Imogen BennettNS&I raised rates across five savings accounts from 14 May 2026, with Premium Bonds set to pay an improved 3.80% prize fund rate from the July draw. For the first time in almost three years, the government-backed savings bank is offering UK savers a reason to reassess exactly where their cash is sitting — and whether they are getting the best possible deal.
What NS&I Changed on 14 May 2026
The headline change is Premium Bonds. The annual prize fund rate rises to 3.80% from the July 2026 draw, up from 3.30% since April 2026. The odds of winning per £1 Bond shorten from 23,000 to 1 to 22,000 to 1, adding an estimated 322,000 extra prizes to the monthly draw and increasing the total prize pot by over £60 million, according to the NS&I official rates announcement.
But Premium Bonds are not the only product that improved. NS&I also raised rates on four other accounts simultaneously:
- Direct Saver: up to 3.45% gross/AER — a competitive easy-access rate
- Income Bonds: up to 3.40% gross/3.45% AER — monthly income payments
- Direct ISA: rate increased, maintaining tax-free cash savings appeal
- Junior ISA: rate increased, benefiting families saving tax-free for children
NS&I described the changes as "a response to changes in the wider savings market" and the need to meet its Net Financing target set by HM Treasury. In practical terms: the savings market had grown more competitive, and NS&I moved to ensure it remained a viable option for UK depositors.
How the New Rates Compare to the Wider Market
NS&I's appeal rests on two things that no high-street bank can match: the full government guarantee on every penny deposited — compared with the Financial Services Compensation Scheme limit of £85,000 per person at commercial banks — and the tax-free status of all Premium Bonds prizes.
At 3.45% gross/AER, the Direct Saver is now genuinely competitive with easy-access accounts from major banks, though some challenger banks and cash ISAs still offer slightly more. The relevant question is whether the government guarantee justifies accepting a modest rate difference. For savers with more than £85,000 in cash, the answer is often yes.
For Premium Bonds, the stated 3.80% prize fund rate is a statistical average, not a guaranteed return. Analysis from independent financial sites including MoneySavingExpert notes that actual returns vary significantly: holders of large Bond portfolios will achieve returns close to the stated rate over time, while smaller holders may see annual returns well below it due to the lottery distribution of prizes. All prizes are completely tax-free, however — a meaningful advantage for higher-rate taxpayers whose Personal Savings Allowance is reduced to £500, and for additional-rate taxpayers who have no allowance at all.

3 Moves UK Savers Should Consider Now
Move 1: Review whether Premium Bonds make sense for your tax position.
If you pay income tax at 40% or 45%, the tax-free prize structure of Premium Bonds may outperform a nominally higher-rate taxable account once tax is applied to interest income. A wealth manager can model this accurately using your current income, the Personal Savings Allowance you actually hold, and the realistic prize frequency at your Bond holding level. This is rarely a simple calculation.
Move 2: Check whether your easy-access savings are still earning.
If you hold cash in a legacy savings account opened before 2024 or 2025, the rate may have stagnated well below NS&I's new 3.45% Direct Saver. The 14 May changes are a natural trigger to audit where your cash actually is and what it is earning. A wealth manager or independent financial adviser can run a savings audit across your accounts in a single session.
Move 3: Consider the Junior ISA for children's savings.
The Junior ISA rate increase means NS&I now offers families a government-backed, tax-free option for saving from a child's birth to age 18. Parents who opened a Junior ISA elsewhere during the lower-rate era should compare current rates. Our 2026 guide to Junior ISA choices for UK families explains the key decisions.
Should You Lock In at NS&I's Fixed Rate?
NS&I also offers fixed-rate bonds paying up to 4.5% for savers able to commit money for one to two years. That rate is significantly above the easy-access Direct Saver and makes NS&I competitive with the top end of the fixed-term market — while retaining the full government guarantee.
The trade-off is that your money is inaccessible during the fixed term. Given current Bank of England base rate expectations, a wealth manager can help model whether locking in at 4.5% for one year makes more sense than holding in an easy-access account at 3.45% while waiting for conditions to change.
When to Take Professional Advice
The May 2026 NS&I changes are broadly positive for UK savers, but they do not make NS&I automatically the best choice for every pound of cash savings. Tax situation, access requirements, existing account structure, and wider financial planning all shape the right answer. For straightforward holdings under £85,000 with no complex tax position, the Direct Saver and Premium Bonds are worth considering directly. For larger cash holdings or higher tax bands, independent advice will almost certainly improve your outcome.
