You can earn a 3.40% AER (variable) reward rate on your Simple Saver if you have either:
a balance above £0 in a qualifying Moneybox account (ISA, Lifetime ISA, Junior ISA, or Pension)
a Reward Savings Account.
If your balance in your Lifetime ISA drops to £0, you are eligible to keep the reward rate for 12 months or until a later period at our discretion. We'll give you 14 days notice if this changes.
