The Financial Conduct Authority (
fca.org.uk) have a new facility (Dec. 2025) on their website called
Firm Checker.
If you want to check if a firm is legitimate and what it is legally allowed to do, then this will tell you.
It will also alert you to known 'clone' firms (firms of a similar name or firms pretending to be the real firm).
If you or a relative has been contacted by a firm offering you a 'deal', you should be able to check them out.
Tip: Clone firms are often hard to spot. The number that you are called by can be spoofed. You should find the firms website using a search engine, check that the site looks genuine (e.g. test out all links and pages) and then contact that firm using their email contact address and phone number and ask if the person who contacted you is actually an employee.
Alway pay by credit card (not debit card) even if only part payment is made.
