Attempt to modernise NS&I has been a ‘full-spectrum disaster’, MPs find | Banks and building societies

A modernization effort at NS&I (National Savings & Investments), a Treasury-backed savings organization, has been deemed a “full-spectrum disaster” by a parliamentary spending watchdog. The program, initially intended to reduce costs and update operations, has faced significant challenges and escalating expenses.

Project Rainbow’s Troubled Path

Launched in 2020 as Project Rainbow, the transformation aimed to modernize NS&I’s infrastructure, including replacing its long-term IT provider, Atos, with multiple smaller contracts. However, the project’s costs have more than doubled, surging from an initial £1.3bn to £3bn, with limited demonstrable progress to date, according to the Public Accounts Committee (PAC).

Financial Strain and Potential Reversal

The escalating costs have prompted the Treasury to approve an additional £109m in funding, pending parliamentary approval. NS&I now anticipates potentially needing to extend its contract with Atos – the company it originally sought to replace – until 2031, despite Atos experiencing financial difficulties in 2024.

Did You Know? NS&I, established in 1861, holds over £240bn for approximately 25 million customers.

Risks and Concerns

The PAC report highlights “extremely high risk” associated with replacing NS&I’s core banking engine, given the sensitive customer data involved. Crucially, this core work has not yet begun, and NS&I leadership reportedly lacked a detailed plan for managing the complex process. The committee also found that NS&I leaders underestimated the program’s complexity and were overly optimistic about completing it by March 2024.

Expert Insight: The significant cost overruns and lack of clear planning suggest a fundamental miscalculation of the scope and challenges inherent in modernizing a large, established financial institution like NS&I. This situation underscores the risks associated with ambitious IT transformations, particularly when dealing with critical infrastructure and substantial customer data.

Reliance on Consultants

The modernization program has also involved substantial spending on external consultants, totaling £43m. The PAC report indicates that NS&I lacked both an agreed-upon integrated plan and the necessary internal expertise to effectively manage the transformation.

What Could Happen Next

If NS&I fails to develop a realistic and detailed plan for its transformation, further funding could be wasted. The organization may be forced to continue relying on Atos for an extended period, potentially limiting its ability to achieve its original goals of cost reduction and modernization. A possible next step could involve a thorough reassessment of the program’s scope and objectives, coupled with a more conservative timeline and budget.
