The Treasury-backed savings provider NS&I is poised to begin contacting the estates of deceased customers next week, preparing to disburse hundreds of millions of pounds. This follows admissions that past failures by the organisation meant bereaved families were missing out on savings pots.NS&I, which describes itself as the UK government savings bank and offers Premium Bonds, will reach out to all affected estates with holdings of £10 or more to reunite them with the full value of funds.In March, NS&I estimated around 37,500 bereavement claims, totalling £476 million, may have been affected. On Tuesday, the organisation confirmed that as its review has progressed, this figure has since reduced and is likely to fall further.Affected holdings will be adjusted upwards to include either the higher of the interest accrued since the error occurred, or the Bank of England base rate plus one percentage point, in line with Financial Ombudsman Service (FOS) principles, NS&I said.It added that support measures for affected estates also include “a full inheritance tax exemption for the holdings of the remediation population affected by the NS&I tracing error which are returned to the estates to which they rightly belong.”NS&I will reach out to all affected estates with holdings of £10 or more to reunite them with the full value of funds.

Beginning the process of repaying these funds is a key step in putting things right.“We need to ensure that everybody who makes a bereavement claim with NS&I is treated sympathetically and has their case processed as quickly as possible.“Today, this process is taking longer than it should. We have brought in additional staff to get the service back on track.”NS&I, which holds more than £240 billion in customer deposits, said the error happened because the search process used when handling a bereavement claim failed to identify all NS&I products.It said the issue has been resolved for current and new bereavement claims and a new more robust process was introduced in January 2026.NS&I also said that the new process takes longer than before and has resulted in delays for current and new claims.It apologised to those affected by these delays and said it has brought in 100 extra staff to support this work and ensure it returns to processing bereavement claims within usual service standards by autumn 2026.Sarah Coles, head of personal finance at AJ Bell, said: “NS&I is hoping to bring down the curtain on its notorious bereavement drama, by reuniting the estates of deceased customers with the money it failed to track down – with interest.“The Government has agreed to waive any inheritance tax that would have been due on the money, or any income tax on the interest.”She added: “Anyone who has had to deal with an estate is no stranger to delays. Executors have to stick to strict deadlines, and for estates where inheritance tax is due, money has to be handed over within six months of the end of the month in which the person died.“It means any delays in the process can be expensive as well as frustrating.“
