Removing a chimney breast is often described as an “internal alteration”, but in terraced and semi-detached homes it frequently affects a party wall—the shared wall between two properties. Where your works involve cutting into, altering, or relying upon that shared wall for support, the Party Wall etc. Act 1996 is likely to apply.
Which part of the Act applies?
Chimney breast removal commonly falls under Section 2 of the Act (rights to carry out certain works to an existing party wall or party structure). When you propose Section 2 works, the formal notice is served under Section 3 (often referred to as a “Party Structure Notice”).
The Party Wall process (Notice → Response → Award)
1) Notice (Section 3)
You must serve a Party Structure Notice at least 2 months before the intended start date. The notice should describe the works in a way a non-expert can understand, for example: what is being removed, what will remain, and what support will be installed.
2) Response
The adjoining owner has 14 days to respond in writing:
- Consent: they agree to the works as notified.
- Dissent: they do not consent (this does not automatically stop the works; it triggers the dispute procedure).
- No response: if they do not reply, the Act treats this as a dispute for process purposes.
3) Award (Section 10) if required
Where there is dissent (or no written consent), the matter proceeds under Section 10. Surveyor(s) are appointed and a Party Wall Award may be made. An Award is a formal document that sets out what work may proceed, how it should be carried out, and how the party wall matters are concluded.
What people misunderstand about chimney breast removal
A common misconception is: “It’s my chimney breast, so it’s my choice.” In practice, chimney breasts are often bonded into a party wall, or the party wall is used for support. The Act is concerned with the shared structure, not whether you can access the work from your side.
Common pitfalls that cause delay and cost
- Late notices: the neighbour’s first warning is builders arriving.
- Vague descriptions: “remove chimney breast” with no meaningful explanation.
- Changing scope mid-process: what was described in the notice is not what is later proposed.
- Over-reliance on contractor reassurance: “we do these all the time” rarely reassures an adjoining owner.

Helpful FAQs
Does a chimney breast removal always need a Party Wall Notice?
Not always, but if the party wall is cut into or relied upon, Section 2 is commonly engaged and a Section 3 notice is usually required.
If my neighbour dissents, can I still do the work?
Often yes, but the party wall matters must be concluded through Section 10, typically via an Award.
