National Savings and Investments (NS&I) is an Executive Agency of the Chancellor of the Exchequer. It is one of the UK's largest retail savings organisations with 25 million customers and more than £202 billion of funds under management, best known for Premium Bonds but also offering a wide range of other savings products. NS&I raises cost-effective financing for the Government, by offering a range of secure retail financial savings products, as an alternative to raising funds on the wholesale market.

NS&I's core services are currently provided by Atos IT Services UK Limited, which manages sales processing and customer servicing, in addition to IT and infrastructure services. This contract will end on 31st March 2024, and NS&I is embarking on a significant programme of transformation for its outsourced services, called the Rainbow Programme.

It focuses on implementing a future integration platform to support upcoming business change, as well as providing Service Operations capabilities to establish a stable state for delivering long-term business objectives. In addition, this package will include the provision of a Central Security Monitoring Service.
