What is a Cash ISA?

A savings account where every penny of interest is yours to keep

A Cash ISA works just like a regular savings account with one important difference. The interest you earn is completely free of UK income tax. No forms, no declarations. Just your money, growing faster.

  • Interest paid at the end of the tax year directly into your account
  • Top up any time up to the £20,000 annual limit
  • Withdraw your money whenever you need it
  • Open to any UK resident aged 18 or over
  • No limit on your total pot size. Keep growing it every year

Membership eligibility criteria apply.
