He has a wealth of knowledge and goes above and beyond to ensure his clients fully understand the fantastic reports he creates, unlike many other surveyors who just send a confusing report without further explanation of key points. I am so pleased Simon has set up his solo venture - Westville Associates and will be recommending him to all of my clients.
