## Summary

The Department for Energy Security & Net Zero, located in London, has initiated the planning stage for procuring application management services for the Radiological Response and Emergency Management System (RREMS). This system records and analyses radioactivity levels in the United Kingdom, serving vital functions during civil and defence nuclear emergencies. The procurement falls under the IT services category, specifically consulting, software development, internet, and support. Key dates include a future notice to be issued by 22 March 2026, with the contract period planned from 1 July 2026 to 30 June 2029, and a potential extension until 2031. This planned procurement reflects the department's critical role as a public authority within central government.

This tender provides significant business growth opportunities for firms specialising in IT services, particularly those experienced in handling complex systems involved in national security and emergency response. Companies with a strong track record in consulting, software development, and support services are well-suited to compete. Engaging in this procurement process could enhance a contractor's reputation in delivering high-stake services for government projects, potentially opening doors to further public sector collaboration.
