The “6 metre” category surprises homeowners because six metres does not feel close. However, where excavation is deeper, the zone of influence can extend further than you expect.
Which part of the Act applies?
This sits within Section 6 of the Act, commonly associated with Section 6(2) (the deeper excavation category within 6 metres).
The Party Wall process (Notice → Response → Award)
1) Notice (Section 6)
Serve a Section 6 notice at least 1 month before excavation begins.
2) Response (14 days)
Consent, dissent, or no response (treated as dispute for process).
3) Award if required (Section 10)
If there is no written consent, Section 10 procedures apply and an Award may be made.
Works that commonly fall into the 6 metre category
- basements and lowered floor levels
- deeper engineered foundations (including piles)
- significant ground reduction close to the boundary
- projects where ground conditions require deeper solutions than standard footings
How to explain it simply
“The Act isn’t only about shared walls; it also deals with certain excavations near neighbouring buildings. Because our excavation is deeper, the Act treats it differently even though it is further away.”
What causes disputes in practice
- homeowners assume 6 metres means “not relevant”
- drawings and scope are still changing when notices are served
- the project programme is set before party wall timing is considered
- neighbours receive insufficient explanation and default to dissent for safety
Helpful FAQs
Is anything within 6 metres automatically notifiable?
No. It depends on depth and relationship to neighbouring foundations, but Section 6 is the starting point to assess the position.
What should I do if I’m unsure whether it’s 3 metres or 6 metres?
Treat it as a technical trigger check early. Guessing late usually costs more than checking early.
