The short answer
A party wall surveyor's fee depends mostly on whether one agreed surveyor acts for both owners or each owner appoints their own. Using a single agreed surveyor on a straightforward residential job, the award commonly costs roughly £700–£1,200+. Where each side appoints a separate surveyor, the building owner pays both, so the total usually rises to around £1,000–£3,000+, and complex cases involving a third surveyor can run higher. Hourly rates typically fall in the £150–£300 per hour region depending on experience and location, with London at the upper end. Extras such as a schedule of condition (often £300–£600 per neighbouring property) and notice preparation can add to the figure. The building owner doing the work normally pays the reasonable fees of both sides.
The single biggest driver is the route: one agreed surveyor is cheaper than two. Location, project complexity and extras like a schedule of condition then move the number. The figures below are typical ranges for guidance, not quotations.
Typical UK fees
- Agreed surveyor (both sides)~£700–£1,200+ award
- Two separate surveyors~£1,000–£3,000+ total
- Hourly rate~£150–£300 / hour
- Schedule of condition~£300–£600 per property
- Who paysusually the building owner
What drives the fee
- One surveyor or two: an agreed surveyor acting for both owners is the lowest-priced route; two separate surveyors roughly doubles the surveying cost because the building owner pays both.
- Complexity: a simple loft or single-storey extension is cheaper than a basement dig affecting several neighbours, which may also bring in a third surveyor.
- Location: London and the South East tend to sit at the upper end of hourly rates and fees.
- Extras: a schedule of condition, multiple notices and any dispute work all add to the total.

Who pays the surveyor's fees
As a general rule, the building owner — the one carrying out the work — pays the reasonable fees of both their own surveyor and the adjoining owner's surveyor, because it is their project that triggers the Act. The award itself sets out who pays what. There are exceptions: where work is partly for the adjoining owner's benefit, or where an owner acts unreasonably, costs can be apportioned differently. The key is that fees must be reasonable, which is one reason an agreed single surveyor keeps the total down.

Frequently asked questions
How much does a party wall surveyor cost?
Using a single agreed surveyor on a straightforward job, the award commonly costs around £700–£1,200+. With two separate surveyors the building owner pays both, so the total usually rises to roughly £1,000–£3,000+. Hourly rates are typically £150–£300, higher in London.
Is one agreed surveyor cheaper than two?
Generally yes. An agreed surveyor acts impartially for both owners, so there is one fee rather than two. Two separate surveyors roughly doubles the surveying cost because the building owner usually pays both sides' reasonable fees.
Who pays the party wall surveyor?
As a rule the building owner doing the work pays the reasonable fees of both surveyors, because it is their project that triggers the Act. The award sets out exactly who pays what, and costs can be apportioned differently in some cases.
