Quick answer: The building owner proposing the work normally pays the reasonable costs of the statutory Party Wall process, including the adjoining owner’s surveyor where separate appointments are justified. This is not an unlimited entitlement: fees must relate to the work and be reasonable.
This article concerns England and Wales. It provides general information, not legal advice. The application of the Party Wall etc. Act 1996 depends on the facts, ownership and proposed work.
What costs may be included
Reasonable costs can include reviewing notices and drawings, inspecting the properties, preparing a schedule of condition, agreeing an award and dealing with relevant design revisions.
What makes a fee reasonable
Complexity, risk, travel, the number of owners, quality of drawings, design changes and time genuinely spent can affect the fee. Poor information and late changes often increase costs.
When might the adjoining owner pay?
An adjoining owner may be responsible for costs generated solely by optional works requested for their benefit or by unreasonable conduct. Responsibility depends on the facts and any agreement or award.
How to control costs
Provide complete drawings early, consider an agreed surveyor where suitable, request clear fee proposals and avoid using the statutory process to pursue unrelated boundary or planning disputes.
Frequently asked questions
Is there a fixed statutory fee?
No. The Act does not set a universal fixed price.
Must the building owner accept any invoice?
No. Only reasonable costs properly connected with the statutory function should be payable; disputes may require specialist advice.
