Savings giant NS&I has relaunched its Green Savings Bonds, offering a more attractive interest rate. The new bonds, which became available on Wednesday, provide a fixed rate of 3.82% AER (annual equivalent rate) over three years.
Details of the Green Savings Bonds
Originally launched in 2021, Green Savings Bonds aim to support UK government projects focused on sustainability. Here are some key facts about these bonds:
- Minimum investment: £100
- Maximum investment: £100,000 per individual per issue
- Eligibility: Must be aged 16 or older
- Lock-in period: Funds are held for three years and are non-withdrawable
Security and Purpose
NS&I, which serves over 24 million customers, is backed by the Treasury, ensuring 100% security on investments. The Green Savings Bonds are a crucial element of the UK Government’s Green Financing Framework, which was updated in November 2025 to include nuclear energy initiatives.
This new issue represents the eighth offering of the Green Savings Bonds. The previous issue, number seven, paid a lower rate of 2.95% AER.
Expert Opinions on the Bonds
Financial expert Rachel Springall from Moneyfactscompare.co.uk indicated that these bonds may attract savers with significant funds who are willing to accept lower rates compared to other options in the market. She noted, “This latest offering from NS&I will likely be an enticing choice for savers who are content to lock their cash away for three years.”
However, Springall also pointed out that alternative brands offer higher rates, with some deals reaching 4.50% or more. Tandem Bank, for instance, provides a competitive fixed rate of 4.56% AER for a three-year term. Other alternatives include offers from Castle Trust Bank and Gatehouse Bank.
NS&I’s Recent Operational Challenges
In March, NS&I announced plans to compensate bereaved families due to operational issues that had caused difficulties in tracing accounts of deceased customers. The organization informed the Treasury in December about the comprehensive tracing failures.
NS&I has since issued apologies and confirmed that the matters are resolved for both current and new bereavement claims. They have implemented stringent measures to prevent future occurrences.
With the relaunch of Green Savings Bonds at a higher interest rate, NS&I continues to play a pivotal role in supporting sustainable investment while ensuring customer confidence through its secure offerings.
