Site-specific flood risk · England
Strata Flood turns a postcode into a conveyancing flood report or a desk-study Flood Risk Assessment in seconds — built on the authoritative national flood data for England, with a clear conclusion your client can act on.
Built on authoritative national data and independently validated — not a licensed third-party model, and not a black box.
Two products, one engine
Conveyancers get a fast, defensible flood search today; developers and consultants get an automated desk-study FRA with competent-person review. Both run on the same engine — a clear, auditable answer in seconds.
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, drawn from the authoritative national data, with a competent person assessing and owning the conclusion.
How it works
No black box. Every rating rests on an authoritative source, and every figure can be traced back to it on request.
The address is resolved to its exact coordinates and screened against the national flood data — in milliseconds.
Every flood source is assessed against authoritative data and high-resolution terrain — consistently, and the same way every time.
The source ratings produce 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 is built on authoritative data and gives you a conclusion you can audit — on finer terrain, in seconds.
| Strata Flood | Established providers | |
|---|---|---|
| Underlying data | Authoritative (Environment Agency & Ordnance Survey) | Licensed third-party models |
| Terrain resolution | 1 m resolution | Metre-scale |
| Every figure traceable | Yes — fully auditable | Black box |
| Turnaround | Seconds, on demand | Next-day / batch |
| Validation | Independent & auditable | Provider benchmarks |
Confidence
Every report is built on authoritative national data, independently validated, and backed by a full audit trail — so the conclusion holds up to scrutiny.
Where a river site needs a defensible design level for planning, we issue it provisional and refer it for competent-person review until it is fully validated — we don’t publish a number we can’t stand behind.
Where we stand
Conveyancers and planners carry the liability for what a report says. So we’re explicit about what is final, what is provisional, and what is indicative — and we label every rating as exactly what it is.
Tidal and Flood Zone 1 assessments are issued final and instant. For river (fluvial) sites that need a defensible design level, we issue an instant interim and mark it provisional until it is fully validated — rather than printing a number we can’t evidence.
The Strata Flood Risk Rating is built from authoritative data by our own method — it is not FloodScore™ or any insurer’s classification, and it uses no licensed risk-pricing data. The insurability view is an indicative read from the risk bands and the public Flood Re rules, not a quotation. Groundwater is assessed to screening grade and shown as indicative — never dressed up as a validated rating.
