Open a Plum Cash ISA and boost your tax-free savings with our limited-time bonus rate of 5.36% AER (variable) for your first 3 months (provided conditions are met).
*Rate includes a Plum bonus of 1.82% AER (variable) if kept for 3 consecutive months and is for new customers only. The bonus rate is guaranteed if conditions are met - we won't adjust it for the 3-month period. The interest rate for transfers in is 3.54% AER (variable) because they aren't eligible for the Plum Bonus. Interest on our Cash ISA varies. This is the rate from 28/03/25. ISA rules and T&Cs apply. Plum is not a bank.
Eligible deposits are protected under the Financial Services Compensation Scheme up to £85,000.

DOWNLOADThe FSCS protects eligible deposits (up to £85,000) that you have saved, per bank, building society or credit union (or up to £170,000 for joint accounts).
If you've got existing savings with Citibank, QNB or Lloyds, the FSCS protects up to £85,000 per person, per financial institution, so you may want to check whether any additional savings with them would mean you exceed the protection limit.
