Loft conversions, rear extensions, basement digs and chimney removals often trigger the Act. Serving a correct notice protects you legally and keeps the neighbours on side. (If the real disagreement is who owns the land at the boundary — a strip fenced off years ago, say — that’s adverse possession (Form ADV1), a different procedure.)
What is a party wall notice?
A formal notice telling adjoining owners about works covered by the Act — cutting into or altering a party wall (section 2), building a new wall at the boundary (section 1), or excavating within 3 or 6 metres of a neighbouring building and below its foundations (section 6).
Who needs it & when
Any building owner whose works affect a party wall/structure or involve nearby excavation. You serve it on each adjoining owner (including leaseholders and freeholders as applicable) before starting.
Deadlines & key rules
- 2 months notice for work to a party wall/structure; 1 month for new boundary walls and excavation works.
- The adjoining owner has 14 days to consent or dissent. No reply within 14 days is treated as a dispute.
- If a dispute arises, surveyor(s) are appointed to produce a binding Party Wall Award.
- The notice must describe the works and (for excavation) include plans showing depth and position.
How to serve it — step by step
- Identify which sections of the Act your works engage and all adjoining owners.
- Describe the works clearly, with plans/sections where required.
- Serve the notice on each adjoining owner, with the correct notice period.
- Deal with consent or dissent (and, if needed, the surveyor/Award process).
