Summary Bullets:
• UK PSTN switch-off in December 2025 presents a significant revenue and market share gain opportunity for telecoms service providers.
• BT has started rolling out Digital Voice on a region by region basis and many smaller businesses may not realize how it might affect them.

As mandated by Ofcom and the Government, the UK’s analog network (PSTN) is set to be ‘switched off’ in December 2025, meaning that all fixed connectivity will be carried over IP networks. BT has conducted successful pilots in Salisbury (Wiltshire) and Mildenhall (Suffolk), and now plans to roll the new platform out on a region by region basis, starting with the East Midlands in July 2023, Yorkshire and Humber in August, and other regions going forward until the summer of 2024:

1) Autumn 2023: North West and London
2) Spring 2024: West Midlands, South East; Wales; and East Anglia
3) Summer 2024: North East; Scotland; and South West
