How to tell your neighbour about your building plans

Why it matters

A party wall notice is a legal document. Arriving cold, it can read like a threat. The same information delivered in person feels like what it is: a courtesy that the law happens to formalise.

Neighbours who feel informed tend to:

• reply within the 14 days instead of letting the deadline pass
• consent, or agree to share one surveyor, rather than appointing their own
• raise worries early, while they are easy to deal with

What to show them

• The drawings, or at least the parts that affect them: the shared wall, the boundary and the foundations.
• Roughly when you hope to start, and how long the noisy stages will last.
• Who your builder is.

What to explain

• That a notice will follow. It is a legal requirement, not a sign of trouble.
• Their choices. They can consent, share one surveyor with you or appoint their own.
• Who pays. If surveyors are needed, you will normally meet the reasonable fees for both sides. Saying so early removes a common worry.
• How their home will be protected. A record of its condition before work starts makes sense whatever they decide.

What not to do

• Do not ask them to sign anything there and then. Give them time.
• Do not play the work down. If it involves cutting into the shared wall, say so.
• Do not let a builder's start date put pressure on them. Managing the timetable is your job.

Then put it in writing

After the conversation, serve the notice properly. A short covering letter that recaps what you discussed, with a simple reply form, makes the paperwork feel familiar rather than official. See how to serve a notice.
