Question to the Department for Digital, Culture, Media & Sport:

To ask the Secretary of State for Digital, Culture, Media and Sport, what steps her Department has taken to help ensure that in the event of power outages people will still be able to make emergency calls, following the proposed changes to the Public Switched Telephone Network in 2025.

The Public Switched Telephone Network (PSTN) is a privately-owned telecoms network and the decision to upgrade it has been taken by the telecoms industry, not the government. However, the government and Ofcom are working together to ensure consumers and sectors are protected and prepared for the upgrade process.

Ofcom, the independent telecoms regulator, has issued guidance on how telecoms companies can fulfil their regulatory obligation to ensure that their Voice over Internet Protocol (VoIP) customers have access to the emergency services during a power outage. This guidance was prepared following consultation with Ofgem and the industry, looking at data on average power outages among other factors.

This guidance states that providers should have at least one solution available that enables access to emergency organisations for a minimum of one hour in the event of a power outage in the premises, and that the solution should be suitable for customers’ needs and should be offered free of charge to those who are at risk as they are dependent on their landline. Ofcom’s full guidance is available on its website here.
