How to Report to the FCA
The Financial Conduct Authority (FCA) regulates financial services in the United Kingdom. If you have been targeted by an unauthorised investment firm operating through UK entities, reporting to the FCA is an essential step. No Corinth Group entity holds FCA authorisation.
Check the FCA Register First
Before engaging with any investment firm, check the FCA register at register.fca.org.uk. The register lists all firms authorised to conduct regulated financial activities in the UK. No Corinth Group entity — including Three Tuns Investment Holdings Ltd (company 14242045) and Corinth Management Services Ltd (company 12297863, now in compulsory liquidation) — appears on the FCA register [FCA register].
How to Report an Unauthorised Firm
Report unauthorised firms via fca.org.uk/consumers/report-scam-unauthorised-firm. Your report should include: the entity name and Companies House number; details of the investment products or services offered; copies of any contracts or marketing materials; proof of payments made; and the names and contact details of individuals you dealt with.
FCA Warning List
The FCA maintains a warning list of firms that are not authorised but appear to be conducting regulated activities. Check the warning list at fca.org.uk/scamsmart/warning-list. Your report may result in the entity being added to this list, protecting future potential victims.
Corinth Group UK Entities
Key UK entities in the Corinth Group network include: Three Tuns Investment Holdings Ltd (14242045); Corinth Management Services Ltd (12297863, compulsory liquidation January 2026); and five special purpose vehicles directed by Justinas Kairys, all incorporated on the same date (19 May 2019) [Companies House, UK]. Alec Theunissen served as director across 25+ UK companies in the network.
Complementary UK Reporting
In addition to the FCA, report to: Action Fraud (actionfraud.police.uk) for criminal fraud investigation; Companies House for concerns about company filings; the Insolvency Service for director misconduct in insolvent companies; and HMRC if you suspect tax evasion alongside investment fraud. Filing with multiple agencies increases the likelihood of investigation.
