The short answer
If a neighbour does not reply to a valid party wall notice within 14 days, the Party Wall etc. Act 1996 treats this as dissent, so a dispute is deemed to have arisen. That does not stop your project: it moves it onto the surveyor route. The building owner then serves a further '10-day notice' asking the neighbour to appoint a surveyor; if the neighbour still does nothing within those 10 days, the building owner can appoint a surveyor on the neighbour's behalf so an award can be produced. The whole mechanism exists so that silence cannot block the work indefinitely — but it also protects the neighbour, because an independent surveyor still sets fair terms and records the property's condition. This is general guidance, not legal advice.
A non-response feels like a problem but is actually a defined path in the Act. Here is what happens step by step, and why a neighbour ignoring the notice does not give them a veto.

The step-by-step path when there's no reply
- 14 days pass with no response: the neighbour is deemed to have dissented, so a dispute has arisen under the Act.
- Serve a 10-day notice: the building owner writes to the neighbour requiring them to appoint a surveyor within ten days.
- Still no action: if the neighbour does not appoint within those 10 days, the building owner may appoint a surveyor on the neighbour's behalf.
- Award produced: the surveyor(s) draw up the party wall award that governs how, when and on what terms the work proceeds.

Why ignoring it is not a veto
The Act is deliberately built so a neighbour cannot stall your project by staying silent. A non-response simply triggers the surveyor route, and the surveyor then sets the terms an award would set anyway. It is, however, in both owners' interests to engage: the surveyor will record a schedule of condition protecting the neighbour against unfair damage claims, and an agreed approach is usually cheaper and quicker than a drawn-out one. The building owner generally pays the reasonable surveyor fees, so a co-operative neighbour is not out of pocket for following the process.
Neighbour not responding to your notice?
We'll match you with a vetted party wall surveyor who handles the deemed-dispute path correctly — the 10-day notice and appointment — so your project can proceed on fair terms.
Frequently asked questions
What happens if my neighbour ignores my party wall notice?
If they do not reply within 14 days, the Act treats it as dissent and a dispute is deemed to have arisen. You then serve a 10-day notice asking them to appoint a surveyor; if they still do nothing, you can appoint one on their behalf so an award can be produced and the work can proceed.
Can a neighbour block my building work by ignoring the notice?
No. Silence is not a veto. It triggers the surveyor route under the Act, and an independent surveyor sets fair terms in an award so the work can go ahead. The process protects the neighbour while preventing indefinite delay.
What is a 10-day notice in party wall disputes?
It is the further written notice a building owner serves once a dispute is deemed to have arisen, requiring the neighbour to appoint a surveyor within ten days. If they do not, the building owner can appoint a surveyor on their behalf.
