data.gov.uk
data.gov.uk is the single place to find open data published by central government, local councils, and public bodies across the UK. Each entry points to the data itself along with metadata describing what it contains, who published it, and how often it is updated.
The datasets arrive in many formats, most often CSV, JSON, and XML, and a good number are served through APIs so you can pull fresh figures on demand. Coverage is broad: spending records, crime statistics, planning data, school performance, transport timetables, and much more.
For a RAG system that answers questions about UK public services, policy, or local data, this is a natural starting point. Because everything is published under the Open Government Licence, you are free to reuse it in commercial and non-commercial projects as long as you credit the source.
