What Does a Level 3 Building Survey Include?
A level 3 building survey provides a detailed assessment of a property's condition, construction and visible defects. It is designed for buyers who need more information than a standard visual inspection can provide. This can be especially useful when purchasing an older, unusual, altered or poorly maintained property.
The survey can help you understand the condition of the building before you commit to a purchase. It can also highlight areas that may need further investigation, repair or ongoing maintenance.
For buyers considering an older home or a property with visible defects, understanding what a level 3 building survey includes can make it easier to choose the right professional service.
What Is a Level 3 Building Survey?
A level 3 building survey is the most comprehensive of the standard RICS Home Survey options. RICS describes it as a detailed inspection and report intended to provide professional advice about the property's condition, defects, potential risks and repair needs.
It was previously known as an RICS Building Survey. The current RICS naming system uses RICS Home Survey Level 3.
Unlike a basic survey, the inspection considers a wider range of building elements. Where it is safe and reasonable, the surveyor can inspect areas such as:
- Roof spaces
- Floors and subfloors
- Roof structures
- External walls
- Internal walls
- Windows and doors
- Drainage features
- Grounds
- Visible services
- Outbuildings and other permanent structures
The exact scope depends on the property and what can be accessed safely.
Who Needs a Level 3 Building Survey?
A level 3 survey is not necessary for every property. However, it can be a sensible choice when the building has features that require closer assessment.
RICS recommends this level for properties that are large, old, run-down, unusual or significantly altered. It can also suit buyers planning major refurbishment or building work.
You may want to consider a level 3 survey if the property:
- Was built many decades ago
- Has been extended or converted
- Uses unusual construction methods
- Shows signs of damp or movement
- Has visible structural concerns
- Requires major renovation
- Has extensive outbuildings
- Has difficult-to-access roof or floor areas
- Has undergone significant alterations
For a modern home in good condition, a Level 2 property survey may be sufficient. However, unusual risks can make the greater detail of a level 3 inspection worthwhile.
What Does a Level 3 Building Survey Inspect?
The main benefit of a level 3 building survey is the wider and more detailed inspection.
External Condition
The surveyor examines accessible external parts of the building. This can include walls, roof coverings, windows, doors, rainwater goods and other visible features.
The inspection looks for signs of deterioration, movement, water penetration and other defects. The surveyor also considers how different materials and construction methods affect the condition of the property.
Roof and Roof Space
The roof is an important part of the inspection.
Where it is safe and reasonable, the surveyor can enter the roof space and examine the roof structure. Attention is given to areas that may be vulnerable to damage or deterioration.
The survey may consider:
- Roof coverings
- Timbers
- Signs of leaks
- Damp or condensation
- Structural movement
- Insulation
- Ventilation
- Previous repairs
The surveyor will not normally dismantle the roof or remove fixed materials.
Floors and Subfloors
Floor condition can provide useful clues about a property's structure.
A level 3 inspection can involve a more detailed assessment of exposed floors. Where appropriate and safe, the surveyor may inspect accessible subfloor areas and consider signs of excessive movement or deflection.
Potential concerns may include:
- Uneven floors
- Rot
- Damp
- Timber deterioration
- Poor ventilation
- Structural movement
This can be particularly useful in older properties.
Walls and Structural Elements
The surveyor assesses visible walls and other structural elements for signs of defects.
This can include cracking, distortion, damp, movement and deterioration. The survey also considers the likely cause of visible problems where this can be reasonably established.
Importantly, the survey does not mean that every hidden defect will be discovered. Concealed areas cannot normally be opened up without consent and suitable safety conditions.
What Does the Report Tell You?
The report is a key part of a level 3 building survey. It does more than simply list defects.
RICS states that a Level 3 report can describe the property's construction and materials, explain visible defects, identify potential risks from hidden defects and suggest likely causes. It can also outline suitable remedial work and explain the possible consequences of leaving defects unresolved.
This information can help a buyer decide what to do next.
For example, the report may indicate that a defect:
- Needs urgent attention.
- Should be investigated by a specialist.
- Requires planned maintenance.
- Could become more serious if ignored.
- Should be considered before completing the purchase.
This makes the report useful during both property negotiations and future maintenance planning.
Does a Level 3 Building Survey Include Repair Costs?
This is an important question for buyers.
A Level 3 report can provide guidance about repair work and, where agreed as an additional service, may include an indication of costs. However, repair cost estimates are not automatically the same as a contractor's formal quotation.
If major defects are identified, you may need quotations from suitable contractors or specialist reports.
For example, a surveyor may identify signs of roof deterioration. The next step could be obtaining a roofing contractor's assessment and quotation.
This approach gives you a clearer picture of the likely work before making a final decision.
What About Services Such as Electricity and Plumbing?
A common misunderstanding is that a level 3 survey is the same as a full test of every building service.
RICS guidance states that services are not fully tested as part of the standard Level 3 inspection. Instead, visible service installations are inspected and their normal operation may be observed where appropriate, safe and permitted.
This can include observing elements such as:
- Heating systems
- Electrical installations
- Plumbing
- Drainage
- Ventilation
- Visible pipework
- Visible wiring
If the surveyor identifies a concern, they may recommend further investigation by a suitably qualified specialist.
What Is Not Included in a Level 3 Building Survey?
Understanding the limitations is just as important as understanding the inspection.
A surveyor will not normally:
- Open up walls without permission
- Remove fixed floor coverings
- Dismantle building components
- Move heavy furniture
- Remove secured panels
- Carry out specialist tests without agreement
- Provide a full electrical safety test
- Provide a full plumbing inspection
- Guarantee that hidden defects do not exist
The inspection is based on what can be safely and reasonably accessed.
RICS guidance also stresses that inspection limitations should be made clear in the report.
Level 3 RICS Building Survey vs Level 2
Level 3 RICS Building Survey vs Level 2
A Level 2 survey is intended for a wider range of conventional properties. A level 3 RICS building survey provides a more detailed assessment and is better suited to properties where construction, condition or planned work creates greater uncertainty.
| Feature | Level 2 | Level 3 |
|---|---|---|
| Basic condition assessment | Yes | Yes |
| Visible defects | Yes | Yes |
| Maintenance advice | Yes | More detailed |
| Construction and materials | Limited detail | Detailed |
| Roof inspection | More limited | More extensive |
| Floor and subfloor inspection | More limited | More extensive |
| Hidden defect risks | Limited | Detailed consideration |
| Repair advice | Limited | More detailed |
| Suitable for unusual properties | Sometimes | Often more suitable |
| Major renovation planning | Limited | Better suited |
The right choice depends on the property rather than simply its purchase price.

Final Thoughts
A level 3 building survey offers a detailed look at the condition and construction of a property. It can identify visible defects, highlight potential hidden risks and provide useful guidance on repairs and future maintenance.
For buyers purchasing older, unusual or heavily altered properties, the additional detail can provide valuable peace of mind. It may also help you identify issues before they become expensive problems.
However, the survey has limits. It is not a substitute for specialist testing or contractor quotations where these are required.
The best approach is to use the report as a practical decision-making tool. When combined with appropriate specialist advice, a detailed survey can help you understand the property more clearly before committing to the purchase.
FAQs
Is a Level 3 building survey worth it?
For the right property, it can be. It is particularly useful for older, unusual, altered or poorly maintained buildings. The detailed inspection can help identify defects and potential risks that may require further investigation.
Is a Level 3 survey the same as a building survey?
The terms can cause confusion. RICS previously referred to this service as an RICS Building Survey. Under the current naming system, it is called an RICS Home Survey Level 3.
Does a Level 3 survey check for structural problems?
It can identify visible signs of structural movement or other defects and may explain their likely cause where this can reasonably be established. If a specialist structural assessment is required, the surveyor may recommend further investigation.
Does a Level 3 building survey include a valuation?
No. An RICS Home Survey Level 3 does not include a market valuation as standard. A valuation may need to be arranged as a separate service.
How long does a Level 3 survey take?
The time required depends on the size, age, condition and complexity of the property. A larger or more complex building generally requires more inspection time than a straightforward property.
