Removing a chimney breast can create valuable additional space inside a property, particularly where an unused fireplace takes up part of a bedroom, living room or other area.
However, removing a chimney breast is not simply a matter of taking down masonry and closing up the opening. Where the chimney is connected to or shared with a neighbouring property, the work may fall within the Party Wall etc. Act 1996.
You may own the chimney breast within your property, but that does not necessarily mean you can remove it without considering your neighbour’s rights. The structural work may also affect the adjoining property, particularly where the chimney stack, breast or supporting structure is shared.
At Charrette Law, we advise property owners on party wall matters, including chimney breast removal, Party Wall Notices, Party Wall Agreements and disputes between neighbours.
Does Removing a Chimney Breast Require a Party Wall Agreement?
It can.
Whether removing a chimney breast requires a Party Wall Agreement depends on the circumstances and the nature of the proposed work.
The Party Wall etc. Act 1996 applies to certain building works affecting party walls, party structures and structures close to neighbouring properties.
If the chimney breast forms part of a party wall, removing it may involve work to the party structure and could bring the works within the scope of the Act.
The situation can be more complicated where the chimney is shared between two properties or where its removal could affect the structural stability of the adjoining property.
For this reason, it is sensible to establish your legal position before starting the work, rather than assuming that removing an internal chimney breast is automatically permitted.
What Is a Party Wall?
A party wall is broadly a wall that stands on the boundary between two properties and is used by both owners.
Party wall matters can also involve certain structures and walls that are not simply ordinary dividing walls.
This is important when removing a chimney breast because the chimney may form part of a structure shared between neighbouring properties.
Our article on the Party Wall Act provides further information about when the legislation can apply to building works.
Why Can Removing a Chimney Breast Affect Your Neighbour?
A chimney breast may appear to be entirely within your property, but it can form part of a larger structural arrangement.
Removing it can potentially affect:
- The party wall.
- The chimney stack.
- Supporting masonry.
- The adjoining property’s chimney breast.
- Floors or ceilings.
- The structural stability of the building.
The exact risks depend on how the chimney has been constructed and whether it is shared with the neighbouring property.
This is why structural and party wall considerations should be dealt with before the chimney breast is removed.
Do You Need to Serve a Party Wall Notice?
Depending on the proposed works, you may need to serve a Party Wall Notice on your adjoining owner before starting work.
A Party Wall Notice formally informs the affected neighbour about proposed works that fall within the Party Wall etc. Act 1996.
The notice requirements depend on the type of work being undertaken.
It is important not to assume that because the work is being carried out inside your own property, the Party Wall Act cannot apply.
Where the proposed works affect a party wall or structure covered by the Act, the appropriate procedure should be followed.
Planning to Remove a Chimney Breast?
Before you start removing masonry, check whether the work raises party wall or structural issues.
Charrette Law can advise you on the Party Wall Act, notices and agreements relating to chimney breast removal. Contact our team before work begins to understand your legal position.
What Happens If Your Neighbour Consents?
If the relevant Party Wall Act procedure applies, your neighbour may consent to the proposed works.
However, it is important to distinguish between simply discussing the work with your neighbour and complying with the statutory Party Wall procedure.
A neighbour saying, “That’s fine,” verbally does not necessarily provide the same protection as following the correct legal process.
Where the Act applies, obtaining appropriate written documentation can provide greater clarity for both property owners.
What If Your Neighbour Objects?
Your neighbour has rights under the Party Wall etc. Act 1996.
If they do not consent to the proposed works, this does not necessarily mean that the chimney breast cannot be removed.
Depending on the circumstances, the parties may need to appoint Party Wall Surveyors to deal with the matter.
A surveyor may consider the proposed works, prepare or agree a Party Wall Award and address issues concerning the adjoining property.
Our article on Party Wall Surveyors explains what a surveyor does and why one may be required when building works affect a neighbouring property.
What Is a Party Wall Award?
A Party Wall Award is a formal document dealing with works covered by the Party Wall etc. Act 1996.
Depending on the circumstances, it may deal with:
- The nature of the proposed works.
- How and when the work can be carried out.
- Protective measures.
- Access arrangements.
- The condition of the adjoining property.
- Relevant rights and responsibilities.
A Party Wall Award can provide a framework for carrying out works while helping protect the interests of both property owners.
What About Structural Calculations?
Removing a chimney breast can involve important structural considerations.
The chimney breast may support masonry above it or be connected to the chimney stack or other structural elements.
A structural engineer may therefore need to assess the proposed removal and specify appropriate support.
This is separate from the Party Wall process.
Structural calculations and Party Wall compliance are not the same thing.
You may need structural calculations while also needing to comply with the Party Wall Act.
Do You Need Planning Permission to Remove a Chimney Breast?
Planning permission and party wall requirements are separate matters.
Removing an internal chimney breast may not necessarily require a planning application, but the circumstances of the property and nature of the proposed works should be considered.
Additional planning considerations may arise where the property is listed or located within a conservation area, for example.
Even where planning permission is not required, you may still need to consider:
- Building Regulations.
- Structural safety.
- Party Wall requirements.
- Other property restrictions.
Homeowners should therefore avoid treating planning permission, Building Regulations and the Party Wall Act as interchangeable requirements.
Planning Permission Is Not the Same as Party Wall Consent
Receiving planning permission does not remove your obligations under the Party Wall etc. Act 1996.
Likewise, complying with the Party Wall Act does not automatically mean that all other building or planning requirements have been satisfied.
Each requirement needs to be considered separately.
Removing a Chimney Breast in a Terraced or Semi-Detached House
Party wall issues can be particularly important in terraced and semi-detached properties because these properties commonly share walls and structural elements with neighbouring homes.
A chimney may also have been constructed as part of a shared arrangement, even if the chimney breast appears to be located entirely within your property.
Before removing a chimney breast, it is sensible to establish:
- Whether the wall is a party wall.
- Whether the chimney is shared.
- Whether the proposed works affect the party structure.
- Whether a Party Wall Notice is required.
- Whether your neighbour needs to appoint a surveyor.
- What structural support will be required.
What Happens If You Remove the Chimney Breast Without Following the Party Wall Process?
Starting work without complying with the Party Wall Act where it applies can create problems with your neighbour.
Your neighbour may raise concerns about:
- Damage to their property.
- Structural stability.
- Cracking.
- Dust or debris.
- Access.
- The way the works are being carried out.
Disputes can become costly and time-consuming, particularly if concerns only arise after work has already started.
It is therefore generally better to deal with party wall matters before construction begins.
If work has already started or the chimney breast has already been removed, obtaining legal advice promptly can help you understand what options may be available.
Removing a Chimney Breast and Your Party Wall Agreement
There is no single answer to whether every chimney breast removal requires a Party Wall Agreement.
The answer depends on the property, construction of the chimney, relationship between the properties and precise nature of the proposed work.
This is why advice based on your specific circumstances is preferable to relying on general assumptions.
At Charrette Law, we can help property owners understand whether the Party Wall Act applies and what steps should be taken before work begins.

Frequently Asked Questions
Do I need a Party Wall Agreement to remove a chimney breast?
It depends on the circumstances. If the proposed removal affects a party wall or party structure covered by the Party Wall etc. Act 1996, the Act’s procedures may apply.
Can I remove a chimney breast without telling my neighbour?
You should first establish whether the proposed works fall within the Party Wall Act. If they do, the appropriate notice and procedure may need to be followed before work begins.
Does removing a chimney breast affect a party wall?
It can. The chimney may form part of or be connected to a party structure, and removing it may affect the structural arrangement of the building.
Do I need a structural engineer to remove a chimney breast?
A structural assessment may be necessary because removing a chimney breast can affect supporting masonry or other structural elements. The requirements will depend on the construction of the property and the proposed works.
Is removing a chimney breast the same as removing a chimney stack?
No. A chimney breast is the portion projecting into a room, while the chimney stack is the external structure above the roof. Removing one does not necessarily mean the other can also be removed.
What if my neighbour objects to the chimney breast removal?
If the Party Wall Act applies and your neighbour does not consent, the relevant party wall procedure may need to be followed, potentially involving Party Wall Surveyors and a Party Wall Award.
Can Charrette Law help with chimney breast removal?
Yes. Charrette Law can advise on Party Wall Notices, Party Wall Agreements, Party Wall Awards and disputes arising from proposed chimney breast removal.
