About this site

UK Rates & Thresholds republishes changing official UK figures in one consistent, dated, machine-readable format. Every figure links to its official source and records when we last checked it.

Corrections

Spotted an error? Every page shows its source — if we disagree with the official source, the official source wins and we correct fast. A public correction log will appear here.

For machines

Per-figure JSON at /api/v1/<id>.json, the full dataset at /api/v1/all.json, changes at /feed.xml. An MCP server for AI agents is included in the repository.

This is data, not advice. Figures are republished from official sources with links and dates — always verify with the linked official source before acting.
