Overview

The UK Open Government Data API (data.gov.uk) is one of the largest government open data portals, exposing thousands of datasets from UK central and local government agencies. It is powered by CKAN and requires no authentication for searching and browsing datasets. A great starting point for civic tech, journalism, or data science projects involving UK public data.

💡

Beginner Tip

Use the CKAN API at data.gov.uk/api/3/action/ to search and retrieve dataset metadata — then follow the resource URLs to download the actual CSV, JSON, or Excel files.

Common Errors & Troubleshooting

Resource download URL returns 404 UK government agencies sometimes move or retire hosted files while keeping the metadata entry
Check the dataset page on data.gov.uk for an updated link or contact the publisher listed on the page
datastore_search returns no records Most UK GOV datasets are file-based and not loaded into the CKAN datastore
Download the resource file directly using the URL in the resources[].url field and parse it locally
Slow response on large package_search queries Broad searches without filters can return very large result sets
Add specific filters like fq=res_format:CSV or fq=organization:department-name to narrow results
