NS&I Green Savings Bonds back on sale

Green Savings Bonds have been thrust back into the spotlight after National Savings and Investments (NS&I) have reintroduced the bonds at a competitive rate.

The new issue of bonds boasts a 3.82% AER (annual equivalent rate) over a three-year term. After the initial lukewarm response when they were launched back in 2021 due to the low opening rate, it is clear that NS&I aims to hit the ground running with a competitive rate this time around. Whilst it may be competitive, there are higher rates available, see our Best Buy tables for up to date rates.

Anyone aged 16 or over can invest anywhere from £100 to £100,000 in a Green Savings Bond per person for each issue, meaning that they are accessible to almost everyone, although it is important to note that the money cannot be accessed during the three-year term and the interest is only realised upon maturity.  

What are Green Savings Bonds?

Launched in October 2021 following Rishi Sunak’s 2021 Spring Budget, Green Saving Bonds are a type of three-year fixed savings account available from NS&I. The ‘Green’ part comes from the idea that the funds these bonds raise are then used to fund ethical and environmentally conscious investing such as electric vehicles, public transport, offshore wind farms and solar energy in homes.

Other than that distinction, they are functionally the same as normal fixed rate bonds. They operate like a normal three-year fixed savings account, so the amount you save is locked away until the account 'matures' at the end of the set period. In return, it pays a fixed interest rate, so once the three-year term is over, you'll receive your lump sum savings back in full, plus the interest.  

These bonds form an important part of the UK Government’s Green Financing Framework, complementing the role of gilts in generating funding for specific environmentally focused projects. The framework was revised in November 2025, with its remit widened to cover nuclear energy initiatives.

As a Treasury-backed savings institution, NS&I guarantees full protection on all deposits and supports a customer base of over 24 million people across the UK.

These bonds sit outside NS&I’s annual net financing target, which is determined by the Treasury each year.
