Data Sources & Disclaimer
Last updated: June 2026
AreaIQ is an information service, not an advisory service. All data is provided for general information only. Nothing on this site constitutes financial, legal, medical, or professional advice. Data is sector-level (postcode sector averages) and does not describe individual properties, streets, or addresses. Always verify with official sources and qualified professionals before making decisions.
Data Sources
| Data Layer | Source | Licence | Update Frequency | Limitations |
|---|---|---|---|---|
| House Prices | HM Land Registry Price Paid Data (PPD) | OGL v3 | Monthly | Transaction data only — covers freehold and leasehold residential. New builds and bulk transfers may be excluded. Does not cover properties that have not been sold. |
| Schools | DfE Get Information About Schools (GIAS); Ofsted Management Information | OGL v3 | Termly (DfE) / On inspection (Ofsted) | Ofsted ratings reflect the most recent inspection only and can be revised. Catchment boundaries are set by local authorities and change annually — check with the school directly. |
| Broadband & Mobile | Ofcom Connected Nations; Ofcom Sitefinder | OGL v3 | Annually | Coverage figures are percentage of premises with access — not actual speed. Mobile coverage indicates outdoor and indoor predicted coverage, which may differ from real-world experience. |
| Flood Risk | Environment Agency Flood Map for Planning (England); Natural Resources Wales; SEPA (Scotland) | OGL v3 | Periodically updated by EA | Flood zones are area-level indicators based on modelling. They do not account for local drainage, individual property elevation, or recently installed flood defences. Commission an independent flood risk assessment before purchasing a property in Zone 2 or 3. |
| GP & NHS Dentist | OpenStreetMap (ODbL) / NHS ODS | ODbL / OGL v3 | AreaIQ updates quarterly | Patient acceptance status changes daily. Data may lag reality. Always contact the practice directly or visit NHS.uk to verify current registration status. |
| Energy Performance (EPC) | MHCLG Domestic Energy Performance Certificates | OGL v3 | AreaIQ updates quarterly | EPC ratings shown are sector-level aggregates. Individual property ratings will differ. EPCs are required at point of sale or rental — many older properties may not have an EPC on record. |
| Solar Potential | PVGIS — EU JRC Photovoltaic Geographical Information System | European Commission (open) | Updated periodically by JRC | Solar radiation estimates are based on historical climate modelling. Actual solar yield depends on roof orientation, shading, system quality, and local microclimate. Estimates shown are indicative only. |
| ULEZ / Clean Air Zones | Transport for London (TfL); JAQU Joint Air Quality Unit | OGL v3 | Updated at zone boundary changes | ULEZ and CAZ boundaries can expand or change with little notice. Always verify your vehicle's status at the official TfL ULEZ checker before travel. |
| EV Charging | OpenStreetMap contributors (Overpass API) | ODbL | AreaIQ updates quarterly | OSM is community-maintained. Some charge points may be missing or incorrectly listed. Use Zap-Map or the National Chargepoint Registry for real-time availability. |
| Postcode Geography | ONS National Statistics Postcode Lookup (NSPL); Royal Mail Postcode Address File (PAF) | OGL v3 / Royal Mail | Quarterly | Postcode sectors cover approximately 2,500 addresses on average. Data shown represents the sector as a whole, not any individual address. |
| Local Businesses | OpenStreetMap contributors | ODbL | AreaIQ updates quarterly | OSM business data is community-contributed and may be incomplete, outdated, or inaccurate. Business listings do not constitute endorsement. Always verify business details before travelling or engaging services. |

The AreaIQ Area Score
The Area Score is a proprietary composite metric calculated by AreaIQ from the data sources listed above. It is designed for indicative comparison purposes only and should not be used as the sole basis for any decision.
The score weights multiple factors (schools, broadband, affordability, NHS access, flood risk, and energy efficiency) using a fixed weighting model. Different weightings would produce different scores. The score does not account for factors not in our dataset, including local amenities, social character, transport connections not in open data, or individual property condition.
AreaIQ Ltd makes no representation that the Area Score is suitable for any particular purpose, and accepts no liability for decisions made in reliance on it.
