Area intelligence for UK property.

OneGoodArea gives lenders, insurers and property platforms the official figures behind any address: crime, deprivation, prices, schools, transport and flood. Sourced, versioned, delivered by API and MCP.

Behavioural data tells you how a place performs. OneGoodArea tells you what the place is and what could go wrong there. For any address in Great Britain, the structural picture from official sources, with every figure sourced, scored and reproducible.

Why it holds up

Provenance

Sourced, not modelled

Every figure is computed from a named official dataset and records its source, release date and licence, so it can always be traced and defended.

Determinism

The same input, the same output

Figures are derived by defined, repeatable computation. The methodology is version-stamped on every response and can be pinned per customer.

Confidence

Honest about its limits

Every value carries a confidence level and a plain reason, so a thin sample or a coverage gap is visible rather than hidden.

Who it is for

One layer, six workflows. The same signals, scored and delivered the way each buyer needs them.

Area risk your actuary can audit, monitored continuously.

Per-dimension scores with confidence, not a black box. Save your weighting once, score every quote against it, and get a signed webhook the day a tracked area moves materially.

Flood and crime as inputs

Environment Agency flood-risk exposure and live warnings, police.uk crime, with a confidence on every value.

Your weighting, saved

Score every quote against the same composite, version-pinned for the life of the book.

Portfolio drift

A signed webhook when a tracked area moves materially, not a monthly re-run.
