If you’re planning construction work that affects a shared wall with your neighbour, understanding who pays for a party wall surveyor is crucial. This guide explains the legal responsibilities, payment obligations, and potential disputes that may arise. We’ll cover everything UK homeowners need to know about party wall surveyor costs, from basic principles to complex scenarios, helping you navigate this often confusing aspect of property renovation.
What is a Party Wall and When Do You Need a Surveyor?
A party wall is a structure that stands on the boundary between two properties and is shared by both owners. This includes walls between semi-detached or terraced houses, garden walls built across a boundary, and walls where one building is supported by another’s wall. The Party Wall etc. Act 1996 governs work affecting these structures.
You’ll need a party wall surveyor when:
- Building a new wall on or at the boundary
- Working on an existing party wall (e.g., cutting into it, rebuilding it)
- Excavating near a neighbouring building
- Carrying out loft conversions or extensions that affect party walls
- Installing damp proof courses that affect party structures
A party wall surveyor’s role is to prepare a Party Wall Award (also called a Party Wall Agreement), which outlines how work will proceed, working hours, access arrangements, and a schedule of condition of the adjoining property.

Who Pays for the Party Wall Surveyor?
The fundamental principle under the Party Wall etc. Act 1996 is that the building owner (the person initiating the construction work) is responsible for paying all reasonable costs associated with the party wall process. This includes:
Building Owner Pays For:
- Their own party wall surveyor’s fees
- The adjoining owner’s surveyor’s fees
- Costs of preparing the Party Wall Award
- Any necessary Schedule of Condition
- Reasonable administration costs
Adjoining Owner Typically Pays:
- Nothing for standard party wall procedures
- Only costs for additional work they specifically request
- Their own surveyor if they reject an “agreed surveyor”
- Costs related to unreasonable behavior during disputes
The building owner who initiates construction work affecting a party wall is generally responsible for all reasonable surveyor costs, including those of the adjoining owner.
Common Payment Scenarios Explained
Scenario 1: Standard Construction Work
When you’re planning a loft conversion, extension, or other work affecting a party wall, you (as the building owner) will typically pay all surveyor costs. This applies even if your neighbour (the adjoining owner) appoints their own surveyor rather than using an “agreed surveyor” who acts for both parties.
Scenario 2: Repair Work to a Defective Party Wall
If work is needed to repair a defective party wall, costs may be shared between both property owners. The Party Wall Act allows for costs to be apportioned according to:
- The use each owner makes of the structure
- Responsibility for the defect or need for repair
- Benefit each owner derives from the work
Scenario 3: Additional Work Requested by Adjoining Owner
If your neighbour requests additional work beyond what’s necessary for your project, they should pay for those extra costs. This is known as a “counter notice” under the Act, where they can request additional work be done at the same time (at their expense).
Key Takeaways: Who Pays for Party Wall Surveyors
- Building owner (person doing the work) typically pays all surveyor costs
- Adjoining owner (neighbour) usually pays nothing unless they request additional work
- Repair costs to defective party walls may be shared between owners
- The Act aims to protect adjoining owners from financial burden for work they didn’t initiate
- Costs can be reallocated if either party behaves unreasonably
Party Wall Surveyor Costs: What to Expect
Understanding the potential costs involved helps you budget appropriately for your construction project. Party wall surveyor fees vary based on several factors:
Typical Fee Structures:
- Hourly rates: £90-£450 per hour
- Fixed fees: £900-£1,500 for straightforward projects
- Complex projects: £2,000-£6,000 for basement works
Factors Affecting Costs:
- Property location (London typically more expensive)
- Project complexity and scale
- Number of adjoining owners
- Number of surveyors involved
- Time required for inspections and documentation
| Project Type | Average Cost Range | Typical Timeframe | Number of Surveyors |
| Loft Conversion | £900-£1,500 | 4-6 weeks | 1-2 |

Single Surveyor vs. Two Surveyors: Cost Implications
The number of surveyors involved significantly impacts the overall cost of the party wall process. There are two main approaches:
Agreed Surveyor Approach
Both the building owner and adjoining owner agree to use one impartial surveyor who acts for both parties. This is the most cost-effective option.
- Lower overall costs (typically £900-£1,500)
- Streamlined communication
- Faster resolution
- Building owner pays all fees
Two Surveyors Approach
Each owner appoints their own surveyor, who then select a third “agreed surveyor” to resolve any disputes between them.
- Higher costs (typically £1,800-£3,000+)
- More complex communication
- Longer timeframes
- Building owner still pays all fees
Even when two surveyors are involved, the building owner typically pays for both. This can double your costs, making it financially beneficial to encourage your neighbour to agree to a single “agreed surveyor.”
Dispute Resolution and Cost Allocation
Disputes can arise during the party wall process, potentially affecting who pays for what. Understanding how these are resolved is important for all parties involved.
Common Disputes Over Surveyor Fees
- Building owner believing fees are excessive
- Disagreements over the necessity of certain work
- Disputes over damage caused during construction
- Adjoining owner making unreasonable demands
The Third Surveyor’s Role
When two surveyors are appointed, they select a third surveyor who can be called upon to resolve disputes. This third surveyor can make determinations about:
- Whether surveyor fees are reasonable
- Who should pay for specific costs
- Reallocation of costs due to unreasonable behavior
- Disputes about the content of the Party Wall Award
Cost Reallocation in Disputes
The Party Wall etc. Act 1996 allows for costs to be reallocated if either party behaves unreasonably. For example, if an adjoining owner raises spurious objections or a building owner fails to follow proper procedures, the third surveyor may order the unreasonable party to pay some or all of the costs.
How to Reduce Party Wall Surveyor Costs
While the building owner typically bears the costs, there are several strategies to keep party wall surveyor expenses manageable:
Communicate Early
Speak with your neighbours before serving formal notices. Good communication can encourage them to agree to a single surveyor approach, potentially halving your costs.
Provide Clear Plans
Ensure your architectural plans are detailed and complete. Vague or incomplete plans increase the time surveyors spend interpreting your proposals, driving up hourly costs.
Offer a Schedule of Condition
Proactively offer to pay for a Schedule of Condition of your neighbour’s property. This builds trust and may encourage them to consent to the work without appointing their own surveyor.
Investing time in neighbour relations before formal notices are served can save thousands of pounds in surveyor fees and prevent costly disputes.

Frequently Asked Questions About Party Wall Surveyor Costs
Can my neighbour refuse to pay for their own party wall surveyor?
Your neighbour (the adjoining owner) doesn’t have to pay for their own party wall surveyor. Under the Party Wall etc. Act 1996, you as the building owner are responsible for paying all reasonable surveyor costs, including those of your neighbour’s surveyor if they choose to appoint one. The only exception is if your neighbour requests additional work beyond what’s necessary for your project, in which case they would pay for those specific extra costs.
What happens if multiple surveyors are involved?
If multiple surveyors are involved, costs will increase significantly. When each owner appoints their own surveyor, these two surveyors select a third “agreed surveyor” who can be called upon to resolve disputes. Even with multiple surveyors, the building owner typically pays all reasonable costs. If the two appointed surveyors cannot agree, the third surveyor makes a determination, which may include decisions about cost allocation. This three-surveyor approach can double or triple the overall expense compared to using a single agreed surveyor.
How are party wall surveyor costs calculated?
Party wall surveyor costs are typically calculated using one of these methods:
- Hourly rates: Most surveyors charge by the hour, with rates ranging from £90 to £450 depending on experience and location.
- Fixed fees: Some surveyors offer fixed fees for straightforward projects, typically between £900 and £1,500.
- Percentage-based fees: Occasionally, fees may be calculated as a percentage of the construction costs, though this is less common for party wall work.
Factors affecting the final cost include property size, project complexity, number of adjoining owners, time spent on site visits, and documentation preparation. London-based surveyors typically charge higher rates than those in other parts of the UK.
Can I recover party wall surveyor costs if my neighbour is being unreasonable?
Yes, in certain circumstances. If your neighbour (the adjoining owner) behaves unreasonably during the party wall process, you may be able to recover some costs. The third surveyor can make determinations about cost allocation if either party is deemed to be acting unreasonably. Examples of unreasonable behavior might include:
- Making spurious objections to delay the process
- Refusing access for necessary inspections
- Making excessive or unnecessary demands
- Failing to respond to communications within reasonable timeframes
However, proving unreasonable behavior can be difficult, and it’s generally better to maintain good relations with your neighbour if possible.
Do I need to pay for a party wall surveyor if my neighbour consents to the work?
If your neighbour gives written consent to your party wall notice within 14 days, you don’t legally need to appoint a party wall surveyor or create a formal Party Wall Award. This can save significant costs. However, even with consent, it’s often advisable to:
- Create a Schedule of Condition of your neighbour’s property before work begins
- Have a simple agreement in writing about how the work will proceed
- Ensure your contractor has appropriate insurance
These precautions can help prevent disputes later if damage occurs, potentially saving money in the long run despite the initial expense.
