Yes, landlines across the UK are being withdrawn as part of the national analogue phone line switch off, with the copper network retiring by January 2027.
For decades, businesses have relied on Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) lines delivered through standard wall sockets. Digital networks are now replacing that infrastructure, so services delivered over copper will no longer operate in their current form.
Identifying which parts of your phone and broadband setup still rely on analogue lines allows you to plan your next steps with clarity.
This industry-wide transition is often described as the PSTN switch-off 2027 or the ISDN switch-off in the UK, depending on the service in use.
The analogue landline network was designed decades ago. Now, as data demands have increased, maintaining separate copper systems alongside fibre networks has become less practical. Ofcom confirms that providers are moving landline services to digital voice technology delivered over broadband [1].
The shift also supports the government’s wider fibre rollout. GOV.UK’s Project Gigabit explains that the programme is designed to extend gigabit-capable connections to hard-to-reach homes and businesses, including areas not covered by suppliers’ existing plans. It also states that the government expects 99% of premises to have access to a gigabit-capable connection by 2032 [2].
For businesses, the implication is fairly straightforward. If you rely on copper-based phone lines or older broadband, you need to have a plan in place before January 2027 so your service continues without interruption.
The analogue switch-off in 2027 affects voice and broadband services delivered over copper infrastructure. This includes PSTN and ISDN lines, as well as broadband services. For example, Asymmetric Digital Subscriber Line (ADSL) and some Fibre to the Cabinet (FTTC) connections.
If your systems rely on a traditional wall socket connected to the copper network, they may need to be upgraded.
Commonly affected services include:
Many organisations are unaware that some of these systems still depend on analogue connectivity. A short review will clarify what needs attention before the switch-off completes.
If analogue services remain in place when the network is withdrawn, some systems may stop operating as expected. This could affect payment processing, monitored alarms, internal communications or broadband connectivity.
Ofcom advises businesses to stay informed about service changes and understand their contractual position when switching providers. Clear communication with your provider ensures you understand what will happen to your service and any associated charges [3].
This matters in the lead-up to the analogue phone line switch-off because late changes leave less time to plan, test, and protect critical services. A controlled migration via our business IT support services gives you more choice and helps reduce avoidable downtime.
When the analogue phone line switch-off is complete, landline calls will be carried over broadband instead of the copper network. The BBC reports that the UK’s switch from analogue to digital landlines is due to be completed by January 2027, and it highlights concerns about reliability in areas where broadband or power cuts are more common [4].
For businesses, this means moving to cloud or VoIP systems that route calls over your internet connection rather than a copper line. It allows flexible call handling, easier management and support for hybrid working. These platforms support call routing, remote access and centralised management across multiple sites.
Alongside this, many organisations will need to review their broadband. Full fibre connectivity offers improved reliability and higher capacity compared with older copper-based services.
Preparing for the analogue broadband switch-off starts with a clear review of your current setup. Many businesses are unsure whether they still rely on PSTN, ISDN or part-analogue infrastructure.
A structured review should cover:
Once identified, services can be upgraded in stages rather than all at once. A phased approach gives greater operational stability and budget control.
The analogue phone line switch-off is a national change that can affect phone systems, broadband, and connected services in different ways. Every organisation’s communication setup is different. Some will need a full upgrade, while others require targeted adjustments.
Town & Country Communications assesses which services are affected and outlines practical upgrade options with clear timelines and cost visibility. As a long-established provider supporting businesses across Dorset and the South of England, we focus on straightforward guidance and responsive support.
