Analysis
What this data actually tells you
Financial and Insurance Activities in the UK runs on an authorisation system entirely separate from company registration. Nearly all financial-service activities require authorisation or registration with the Financial Conduct Authority (FCA), and the FCA’s Financial Services Register — redesigned to make firms, individuals and other regulated bodies easier to search, and last updated 13 February 2026 — is the definitive public record of who currently holds, or has ever held, that authorisation.
The Register goes beyond a simple yes/no: it shows the specific permissions a firm holds, whether it’s covered by the Financial Ombudsman Service or the Financial Services Compensation Scheme, and it explicitly flags firms known to be operating without authorisation or running clone scams that falsely claim a genuine firm’s identity. For verification, checking a UK financial-sector counterparty means searching the FS Register directly — a company can be validly incorporated and still hold no FCA authorisation, or worse, be impersonating one that does.

Who uses United Kingdom financial and insurance activities ownership data
The three checks this sector's data is most often run for.
FCA Financial Services Register check
Nearly all UK financial-service activities must be authorised or registered with the FCA — the Financial Services Register (last refreshed 13 February 2026) is the authoritative public record of every currently or previously approved firm and individual, separate from company registration.
Unauthorised-firm and clone-scam screening
The FS Register specifically lists firms known to be offering regulated services without authorisation, including scams falsely claiming to be a genuine authorised firm — a distinct fraud-screening use the company register alone can’t provide.
Permissions and scheme-coverage check
The FS Register shows exactly which regulated permissions a firm holds and whether it’s covered by the Financial Ombudsman Service or the Financial Services Compensation Scheme — granular detail beyond a simple authorised/unauthorised flag.
