When Should You Put a Party Wall Agreement in Place?

Getting the Timing Right

A common question we hear from homeowners and small developers is when to start the Party Wall process. It usually comes up once planning permission is sorted, building control drawings are ready, and the pressure to begin construction starts to build. At that point, time becomes tight and the risk of delays increases.

Why Leaving It Late Causes Problems

If Party Wall notices are only served at the last minute, surveyors are left with limited time to review the drawings, speak with neighbours, and follow the statutory timelines set out in the Party Wall etc. Act 1996. These timelines can’t be shortened, which often leads to:

The Ideal Time to Bring a Surveyor In

The best time to involve a Party Wall Surveyor is as soon as your building regulation and structural drawings are finished. These drawings give the surveyor enough information to work out which sections of the Act apply and to serve the right notices in good time.

Begin the Party Wall process as soon as your structural drawings are ready. Hold off booking your contractor until your surveyor confirms a realistic timeline, but keep them close enough to answer any technical questions. This approach keeps the project organised and prevents avoidable setbacks.
