The FCA maintains a list of companies to avoid. To check if a company is on that list simply visit their website.

If the company does not appear on their list it is no guarantee that company is bona fide or that their intentions are genuine. Investor Protectors provides assistance in the form of “Broker Search” which will give you an informed and researched opinion on any company.
