NS&I (National Savings and Investments) is one of the largest savings organisations in the UK, with almost 27 million customers and over £94 billion invested. We are best known for Premium Bonds, held by over 23 million people, but also offer a range of other savings and investments to suit different people’s needs. NS&I is an Executive Agency of the Chancellor of the Exchequer.
NS&I has been running the non-transactional part of its website on Drupal since March 2010. This was a port of an existing design, to seamlessly replace a proprietary CMS. Meanwhile, work proceeds on a Drupal-based redesign. NS&I's technology partner, Siemens Information Systems, contracted web agency Web Spiders to implement Drupal. The website currently attracts around 8 million page views every month.
