Question to the Department for Science, Innovation & Technology:

To ask His Majesty's Government, further to the resumption by BT of the rollout of Digital Voice, what assessment they have made of the consultation which has taken place prior to resumption of the Digital Voice rollout.

The UK’s transition from the Public Switched Telecoms Network (PSTN) to IP-based telephony services (such as BT’s Digital Voice programme) is an industry-led migration. While Department for Science, Innovation and Technology (DSIT) meets regularly with telecom providers to discuss their progress, we do not assess individual companies’ programmes given each provider has their own schedule and plans for the upgrade.

Openreach, as the subsidiary of BT Group responsible for operating and maintaining the digital network, is working closely with other communications providers and industry bodies to collectively work through any migration challenges. In 2018, Openreach conducted a consultation towards communication providers to inform its strategy for the PSTN migration.

Separately, BT’s consumer division has reformed its approach to migrating residential customers. For instance, they have introduced the Digital Voice Advisory Group, an association made up of charities and representative groups that has been advising on the needs of customers most affected by the switch. DSIT meets regularly with both Openreach and BT Consumer counterparts to monitor their progress and discuss particular issues.

Customers with limited broadband connectivity will not be adversely impacted by the PSTN migration. In order to function correctly, Voice over IP requires a minimum stable connection speed of just 0.5 Mbps, and for current landline-only customers it will be possible to order a VoIP landline without purchasing an internet connection.

Furthermore, the PSTN migration does not affect the universal service obligations set in the Electronic Communications (Universal Service) Order 2003 which require the designated providers (namely BT Group and KCOM) to offer telephony services throughout the UK. BT Group and KCOM will still be required to provide access to a range of telephony services.

This government remains committed to extending good quality mobile coverage across the UK. The Shared Rural Network programme will increase 4G mobile coverage to 95% of the UK landmass by the end of 2025, underpinned by licence obligations. Furthermore, through the Wireless Infrastructure Strategy, we have announced a new ambition of nationwide coverage of standalone 5G to all populated areas by 2030.
