Signals

UK area data your product can rely on.

Bring crime, deprivation, property, schools, amenities, transport and environmental data into your product through one API. Every signal is confidence-rated and linked to its source.

Every signal, ready to build on.

One consistent shape, national context, confidence and a source on every value. The same four guarantees behind every number we return.

One consistent shape

Every signal returns in the same structure, whatever source or country it came from. Integrate once and read every category the same way.

Placed in national context

Every value ranked against comparable areas, so a number means something on its own.

Confidence on every value

Know how solid each number is before you ship it.

Traceable to its source

Every number links back to the official dataset it came from, ready to cite.

One API · every category · three nations

One source of truth for every UK area.

The same API across three nations

England, Wales and Scotland behind one endpoint, each signal reported in its own country's official index. No separate integrations to build or keep in sync.

Versioned, so numbers never move

Every response is stamped with the engine version that produced it. Replay a call months later and you get the exact same figures, so what you ship stays reproducible.

GET/v1/area/{postcode}

Sourced, comparable, confidence-rated and versioned. Everything a product team needs to build on UK area data without owning the pipeline.

The Signals workspace

Built for the workflows you already run.

The same consistent area data behind the features you ship, the comparisons you make, the decisions you defend and the plumbing you would rather not maintain.

Less integration to build. Fewer datasets to babysit. More decisions grounded in area data you can trust.

Enrich

Add local-area context to listings, applications, reports and customer journeys.

Compare

Compare any two areas on the same national scale, not isolated numbers.

Decide

Bring consistent evidence into research, underwriting, risk and site selection.

Replace the plumbing

Work with one API instead of sourcing, cleaning and monitoring several public datasets.

Frequently asked

Signals, answered.

Which areas do you cover?

Every small area (LSOA and its equivalents) across England, Wales and Scotland. Send a postcode or an area code and you get the neighbourhood back.

Where does the data come from?

Official public sources: police.uk, HM Land Registry, the IMD, WIMD and SIMD deprivation indices, official education datasets, OpenStreetMap and the Environment Agency. Every value links back to the source it came from.

How are England, Wales and Scotland handled?

Each country is reported in its own official index, IMD in England, WIMD in Wales and SIMD in Scotland, inside one consistent response shape, so you integrate once.

How often is the data updated?

Each category follows its own cycle: crime and property monthly, deprivation on official release, the rest as their sources publish. Every response says when each value was observed.

What does the confidence rating mean?

Every value carries a confidence level based on how complete and recent the underlying data is, so your team can decide how to use it.

Are the numbers stable over time?

Yes. Every response is stamped with the engine version that produced it, and replaying the same request returns the same figures.

How do I access it?

A REST API, or the MCP server so you can call it from your code or ask in plain English through your AI tools.
