Definitions
Fixed: A fixed rate of interest remains the same and does not change for the duration of the term.
Variable: A variable rate of interest can go up or down throughout the lifetime of a savings account.
AER: AER stands for Annual Equivalent Rate. It shows what the interest rate would be if interest were paid and added to your account each year.
Gross: Gross rates means we will not automatically deduct tax from the interest we pay on money in your account. It’s your responsibility to pay any tax you may owe to HM Revenue & Customs (HMRC).
Tax-free: Tax-free means that interest paid will be free from UK Income Tax and Capital Gains Tax. The tax advantages depend on your individual circumstances and the tax treatment of your ISA may change in the future.
