NS&I: The UK's Savings Giant Adapting to Digital Finance

Premium Bonds Go Digital: NS&I's Shift to Online and App-Based Management

NS&I launched a mobile app for Premium Bonds in early 2026, allowing 21 million holders to check results, manage holdings, and reinvest prizes directly from their phones. The move marks a decisive shift from paper bonds to a fully digital platform, cutting administrative costs and improving customer experience.

The app includes automated prize reinvestment and instant withdrawals, features that bring NS&I closer to the speed of lottery draws transformed by technology. Similar innovations in prize draw management have set new expectations for user convenience.

NS&I now processes over 90% of new Premium Bond purchases online, up from 60% three years ago, a testament to the shift toward digital-first savings.

• The app eliminated paper bond certificates, replacing them with secure digital records accessible 24/7.
• Users can set up automatic reinvestment of prizes, compounding returns without manual intervention.
• Withdrawals are processed same-day when made before noon, matching the pace of fintech apps like Monzo.
• NS&I reported a 30% reduction in customer service calls since the app launch, freeing resources for complex cases.

This digital transformation positions NS&I to compete with agile fintechs while retaining its core advantage: government backing. The next step is a unified app for all NS&I products, expected by 2027.

NS&I's Bereavement Process: A Step-by-Step Guide for Executors

For families dealing with a death, NS&I offers a structured process to release funds from savings accounts, Premium Bonds, and income bonds. The first step is registering the death within five days in England, Wales, and Northern Ireland, or eight days in Scotland. Executors should order multiple certified copies of the death certificate, as NS&I requires one to process each claim.

Ian Futcher, financial adviser at Quilter, says: “In the immediate aftermath of a death, the priority should be to notify key institutions and secure an overview of the deceased’s financial position.”

• Locate the will and confirm the named executor. NS&I requires a certified copy of the death certificate and the will to release funds.
• Contact NS&I’s dedicated bereavement team, which handles claims for all product types in a single process.
• Provide details of the deceased’s NS&I accounts, including Premium Bonds holder numbers and savings account references.
• NS&I freezes accounts upon notification to prevent fraud, then processes payments to executors within 10 working days of receiving complete documentation.

The process is streamlined compared to commercial banks, but clarity on required documents remains critical. Executors can use NS&I’s online bereavement portal to track progress, a feature added in 2025.

Why NS&I Still Matters in a World of Monzo and Chip

Despite the rise of fintech apps offering high-interest easy-access accounts, NS&I retains a unique position: its products are 100% guaranteed by HM Treasury. No commercial bank or app can match that security, making NS&I the safest place for savings up to any amount. Government backing remains NS&I's core differentiator, especially during economic uncertainty.

NS&I’s easy-access savings account currently pays 4.5% AER, competitive with top-paying banks and significantly higher than the high-street average of 2.8%.

• Green Savings Bond: Launched in 2024, it funds renewable energy projects and pays a fixed rate of 5.2% over three years, appealing to environmentally conscious savers.
• Premium Bonds: Offer a tax-free prize fund with a 4.4% equivalent interest rate, still the UK's most popular savings vehicle with over £120 billion invested.
• Index-linked Savings Certificates: Protect against inflation, with returns linked to RPI plus a fixed margin.
• NS&I’s market share has stabilized at around 15% of UK savings, despite losing ground to fintech in the under-30 demographic.

To compete, NS&I must continue simplifying its app interface and marketing its security guarantee. The organization’s partnership with the green agenda gives it a fresh narrative that resonates with younger savers.

Key Takeaways

• NS&I’s Premium Bonds app modernizes the product with digital features, matching fintech convenience while retaining government backing.
