What each council published, by year

These councils are not comparable with one another. They hold different numbers of years, publish above different thresholds and buy different things, so a larger figure here means more was published and read, not that one council spent more freely than another. An empty cell is a year not held, never a year of nothing.

The largest payments published

A description is the council's own wording on the row. A large single payment is often a scheduled settlement of many smaller invoices, and this site does not know which of these are.

Which councils and years contributed

Covers 51 councils and 7 financial years in the AI DOGE corpus. Councils and years not listed have not been ingested and are not zero.

A council that is not on this list has not been ingested for this supplier. That is a statement about this site's holdings and not about the council, and it is never a zero.

The council pages behind these figures

How this page was built

A supplier gets a page of its own when ten or more councils published a payment to it, or when at least £10m was published to it in a single financial year. That cut is a size, not a judgement, and it is applied the same way to every supplier.

Names are matched across councils by a canonical form of the supplier string each council published. Two councils spelling the same company differently are joined; a company and its subsidiary are not, unless the councils wrote the same name. Payments a council withheld are counted in that council's own totals and are on no page as a name. A Companies House number, where one is shown, comes from this site's own name match and plays no part in joining councils' payments together.
