National Savings & Investments (NS&I), the UK’s government-backed savings giant, is facing a growing crisis after complaints surged by over 120% in just three years. What was once seen as one of the safest places to store money is now under fire for payout delays, missing funds, and serious failures in handling bereavement cases.
Data from the Financial Ombudsman Service shows complaints jumped from around 73,000 in late 2021 to nearly 160,000 in early 2024. This sharp rise has triggered concerns that the institution, which manages more than £100 billion for 26 million customers, is struggling with operational failures at scale.
For many families, the issue is not just inconvenience—it has led to real financial loss, emotional stress, and in some cases, years of legal battles to recover money that should have been easily accessible.
Why NS&I complaints are rising fast
The biggest source of complaints comes from bereaved families trying to access savings after the death of a loved one. Instead of a smooth process, many have reported long delays, missing account records, and repeated administrative errors.
Families have accused NS&I of:
- Delaying payouts for months or even years
- Losing track of savings accounts and investments
- Withholding Premium Bond prizes
- Providing incorrect information through call centres
- Sending letters addressed to deceased customers
In one shocking case, a widower was denied access to his late wife’s Premium Bonds because NS&I failed to properly log his notification call. Despite informing the bank in time, the system did not record it—leading to withheld prize money until the ombudsman intervened.
Another family faced an even more costly situation. NS&I reportedly lost track of two accounts linked to an estate, forcing a three-year investigation. The delay added around £20,000 in legal costs and caused an incorrect estate valuation, resulting in an extra £2,700 inheritance tax bill.
Financial damage goes beyond delays
These failures have had serious financial consequences. Some families lost thousands in interest because funds were not released on time. Others missed major life opportunities, including home purchases, due to cash being locked in unresolved accounts.
In some cases, incorrect information from NS&I call handlers even led to customers being fined by HMRC. This has raised serious questions about the reliability of customer support systems within the organisation.
The Financial Ombudsman Service has repeatedly ruled in favour of affected customers, forcing NS&I to compensate families. While most payouts are small, complex cases have resulted in significantly higher compensation amounts.
Premium Bonds controversy deepens crisis
One of the most controversial issues involves Premium Bond prizes. Reports suggest that NS&I retains prize winnings if they are paid into accounts where the holder has been deceased for more than a year.
For many families, this has created confusion and frustration, especially when they believe winnings should have been included in estate calculations. Given the popularity of Premium Bonds across the UK, this issue has amplified public attention and concern.
More details about Premium Bonds and customer processes can be found on the official NS&I website.
£3 Billion digital failure behind the chaos
At the centre of the crisis is NS&I’s troubled digital transformation programme, known as Project Rainbow. Initially expected to cost around £1.3 billion, the project has ballooned into a £3 billion overhaul—and has been widely criticised as a failure.
The UK’s Public Accounts Committee described the programme as a “full-spectrum disaster,” highlighting delays, rising costs, and poor execution. Reports suggest NS&I spent around £43 million on consultants alone, yet still failed to deliver a smooth transition.
The disruption caused by this transformation is believed to be a key factor behind missing records, slow case handling, and rising complaint volumes.
Political backlash and public scrutiny
The crisis has also drawn political attention. Critics have blamed NS&I’s leadership for poor performance and failing to modernise systems effectively.
Officials have pointed out that private banks handle similar services daily without such widespread issues, raising questions about efficiency within a government-run institution.
NS&I has defended itself by citing Covid-related disruption and the challenges of outsourcing operations overseas. However, these explanations have done little to calm public anger.
Customers seeking escalation or compensation can approach the Financial Ombudsman Service, which has already ruled against NS&I in multiple cases.
Compensation risk could hit taxpayers
With complaint numbers rising and more cases being upheld, NS&I could face a compensation bill running into hundreds of millions of pounds. Because the institution is government-backed, any large-scale payouts would ultimately be funded by taxpayers.
This turns the issue into a broader economic concern, not just a customer service failure. If trust continues to erode, it could also impact how savers view government-backed financial products in the future.
What this means for savers
For now, NS&I products remain secure in terms of capital protection. However, the crisis highlights the importance of service reliability—especially during sensitive situations like bereavement.
Savers may begin to reconsider where they hold their money, weighing not just safety but also accessibility, customer support, and efficiency.
The institution has issued an apology, acknowledging that some customers did not receive the level of service expected. But restoring trust will require more than words—it will depend on fixing the systems that led to this crisis in the first place.
Bottom line
A 120% surge in complaints, combined with payout delays, lost investments, and a failed £3 billion digital overhaul, has pushed NS&I into one of its biggest crises in recent years. For millions of savers, the story is a reminder that even the safest financial institutions can face serious operational risks.
Whether NS&I can recover from this reputational damage will depend on how quickly it resolves customer issues and prevents further failures. Until then, confidence in one of Britain’s most trusted savings brands remains under pressure.
