Data as of Oct 21, 2026 (Olympus publication) · Markdown version
- Payments as each council publishes them under the Local Government Transparency Code 2015, mapped onto one schema. Amounts, dates and names are not adjusted: councils differ in threshold (over £500, over £250 or all spend), in whether amounts include VAT, and in which date they publish (payment, posting or certification). Redacted payees, usually individuals, are returned as redacted and never named. See GET /v1/uk-council-spending/coverage for the councils, files and months loaded.
- Suppliers are grouped by a normalised form of the published name (upper case, punctuation removed, LIMITED as LTD, ...). Grouping is not identity: different organisations can share a name, and one organisation can appear under several. A supplier is linked to a company only through a Companies House number a council file publishes.

- Supplier pages exist only for suppliers paid at least £100,000 in total or by at least 3 councils, and only when the published lines show an organisation (a Companies House or charity number, a legal form such as LTD or PLC, or a public body's name) and the name has no personal title. Sole traders, individuals and payees councils redact get no page.
