National Savings and Investments (NS&I)

National Savings and Investments is the state-owned savings provider that runs Premium Bonds, Direct Saver, Income Bonds, Investment Accounts, and the historical range of certificates and bonds. NS&I is a non-ministerial government department, separate from any high-street bank, and its bereavement process runs entirely in-house. [source: nsi/what-to-do-when-someone-dies-2026-04-30.html]

NS&I has its own probate threshold and its own claim form, bank thresholds and forms do not apply. Holdings can be claimed by phone or by completing the bereavement claim form on nsandi.com; the claimant provides the deceased's holding numbers (or NS&I will trace them on the deceased's name and address), the death certificate, and proof of executor or next-of-kin status. Premium Bonds remain in the prize draw for 12 calendar months after the date of death; any prizes won during that period are paid to the estate.

NS&I's bereavement number is 08085 007 007 (free from UK landlines and mobiles). Holdings under the in-house threshold are released on a small-estates declaration without a grant of probate; holdings above the threshold require the grant. [source: nsi/what-to-do-when-someone-dies-2026-04-30.html]
