Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what steps he is taking to ensure there will be no disruption to telecare users' service with the end of the Public Switched Telephone Network.

The Government is determined to ensure that any risks arising from the industry-led migration of the Public Switched Telephone Network (PSTN) to Voice over Internet Protocol (VoIP) are mitigated for all customers across the UK.

Communication providers and network operators signed voluntary charters in December 2023 and March 2024, ensuring their commitment to protect vulnerable consumers during the PSTN migration. On 18 November 2024, the major communication providers agreed to adhere to further safeguards in the Non-Voluntary Migrations Checklist. Safeguards include signing data sharing agreements with local authorities to identify telecare users and a commitment to ensuring no disruption to telecare users' service when their landlines are migrated. As of April 2025, over 90% of local authorities have signed a data sharing agreement with at least one communication provider.
