1. The basic rule: the building owner pays
The fundamental principle under the Party Wall Act is straightforward: the building owner (the person doing the work) pays the reasonable costs of the party wall process.
This includes:
- The building owner’s own surveyor’s fees
- The adjoining owner’s surveyor’s fees
- Any agreed surveyor’s fees (if one surveyor acts for both)
- The third surveyor’s fees (if one is appointed to resolve disputes)
The adjoining owner — the neighbour affected by the proposed work — generally pays nothing for the party wall process.
This makes sense. The building owner is the one who wants to do the work and triggers the statutory process. The adjoining owner didn’t ask for any of this. The Act protects adjoining owners by ensuring they get professional representation without having to pay for it.
2. Why adjoining owners get free representation
The Party Wall Act creates a framework where:
- Building owners can proceed with legitimate work affecting boundaries
- Adjoining owners are protected from damage and disruption
- Disputes are resolved through surveyors rather than courts
For this to work fairly, adjoining owners need access to professional advice. If they had to pay their own surveyor, many would decline representation and proceed unprotected — or the process would become adversarial.
By making the building owner pay, the Act ensures:
- Adjoining owners can get proper representation
- There’s no financial barrier to protection
- The costs are borne by the party benefiting from the work
3. What the adjoining owner’s surveyor does
If you’re an adjoining owner who has appointed your own surveyor (rather than agreeing to an agreed surveyor), your surveyor will:
Protect your interests — Review the proposed works, ensure adequate protection, and represent your position in the award process.
Prepare the Schedule of Condition — Document your property’s condition before work starts, creating evidence if damage occurs.
Negotiate the award — Work with the building owner’s surveyor to agree award terms that properly protect you.
Monitor if needed — In some cases, inspect during works to check compliance.
Address damage — If damage occurs, pursue your rights through the award mechanism.
All of this is at the building owner’s expense.
4. What counts as “reasonable costs”
The building owner pays reasonable costs. This doesn’t mean unlimited costs or gold-plated fees.
Reasonable costs typically reflect:
- The complexity of the proposed works
- The extent of potential impact on the adjoining owner
- Standard market rates for party wall work
- Time actually spent (not inflated estimates)
If a surveyor’s fees seem unreasonable, the building owner (or their surveyor) can challenge them. Ultimately, if the surveyors can’t agree on costs, the third surveyor can determine what’s reasonable.
In practice, most party wall surveyor fees are modest — a few hundred to a couple of thousand pounds for straightforward cases, more for complex situations.
5. Scenarios and who pays what
Scenario 1: Agreed surveyor
You and your neighbour agree to appoint one surveyor to act for both of you.
- Who pays: Building owner pays the agreed surveyor’s fees
- Cost: Lower than two surveyors (one fee instead of two)
- Trade-off: Adjoining owner doesn’t have independent representation
Scenario 2: Two surveyors
Each party appoints their own surveyor.
- Who pays: Building owner pays both surveyors’ fees
- Cost: Higher than agreed surveyor
- Benefit: Adjoining owner has independent representation
Scenario 3: Third surveyor involvement
The two surveyors can’t agree on something and refer to a third surveyor.
- Who pays: Building owner (usually, though the third surveyor can apportion costs if one party has been unreasonable)
- Cost: Additional fees on top of the two surveyors
- Situation: Relatively rare — most matters resolve between two surveyors
Scenario 4: Adjoining owner doesn’t respond
The adjoining owner doesn’t respond to the notice within 14 days (deemed dissent) and doesn’t appoint a surveyor within 10 days.
- What happens: Building owner can appoint a surveyor to act for the adjoining owner
- Who pays: Building owner pays both surveyors’ fees
6. For building owners: budgeting for party wall costs
If you’re planning work that triggers the Party Wall Act, budget for:
Your surveyor — To prepare and serve notices, manage the process, and prepare the award.
Your neighbour’s surveyor — If they appoint their own (which is their right).
Schedule of Condition — Documenting your neighbour’s property.
Potentially multiple neighbours — If your work affects several adjoining owners, you’re paying for each.
7. For adjoining owners: what you don’t pay
As an adjoining owner, you don’t pay for:
- Your surveyor’s fees
- The Schedule of Condition
- The award preparation
- Inspections during works
You may choose to pay for additional services beyond the statutory process — for example, more frequent monitoring than the award requires, or advice on matters outside the Act — but the basic party wall process is at the building owner’s expense.
8. Costs vs value
For building owners, party wall costs sometimes feel like an unwelcome burden. But consider what you’re getting:
Legal compliance — Without proper notices and awards, you’re building illegally and exposed to injunction.
Protection — The Schedule of Condition protects you against false damage claims.
Certainty — The award sets out rights and responsibilities clearly.
Dispute resolution — If problems arise, there’s a mechanism to resolve them.
The cost of the party wall process is typically small relative to building project costs — and trivial compared to the cost of disputes, injunctions, or litigation that can arise without it.
Key Takeaways
- Building owner pays — for both their own and the adjoining owner’s surveyor
- Adjoining owners pay nothing — for standard party wall representation
- Costs must be reasonable — but can be challenged if excessive
- Agreed surveyor is cheaper — but adjoining owner loses independent representation
- Budget appropriately — party wall costs are part of your project costs
- It’s worth it — proper process prevents much more expensive problems
