Pick a property price and get a realistic 2026 cost estimate for each RICS survey level, with guidance on which level fits your property.
Your property
| Level | What you get | Right for |
|---|---|---|
| Level 1 | Traffic-light condition report, no advice | New-build or recent construction in obviously good condition |
| Level 2 | Condition + market valuation + advice on defects + repair cost indications | Standard property built after 1945 in reasonable condition — the mainstream default |
| Level 3 | Full structural survey, detailed defect analysis, extensive advice | Period property, non-standard construction, visible defects, major extension plans |
Mortgage valuation is not a survey
Your lender's valuation is a quick desk-based check (sometimes a drive-by) worth £0-£350 depending on lender and LTV. It is for the lender, not for you — it does not identify defects or guarantee the property is sound. Always commission your own RICS survey separately.
When Level 3 pays for itself
Period property, thatched, timber-frame, listed building, cavity-wall issues, visible movement cracks, or anything over £500,000 where the renovation stakes are high. A £1,200 Level 3 survey that flags £15,000 of hidden defects (and lets you renegotiate the price down) earns 10x its own cost. See the house survey guide for a defect checklist.
Frequently asked questions
Do I need a survey if the lender does a valuation?
Strongly recommended. The valuation is a 20-minute desk check for the lender — it will not catch defects that cost you tens of thousands later.
How long does a survey take?
Site visit is 1-4 hours depending on level. Written report follows in 3-10 working days. Add this to your conveyancing timeline.
Can I use the survey to renegotiate?
Yes. A Level 2 or 3 report with repair cost indications is the standard evidence for a renegotiation. 15-25% of buyers successfully renegotiate after a Level 3 survey.
