What Happens If My Neighbour Ignores My Party Wall Notice?

Silence is the single most common response to a party wall notice — and it worries building owners more than an outright dissent. The good news: a neighbour cannot stop your works by ignoring you. The Party Wall etc. Act 1996 has a built-in mechanism for exactly this situation.

The 14-day rule

From the day your notice is served, the adjoining owner has 14 days to respond in one of three ways: consent, dissent and appoint their own surveyor, or dissent and agree a single Agreed Surveyor. If 14 days pass with no written reply, Section 5 of the Act deems a dispute to have arisen. That is not a failure — it simply moves the matter onto the surveyor track.

Step by step: what happens next

1. Day 15 — serve a 10-day letter. You write to the adjoining owner requesting that they appoint a surveyor, giving them a further 10 days to do so. This letter is a statutory requirement under Section 10(4), not a courtesy.

2. Day 25 — appoint on their behalf. If they still don't respond, you (through your surveyor) may appoint a surveyor on the adjoining owner's behalf. That surveyor must be independent and cannot be the same person as your surveyor. The neighbour loses the right to choose who represents them — the only real consequence of ignoring the notice.

3. The two surveyors select a Third Surveyor. A tiebreaker who is only called on if the two appointed surveyors disagree. In practice this almost never happens.

4. Schedule of Condition and Award. The surveyors inspect the adjoining property, record its condition photographically, and draft the Party Wall Award setting out permitted works, working hours, protective measures and the damage-resolution process.

5. Award served — you can start. Once served, your works are lawful. Either owner has 14 days to appeal to the county court on a point of law; appeals are very rare.

How long does the whole thing take?

Realistically 4 to 8 weeks from the day the notice is served to the day the Award lands — and most of that is statutory waiting time, not surveyor work. Because that runs in parallel with the two-month (Section 2) or one-month (Section 6) notice period, a silent neighbour usually costs you no extra time at all if you served your notice early.

What it costs

• First notice: £50, each additional notice £30
• Party Wall Award where a neighbour dissents or stays silent: £850
• Where both owners agree a single Agreed Surveyor instead: £650 — the cheapest route, and it includes the Schedule of Condition

The building owner pays the reasonable fees of both surveyors. If you're on the receiving end of a notice, your cost is £0 — see [who pays for a party wall surveyor](/blog/who-pays-for-a-party-wall-surveyor).

Four mistakes to avoid when a neighbour goes quiet

• Starting work anyway. Without an Award you're exposed to an injunction and a damages claim, whatever your builder tells you.
• Re-serving the notice. It's already valid. Re-serving resets nothing and wastes two weeks.
• Skipping the 10-day letter. Appointing on their behalf without it makes the appointment — and the Award — challengeable.
• Chasing informally and doing nothing else. A friendly text is fine, but the statutory clock only advances on properly served written documents.

Common reasons neighbours don't reply

Most silence isn't hostility. Notices go to a landlord rather than the tenant living there, land at a second home, get mistaken for junk mail, or simply intimidate someone who doesn't understand the document. A short, plain-English covering letter alongside the formal notice measurably increases the consent rate — and a consent keeps your total at £50.

Where we can help

We draft and serve Act-compliant notices, track the 14-day window for you, issue the 10-day letter automatically if there's no reply, and appoint on the adjoining owner's behalf where the Act allows — all on published fixed fees.
