A real report, start to finish.
Open a worked example — the verdict, the source breakdown, the professional opinion, and the full data provenance.
Deterministic · OGL-sourced · fully auditable
Property-level flood reports and assessments for UK conveyancing and planning — built entirely on Environment Agency and Ordnance Survey data, every figure traceable to its source and validated against measured truth.
No licensed third-party model. No fitted corrections. No machine-inferred values. Just the authoritative data, assessed by a deterministic method and validated against measured truth.
Four products, one engine
Conveyancers get a fast, defensible flood search. Developers and consultants get automated fluvial, groundwater and drainage assessments their own competent person adopts and signs. All run on the same deterministic, zero-data-fee engine.
A property-level screening of every principal flood source, with a clear Passed / Further Action conclusion and a professional opinion ready for the report on title.
An automated desk-study FRA: property-specific present-day and climate-adjusted design flood levels from authoritative data and 1 m LiDAR — produced for your competent person to review, adopt and sign under their own professional indemnity. On sign-off, it is their FRA.
An automated groundwater desk-study: BGS susceptibility, superficial geology, aquifer designation and recorded groundwater flooding, resolved to a clear risk class — produced for your competent person to review, adopt and sign.
Groundwater is a distinct hazard — a GWFRA complements a fluvial FRA; the two are not comparable.
An automated surface-water drainage assessment: runoff rates and volumes from open catchment and soil data, sizing attenuation and a sustainable drainage strategy — produced for your competent person to review, adopt and sign.
How it works
No black box. Every rating is derived by a stated rule from a named open dataset, and every figure can be traced back to its source on request.
The property is pinned to Ordnance Survey mapping and the Environment Agency flood datasets at its exact coordinates.
Each flood source is classified deterministically against authoritative data and 1 m LiDAR terrain — no inference, no fitted corrections.
A stated rule turns the source ratings into a clear conclusion, with a professional opinion and an audit trail behind every number.
The difference
The established providers lean on licensed models and a consultant’s word. Strata Flood shows its working — and runs on finer terrain at a structurally lower cost.
| Strata Flood | Established providers | |
|---|---|---|
| Underlying data | EA & OS authoritative, OGL | Licensed third-party models |
| Terrain resolution | 1 m LiDAR · ~0.15 m | Global DEM · metre-scale |
| Every figure traceable | Yes — to named dataset | Black box |
| Turnaround | Seconds, on demand | Next-day / batch |
| Data licensing cost | None — OGL | Per-report fees |
| Validation | Measured gauges & detailed models | Provider benchmarks |
Validation
Strata Flood’s derived levels are validated against independent Environment Agency river-gauge records and detailed hydraulic models, using the UK-standard statistical method.
