  • Access to your investment after three years.

  • The minimum investment in Green Savings Bonds is £100 with a maximum limit of £100,000 per person per Issue. Investors in previous Issues can invest in subsequent Issues.

  • AER stands for Annual Equivalent Rate and enables the comparison of interest rates from different financial institutions and across different products on a like-for-like basis. It shows what the notional annual rate would be if interest was compounded each time it was credited or paid out. Where interest is credited once a year, the rate quoted and the AER will be the same.
  • Gross is the taxable rate of interest without the deduction of UK Income Tax.
