Green Savings Bonds have been put back on sale with immediate effect today. The new Issue pays 3.82% gross/AER fixed-rate over a three-year fixed term.
Launched in 2021, Green Savings Bonds enable savers to help fund green government projects across the UK. Green Savings Bonds are separate to NS&I’s Net Financing target set by HM Treasury each year. The previous Issue of Green Savings Bonds was removed from general sale on 26 November 2025.
The minimum investment in Green Savings Bonds is £100, with a maximum limit of £100,000 per person for each Issue. Investors need to be aged 16 or over to purchase the Bonds. The full amount deposited will be held for three years and cannot be withdrawn during this time.
Green Savings Bonds are used alongside gilts to raise funds for green projects as part of the UK Government Green Financing Framework, which was updated in November 2025 to include nuclear energy projects.

Notes to editors
- NS&I is one of the largest savings organisations in the UK, offering a range of savings and investments to more than 24 million customers. All products offer 100% capital security as NS&I is backed by HM Treasury.
- 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.
- Net Financing is the measure of the net change of NS&I funds, meaning total inflows from deposits, retention of maturing monies and capitalised accrued interest, less the total outflows from withdrawals and interest or Premium Bonds prize draw payments. A positive Net Financing figure represents a positive contribution to government financing.
