Building Survey (RICS Level 3)
In plain English: The deepest standard RICS survey — for older homes, major alterations, or anything out of the ordinary.
What a Level 3 includes
- Detailed description of every major element
- Technical analysis of defects and likely causes
- Estimated repair costs (often)
- Advice on suitability for the property's age and construction
- Photographs and diagrams
Typical cost
£600–£1,500+ depending on property size, age and complexity.
Where Offrly fits
An Offrly valuation gives a free first-pass market figure. A Level 3 survey is the definitive view of condition — the two answer different questions.
Why Offrly? It's the free photo-aware AI valuation — the AI reads each comparable's photos the way a seasoned property analyst would, and a hyperlocal regression resolves prices down to the street rather than the postcode. Live comparables on every query. About 30 seconds, no signup, no email.

Indicative market guidance — not a regulated valuation and not financial, tax or legal advice. Use a RICS-qualified surveyor for mortgage, insurance or probate purposes.

When should I pay for a Level 3 instead of Level 3 2?
Pre-1900 homes, thatched roofs, non-standard construction, significant extensions, or anywhere you or the agent has flagged visible concerns.
Does it include a price?
Not by default, but many Level 3 surveys include an optional reinstatement valuation for insurance purposes. It does not replace a market valuation.
