From blue lights to streetlights, more than 5,500 public sector organisations across Great Britain use our data for the public benefit. Access to our data has helped deliver local services through town, parish and community councils. It's even been used in preparation for smart cities, and building up environmental resilience.

Public sector organisations rely on OS’s location data to deliver critical infrastructure and services across Britain.

How do I access OS data?

PSGA members can discover and access OS location data, including addressing data, topographic data describing the physical features of the UK, highways, and much more - using the OS Data Hub.

The OS Data Hub is our data platform, it provides PSGA members the data you need in the format you choose to work with. Data can be downloaded, and where possible, APIs can be integrated with user software to enable direct access and allow your organisation to realise the benefits of OS data quicker and more cost effectively.
