The Basics
What Is a Level 3 Building Survey?
A Level 3 survey is the most thorough inspection the RICS offers. It covers structural integrity, damp, the roof, foundations, timber, services, boundaries and outbuildings, and explains not just what is wrong but what to do about it.
Suitability
When Do You Need a Level 3?
More than 80 years old
RICS recommend a Level 3 at this age. Older construction uses techniques and materials no longer in use, and hides problems a Level 2 visual inspection is not designed to find.
Listed buildings
Where alterations carry legal consequences as well as structural ones.
Significantly altered
Extensions and conversions that may not have been carried out properly.
In poor condition or in need of modernisation
Not the same thing as neglected. A probate property is often well kept and still needs upgrading throughout, and it is exactly the case a Level 3 is built for.
Visibly poor condition
Where you can already see something is wrong and need to know how far it goes.
Large or unusual construction
Anything outside standard brick and block, including timber frame and stone.
Planning major renovation
So you know exactly what you are taking on before you commit to the work.
Older or altered property? This is the survey that prices the risk
A Level 3 tells you what needs doing, roughly what it costs and how urgent it is. Get a price for yours in a couple of minutes.

Which Level
Level 2 vs Level 3
Level 3 Building Survey
Everything in Level 2, plus the depth an older property needs.
- Everything included in a Level 2 survey
- Establishes how the property is built and what it is built from
- Detailed defect analysis with the probable cause explained
- Estimated repair costs where a figure can be given
- Specific comments on energy efficiency
- Recommended for anything built before about the 1930s
The Difference
What a Level 3 Does That a Level 2 Cannot
A Level 3 establishes how the property is built and what it is built from. That is what allows a surveyor to diagnose a defect and recommend a remedy, rather than simply record it and refer you on. It is also why it takes longer on site and produces a longer report.
- Establishes how the property is built, what materials are used, and how these will perform in the future
- Describes visible defects, and exposes the potential problems posed by hidden ones
- Outlines the repair options and gives a repair timeline, explaining the consequences of not acting
- Provides an estimate of costs for identified repairs, where practical and agreed in advance
- Provides specific comments on energy efficiency
For Example
The same damp, in two reports
What a Level 3 tells you
The finding, the cause, the fix and the likely cost.
- Damp was found in the front room
- After further investigation, the probable cause is identified
- The remedy is set out, with the consequences of not acting
- An estimate of the cost is given, where a figure can reasonably be reached
The Report
What Is Included?
Energy efficiency
Specific comments on how the property performs and what is worth improving. A Level 3 row on the RICS comparison, and not included in a Level 2.
Detailed condition report
Every element assessed individually, not just the ones that look wrong from the outside.
Structural analysis
Movement, cracking and load-bearing elements examined and explained in detail.
Defect identification
What is wrong, why it has happened, and what needs doing about it.
Repair cost estimates
Indicative costs wherever a reasonable figure can be given without opening things up.
Photographs of findings
So you can see exactly what we saw without having been on site yourself.
Specialist referrals
Where a structural engineer, damp specialist or timber surveyor should take over.
