Data Broker Index

Data brokers in the United Kingdom

No official data broker registry exists in the United Kingdom. As of , this site holds public evidence that 11 companies that are on a US registry operate there; 11 of those are confirmed. Each entry shows its evidence type and source.

The UK Information Commissioner's Office keeps a data protection fee register of every UK data controller. It is not a data broker registry, so appearing on it says a company pays the fee, not that it is a broker.

"Registry" evidence means the company's own US filing gives a headquarters in the United Kingdom. It is not proof the company handles data about people there. See how presence is established.
