A Schedule of Condition Survey in London records the condition of a neighbouring property before building works begin. It is one of the most practical ways to protect both Building Owners and Adjoining Owners during party wall works, loft conversions, rear extensions, excavations and basement projects.

View Schedule of Condition service Request a quoteIf you are planning building works in London — such as a loft conversion, rear extension, chimney breast removal, excavation close to neighbouring foundations or basement works — it is sensible to record the condition of any adjoining property before work starts.
A well-prepared Schedule of Condition gives the Building Owner and Adjoining Owner a clear, dated written and photographic record of any existing cracks, defects, movement, damp staining or damage. If a neighbour later believes damage has been caused by the works, the report provides an independent baseline to compare against.
What is a Schedule of Condition?
A Schedule of Condition is a detailed written and photographic record of a property’s condition at a specific point in time, usually before nearby construction works begin. It records visible defects such as cracks, staining, uneven floors, damaged plaster, external brickwork issues, boundary wall defects and other relevant features.
In party wall matters, the Schedule of Condition is commonly attached to, or referred to within, a Party Wall Award. This helps create an agreed baseline before notifiable works start.
If damage is alleged later, the surveyors can compare the post-works condition with the original report to assess whether the defect was pre-existing or may have been caused by the works.
What is a Schedule of Condition Survey?
A Schedule of Condition Survey is the inspection carried out by a qualified surveyor to prepare the report. The surveyor visits the relevant property, records the condition of internal and external areas, takes photographs and prepares a formal document that can be relied upon if a damage dispute arises.
These surveys are particularly valuable in London, where terraced houses, semi-detached properties, mansion blocks, flats and tightly packed developments often mean construction work takes place close to neighbouring buildings, shared walls and boundaries.
Legal Context: Party Wall etc. Act 1996
A Schedule of Condition is not always a strict legal requirement, but it is strongly recommended where works fall under the Party Wall etc. Act 1996. The Act provides a framework for preventing and resolving disputes involving party walls, party structures, boundary walls and excavations near neighbouring buildings.
The Building Owner may be responsible for making good or compensating damage caused by notifiable works. A clear pre-works condition record therefore helps both sides understand what was already present before works began.
In practice, most properly handled Party Wall Awards in London include or refer to a Schedule of Condition, especially where works involve structural alterations, roof works, extensions, excavations, basements or changes to party walls.
Why a Schedule of Condition Matters
Construction can create concern for neighbours, particularly where works are close to shared walls, boundary walls, chimney breasts or foundations. A Schedule of Condition helps keep the process transparent and neighbourly by creating an independent record before any work begins.
- Protects the Building Owner against unfounded or exaggerated damage claims.
- Protects the Adjoining Owner by recording the condition of their property before works start.
- Supports the Party Wall Award with clear, evidence-based documentation.
- Reduces disputes by showing whether cracks, staining or defects existed before the works.
- Provides peace of mind for both neighbours during the construction process.
When Should You Arrange a Schedule of Condition Survey?
Schedule of Condition Surveys are commonly recommended before:
- Loft conversions, dormers and mansard roof extensions
- Chimney breast removals and structural steel installations
- Basement excavations, underpinning and lower ground floor works
- Rear extensions, side returns and ground floor extensions
- Excavations within 3 or 6 metres of neighbouring foundations
- Works affecting shared walls, party structures, boundary walls or adjoining buildings
Ideally, the survey should be carried out after the relevant Party Wall Notice has been served and before contractors, demolition works, excavation or machinery start on site.
Schedule of Condition Survey vs Party Wall Award
A Schedule of Condition and a Party Wall Award are often connected, but they are not the same thing.
| Item | Purpose | When it is used |
|---|---|---|
| Schedule of Condition | Records the existing condition of the adjoining property in writing and photographs. | Before works begin, especially where damage could later be alleged. |
| Party Wall Award | Sets out how notifiable works should proceed under the Party Wall etc. Act 1996. | Where a dispute has arisen or an Adjoining Owner dissents to a Party Wall Notice. |
For many projects, the Schedule of Condition is appended to the Party Wall Award so that the agreed condition record forms part of the wider party wall documentation.
What’s Included in the Report?
A professionally prepared Schedule of Condition report will usually include:
- Time-stamped photographs of relevant internal and external areas
- Written descriptions of existing cracks, defects, damp staining, movement or deterioration
- Notes on walls, ceilings, floors, windows, doors, boundary walls and external elevations
- Photographic references or annotations to identify each defect clearly
- A formal digital PDF report suitable for inclusion with a Party Wall Award
- Hard copy report available on request
Where the works are more complex, such as basement excavations or extensive structural alterations, the survey may need to cover a wider area of the adjoining property.
Cost of a Schedule of Condition Survey in London
Our Schedule of Condition Survey fees usually range from £385–£585 + VAT, depending on the nature of the works, size of the property, access requirements and the level of detail required.
This typically includes:
- Site visit by a qualified surveyor
- Written and photographic condition report
- Digital PDF report
- Hard copy available on request
- Fast turnaround, usually within 2–3 working days where access is straightforward
Basement surveys are priced separately because they often require a more detailed inspection of the whole property, including lower ground floor areas, structural elements, party walls and external areas.

Go to Schedule of Condition serviceWho Pays for the Schedule of Condition?
In most party wall matters, the Building Owner pays the reasonable costs of the Party Wall process, including the Schedule of Condition Survey. This is because the Building Owner is the party carrying out the works.
The Adjoining Owner does not usually pay for the Schedule of Condition where it forms part of the Party Wall process. If a standalone survey is requested outside a formal party wall procedure, the position should be agreed clearly before the survey is booked.
For more guidance on each party’s role, see our pages for Building Owners and Adjoining Owners.
Do You Need One if Your Neighbour Has Consented?
Yes, it can still be sensible. If an Adjoining Owner consents to a Party Wall Notice, a formal Party Wall Award may not be required. However, consent does not remove the risk of later disagreement if damage is alleged.
A standalone Schedule of Condition can be a cost-effective way to keep matters clear and neighbourly, particularly for loft conversions, rear extensions, chimney removals and excavation works.
Schedule of Condition Surveys for Building Owners
If you are the Building Owner carrying out the works, a Schedule of Condition helps protect you from claims that existing cracks, staining or historic defects were caused by your project. It also shows your neighbour that you are approaching the works responsibly.
Hourican Associates can prepare the survey as part of a wider party wall service, including Party Wall Notices, Party Wall Awards and project-specific party wall advice.
Schedule of Condition Surveys for Adjoining Owners
If your neighbour is carrying out works near your home, a Schedule of Condition helps protect your position by recording the condition of your property before works begin. This can be particularly important if the works involve excavation, roof alterations, party wall works or structural changes close to your property.
If you have received a notice and are unsure what to do next, read our Adjoining Owner Surveyor Services page or contact us for practical advice.
