Official guide to recovering dormant assets and navigating estate administration for Premium Bonds.
Official recovery protocols for dormant accounts below.The "Lost" Capital Crisis
As of the 2026 fiscal year, over £80 million in Premium Bonds prizes remains unclaimed. This capital, often referred to as "dormant assets," represents a significant oversight in many personal wealth portfolios. These funds are fully backed by the Treasury and retain their tax-free status indefinitely, yet they generate zero compounding value while sitting uncollected. The primary causes for this disconnection are relocation without address updates and the complexities of estate administration following a bereavement.

Probate & Estate Recovery
A critical component of inheritance tax planning and estate management involves the recovery of Premium Bonds held by deceased relatives. Contrary to common belief, these assets do not expire upon death.
The 12-Month Rule: The bonds of a deceased holder remain eligible for prize draws for 12 months following the date of death. This allows the estate to potentially benefit from a final year of tax-free yields before the capital must be withdrawn or transferred. Executors are advised to contact NS&I immediately to register the death and ensure any prizes won during this period are paid to the estate beneficiaries.
Recovery Protocol
- For Movers: If you have moved house in the last 3 years, check your old postcode history. Many prizes are sent as warrants (cheques) to old addresses and returned undelivered.
- For Executors: You will need the Grant of Probate or Letters of Administration to claim funds over a certain threshold. Small estates may use the 'Small Estates' procedure for faster liquidity access.
Is there a time limit on claiming prizes?
No. There is no statute of limitations on Premium Bonds prizes. Whether the prize was won in 1960 or 2026, the capital obligation remains with the Treasury. It allows for indefinite asset recovery.
Can I search for a deceased relative's bonds?
Yes. NS&I offers a tracing service. You will need to provide the name, date of birth, and date of death. If you are the legal executor, you can consolidate these findings into the estate's total asset value.
How are recovered funds paid?
Once verified, funds are typically transferred via BACS directly to the claimant's bank account. This restores liquidity and allows the capital to be reinvested into other vehicles like ISAs or Pensions.
