What you should know:
  • Minimum Deposit £1,000
  • Partial withdrawals and additional deposits are not allowed after the Start Date. Early closure will result in an Early Closure Charge equivalent to 90 days’ Tax-free interest. If the Early Closure Charge is greater than the Tax-free Interest you've earned, the charge will be reduced to ensure you get back at least the amount you deposited at the Start Date.
  • The Fixed Rate ISA start date is 12th December 2016. Up until the start date interest will be paid at the same interest rate as during your term
  • Save up to £15,240 Tax – free in your Fixed Rate ISA for 2016/2017 tax year between 18th October – 9th December 2016.
