Data sources & attribution

HouseSeller surfaces a number of UK government open-data signals on every property page (schools, crime, area price trends) and at the map layer (postcodes, base cartography). Every dataset listed below is reused under the Open Government Licence v3.0 unless otherwise stated. We bulk-ingest each dataset to our own database, refresh on the cadence the publisher recommends, and never present these datasets as our own.

Property prices

HM Land Registry — UK House Price Index (HPI) for area-level price trends on each listing.

Royal Mail data © Royal Mail copyright and database right 2026.
National Statistics data © Crown copyright and database right 2026.
Northern Ireland data: Land & Property Services. Scotland data: Registers of Scotland.

Schools

Get Information about Schools (GIAS) — the daily English schools register (location, phase, status), and Ofsted state-funded schools latest inspections (MI) — current Ofsted ratings keyed by URN.

Contains data from Get Information about Schools (Department for Education) and Ofsted, © Crown copyright. Licensed under the Open Government Licence v3.0.

Sources: get-information-schools.service.gov.uk · Ofsted Monthly Management Information.

Coverage: England only. Ratings shown are from the legacy "Outstanding / Good / Requires Improvement / Inadequate" regime; the new 5-point area-card model introduced on 10 November 2025 is not yet surfaced — those judgements aren't comparable to the legacy ones.

Crime

data.police.uk monthly bulk archive — street-level crime counts aggregated to LSOA, joined with ONS LSOA mid-year population for the per-1,000 residents calculation.

Includes content from the data.police.uk site, supplied by the Home Office and police forces in England, Wales and Northern Ireland. Licensed under the Open Government Licence v3.0.
Source: Office for National Statistics licensed under the Open Government Licence v3.0. Contains National Statistics data © Crown copyright and database right 2026.

Sources: data.police.uk · Nomis (ONS) — dataset NM_2014_1.

Greater Manchester Police data has been incomplete during the GMP IT migration — property pages in that area carry an explicit coverage note rather than treating the absence as "low crime".

Postcodes & geography

Postcode → coordinate and postcode → administrative-area lookups use the postcodes.io service (MIT-licensed open-source code), backed by the ONS Postcode Directory.

Contains OS data © Crown copyright and database right 2026.
Contains Royal Mail data © Royal Mail copyright and database right 2026.
Source: Office for National Statistics licensed under the Open Government Licence v3.0.

Source: postcodes.io. Northern Ireland postcodes (BT…) are carved out of the OGL grant — commercial reuse of NI postcodes requires a separate Royal Mail / LPS NI licence; we only surface NI postcodes that originated from the property listings their owners gave us.

Maps

Background tiles and the geocoding fallback come from the OpenStreetMap project; true travel-time isochrones (when configured) come from OpenRouteService at HeiGIT.
