PSTN Switch Off
Prepare for the PSTN switch off
Embrace the future of telephony by replacing your landline with VoIP before the Public Switch Telephone Network (PSTN) is switched off in 2025.
In 2025, the Public Switched Telephone Network (PSTN) is being switched off by BT Openreach, which means everyone, including businesses, currently using PSTN-based services will need to move to another service before then.
The alternative? Voice over Internet Protocol (VoIP), a solution that transmits voice calls and data using an internet connection.
This is a major step towards the United Kingdom’s mass IP-network migration, with VoIP core networks set to replace all the legacy PSTN services in just a few years’ time.

Keep track of the UK’s march to All IP
In parallel to switching off the PSTN network, Openreach are rolling out their fibre broadband network.
To expedite the transition between networks, they have identified and published a list of Priority Exchanges throughout the British Isles where they will be focussing their efforts to get FTTP (Fibre-to-the-Premises) rolled out. When FTTP is available to more than 75% of properties within the catchment of an exchange then they will move to Stop Sell with WLR products, meaning everyone (business and consumer) will need to move to an IP service for new orders.
The current list of Priority Exchanges and their intended Stop Sell dates are shown in the map below (dates correct at time of publication).
How do I use this Priority Exchange Switch Off Map?

Openreach has announced 297 priority exchanges for stop sell of PSTN services by April 2022. You can track which exchanges are switching off, and when via our map
- This map is built on Google Maps, and so can be navigated as you would use any online map
- The priority exchanges have been categorised into 4 “tranches” which go in order of “stop sell” dates – these can be viewed on the left-hand side of the map
- Each Exchange has detailed information including exchange code, postcode, SI number, stop sell date, and helpful FAQ’s.
