Planning building works near a shared wall or boundary? If your project has hit a snag over party wall concerns, it might be time to call in a professional. This 2025 guide breaks down when and why a Party Wall Surveyor could be the key to unlocking your progress.
What Is a Party Wall?
A party wall is any wall, floor, or boundary shared with a neighbouring property. Most commonly found between terraced and semi-detached homes, party wall rules can also apply to detached houses—for example, where garden walls or boundary lines are shared.
If your works come within 3 metres of a party wall, UK law requires you to serve a formal Party Wall Notice to the affected neighbour(s) at least 2 months before starting construction.
Do I Need a Party Wall Surveyor?
You can draft and serve a notice yourself, but hiring a Party Wall Surveyor early in your project is the best way to:
- ✅ Ensure you’re legally compliant
- ✅ Avoid project delays
- ✅ Reassure your neighbours
- ✅ Protect yourself from disputes or false damage claims
If a disagreement arises—or your neighbour ignores the notice—you’re legally required to appoint a surveyor to resolve it.
One Surveyor or Two?
In most cases, you and your neighbour will agree to use a single surveyor, known as an Agreed Surveyor. If you can’t decide together, each party can appoint their own. If your neighbour fails to appoint one, you can do it on their behalf—legally.
You cannot act as your own surveyor, even if you’re qualified.
What Does the Surveyor Do?
Once appointed, the Party Wall Surveyor will prepare a legally binding document called a Party Wall Award, which includes:
- 🔧 Details of the proposed works
- 🕒 Working hours, access requirements, and timeline
- 💰 Surveyor’s fees and cost allocations
This award outlines exactly how the work should be carried out to protect both properties and limit disruption.
What If I Disagree With the Party Wall Award?
If you’re unhappy with the contents of the award, you have the right to appeal to a county court. You must submit an appellant’s notice within 14 days of receiving the award, clearly stating your reasons.
Can I Access My Neighbour’s Property?
Yes—but with notice. Your neighbour must allow surveyors and workers access to their property during normal working hours, provided you give at least 14 days’ notice (unless there’s an emergency).
