// WHAT'S IN IT

Inside the dataset

OS Boundary-Line is the definitive set of UK administrative boundaries: countries, counties, districts, wards, parishes, parliamentary constituencies, European electoral regions and unitary authorities. Used everywhere from electoral analysis to council reporting to property aggregations.

We license Boundary-Line under enterprise terms with custom-clipping, full-history versions, and hosting alongside other paid products. Open-data variants exist; partners often prefer enterprise delivery for SLA, support and bundled licensing.

Key features

  • All UK administrative levels
  • Updated bi-annually with boundary commission changes
  • Full historic versions available
  • Standard ONS / GSS coding
