Most winners can check if they won a prize in the most recent prize draw from the start of the month, via the NS&I prize checker. But the two £1 million jackpot winners find out slightly earlier.

Jackpot winners should receive a visit from Agent Million, an anonymous NS&I employee who travels up and down the country to tell winners of their newfound wealth.
Their identity is hidden to protect the privacy of winners, as unexpectedly receiving £1 million is likely to change their lives.
While you may already know how Premium Bonds work, we lift the lid on some frequently asked questions about how Premium Bonds winners are notified of their prizes.
How are Premium Bonds prize winners notified?
MoneyWeek: Do all winners get an email saying 'you've just won!', regardless of whether it's £25 or £100,000?
NS&I: Customers who are signed up to be notified of any prize wins via email are notified in this way, regardless of the amount. Any email that Premium Bonds customers receive notifying them of a win does not include the value of the prize. The email notification encourages them to check how much they have won via the prize checker app, online prize checker or on an Alexa-enabled device.
MoneyWeek: What happens with customers who have won a high-value NS&I prize?
NS&I: Customers winning prizes worth between £10,000 and £100,000 are sent a prize claim form in the post. This asks them how they would like their prize paid. For example, they can choose to have their prize paid directly into their bank account or automatically reinvested into more Premium Bonds.
MoneyWeek: How do winners get told when they’ve won the £1 million jackpot?
NS&I: These customers receive a visit from “Agent Million”. This person is an NS&I employee who travels the country to give our lucky jackpot winners the good news. We actually have five Agent Millions. In total, since 1994, there have been around 20 Agent Millions.
MoneyWeek: Who is Agent Million?
NS&I: We keep their identities secret – this is important for the privacy of both our Agent Millions and our winners. Winning £1 million is life-changing, so when Agent Million informs the winners, secrecy ensures that sharing this news is a choice for them.
Our Agent Millions are based in Lytham St Annes (in Lancashire), the home of Premium Bonds, so they do have to travel as well as spend the odd night away from home. Although they are sworn to secrecy about the role they perform, they may tell certain family members or loved ones about it for practical reasons. However, they must keep their role secret from friends and colleagues who do not need to know.
MoneyWeek: Do they always visit the winners in person?
NS&I: Our Agent Millions always visit £1 million Premium Bonds jackpot winners in person.
Throughout the pandemic, Agent Million was unable to visit jackpot winners in person for the safety of all involved but has been back on the road since the May 2022 prize draw.
MoneyWeek: What happens if I win £1 million but I'm away on holiday?
NS&I: If a £1 million winner was on holiday when Agent Million visited, they would make contact with the winner via an alternative method.
MoneyWeek: How do you work out which Agent Million contacts the winners each month?
NS&I: All of our Agent Millions perform other roles within NS&I, so which ones are visiting jackpot winners depends on availability. There are, of course, two £1 million winners each month, so two Agent Millions are always in action for each prize draw.
Having five Agent Millions ensures that each month an experienced colleague is on hand to guide our two jackpot winners through a life-changing time.
MoneyWeek: Does the jackpot winner have to prove their identity?
NS&I: For the security of both Agent Million and our jackpot winners, we cannot provide any further information on the process that Agent Million goes through with winners. However, we do ensure that we are paying the prize money to the correct person.
MoneyWeek: What options does the £1 million winner have in terms of how the money is paid to them?
NS&I: The £1 million Premium Bonds jackpot winners can choose to have their prize paid into an NS&I Direct Saver or an account of their choice.
All funds held with us are secure as we are backed by HM Treasury, so if customers choose our Direct Saver account while deciding what to do with their winnings, they have this added peace of mind.
MoneyWeek: Do you help winners who want financial advice?
NS&I: Since April 2022, we have offered £1 million Premium Bonds jackpot winners the option to seek financial advice from any certified financial planner or chartered financial planner in the UK. This means that more than 8,000 advisers have the chance to help winners of the Premium Bonds jackpot. Previously financial advisers came through one firm.
Aside from this, our prize draw team at NS&I keeps in touch with jackpot winners and always recommends they take up our offer to access professional financial advice.
MoneyWeek: What's the average Premium Bonds holding for a jackpot winner?
NS&I: The average holding for a £1 million jackpot winner is £24,649 (based on figures calculated in May 2025). Since the jackpot launched in 1994, there have been more than 500 Premium Bonds millionaires.
In terms of winners who had smaller Premium Bonds holdings, someone from the London borough of Newham won £1 million in July 2004 with a Premium Bonds holding worth £17. The winning bond was purchased in February 1959, so they did have to wait more than 45 years for the win.
