Quick answer: for many straightforward London domestic projects, Hourican Associates charge £150 + VAT per adjoining owner for a Party Wall notice service, £385–£585 + VAT for many Schedule of Condition Surveys, and typically £1,100–£1,500 + VAT for a full Party Wall Award service. Basement works, deep excavation and larger or more technical properties are priced separately.
This guide explains how much a Party Wall surveyor costs in London, who usually pays Party Wall surveyor fees, what affects the final fee, and how to keep the process proportionate. It is written for homeowners, architects, developers and adjoining owners dealing with common London projects such as loft conversions, rear extensions, chimney breast removal, boundary wall works, basement works and excavations close to neighbouring properties.

Who pays Party Wall surveyor fees?
In many ordinary domestic projects, the Building Owner carrying out the works pays the reasonable Party Wall surveyor fees because the works are for their benefit. That can include the Building Owner’s surveyor, an impartial Agreed Surveyor, or the adjoining owner’s reasonable surveyor fees if the adjoining owner dissents and appoints a separate Adjoining Owner’s Surveyor.
The word reasonable matters. Party Wall fees should relate to the statutory work needed under the Party Wall etc. Act 1996, not to planning objections, general neighbour disputes, design preferences or unrelated boundary arguments. Costs can be treated differently where works are for repair, where both owners benefit, where an adjoining owner requests additional work, or where unnecessary time is caused by unreasonable behaviour.
| Situation | Who usually pays? | Important note |
|---|---|---|
| Building owner carries out a loft conversion, extension, basement or structural works for their own benefit. | Usually the Building Owner. | This commonly includes reasonable surveyor fees caused by the notifiable works. |
| Adjoining owner dissents and appoints their own surveyor. | Usually the Building Owner pays reasonable adjoining owner surveyor fees. | The fee should be proportionate to the statutory Party Wall work required. |
| Both owners agree to one Agreed Surveyor. | Usually the Building Owner, unless agreed otherwise. | This can reduce duplication, but the Agreed Surveyor must act impartially. |
| The work benefits both properties or is required because of defect or repair. | May be apportioned differently. | Project-specific advice is needed. |
| The adjoining owner asks for extra works for their own benefit. | The adjoining owner may be responsible for those additional costs. | This depends on what is requested and why. |
What are you actually paying a Party Wall surveyor to do?
A Party Wall surveyor’s fee is not simply a charge for producing a document. A properly managed instruction may include reviewing drawings, confirming whether the Party Wall etc. Act 1996 applies, identifying adjoining owners, preparing and serving the correct notice, advising on responses, inspecting the adjoining property, preparing a Schedule of Condition, corresponding with the neighbour or their surveyor, agreeing protective clauses and settling a Party Wall Award.
Typical tasks included in a proper Party Wall process
- Checking whether the proposed works are notifiable under the Party Wall etc. Act 1996.
- Identifying the correct adjoining owners, including freeholders and qualifying long leaseholders where relevant.
- Confirming whether a Party Structure Notice, Line of Junction Notice, Adjacent Excavation Notice or more than one notice type is required.
- Reviewing plans, sections, structural information and foundation details.
- Preparing and serving notices correctly so that the statutory process is not delayed by invalid paperwork.
- Advising on consent, dissent, non-response and agreed surveyor appointments.
- Preparing a written and photographic Schedule of Condition where appropriate.
- Agreeing a Party Wall Award where a dispute arises or a notice is not consented to.
Need a cost for your specific project?
Send your drawings, address and a short summary of the works. We will confirm which notices may be required, whether a Schedule of Condition is sensible, and whether your project is likely to remain notice-only or need a full Party Wall Award.
What affects the cost of a Party Wall surveyor?
Party Wall fees normally increase where the surveyor has to spend more time reviewing technical information, dealing with multiple owners, resolving neighbour concerns, agreeing detailed Award clauses or inspecting larger or higher-risk properties. London projects can be particularly variable because neighbouring structures are often close together and many properties are older, terraced, extended or converted into flats.
Number of adjoining owners
Each affected owner may need to be considered. Flats, leasehold interests and multiple neighbouring properties can increase notice and correspondence work.
Notice type and project scope
A simple notice is very different from a project involving several notice types, excavation, boundary work and structural alterations.
Neighbour response
Written consent can keep matters simpler. Dissent, non-response or a separate adjoining owner’s surveyor will usually require more surveyor time.
Complexity and risk
Basements, underpinning, deep excavation, chimney breast removal and sensitive structures generally need more detailed review.
How much do Party Wall surveyors charge in the UK?
There is no single fixed UK fee for Party Wall surveyors. Costs depend on the location, property type, number of adjoining owners, whether the adjoining owner consents or dissents, and whether the matter needs notices only, a Schedule of Condition or a full Party Wall Award.
London projects are often more variable because properties are closer together, older terraces and converted flats are common, and works may affect several adjoining owners. For London projects, Hourican Associates provide a Party Wall notice service from £150 + VAT per adjoining owner, Schedule of Condition Surveys typically from £385–£585 + VAT, and full Party Wall Award services typically from £1,100–£1,500 + VAT for many domestic matters.
Typical Party Wall cost route by project type
The type of building work often determines how the Party Wall cost route develops. A neighbour who consents to a simple notice may keep costs lower. A neighbour who dissents, or a project that involves structural risk, is more likely to require a Schedule of Condition and Party Wall Award.
| Project type | Common Party Wall issue | Likely cost route |
|---|---|---|
| Loft conversion | Steel beams into a party wall, raising or cutting into a shared wall, mansard or dormer works. | Often starts with a Party Structure Notice. If there is dissent, a Schedule of Condition and Award may be needed. |
| Rear extension | Foundations close to neighbouring structures, building near or on the boundary, flank wall issues. | Notice-only where agreed, or notice plus Schedule of Condition and Award if disputed. |
| Excavation within 3m or 6m | New foundations deeper than neighbouring foundations within the statutory distances. | Adjacent Excavation Notice, drawings and potentially a Schedule of Condition and Award. |
| Chimney breast removal | Cutting away from or altering a party wall or shared structure. | Party Structure Notice and structural information are usually important; an Award may be needed if not consented to. |
| Basement works | Deep excavation, underpinning, temporary works, movement risk and neighbour concern. | Usually quoted separately because the survey, review and Award process is more detailed. |
| Boundary wall or line of junction works | Building a new wall at or near the boundary line. | May require a Line of Junction Notice and careful review of the boundary and proposed wall position. |
Is an Agreed Surveyor cheaper?
An Agreed Surveyor can often be the most proportionate route where both owners are comfortable appointing one impartial surveyor. It avoids duplication between two surveyors and can keep the process calmer, clearer and more cost-effective.
An Agreed Surveyor is not the Building Owner’s surveyor acting for both sides. The surveyor must act impartially under the Act and consider the rights and interests of both owners. If the adjoining owner wants their own surveyor after dissenting, they are entitled to appoint one. Hourican Associates can act as an Agreed Surveyor, Building Owner’s Surveyor or Adjoining Owner’s Surveyor depending on the circumstances.
How much does a Party Wall Agreement cost?
Homeowners often use the phrase “Party Wall Agreement” to describe the paperwork needed before work starts. In practice, where surveyors are appointed following dissent or non-response, the formal document is usually a Party Wall Award. This generally costs more than notice-only support because it can involve surveyor appointments, drawing review, correspondence, inspection, a Schedule of Condition and agreement of protective clauses.
For many domestic London projects, Hourican Associates’ full Party Wall Award service is typically £1,100–£1,500 + VAT. If the adjoining owner consents to a valid notice, the matter may not need an Award, and the cost route may be limited to notice preparation and optional Schedule of Condition work where appropriate.
Building owner or adjoining owner: which cost advice do you need?
I am carrying out the works
Start with our Building Owner’s Surveyor service. We can review your drawings, identify the correct notices, advise on likely fee routes and progress the matter if your neighbour dissents.

Use our Adjoining Owner’s Surveyor service. We can explain whether the notice appears valid, whether consent is appropriate, and whether a Schedule of Condition or Award is advisable.
Ask about a notice receivedHow to keep Party Wall surveyor costs proportionate
The best way to control Party Wall costs is to deal with the process early. Waiting until the builder is ready to start can lead to rushed notices, invalid service, neighbour concern and avoidable delay. A clear, calm and properly served notice can make consent or an Agreed Surveyor appointment more likely.
- Get advice before serving notice. Confirm whether you need a Party Structure Notice, Line of Junction Notice, Adjacent Excavation Notice or a combination.
- Send clear drawings. Plans, sections, structural drawings and foundation details help the surveyor understand the notifiable works.
- Identify all adjoining owners correctly. Serving the wrong person, or missing a qualifying owner, can invalidate the process and cause delay.
- Speak to your neighbour early. A plain-English explanation before formal notice is served can reduce concern.
- Use a Schedule of Condition where sensible. It can reduce later arguments by recording the adjoining property before works begin.
- Avoid relying on cheap notice-only advice for complex works. Basements, deep excavations and structural alterations usually need more detailed review.
Can a free Party Wall notice template reduce costs?
A free template can be useful for understanding the information normally required in a Party Wall notice. Hourican Associates provide a free Party Wall notice template and a free Party Wall acknowledgement template to help owners understand the process.
However, a template cannot confirm whether the Act applies, whether the correct notice type has been selected, whether every adjoining owner has been identified, whether the notice period is right, or whether the drawings are sufficient. For simple works, getting the notice right at the outset can be more cost-effective than trying to fix an invalid notice later.
Does the cheapest Party Wall surveyor save money?
Not always. A low headline fee may exclude checking drawings, confirming owner details, dealing with neighbour questions, inspecting the adjoining property, preparing a Schedule of Condition, negotiating Award clauses or communicating with a separate adjoining owner’s surveyor. The cheapest option can become more expensive if the notice is invalid, the wrong owners are served or the Award requires correction later.
A good Party Wall surveyor should explain what is included, what is excluded, what could increase the fee and whether the matter is suitable for a fixed-fee route. This is especially important for basement works, excavations, older London terraces, converted flats and projects involving several adjoining owners.
