How to choose a party wall surveyor
Last updated: 16 August 2026
Start with the fact nobody in the industry leads with: the Party Wall Act sets no qualification requirement whatsoever. A "surveyor" under the Act is simply a person who isn't a party to the matter. No exam, no register, no chartered status, no minimum experience. The law is not filtering these people for you — which is precisely why how you choose matters.
Is the role regulated? Not by the Act
Section 20 of the Act defines a surveyor as any person who is not a party to the matter. That's the whole test. It means two things at once, and they pull in opposite directions:
- You cannot act for yourself. Neither owner can take the role, however capable they are — you're a party to the matter. (Serving your own notice is different, and completely allowed.)
- Almost anyone else can. The Act imposes no membership of RICS, the Faculty of Party Wall Surveyors, Pyramus & Thisbe, or anything else. Those bodies matter — they run directories, set conduct standards and give you somewhere to complain — but that's their doing, not the Act's.
So the professional bodies are doing work the statute doesn't. That's a reason to prefer a member, not a reason to assume the law demands one.
What actually separates a good appointment
Since the statutory bar is nil, the useful questions are practical ones. In rough order of how much they predict:
| Ask | Why it tells you something |
|---|---|
| "How much of your work is party wall matters?" | Plenty of general surveyors take the odd one. The Act has a lot of procedural traps, and a defective notice or a mishandled appointment costs far more than the fee saved. |
| "Which body are you a member of, and can I check?" | Not required by the Act — which is exactly why it's informative. It also gives you a complaints route that otherwise doesn't exist. |
| "What's included, and what's extra?" | Get the schedule of condition, the award, and any site visits itemised. Fee disputes almost always start as scope misunderstandings. |
| "Who will actually do the work?" | The person quoting isn't always the person attending. Fine if you know; annoying if you don't. |
| "How quickly do you respond, and what's your capacity right now?" | The commonest complaint by a distance is not competence — it's silence. |
One surveyor or two?
There are two routes once a dispute exists. A single agreed surveyor acts impartially for both owners — usually faster and cheaper. Or each owner appoints their own, and those two select a third surveyor at the outset as a tiebreak.
The trade-off is rarely explained honestly. The agreed-surveyor route saves money — mostly the building owner's money, since they normally carry the fees — and it is genuinely binding on both of you. What it removes is the escalation route: with one agreed surveyor, there is no third surveyor to appeal to. Cheaper, and one fewer safety valve. Who pays for a party wall surveyor covers the money side properly.
Can I just use my neighbour's surveyor?
You can agree to a single surveyor, and it's often sensible. But be clear about what you're agreeing to: an agreed surveyor is impartial, not yours. If the works are substantial, or the relationship is already strained, having your own is a real protection — and in the standard case your neighbour normally carries the reasonable cost of it anyway.
If your neighbour won't engage
This is the situation that stalls most projects, and the Act has a specific answer. If one side refuses or neglects to appoint a surveyor, the other can make a written request and, after ten days, appoint a surveyor on their behalf. Silence doesn't stop the process — it just hands the choice to someone else.
Worth knowing from the other direction too: if you're the neighbour and you ignore this, a surveyor gets appointed for you by the person doing the building work. Engaging is almost always the better move.
If you're unhappy with the surveyor you've got
Here's the constraint people find out too late: an appointment can't be rescinded by the party who made it. You cannot simply replace a surveyor for being slow or unhelpful. That's why the choosing matters, and it's why "appoint someone today so it looks like I'm responding" is a bad instinct.
What you can do:
- Raise it in writing, with both surveyors, and be specific about what's outstanding.
- Use the third surveyor. On the two-surveyor route, either owner or either surveyor can refer a matter to the third — acting alone. You don't need your neighbour's agreement, and you don't need your own surveyor's blessing. That route is genuinely yours to use.
- Complain to their professional body, if they belong to one. This is the practical reason membership is worth asking about at the start.
- Appeal the award to the county court within 14 days of it being served on you, if the problem is the award itself rather than the service. That's a short clock — see the party wall award.
Do you need one at all?
Often, no. A surveyor becomes necessary when a dispute exists — which happens when your neighbour dissents, or simply doesn't reply to a section 2 or section 6 notice within 14 days. If they consent in writing, no surveyor is appointed and the process ends there.
And serving the notice itself needs nobody. You can do it yourself for free using the government's example letters. Firms charge roughly £65–£150 plus VAT per neighbour to draft and serve, which is a reasonable convenience but not a legal necessity — and it buys you nothing extra if the notice is straightforward.
