Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what discussions his Department has had with mobile network operators on the (a) resilience and (b) reliability of mobile infrastructure to deliver emergency alerts during (i) power outages and (ii) network congestion.

The Emergency Alerts capability is reliant on mobile network operators’ infrastructure to issue alerts. Under the Communications Act 2003 and Telecommunications (Security) Act 2021, UK communications providers have a statutory requirement to take appropriate and proportionate steps to identify risks to their resilience, reduce those risks, prepare for compromises and mitigate and remedy them when they do occur. These requirements are overseen by Ofcom. The Department has regular discussions with the UK’s mobile network operators and works in partnership with communications providers to ensure that their networks remain secure, resilient, and accessible, including during emergencies.
