Quick Answer
National Savings and Investments (NS&I) is increasing the Premium Bonds prize fund rate from 3.30% to 3.80% tax-free, effective from the July 2026 draw. At the same time, the odds of any single £1 Bond winning a prize shorten from 23,000 to 1 down to 22,000 to 1.
Variable savings rates were also raised on May 14, 2026. The Direct Saver moves to 3.45% gross/AER, Income Bonds to 3.40% gross / 3.45% AER, the Direct ISA to 3.80% tax-free AER, and the Junior ISA to 3.70% tax-free AER.
What Premium Bonds Holders Should Notice
Premium Bonds do not pay interest. Instead, the prize fund rate determines the total pot of monthly prizes shared across all eligible Bonds. A higher prize fund rate plus shorter odds means two things at the same time:
- The pot is bigger.
- It is sliced into more prizes per month.
For the July 2026 draw, NS&I projects roughly 322,000 extra prizes compared with May, and a monthly pot of around £436.8 million (over £60 million higher than before). At the top of the prize ladder, July is expected to include 12 additional £100,000 prizes, 24 more £50,000 prizes and 49 more £25,000 prizes than the previous month.
What the New Odds Actually Mean
Shortening the odds from 23,000 to 1 down to 22,000 to 1 sounds small in isolation. Across the more than 22 million holders and tens of billions of Bonds in circulation, the effect is significant. Each individual £1 Bond has a slightly higher monthly chance of winning, and the pool of distributed prizes grows.
For a holder with the maximum £50,000 invested, the change does not guarantee any individual win, but it does meaningfully shift the expected annual prize return upwards.
The Full Rate Table
Here is what NS&I changed in one place. The variable rate changes took effect on May 14, 2026. The Premium Bonds change applies from the July 2026 draw.
| Product | Previous Rate | New Rate |
|---|---|---|
| Premium Bonds prize fund rate | 3.30% tax-free | 3.80% tax-free (from July 2026 draw) |
| Premium Bonds odds (per £1 Bond) | 23,000 to 1 | 22,000 to 1 |
| Direct Saver | 3.05% gross/AER | 3.45% gross/AER |
| Income Bonds | 3.01% gross / 3.05% AER | 3.40% gross / 3.45% AER |
| Direct ISA | 3.50% AER tax-free | 3.80% AER tax-free |
| Junior ISA | 3.55% AER tax-free | 3.70% AER tax-free |
Why NS&I Is Raising Rates Now
NS&I has a yearly Net Financing target set by HM Treasury. For 2026-27 that target is around £15 billion. To hit it without breaching its "balanced market" obligations (not pricing so aggressively that it pulls money out of high street banks unfairly), NS&I monitors competitor rates and adjusts.
Andrew Westhead, NS&I's Retail Director, framed the change as a response to wider market conditions. Translation: best buy easy access rates from challenger banks have crept up, so NS&I lifted its own rates to stay competitive without overshooting.
The Tax-Free Angle
The headline 3.80% on the Direct ISA matches the new Premium Bonds prize fund rate, but the two work very differently.
- Direct ISA. Pays the rate as ordinary interest, inside the ISA wrapper. Every holder gets the same return on the same balance.
- Premium Bonds. Pays out as a random distribution of tax-free prizes. Two holders with the same balance can have very different annual returns depending on luck.
For higher rate taxpayers who have already used their Personal Savings Allowance, Premium Bonds and the Direct ISA are both attractive because the return is tax free. Basic rate taxpayers with smaller balances get less of an edge from the tax-free wrapper, so the Direct Saver and Income Bonds can be competitive even at lower headline rates.
Is Now the Time to Top Up?
The Premium Bonds maximum holding is £50,000 per person. At a 3.80% prize fund rate, the long term expected (not guaranteed) prize return on a maxed out holding works out to roughly £1,900 a year in tax-free prizes, though the actual outcome will be lumpier than that because of the prize ladder.
NS&I products are 100% backed by HM Treasury, which is a different (and stronger) protection than the £85,000 FSCS limit applied to bank deposits. For savers with very large cash balances, that backing alone can justify keeping a portion of savings here.
The Takeaway
NS&I's May 2026 update is one of the most savers friendly the agency has issued in the past few years. Premium Bonds become more attractive on both prize fund rate and odds. The Direct ISA matches that 3.80% as guaranteed interest in a tax-free wrapper. Easy access rates on the Direct Saver and Income Bonds are now competitive with the wider market. If your savings strategy includes NS&I, this is a good week to revisit your allocation.
