Premium Bonds must be held for one full calendar month before entering a prize draw: bonds bought any time in November first enter the January draw. Buying in the last days of a month therefore buys identical draw access for roughly a month less of forgone interest. From the July 2026 draw the prize fund rate is 3.8% at odds of 22,000 to 1.
TL;DR · LAST REVIEWED 25 JULY 2026
- Bonds bought on the 1st and the 30th of the same month enter the same first draw; the early buyer just waited longer earning nothing
- Buying at month end minimises dead money: worth a few pounds per £10,000 moved at current savings rates
- Prize fund rate from the July 2026 draw: 3.8%, odds 22,000 to 1 per £1 bond, up from 3.3% and 23,000 to 1
- Rate changes apply to all existing bonds automatically, so timing a purchase around announcements gains nothing
- All prizes from £25 to the two monthly £1 million jackpots are tax free; maximum holding £50,000
KEY FACTS
- Eligibility rule: one full calendar month of holding before the first draw, held on the first working day of each month
- Prize fund rate 3.8% from the July 2026 draw; 3.3% applied through the June 2026 draw
- Odds 22,000 to 1 per £1 bond from July 2026; monthly prize pot near £437 million
- Minimum purchase £25; maximum holding £50,000 per person including children's accounts
- All prizes tax free, from £25 to two £1 million monthly jackpots
- Withdrawals take 3 to 5 working days with no notice or penalty
How the eligibility rule works
The rule is a full calendar month of holding before the first draw: a bond bought on 1 June and one bought on 30 June both first enter the August draw. The 1 June buyer waited 60 days earning nothing; the 30 June buyer waited 32.
At easy access savings rates around 4% to 4.5%, buying in the last few days of a month rather than the first saves a few pounds of forgone interest per £10,000 moved, every time. The draw access purchased is identical.
The July 2026 rate change
From the July 2026 draw the prize fund rate rose from 3.3% to 3.8% and the odds shortened from 23,000 to 1 back to 22,000 to 1, reversing April's cut and adding over £60 million to the monthly prize pot.
The change applied automatically to every existing bond, so there was no advantage to buying ahead of it, and the same holds for any future move: the rate follows the bonds, not the purchase date. Only the full month rule rewards timing, and only at month end.
What timing cannot fix
The prize fund rate is a statistical average across all bonds, not a guarantee. With median luck, small holdings frequently win nothing in a year, and most holders earn below the headline rate because large prizes pull the average up.
Every £1 bond in the draw carries identical odds regardless of purchase date or holding size. The genuine comparison is against taxed interest elsewhere: for higher rate taxpayers with exhausted savings allowances, tax free prizes at a 3.8% fund rate compare well; for basic rate taxpayers with allowance to spare, a top easy access account above the fund rate frequently wins on expected value.
Buying with the calendar in mind
- Decide the amount against the £50,000 holding cap and the tax free comparison for the relevant tax band
- Time the purchase for the final days of the month to minimise the ineligible holding period
- Confirm the purchase completes inside the month; card and bank transfer cut offs differ
- Diarise the first eligible draw: the one after a full calendar month of holding
- Set winnings to reinvest or pay out, and check for unclaimed past prizes on the NS&I checker

Frequently asked questions
When is the best time of the month to buy Premium Bonds?
The last few days. Bonds held a full calendar month enter the next draw, so a 30 June purchase and a 1 June purchase both first enter the August draw, but the earlier buyer sacrificed nearly a month of interest elsewhere.
How long before new bonds can win?
One full calendar month plus the wait for the draw: bonds bought in November first enter the January draw, held on the first working day of the month.
What is the current prize fund rate?
3.8% from the July 2026 draw, with odds of 22,000 to 1 per £1 bond, up from 3.3% and 23,000 to 1 through the June 2026 draw.
Should I buy before a rate rise?
No timing advantage exists: rate changes apply automatically to all bonds in the draw whenever they were bought.
Are Premium Bond prizes taxed?
No. All prizes from £25 to the two monthly £1 million jackpots are tax free, which is where the product gains most of its edge for higher rate taxpayers.
What are the limits?
Minimum £25 purchase, maximum £50,000 holding per person, winnings reinvestable up to the cap, withdrawals in 3 to 5 days with no penalty.
