Why Do You Need a Party Wall Surveyor?
Understanding your rights and responsibilities under the Party Wall etc. Act 1996
If you're planning building work that affects a shared wall or boundary with a neighbour, you may have heard you’ll need a Party Wall Surveyor.
But what exactly do they do – and why are they important?
Here’s everything you need to know.
What Is a Party Wall?
A Party Wall is any wall that sits on the boundary between two properties and is shared by both.
Common examples include:
- The wall between two terraced or semi-detached houses
- A garden wall built astride the boundary line
- Floors between flats
Even if you legally own your property, you can’t just start altering a party wall without following the proper legal process – which is where the Party Wall etc. Act 1996 comes in.
When Does the Party Wall Act Apply?
The Act applies if you’re planning works such as:
- Building on or near the boundary line
- Cutting into a party wall (e.g. to insert a beam)
- Raising, lowering or demolishing part of a party wall
- Excavating within 3–6 metres of a neighbouring structure (depth depending)
In these situations, you must serve your neighbour with a *Party Wall Notice*. If they agree in writing, you can proceed. If they dissent (or don’t respond), a Party Wall Award needs to be drawn up – and that’s where a Party Wall Surveyor comes in.
What Does a Party Wall Surveyor Do?
A party wall surveyor is an impartial professional (not someone who takes your side) appointed to:
- Assess the planned work
- Protect the interests of both property owners
- Record the condition of neighbouring property before work begins (a “Schedule of Condition”)
- Resolve disputes and draft the legally binding *Party Wall Award*
They ensure that work is carried out safely, that your neighbour’s property is protected, and that any damage is properly handled.
Can You Use Just One Surveyor?
Yes – if both you and your neighbour agree, you can appoint a single Agreed Surveyor to act for both sides. If not, each party can appoint their own surveyor, and the two will work together.
Do I Have to Use a Party Wall Surveyor?
Not always – if your neighbour consents in writing to the work, and no issues arise, a surveyor may not be necessary. However:
- If there’s any dispute
- If your neighbour doesn’t reply
- Or if the work is complex…then appointing a surveyor is the best way to stay compliant with the law and avoid future conflict.
Why It’s Worth It
Party wall surveyors help:
- Avoid legal disputes
- Minimise the risk of costly damage claims
- Maintain good neighbourly relationships
- Keep your project on schedule and legally sound
Cutting corners here can lead to delays, fines, or even court orders to stop your work. It’s not worth the risk.
If you’re undertaking any work near a boundary or shared structure, don’t ignore your party wall responsibilities. A qualified surveyor will help you navigate the process smoothly and protect everyone involved.
