What does a structural engineer's report include? A defined scope; observations from inspection (defects, measurements, photographs); interpretation — probable cause and significance; and recommendations — no action, monitoring, further investigation or specified repair. Reports are scoped to purpose: a lender-condition report answers the valuer's specific query, a pre-purchase report informs the buyer's decision, a claim report addresses cause for insurers, a design/alteration report supports Building Control.
The main report types
- Lender-condition reports — commissioned when a valuation is 'subject to structural engineer's report'; scoped precisely to the flagged item; the mortgage unblocked is the deliverable
- Pre-purchase structural reports — buyer-commissioned depth on flagged or suspected issues; drives negotiation and decision
- Defect/claim reports — cause and significance for insurance or dispute contexts; evidential standards higher
- Alteration/retrospective reports — assessing undocumented past works (removed walls, conversions) toward regularisation
- Monitoring reports — interpreting movement data over time; the 'live or historic' verdict
Reading one properly
Read in this order: scope first (what was and wasn't examined — a rear-crack report is silent on the roof by design, not omission); conclusions next (cause, significance, recommendation — the operative content); observations for the evidence; caveats last, calibrated: standard limitations (concealed elements not opened up, opinions from visible evidence) are professional norms, not weasel words. The phrase pairs that matter: 'historic and stable' vs 'ongoing/progressive'; 'monitor' vs 'investigate further' vs 'repair'; 'no significant structural defect' — the sentence transactions turn on.
Commissioning the right scope
State the purpose when enquiring — lender's exact wording, buyer's specific worry, insurer's request — because scope, depth and addressee follow from it. Under-scoping wastes the visit (a single-crack report can't answer 'is the whole house sound'); over-scoping wastes money (whole-building appraisal to answer one valuer query). Practicalities: reports typically follow inspection within a few working days; recent reports travel best (lenders prefer under 3–6 months); and the appointed professional confirms their qualifications, suitability for the intended use, fee and turnaround before you commit.
