What Is a RICS Level 3 Building Survey?
A RICS Level 3 Building Survey, previously known as a Full Structural Survey, is the most comprehensive property survey available in the UK.
It is designed for buyers who need a deep understanding of a property’s structure, condition and long-term risks.
What Does a Level 3 Survey Include?
Surveyors spend several hours on site, examining:
- Roof structure, coverings and loft spaces
- Walls, beams, joists and structural supports
- Subfloor areas, basements and cellars
- Signs of movement, subsidence or settlement
- Damp, timber decay and pest infestation
- Insulation, ventilation and heat loss
The final report includes photographs, explanations of defects, likely causes, and guidance on repair options and urgency.
When Is a Level 3 Survey Recommended?
A Building Survey is strongly advised for:
- Homes over 50 years old
- Properties with visible defects
- Non-standard construction (timber frame, stone, thatch)
- Buildings with major extensions or alterations
- Homes you plan to renovate
Why This Survey Matters
A Level 3 survey provides clarity on serious structural risks and long-term costs that other surveys may not detect. For older or complex homes, it offers the highest level of protection before purchase.
