If you’re planning major home renovations, you may be wondering whether a Party Wall Agreement is required, particularly when removing a chimney breast or inserting steel beams. Understanding your legal obligations under the Party Wall etc. Act 1996 is crucial to avoid disputes with neighbours and ensure your project runs smoothly.
In this blog, we’ll explain when a Party Wall Agreement is necessary, how it applies to chimney breast removal and steel beam insertion, and what steps you need to take to stay compliant.
What is a Party Wall Agreement?
A Party Wall Agreement is a legally binding document that sets out the rights and responsibilities of property owners when building works affect a shared wall (the party wall) or structure. This agreement is required under the Party Wall etc. Act 1996, which is designed to protect the interests of all parties involved, including neighbouring property owners.
When is a Party Wall Agreement Needed?
You will need a Party Wall Agreement if your renovation work involves:
- Work on an existing party wall or structure shared with a neighbour
- Building new walls on or near the boundary line between properties
- Excavating near a neighbouring property’s foundations
Projects like removing chimney breasts and inserting steel beams often fall under these categories, meaning a Party Wall Notice must be served and an agreement obtained from such as Simmons Taylor Hall.
Do You Need a Party Wall Agreement for Removing a Chimney Breast?
In many cases, chimney breast removal will require a Party Wall Agreement. Here’s why:
- Shared Structure: If the chimney breast is part of a party wall (a wall shared between two properties), removing it will affect the structural integrity of the wall. Any alteration to the party wall requires notifying the adjoining owner.
- Structural Impact: Removing a chimney breast usually involves inserting steel supports (such as RSJs or lintels) to bear the load. This could affect the strength and stability of the wall, making a Party Wall Agreement necessary.
- Possible Damage Risk: There is a risk of causing damage to the adjoining property, such as cracks or structural movement, during the removal process. A Party Wall Agreement helps clarify responsibilities and protections in case issues arise.
If the chimney breast is located solely within your property and does not form part of a party wall, you may not need an agreement. However, it’s always advisable to consult a qualified Party Wall Surveyor to assess the situation.
Do You Need a Party Wall Agreement for Inserting Steel Beams?
Similarly, inserting steel beams as part of structural renovations often requires a Party Wall Agreement. Here’s why:
- Support to Party Wall: Steel beams may be inserted to support the structure when removing internal walls or chimney breasts. If the beam bears on or affects the party wall, notification to the adjoining owner is required.
- Excavation Work: Inserting steel beams could involve foundation work or excavation near a neighbouring property. Under the Party Wall etc. Act, excavation within three or six metres of an adjoining structure, depending on depth, mandates serving a Party Wall Notice.
- Potential Structural Changes: Any changes that impact the load-bearing nature of a shared wall can affect both properties. A Party Wall Agreement sets out how these changes will be managed safely.
What Are the Steps to Obtain a Party Wall Agreement?
1. Serve a Party Wall Notice
You must formally notify your neighbour(s) in writing, providing details of the planned works, such as chimney breast removal or steel beam insertion. This is called a Party Wall Notice and must be served at least two months before work begins.
2. Wait for a Response
Neighbours have 14 days to respond. They can:
- Give consent to the works
- Refuse consent, triggering the need for a Party Wall Surveyor
- Ignore the notice, which will be treated as dissent after 14 days
3. Appoint a Party Wall Surveyor
If your neighbour does not consent, you will both need to appoint a surveyor (or agree on one surveyor acting for both parties). The surveyor will draw up a Party Wall Award, detailing how the work should be carried out, timelines, and measures to protect both properties.
4. Agree on Terms
The Party Wall Award will specify working hours, methods to prevent damage, and responsibilities for repairs if damage occurs. Once agreed, both parties must adhere to the terms.
Consequences of Not Getting a Party Wall Agreement
Skipping the Party Wall process can result in several problems:
- Legal action from neighbours
- Delays in your renovation project
- Increased costs if disputes arise
- Liability for damage to the adjoining property
Obtaining a Party Wall Agreement helps safeguard against these risks, ensuring transparency and legal protection.
Common Questions About Party Wall Agreements
How much does a Party Wall Agreement cost?
Costs vary depending on the complexity of the work and whether one or two surveyors are involved. Typically, the building owner (the person carrying out the work) pays the surveyor fees.
Can I start work without my neighbour’s consent?
No. If your neighbour does not consent, you must go through the surveyor process before starting work.
What happens if my neighbour ignores the notice?
If your neighbour fails to respond within 14 days, it is treated as dissent, and you will need to appoint a surveyor to proceed.
Is it worth speaking to my neighbour first?
Yes. It’s always advisable to discuss your plans informally before serving a Party Wall Notice. This can help avoid misunderstandings and make the process smoother.

If you’re planning to remove a chimney breast or insert steel beams, it’s essential to understand whether a Party Wall Agreement is required. In most cases, if the work affects a shared wall or involves structural changes, notifying your neighbour and obtaining an agreement is a legal obligation.
Consulting an experienced Party Wall Surveyor ensures you stay compliant, minimise disruption, and protect both your property and your neighbour’s. Proper planning and open communication can help your renovation project proceed smoothly and without costly disputes.
