What the project is for

The Business Transformation Programme (BTP) exists to modernise NS&I’s technology, operating model and supplier arrangements so that the organisation can continue to deliver safe, secure and reliable savings products while providing long‑term value for money to the taxpayer. The programme is designed to replace ageing, expensive, inflexible legacy systems and move NS&I towards a more cost-effective, resilient, scalable and digital‑first service, enabling it to respond effectively to changing customer needs, Government policy requirements and market conditions. In doing so, the programme aims to: - Reduce the long‑term cost of running the business, including Business‑as‑Usual operations and future change delivery - Improve customer experience and accessibility, supporting digital self‑service while ensuring provision for vulnerable or excluded customers - Increase operational resilience and security, including improved cyber security and continuity of service through transition and beyond - Strengthen NS&I’s agility and change capability, allowing faster, lower‑risk delivery of new products and policy‑driven change for HM Treasury Overall, the Business Transformation Programme underpins NS&I’s ambition to become the UK’s most trusted savings provider, with a sustainable delivery model that supports public services over the long term and aligns with Government Major Projects Portfolio (GMPP) expectations for value, resilience and capability.

Departmental delivery commentary

Delivery confidence is assessed as RED because the programme cannot currently be delivered to agreed cost, schedule and scope without significant re‑planning and re‑baselining. There is no agreed, affordable end‑to‑end delivery plan, with delivery outcomes dependent on the resolution of active options analysis and future funding decisions. Confidence is further constrained by Spending Review affordability pressures, ongoing uncertainty around scope and sequencing, and the absence of a finalised, quantified benefits baseline. Until these issues are resolved and a preferred option is approved, delivery commitments cannot be made with confidence. Senior‑level intervention and agreement with HM Treasury are required to restore a credible baseline and improve delivery confidence.
