Is RICS Level 3 same as old 'Full Structural Survey'?

Effectively yes — Level 3 Building Survey replaced the previous 'Building Survey' / 'Full Structural Survey' nomenclature. Scope similar — comprehensive visual inspection by RICS surveyor. Note 'structural' in old name was misleading — RICS surveyors are generalist surveyors, not Chartered Structural Engineers. For structural-specific questions, Structural Engineer's Report is the appropriate product.

Does a structural survey check foundations?

Visual inspection only — surveyor doesn't excavate. Foundation assessment based on indirect evidence (cracks, movement, age, ground type). Suspected foundation issues escalate to Structural Engineer's Report + possibly soil investigation (£2,850–£5,500 borehole + lab testing) for full diagnosis.

Can a survey confirm if a wall is loadbearing?

Visual inspection + tap-test + loft visit (where accessible) gives strong indication — surveyor will report opinion. Definitive answer needs Structural Engineer's Report or, for minor cases, Engineering Judgement Letter (see [[engineering-judgement-letter-london]]). Don't proceed to wall removal on surveyor's opinion alone — engineer's sign-off mandatory for Building Control.

What Are the Different Structural Survey Categories in London?

London structural survey categories under RICS Home Survey Standard 2021: Level 1 Condition Report £350–£650 (visual, traffic-light condition rating); Level 2 HomeBuyer Report £650–£1,250 (more detail, valuation included); Level 3 Building Survey £950–£2,500 (most comprehensive RICS survey, all aspects); Specific Defect Survey £450–£1,850 (targeted, e.g. subsidence cracks); Structural Engineer's Report £450–£2,850 (structural engineer not surveyor, specific structural questions).

RICS Home Survey Standard 2021

RICS replaced previous survey nomenclature (Homebuyer Report, Building Survey) with three standardised Levels in 2021. Level 1 Condition Report: shortest visual survey, traffic-light condition rating (1/2/3) on building elements + services, suitable for newer property in apparent good condition, no valuation, no advice on repairs. Cost £350–£650 for typical London 3-bed. Level 2 HomeBuyer Report: includes Level 1 plus more detail on defects, market valuation, reinstatement cost for insurance, follow-up advice. Most commonly purchased for conventional property in apparent fair condition. Cost £650–£1,250. Level 3 Building Survey: most comprehensive RICS survey — full visual inspection, defects analysis, repair recommendations, often estimated repair costs, suitable for older/listed/altered/poor-condition property. Cost £950–£2,500.

Specialist + structural surveys

Specific Defect Survey: focused investigation of identified defect (subsidence cracks, damp pattern, roof failure) — surveyor or structural engineer depending on defect type. Output: cause diagnosis + repair recommendations + cost estimate. Useful when Level 2/3 survey flags concern requiring follow-up. Cost £450–£1,850. Structural Engineer's Report (vs surveyor's): qualified Chartered Structural Engineer (IStructE/ICE MIStructE/MICE) — specifically for structural questions: subsidence assessment, crack monitoring + cause analysis, alteration feasibility, foundation adequacy, beam/lintel design verification, party wall structural assessment. Cost £450–£2,850 depending on scope. Engineer's Report carries more weight than surveyor's report for structural lender/insurance questions.

Which to commission when

Purchase of typical post-1960s house, no obvious issues, modern construction: Level 1 or 2 sufficient. Purchase of Victorian/Edwardian terrace, period property, or showing any defect indicators: Level 3 Building Survey — period property complexity warrants comprehensive coverage. Specific concern flagged on prior survey or visual: Specific Defect Survey + Structural Engineer's Report as appropriate. Pre-renovation structural feasibility (can I add loft + extension + remove walls?): Structural Engineer's Report scoping feasibility + likely structural costs. Pre-listing seller's survey (to anticipate buyer queries): Level 3 + remediation any flagged defects pre-marketing. Builderr renovation context: most clients have done Level 2/3 survey at purchase — review report at design stage, commission targeted structural engineer's input where renovation scope intersects with flagged defects.
