Authority & Data Provenance
We believe in radical transparency. Every data point in a Postcodewise report is sourced from official and authoritative national registries.
Office for National Statistics (ONS)
Government OfficialThe ONS provides the baseline for UK societal understanding. Postcodewise uses 2021 Census outputs for population, density, age profiles, ethnicity, and household composition. Deprivation and affluence-style scores are kept separate and come from official IMD sources rather than ONS census tables.
Impact on Decision
Understanding Office for National Statistics (ONS) data helps you verify population without relying on hearsay.
DLUHC / OpenDataCommunities (English IMD)
Government OfficialDeprivation summaries for England resolve through Ministry of Housing, Communities & Local Government open tools (imd-by-postcode on Open Data Communities): overall IMD rank plus domains such as income, employment and health.
Impact on Decision
Understanding DLUHC / OpenDataCommunities (English IMD) data helps you verify index of multiple deprivation deciles linked to postcode without relying on hearsay.
data.police.uk
Public SafetyPulling from the National Police API, we analyze monthly crime logs categorized into 14 distinct types. By comparing current incident volumes with a 6-month trailing average, we provide a mathematical trend (increasing or decreasing) that goes beyond simple static counts.
Impact on Decision
Understanding data.police.uk data helps you verify street-level crime incidents and historical outcomes without relying on hearsay.
Environment Agency
EnvironmentalFlood risk is a primary concern for property buyers. Our system checks the Environment Agency's live warning system and long-term risk models (Zones 1, 2, and 3) to alert you to active fluvial or surface water threats in your exact vicinity.
Impact on Decision
Understanding Environment Agency data helps you verify real-time flood alerts and risk mapping without relying on hearsay.
DEFRA & UK-AIR
Public HealthWe connect to DEFRA's UK-AIR monitoring network to provide the Daily Air Quality Index (DAQI). This measures five key pollutants. A score of 1-3 is low (good), while anything above 7 indicates high pollution levels that may impact public health.
Impact on Decision
Understanding DEFRA & UK-AIR data helps you verify active air quality monitoring for no2 without relying on hearsay.
Department for Education (DfE)
InstitutionalEducation data is sourced from the DfE's "Get Information About Schools" service. We track Ofsted outcomes and pupil-to-capacity ratios. Factual insight: Areas with "Outstanding" schools typically see higher property demand and price resilience.
Impact on Decision
Understanding Department for Education (DfE) data helps you verify school performance without relying on hearsay.
PlanIt Open Data
InfrastructurePlanIt aggregates data from hundreds of local planning authorities. We use this to show you "Live Growth"—new building permits, extensions, and commercial changes. This is a leading indicator of an area's future development potential.
Impact on Decision
Understanding PlanIt Open Data data helps you verify regional and localized planning application aggregations without relying on hearsay.
OpenStreetMap
Open DataWithin-postcode neighbourhood features (shops, greenspace proxies, chargers) query OpenStreetMap via the public Overpass API. OSM © contributors; licence ODbL where map data appears.
Impact on Decision
Understanding OpenStreetMap data helps you verify amenity points without relying on hearsay.
Ofcom
RegulatorBroadband availability and headline mobile coverage draws on Ofcom-published material (subscription API keys in production deployments, and optional Fixed Postcode Open Data CSV imports under OGL for offline aggregates).
Impact on Decision
Understanding Ofcom data helps you verify fixed-line and mobile postcode-level connectivity without relying on hearsay.
Integrity Disclaimer
While Postcodewise aggregates data from authoritative sources, we serve as an interface for public interest. Local data is subject to reporting lags from primary sources (e.g., Police data typically has a 2-month delay). We recommend users cross-reference critical life decisions with the primary government portals listed above.
