RICS Level 3 Building Survey: What It Covers, Who Needs One, and Whether It Is Worth It
The most thorough residential survey available in the UK. Here is everything buyers need to know about what a Level 3 building survey includes, who it is designed for, and how it differs from a Level 2 report.
Quick Answer
A RICS Level 3 building survey is an in-depth inspection of a property. It covers all visible and accessible elements in detail, explains defects and their likely causes, and advises on repair options. It is recommended for older properties, properties in poor condition, unusual construction types, or any property where the buyer wants detailed information before purchasing.
What Is a RICS Level 3 Building Survey?
A RICS Level 3 building survey — sometimes referred to as a full structural survey or full building survey — is the most comprehensive inspection available for residential properties. It goes significantly beyond a Level 2 homebuyer report in both the depth of the assessment and the level of detail provided in the written report.
A Level 2 survey follows a standardised format and reports on visible condition using a traffic-light rating system; a Level 3 survey follows a similar report format and traffic-light system, but is more detailed. The surveyor provides a detailed written description of the property’s construction, condition, and any defects they identify — along with an explanation of how serious each issue is, what is likely to have caused it, and what the options are for repair.
At WR Surveying, our Level 3 surveys are carried out by RICS-qualified surveyors with extensive experience in Derby and across the East Midlands, including Derbyshire, Leicestershire, Nottinghamshire, and Staffordshire.
What Does a Level 3 Survey Include?
A Level 3 building survey covers all accessible parts of the property in detail. Here is what the inspection typically assesses:
Structure and Foundations
The surveyor assesses the construction type and materials, the condition of the foundations (where visible), and any evidence of structural movement — including cracking, settlement, subsidence, or heave. A Level 3 survey provides a detailed explanation of any movement identified, its likely cause, and the recommended action.
Roof and Roof Space
Both the external roof covering and, where accessible, the roof space are inspected. The surveyor checks the condition of tiles or slates, ridge tiles, valleys, flashings, guttering, and fascias. Inside the roof space, they inspect the roof structure (rafters, purlins, struts), insulation, and any evidence of damp, rot, or pest damage. This level of detail is rarely available from a Level 2 inspection.
Walls, Floors, and Ceilings
The condition of all internal and external wall surfaces is assessed, including the type of construction (solid, cavity, timber frame), the presence of damp, and any cracking or movement. Floors are checked for springing, sloping, or signs of rot in suspended timber floors. Ceilings are inspected for staining, cracking, or movement.
Windows, Doors, and Joinery
All windows and external doors are assessed for condition, draught proofing, glazing type, and rot in timber frames. Internal joinery such as staircases and fitted cupboards is noted where relevant.
Services (Where Visible and Accessible)
The surveyor provides a general comment on the visible condition of the electrical installation, central heating system, plumbing, and drainage. It is important to note that a building survey does not include specialist testing of services — a Gas Safe engineer, NICEIC electrician, or drainage contractor would be required for a detailed services assessment.
Outbuildings and Grounds
Garages, outbuildings, boundary walls, fences, and paths are assessed where they form part of the property. The surveyor notes their condition and any defects that could affect the main property.
How Does a Level 3 Survey Differ from a Level 2?
RICS Level 2 Homebuyer Survey
A Level 2 Survey provides a clear overview of the property’s condition using RICS condition ratings to highlight defects and areas requiring attention. It is generally best suited to conventionally built properties that appear to be in reasonable condition. The report is more concise and typically costs less than a Level 3 Survey.
RICS Level 3 Building Survey
A Level 3 Survey provides a much more detailed assessment of the property, including its construction, identified defects, likely causes and recommendations for repair or further investigation. It is suitable for all property types, but is particularly recommended for older, altered, extended, unusual or poorly maintained properties. It involves a more detailed inspection and a considerably more comprehensive written report.
The key practical difference is in how defects are reported. A Level 2 survey might flag a crack as Condition Rating 3 and recommend a specialist. A Level 3 survey will describe the crack, assess whether it is structural or superficial, explain its likely cause, describe what a repair would involve, and advise on urgency. This additional depth is valuable when buying a property where you need to fully understand what you are taking on.
Who Should Get a Level 3 Building Survey?
A Level 3 survey is strongly recommended in the following situations:
- The property was built before 1900
- The property shows signs of structural movement, significant damp, or other defects
- The property is non-standard construction — for example, timber frame, steel frame, prefabricated concrete, or a listed building
- The property has been significantly altered or extended
- The property has been empty or unoccupied for a period
- You want the most comprehensive information possible before committing to a purchase
- You are planning extensive renovation or conversion work
A Level 2 survey is often sufficient for straightforward modern properties in good condition. If you are unsure which level is appropriate for your property, contact our team — we are happy to advise.
How Much Does a Level 3 Building Survey Cost?
The cost of a RICS Level 3 building survey varies depending on the size, type, age, and location of the property. As a general guide, buyers should expect to pay more for a Level 3 than a Level 2 — the survey is more time-intensive and the report is more detailed.
It is worth viewing the survey fee in context: a Level 3 survey on an older property might cost a few hundred pounds more than a Level 2, but it can potentially save you tens of thousands of pounds by identifying serious defects before you are legally committed to purchase. For many buyers, the additional detail is money well spent.

What Happens After a Level 3 Survey?
Once your Level 3 survey is complete, your surveyor will provide a detailed written report. This typically covers:
- A description of the property and its construction
- A detailed assessment of every element inspected, with explanations of any defects found
- Recommendations for specialist investigations or further surveys where needed
- Guidance on repair priorities
- A summary of issues to raise with your legal advisors
WR Surveying are also happy to discuss the report with you by phone after it is delivered. This is a valuable opportunity to ask questions and make sure you fully understand what the survey has found before deciding how to proceed.
Common next steps after a Level 3 survey include using the findings to renegotiate the purchase price, asking the vendor to carry out specific repairs before exchange, or instructing specialists — such as a structural engineer or damp specialist — to investigate particular issues in more depth.

Frequently Asked Questions
Is a Level 3 survey worth it for a new-build property?
Usually not. New-build properties are covered by a developer warranty (typically NHBC Buildmark) for the first ten years, and a new-build snagging survey is generally more appropriate. A Level 3 is most valuable for older properties where construction quality and condition are harder to assess.
Does a Level 3 survey include a property valuation?
Not as standard. A Level 3 building survey focuses on condition, not value. If you also need a market valuation — for example for a private sale or separation purposes — a RICS private valuation can be arranged separately.
How long does a Level 3 survey take?
The on-site inspection for a Level 3 survey typically takes longer than a Level 2 — anywhere from two to four hours for an average property, and longer for larger or more complex homes. The written report is then produced after the inspection, and delivery times vary by surveyor and complexity.
Can a Level 3 survey be used to negotiate the purchase price?
Yes. The detailed findings in a Level 3 report — particularly repair cost guidance and priority recommendations — give you a strong, evidence-based foundation for renegotiation. Your solicitor can help you use the findings formally in your negotiations.
What is the difference between a Level 3 survey and a structural engineer’s report?
A Level 3 survey gives a broad overview of the whole property’s condition. A structural engineer’s report focuses specifically on structural elements — foundations, walls, roof structure, or a particular defect — in much greater technical detail. The two are complementary: a Level 3 survey may recommend a structural engineer’s report where significant movement or structural concern is identified.
