Tracking Automated Government — a Charity-Run Register of 55 Algorithmic Tools Used in UK Public Decisions

In February 2023 the Public Law Project, a UK legal charity, launched the Tracking Automated Government (TAG) register to document automated and algorithmic tools used by public authorities in administrative decisions. It opened with 41 tools and listed 55 by 2025.
Each entry describes how the tool works, the factors it relies on and what is known about its potentially unequal impact. It flags where there is a risk of discrimination and where no Data Protection Impact Assessment or Equality Impact Assessment has been carried out, and can be searched by public authority. Funding of GBP 74,998 from the Nuffield Foundation supports a July 2025 to September 2026 research project by PLP on public-law litigation in the automated state.
Limits: the register includes only tools known to PLP, so it is not a complete inventory, and the sources reviewed do not describe how entries are compiled or independently verified. PLP's October 2026 'Missing Pieces' report found that only 4 of 15 automated systems it identified as still in use appeared on the government's official ATRS register, and that only one of 125 ATRS entries was linked to an Equality Impact Assessment. This shows a civil-society register can reveal gaps that an official register leaves open, but no outcome evaluation of the register itself has been published.
