Who Pays the Bill? Party Wall Costs Explained for Homeowners
The Party Wall etc. Act 1996 in the UK governs the rights and responsibilities of property owners sharing a boundary or party wall when undertaking construction work.
A critical practical aspect for clients considering works under this Act is the cost involved in appointing Party Wall Surveyors and the associated award preparation, which helps avoid disputes and provides legal protection.
Understanding Party Wall Surveyor Costs
Party Wall Surveyors are appointed to administer the Party Wall Act, which involves serving notices, preparing agreements (Party Wall Awards), and resolving disputes centred on shared structures or boundaries. Costs to clients depend primarily on the surveyor arrangement, the complexity of the project, and geographic location.
Surveyor Fee Structures
Hourly Rates: Most surveyors charge hourly rates ranging broadly from about £90 to £450 per hour, with typical averages between £150 and £200 per hour. Higher rates are common in London and the Southeast where living and professional expenses are elevated.
Flat Fees: For straightforward projects, surveyors may offer flat fees, usually ranging between £700 and £1,500 per neighbour. This can simplify budgeting for homeowners.
Single Agreed Surveyor vs Two Surveyors (One per Party)
Three main appointment types affect costs:
Surveyor Arrangement | Typical Cost Range | Notes |
Agreed Surveyor (one surveyor shared by both parties) | £600 to £2,000 total | This surveyor acts impartially for both parties; cost is shared, usually split evenly. Focuses on efficiency and cost saving. More common for straightforward or uncontested projects |
Two Surveyors (one appointed by each party) | £2,000 to £4,000 combined total | Each surveyor represents one party; costs double but may be necessary in complex or contested matters. Building owner generally pays both surveyors' fees under the Act |
Single Surveyor - Sole Representation | £700 to £2,000 per client | Surveyor acting solely for one party, typically the party carrying out the work. The other party may appoint their own surveyor with additional costs. |
Drafting and Serving One Notice | £40 – £150 | Price varies by provider, service level, and location. Includes basic legal notice and explanatory letter. |
Serving Multiple Notices | £40 – £150 each | Cost per neighbour; multiply by number of adjoining properties. |
London-Specific Notice Service | £80 – £150 per notice | Generally higher due to market rates.

Average Costs of Party Wall Awards
Party Wall Awards are formal written agreements that detail the rights and obligations concerning the construction works and are legally binding once signed. Costs depend on the complexity of the project and conditions involved:
Simple cases (e.g., minor wall adjustments or small loft conversions): Awards and surveyor fees typically total around £1,000 per party, or as low as £700 where a single agreed surveyor is appointed.
More complex projects (e.g., basement excavations, substantial structural work, or multiple adjoining owners): Costs can increase significantly, and combined fees for two surveyors and awards may rise to £4,000 or more. Exceptional cases, like extensive foundations excavation, can push fees even higher, potentially beyond £6,000
Who Pays for What?
Under the Party Wall etc. Act 1996, the building owner requesting the work is generally responsible for all costs associated with the surveyors and the preparation of the award. This includes any fees for the adjoining owners’ surveyors if two surveyors are appointed. This legal requirement ensures neighbours are not financially disadvantaged by others’ construction work .
Factors Influencing Costs
Project complexity: More complex or contentious works require more extensive inspections, reports, and negotiations.
Location: Surveyors in London and the South East tend to charge more than those in other parts of the UK.
Number of surveyors involved: Agreed surveyors centralise costs; separate surveyors can double fees.
Type of construction: Basement excavations or large extensions usually cost more due to higher risk and technical detail.
Legal incidental costs: Additional costs may arise if specialist engineers or legal licenses (e.g., Build over Agreements in London) are needed within the process
Managing and Minimising Costs
Clients can keep costs manageable by:
Appointing a single agreed surveyor where possible to halve fees.
Choosing experienced local surveyors for more predictable charges.
Providing clear, full initial project details to avoid costly delays or misunderstandings.
Considering surveyor fee structures (fixed fees versus hourly) based on project certainty.
Avoiding contentious disputes through good neighbourly communication to prevent the need for two surveyors.
In summary, clients should anticipate Party Wall Surveyor costs generally between £700 and £2,000 for an agreed surveyor handling typical projects, rising to £2,000 to £4,000 or more when two surveyors are involved. The building owner covers these costs under the Party Wall Act. Awards themselves are usually integrated into these fees, with complexity and location playing a major role in overall expenses. Proper budgeting and understanding of the Party Wall process help avoid surprises during construction projects affecting shared boundaries.
