The Public Switched Telephone Network (PSTN) will stop working in January 2027. To make this change happen, all old UK phone and broadband connections need to be upgraded to fully digital, fiber-based services that use IP technology. Connect In Cloud is an expert at handling this important move, making sure that your business makes the transition smoothly and is ready for the future of communication.
The PSTN switch-off means getting rid of the Public Switched Telephone Network (PSTN) and replacing it with a much stronger full-fibre network that can handle today’s communication needs.
Openreach is in charge of upgrading phone exchanges all over the UK so that they can use this new network. This upgrade’s goal is to make connections faster, more reliable, and less expensive.
Once the PSTN is fully switched off, all traditional lines that rely on it will become fully obsolete. These include:
All traditional PSTN lines, such as analogue or digital phone lines.
ISDN phone systems used by businesses.
Older internet connections, such as ADSL and FTTC broadband.
To prepare for this change, businesses must upgrade their telecoms and connectivity to ensure they stay in touch and are ready for an all-digital future.
The Public Switched Telephone Network (PSTN) will close in January 2027, which means that all UK businesses must switch to a fully digital, fiber-based network. The first big event, the national “stop sell,” started on September 5, 2023. It stopped the sale of traditional phone lines and FTTC broadband and put a stop to changes to old phone lines.
This migration covers everything. It affects not only basic phone service but also current broadband connections and important devices that use the PSTN network, such as alarms, EPOS machines, door entry systems, and CCTV. Connect In Cloud has the expert plan you need to upgrade all of your affected systems before the deadline.
The Public Switched Telephone Network (PSTN), which is made of copper, has been around since the late 1800s. It is now very fragile and expensive to keep up. It is functionally obsolete because it doesn’t meet the UK’s growing digital needs for higher speeds and bandwidth.
The PSTN needs to be replaced because speed, accessibility, and reliability are now the most important things. Connect In Cloud helps you move to a modern network that is built on strong digital technology, fibre, and internet connectivity.
The Public Switched Telephone Network (PSTN) will be shut down by Openreach in 2027. Every UK business that currently uses PSTN-based services must switch to a fiber-based network before the deadline.
Openreach is on track to finish replacing the old copper infrastructure by 2027. Many exchange areas no longer have copper-based PSTN services for sale because migration is already well underway. Connect In Cloud will handle your upgrade process quickly and make sure you stay connected.
Reports say that about 2.4 million businesses in the UK still use old phone lines and ISDN networks. As the mandatory PSTN switch-off date gets closer, depending on these systems becomes a big risk because they will stop working.
Connect In Cloud suggests using this time of change to switch from ISDN/PSTN services to fiber-based technology. This will make sure that your connection is safe and will last for a long time. Read our full article below to learn about the surprising effects on your connectivity.
The last PSTN switch-off will happen in 2027, but the first “stop sell” deadline for all landlines passed in September 2023. If you still use a PSTN service, you will have to switch to IP (VoIP) phone service and fibre broadband.
Connect In Cloud says you should upgrade your systems and services right away. This makes the transition more organised, so you can get the benefits of hosted telephony and fibre connectivity before your competitors do, while also making sure your business is safe for the future.

The Public Switch Telephone Network (PSTN) is due to be disconnected by Openreach on 31st of January 2027. As a result of this every phone line for UK businesses will move to a fully digital network that operates using voice over internet protocol technology (VoIP) that operates over a fibre-based service. The PSTN switch off will not only effect phone lines across the UK, it will also involve switching broadband lines away from a standard copper line onto a full-fibre network that is being rolled out across the country.
The rollout is gradual across the UK and may mean that you may need to switch from PSTN to fibre and IP services before the January 2027 deadline, it is important to ensure that you switch your services as soon as possible to ensure there is no loss of phone and broadband service as a result.
All traditional PSTN lines, such as analogue or digital phone lines, ISDN phone systems used by businesses, and older internet connections, such as ADSL and FTTC broadband, will all become obsolete. So, if your business is using any of these legacy connections for its phone lines or broadband, it’s time to upgrade to a full fibre connection and a VoIP-based phone system.
Unfortunately, it was announced on the 22nd of May 2024 that the PSTN switch off 2025 was not going to be feasible by BT Openreach. The deadline has since been delayed to January 2027 where all analogue phone lines are set to be deactivated, moving the countries infrastructure to full fibre.
Openreach will close the Public Switched Telephone Network (PSTN), however even with the delay it is still important for all businesses to change over to IP based servers as soon as possible to prevent loss of service when the switch off reaches their premises.
It’s fair to say that the PSTN has served the world of communication well since its introduction back in the late 1800s. However, the copper-based network is old, has become fragile and increasingly difficult to maintain. It’s been straining under the weight of 21st century demands for fast, reliable connectivity and, quite simply, is no longer fit for purpose.

As exchange areas hit 75% completion for installation of fibre connections, “stop sell” notices are being issued on copper-based services. After this point, the services will be withdrawn. Businesses need to upgrade to fibre-based telecoms and internet solutions ahead of this withdrawal process to ensure continuity of service. Look at what services you need to migrate now, avoid a last-minute panic or potentially long-lead times for the installation of new services and take advantage of all the benefits of VoIP services sooner rather than later.
PSTN is a basic service which uses the circuit-switched copper phone lines to transmit analogue voice data. Used for decades in homes and businesses, a PSTN phone number is equivalent to one line and can’t be used for anything else whilst a call is being made. VoIP (Voice over Internet Protocol) uses IP-based technology to make calls over the internet – enabling faster, cheaper, more reliable and flexible communication, whilst also removing the need to rely on expensive and high maintenance copper-based services.
ISDN - Integrated Services Digital Network – allows the digital transmission of voice, video and data over the traditional PSTN phone lines. Put simply, it allows you to make phone calls and access the internet using the same port as your phone line but the departure from the PSTN will also mean an ISDN switch off.
Yes. Openreach is already busy preparing exchanges across the UK and the migration to new, full fibre connections is now well underway. In some exchange areas, a stop sale of legacy PSTN phone lines has already been implemented. You will need to update your legacy telephony and connectivity to a full fibre and hosted solution to ensure your business remains connected before the full Openreach UK WLR switch-off in 2027. *Please note - In some exchange areas, a stop sale of legacy PSTN phone lines has already been implemented & all exchanges will fall into this rule by October 2023.
