Britons are being reminded to check their Premium Bonds holdings as soon as possible due to "more than £100million in prizes is currently unclaimed" by savers, according to analysts.
This latest savings warning comes ahead of National Savings and Investments' (NS&I) announcement of the first Premium Bonds winners for the New Year on January 3, 2026.
Unlike traditional savings accounts, Premium Bonds do not have a set interest rate attached to them with NS&I customers instead enrolled in monthly cash prize draw.
Premium Bond holders are able to win lump sums of £10,000, £50,000 and £100,000; but famously two lucky individuals take home £1million every month under the lottery.

Nicola Morgan, a personal finance expert at Confused.com, broke down why bond holders need to take action in order to ensure they are receiving any winnings from NS&I.
She explained: "Premium Bonds are a popular way to save, but it can be easy to forget about them once they’re set up. So, it’s not surprising that over £100million in prizes is currently unclaimed.
"With millions of people holding bonds, there’s a good chance some have money waiting for them and don’t realise it. Every month, two Premium Bond holders wake up to find they won £1million each.
"If you’ve ever bought Premium Bonds, it’s worth taking a moment to check in on them. All you need is your NS&I holder’s number or account number, and you can use their prize checker app or website to see if you have any winnings. If you’re not sure of your details, you can speak to the NS&I who can help you recover them."
Outside of Premium Bonds, the savings expert outlined other ways people can bolster their finances in 2026 with ISAs and budget management being New Year's resolutions
Ms Morgan added: "Cash sitting in loyalty points. Many of us have unused rewards in supermarket, bank, or travel apps. These can often be exchanged for gift cards, discounts, or cash.
"Cutting back on unused subscriptions. Check your direct debits and app store payments. Cancelling services you no longer use could instantly free up extra cash each month.
"Making the most of your cash ISA: savings in a cash ISA are tax-free, and with some accounts now offering over four per cent interest, it’s one of the simplest ways to grow your money."
