Recommendation 8

NS&I still lacks an agreed integrated plan, facing further programme delays.

Conclusion
In December 2025, after five years, NS&I still has no agreed and approved integrated plan to indicate a Programme end date and milestones. NS&I has repeatedly failed to deliver such a plan.12 At our session in December 2025, NS&I said its system integrator Capgemini had now developed a draft plan, which showed that the Programme would run beyond March 2028. NS&I is now doing a re-planning exercise to try and compress the work and bring this end date forward. NS&I said it would take advice from David Goldstone on this work.13 NS&I could not tell us how much the plan would need to be adjusted, but claimed this would add months not years, and said it was aiming to finish its replanning by March 2026.14 This would leave just two years to complete the Programme before the Atos contract is due to end in March 2028.15 When pressed for whether it could deliver before the Atos contract ends, NS&I acknowledged it would look at extending the Atos contract, potentially to 2031, which would imply a further delay of 3 years and additional cost from the longer timeframe.16
