National Savings & Investments (NS&I) is set to cut the Premium Bonds prize fund rate to 3.3 per cent from 3.6 per cent as of April. The last prize fund rate change occurred in August 2025.
The rate, which is not guaranteed, instead represents the average return of savers who are successful in winning a prize. Interest is not paid on premium bonds. Instead, every 拢1 bond held is entered into a monthly prize draw from which savers can win prizes worth between 拢25 and 拢1mn.
From April the number of prizes available priced between 拢50 and 拢100,000 will decrease, while the number of 拢25 prizes will rise from 2,643,007 in February to an estimated 2,806,003. The odds of winning a prize will also lengthen, from 22,000 to 1 to 23,000 to 1. These odds were last changed in December 2024.
鈥淭his change to the Premium Bonds prize fund rate and odds reflects changes in the wider savings market, and ensures we continue to balance the interests of savers, taxpayers and the wider financial services sector,鈥 Andrew Westhead, NS&I retail director, said.
