Atos & NS&I pioneering business transformation


Atos Business Process Services grows our clients’ businesses whilst helping them transform into more digital organisations, equipped to continually meet the disruptive impact of rapid technology innovation and changing consumer expectations.

NS&I is both a government department and an Executive Agency of the Chancellor of the Exchequer, and has been a critical part in raising cost effective financing for the UK government for 150 years. 25 million UK citizens have invested £147 billion in savings products with NS&I.

  • Shifting from a product-centric to a customer centric service, supported by a rationalised and more secure infrastructure.
