NS&I failures deepen agony for families chasing premium bonds

Errors and delays at National Savings and Investments (NS&I) have left bereaved relatives struggling to access Premium Bonds and other savings, compounding the practical and emotional burden after a death. Claimants report long waits and burdensome paperwork, notably the requirement for probate in many cases.

Official records and parliamentary statements show NS&I notified the Treasury on 18 December 2025 of an “operational failure” to trace accounts comprehensively. The organisation introduced a more thorough search process in January 2026, which NS&I admits takes longer and has lengthened response times for both historic and new bereavement claims.

Publicly available figures indicate about 34,000 estates could be affected, with missing payments estimated at roughly £367 million. NS&I has said it will proactively contact affected families, that reimbursed amounts will be exempt from inheritance and income tax, and that it has increased staffing to tackle the backlog, aiming to restore normal processing times by autumn 2026.

From a market and saver-protection perspective, the episode risks undermining trust in a widely used, government-backed savings vehicle. NS&I serves some 24 million customers and carries a state guarantee, but operational failures and paper-based procedures — including a £5,000 probate threshold — have exposed practical vulnerabilities for executors and beneficiaries. The issue has drawn scrutiny over NS&I’s long-running digital modernisation programme and record-keeping.

Analysts say the immediate priorities are fair reimbursement, transparent timelines and improved traceability of historic accounts. Parliamentary and audit scrutiny will continue, with expectations that NS&I must publish and deliver a workable remediation plan. For many families the next year will be decisive in whether confidence in Premium Bonds and state savings can be repaired.
