Openreach and the wider UK telecoms industry are retiring the old Public Switched Telephone Network (PSTN) and associated copper-based services as part of the move to an all-digital, internet-protocol (IP) based network.
The PSTN and associated wholesale copper services - including traditional analogue phone lines, ISDN2, ISDN30 and other legacy products - are being withdrawn.
These services historically relied on copper wiring connected from exchanges to premises. They will be replaced with digital alternatives such as Full Fibre (FTTP) and IP-based broadband services like SOGEA, SOGFAST and other All-IP products.
Originally planned for December 2025, the final withdrawal of the PSTN network has been rescheduled to 31 January 2027 to give more time for migration, particularly for vulnerable customers and specialist services. By this date, all legacy services that depend on the PSTN must be transitioned off the copper network.
On 16th January 2023 Openreach declared the Seal Exchange, Sevenoaks as a 'FTTP Priority Exchange' as part of their Tranche 11 list of exchanges and issued a 'Stop Sell' notice effective from Friday 16th February 2024
Stop Sell is triggered when a majority (75%) of premises connected to a particular exchange can get ultrafast Full Fibre. Customers who then want to switch, upgrade or re-grade their broadband or phone service will have to take a new digital service over their new Full Fibre network.
