How much does a structural survey cost? It depends which of two different products you mean — and the confusion between them costs buyers money every week. A “structural survey” usually means a full RICS Level 3 Building Survey (£600–£1,500), while a structural engineer’s report on a specific defect is a separate, narrower document (£400–£1,000).
How much is a structural survey (Level 3)?
For whole-property inspection, the Level 3 Building Survey is the modern name for the old “full structural survey”. Expect £600–£900 for typical homes, £900–£1,500 for large, listed or complex properties, with London at the upper end. Our structural survey service covers what the inspection includes.
How much does a structural engineer’s report cost?
If you already know the problem — a crack, a sagging floor, a wall you want to remove — a targeted structural engineer’s report typically costs £400–£750 for a single-defect inspection, or up to £1,000+ where calculations or monitoring are involved. Mortgage lenders often request exactly this after a surveyor flags movement.
Which one do you need?
Buying an older property and want everything checked: Level 3 survey. Specific structural concern, lender request, or planned alteration: engineer’s report. Suspected subsidence: start with a subsidence survey, which combines inspection with cause diagnosis. It is common — and sensible — for a Level 3 to recommend a follow-up engineer’s report on one defect rather than paying for both up front.
What drives the fee?
Property size and value, construction type and age, access, and how much reporting detail is required. Always get the scope in writing: the cheapest quote that excludes the roof space or outbuildings is not the cheapest survey.
