The DWP’s objective was to procure a security service allowing for a potential reduction in the number of sites from 900 to around 700, and so is flexible and supports the DWP’s transformation programme plan over the next two years. The DWP transformation programme aims to reduce costs whilst maintaining safety of the users of its properties. We have modernised the way in which security is provided using an Effects-Based Methodology, which has been aligned with the Centre for the Protection of National Infrastructure (CPNI) best practice. Essentially we are looking to minimise threats by reducing and better managing anxiety of members of the public at DWP sites, reducing the likelihood of incidents occurring.
