Frequently asked questions
- Is Plum a bank?
- Plum is an FCA-authorised investing and savings platform — not a bank itself. Cash held in Plum Interest pockets is held by third-party banks (e.g. Investec) with FSCS protection.
- Can I withdraw the deposit I made for the referral?
- Yes — once the referral is confirmed, you can withdraw your initial deposit. The referral reward is separate.
