Question to the Department for Science, Innovation & Technology:

To ask His Majesty's Government what steps they are taking to retain copper landlines in rural areas to ensure continuous telephone access during extreme weather events.

The copper landline network, also known as the Public Switched Telephone Network, is a privately-owned network and the decision to upgrade it has been taken by the telecoms industry. The industry’s decision to upgrade the PSTN is due to necessity, as the network is increasingly unreliable and prone to failure. In 2024, Ofcom (the independent telecoms regulator) recorded a 45% increase in PSTN resilience incidents. The PSTN is not being retained anywhere.

In the event of a power cut caused by extreme weather events, telecoms companies have a regulatory obligation to ensure that customers have access to emergency services for a minimum of one hour, for example by providing them with battery back-ups that power telephones during a power outage. In practice, many are offering solutions which exceed these minimum standards.
