Is Key Currency safe and regulated?
Key Currency Ltd is authorised by the Financial Conduct Authority as an authorised payment institution under reference 753989. Client funds are safeguarded in segregated accounts, separate from the firm’s own money. This is not FSCS protection, which does not cover payment institutions. Confirm its status on the FCA Register.
What Key Currency does well
Key Currency holds a 4.9 Trustpilot rating from 3,727 reviews and runs the most personal service model in our table: every transfer is handled by phone with a dedicated dealer, with no app in between. For people who want to talk through timing and be guided by a named contact, that is a genuine strength. It publishes no transfer fees.
Where Key Currency is limited
We could not verify from Key Currency’s own website whether it offers forward contracts or market orders, so we have not claimed that it does — confirm directly with the broker if rate-fixing tools matter to you. It publishes no minimum transfer and, like every broker here, no exchange rate margin. Its 3,727 reviews are fewer than the largest brokers in our table, so while 4.9 is excellent, it rests on a smaller evidence base than a name like Currencies Direct.
