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: 

• Start dates being pushed back 

• Contractors becoming unavailable or re-booking 

• Knock-on costs across the project 

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. Early involvement also gives adjoining owners space to consider the proposals without feeling pressured. 

When to Book Your Contractor 

It’s sensible to wait to formally book your contractor until your Party Wall Surveyor has: 

• Reviewed all drawings 

• Served the notices 

• Given you a realistic timeframe for finalising the Award 

This avoids committing to a start date that the statutory process can’t meet. 

That said, it helps to have your intended contractor identified and available. Surveyors sometimes need input on method statements, sequencing, temporary works or access arrangements. Having a contractor on standby for these discussions makes the process smoother. 

Key Advantages of Starting Early 

• Lower risk of delays 

• Better chance of keeping your chosen contractor 

• Fewer unexpected costs 

• Clear expectations for everyone involved 

  Final Thoughts 

  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.
