Thinking about removing a chimney breast from your property? It’s a big structural job — and depending on your circumstances, you may need a Party Wall Agreement before you begin.
This guide explains when the Party Wall etc. Act 1996 applies, why an agreement matters, and how to make sure your project runs smoothly and legally.
What Is a Party Wall Agreement?
A Party Wall Agreement is a legally binding document between neighbours who share a wall, boundary, or structure. It:
- Sets out the planned works.
- Protects both properties from potential damage.
- Appoints an independent surveyor (if required) to ensure the work is carried out fairly and safely.
The agreement prevents disputes and provides a clear framework if issues arise.
Do You Need a Party Wall Agreement for Chimney Removal?
You will usually need one if:
- Your chimney breast is attached to a shared wall with your neighbour.
- You need to carry out excavations within 3 metres of your neighbour’s property and deeper than their foundations.
- Your chimney stack extends above your roofline and overhangs a neighbour’s property.
If the chimney is entirely within your property and not connected to a shared wall, you may not need a Party Wall Agreement. But building regulations, planning permissions, and neighbour notification may still apply.
How Do You Get a Party Wall Agreement?
- Serve Notice – You must send your neighbour a formal Party Wall Notice, ideally at least two months before the work begins.
- Wait for Response – Your neighbour has 14 days to consent, dissent, or ignore the notice.
- If they consent, you can proceed.
- If they dissent or don’t reply, a surveyor will need to prepare a Party Wall Agreement.
- Surveyor’s Role – The appointed surveyor(s) ensure the work complies with the law and that both properties are protected.
Why an Agreement Matters for Chimney Breast Removal
Removing a chimney breast involves structural changes that can affect both your home and your neighbour’s. Risks include:
- Cracks in walls and ceilings.
- Roof damage and leaks.
- Compromised structural support if beams or reinforcements aren’t installed properly.
- Liability for repairs to your neighbour’s flooring, plaster, or external walls.
A Party Wall Agreement provides a safety net, ensuring all parties are protected and disputes are avoided.
