Serving a party wall notice is a crucial step in any construction project that involves work on or near a shared boundary. Whether you're a homeowner or a developer, understanding the right time to serve a party wall notice is essential to avoid legal disputes and ensure a smooth project. In this blog, we'll provide expert insights into when and how to serve a party wall notice to protect your interests and maintain positive relationships with your neighbours.

What is a Party Wall Notice?

Before we delve into the timing of serving a party wall notice, let's briefly explain what it is. A party wall notice is a formal written communication that informs adjoining property owners of your intention to carry out certain construction work that may affect their property. The notice outlines the type of work, its potential impact, and the proposed start date.

Serving a Party Wall Notice: Key Timing Factors

1. Before Commencing Work: The general rule is to serve a party wall notice before you start any construction work that falls under the scope of the Party Wall etc. Act 1996. This includes work such as building on or near a shared wall, excavating near a neighbouring property, or altering a party wall.

2. Specific Timeframes: The Act requires you to serve the notice at least two months before the intended start date of the proposed work. This timeframe allows adjoining owners to review the notice, appoint their own surveyor if needed, and potentially raise concerns.

3. Complex Projects: For more complex projects, it's advisable to serve the notice even earlier than the minimum two-month period. This provides ample time for discussions, negotiations, and the appointment of surveyors if required.

4. Unforeseen Delays: Keep in mind that unforeseen delays can occur during the planning phase. If your project's start date changes after serving the notice, you should serve an updated notice to provide accurate information to your neighbours.

Why Timely Notice Matters:

1. Legal Compliance: Serving a party wall notice within the required timeframe ensures that you comply with legal obligations set out in the Party Wall etc. Act 1996. Failure to serve notice can lead to delays, legal disputes, and potential injunctions.

2. Neighbour Relations: Serving notice well in advance demonstrates respect for your neighbours' interests. It gives them time to understand the project, voice concerns, and potentially reach agreements that benefit both parties.

3. Avoiding Disputes: Clear communication and transparency reduce the likelihood of disputes arising later in the construction process. Serving a notice promptly fosters open dialogue with adjoining owners.

Steps to Serve a Party Wall Notice:

1. Prepare the Notice: Clearly outline the proposed work, its potential effects, and the proposed start date. Include your contact details for communication.

2. Serve the Notice: Hand-deliver the notice to your neighbours or send it by registered post. Retain proof of delivery, such as a receipt or acknowledgement of receipt.

3. Seek Professional Advice: If the project is complex or likely to impact neighbouring properties significantly, consider seeking advice from a qualified party wall surveyor to ensure the notice is accurate and compliant.


Serving a party wall notice is a critical step in any construction project, ensuring legal compliance and fostering positive relationships with neighbours. By serving the notice within the required timeframe and adhering to best practices, you'll contribute to a smoother construction process and a harmonious neighbourhood environment.

Remember that each project is unique, and seeking advice from a party wall surveyor can provide valuable insights tailored to your specific situation. When in doubt, consult professionals who specialize in party wall matters to ensure you're following the correct procedures.
