How much does a party wall surveyor cost?
Party wall costs range from a simple notice to a full surveyor-negotiated award. Estimate a typical case below.
When the Party Wall Act applies
- 1Notifiable work
Work to a shared wall, excavation near a neighbour's foundations, or building on the boundary triggers the Party Wall Act.
- 2Notice and consent
You serve notice; if the neighbour consents in writing, you may avoid surveyor fees entirely.
- 3The award
If they dissent, surveyor(s) agree an award and a schedule of condition — with fees typically paid by you.
Party wall matters catch out first-time developers on terraces and semis, where almost any structural or extension work is notifiable. Serve notice early — it has statutory timescales — and budget a fee per adjoining owner so it doesn't stall the programme.
Party wall costs (indicative)
| Scenario | Basis | Indicative cost |
|---|---|---|
| Notice + consent (no award) | low | £0 – £300 |
| Agreed surveyor (one) | per matter | £700 – £1,400 |
| Two surveyors (per neighbour) | each side | £1,500 – £2,500+ |
| Schedule of condition | included | usually |
The building owner usually pays the reasonable surveyor fees. More adjoining owners means more matters.
