OC Political Donations Analysis showing Christopher Harborne search results — 30 donations totalling £28.8M, largest single donation £9M, bar chart showing Reform UK dominant, donor type breakdown doughnut chart

Follow every pound donated to UK politics since 2001.

The Electoral Commission publishes donation data but the raw register is difficult to navigate — particularly for historical analysis, company cross-referencing or understanding pattern changes over time.

OC Political structures and visualises all 91,000+ records — so you can move from an aggregate party view to a specific company's donation history to an individual MP's declared interests from that company in a few clicks.

Common questions

What donations data does OC Political cover?
OC Political covers all registered donations to UK political parties published by the Electoral Commission since 2001 — more than 91,000 records. This includes the Great Britain and Northern Ireland registers. It covers cash donations, non-cash donations, public funds, visits and loans above the reporting threshold. The data is updated weekly from the Electoral Commission's published register.
Can I search donations by company name?
Yes. Use the Donations Search tab and enter a company name in the Donor field. Results show every donation made under that company name or its registered variants — including donations made via differently-named subsidiaries where the Electoral Commission has filed them under a related name. Corporate donors link directly to their Companies House profile.
Can I see which companies donate to which parties?
Yes. The Donations Analysis dashboard shows total donations by party. Search any company name to see the full split of their donations across parties, values and years. The party breakdown chart shows exactly where every pound went.
How is the Donations Search different from the Analysis dashboard?
The Analysis dashboard shows aggregate statistics — total values, charts, top donors — filtered by year, register and donor/recipient. The Donations Search returns individual donation records, useful when you want to find specific transactions, verify a particular donation or export a list of records matching your criteria.
