Question to the Department for Science, Innovation & Technology:

To ask His Majesty's Government what assessment they have made of any disparity in treatment between landline-only customers and those with broadband packages by BT’s Digital Voice rollout; and whether those with copper broadband will be able to terminate their broadband contract and retain a copper landline for telephone use only.

No assessment of any disparity in treatment has been made. It will not be possible to retain a copper landline for telephone use only. From April 2024 to March 2025, there were over 2,600 major incidents on the Public Switched Telephone Network (PSTN), each affecting 500 or more customers. The decision to upgrade the PSTN has been taken by industry and is a necessity.

The PSTN migration does not affect the universal service obligations in the Electronic Communications Order 2003 which require the designated providers (BT and KCOM) to offer landline-only services throughout the UK. It is therefore possible to order a Voice over Internet Protocol landline without purchasing a general internet connection.
