Is Your Building Ready for the Digital Switch?
With the UK’s traditional analogue telephone network being retired, businesses, facilities managers, and building owners must ensure essential communication systems are ready for the PSTN switch-off in January 2027.
The change affects far more than basic desk landlines. Emergency lift phones, fire alarm diallers, intercoms, access control systems, and security gates often rely on the legacy PSTN network.
If your property still relies on equipment connected to an analogue telephone line, now is the time to audit your system. Delaying your upgrade until the deadline risks severe operational disruption, service downtime, and potential compliance issues.
What is the UK Analogue Switch-Off?
The UK’s Public Switched Telephone Network (PSTN) is being retired as major telecommunications providers transition to modern IP-based digital communications.
While the official national switch-off deadline is January 2027, local exchanges across the UK are already turning off analogue lines under current telecom industry guidance. Equipment relying on traditional copper telephone wiring will eventually cease communicating unless upgraded or migrated to an alternative digital network.
For building managers, it is vital to look beyond standard office telephones and audit all embedded hardware—especially emergency communication devices.
Which Building Systems Could Be Affected?
Any building technology using traditional phone connectivity to send or receive data or voice calls may be impacted. Key systems include:
-
Lift emergency telephone and autodialler systems
-
Fire alarm communication panels and diallers
-
Building intercoms and door entry systems
-
Electronic access control platforms
-
Automated gate and barrier entry units
-
Lone worker and emergency call points
Important: For lift operations, maintaining a continuous, reliable emergency line is a statutory safety requirement under UK legislation. Assuming an existing analogue lift phone will keep working after the PSTN switch-off leaves building owners exposed to legal and financial risk.
Why the PSTN Switch-Off Threatens Lift Emergency Phones in the UK
Lift autodiallers are designed to connect trapped passengers directly to an emergency monitoring service or rescue team.
An analogue-to-digital assessment determines what line type your lift autodialler currently uses and whether an immediate hardware update is required.
Upgrading does not mean replacing the entire lift system or altering the cabin interior. A modern analogue-to-digital converter or GSM lift autodialler gateway provides seamless digital connectivity while leaving your existing lift installation untouched.
How to Check If Your Systems Use Analogue Connectivity
When assessing your building’s communications, you will generally encounter three primary connection types:
-
Analogue (PSTN): Traditional copper wire technology currently being phased out across the UK.
-
Digital / VoIP: Voice and data delivered over an IP broadband connection.
-
GSM / Cellular: A mobile SIM-based solution operating over cellular networks (3G/4G/5G).
If you are unsure which technology your emergency phones or security systems use, a professional site inspection can quickly clarify your setup. Alternatively, you can send equipment photographs directly to our engineering specialists for an immediate evaluation.
Why You Shouldn’t Wait Until December 2026
While 2027 seems distant, waiting until the final deadline creates severe operational risks. As thousands of commercial and residential properties rush to upgrade simultaneously, national demand for cellular hardware and qualified field engineers will spike.
Planning your migration early allows you to:
-
Accurately catalogue all affected building devices
-
Compare cost-effective digital upgrade pathways
-
Spread capital expenditure across your budget cycle
-
Schedule engineer visits to avoid tenant disruption
-
Prevent emergency service outages or non-compliance penalties

Frequently Asked Questions (PSTN Switch-Off)
What happens if my lift phone is still analogue after the PSTN switch-off?
If your lift emergency phone relies on an analogue line after the switch-off, it will fail to dial out during an emergency. This can result in trapped passengers being unable to call for help and may leave building owners in breach of UK safety regulations (such as EN 81-28).
Do I need to replace my whole lift to prepare for the switch-off?
No. In most cases, you only need to upgrade the communication hardware. Installing a GSM autodialler gateway or analogue-to-digital converter allows your existing lift phone hardware to operate over mobile or IP networks without replacing the lift itself.
Who is responsible for upgrading building emergency phones in the UK?
The duty holder, property owner, or appointed facilities manager is legally responsible for ensuring emergency equipment, including lift communication lines, remains operational and compliant.
