In brief: Will your personal alarm survive the 2027 landline switch-off? Check whether yours plugs into a phone socket and how to move to a digital SIM system.
The 2027 Landline Switch-Off: Will Your Personal Alarm Still Work?
The UK is going through one of the biggest changes to its communication infrastructure in decades. By 2027, traditional analogue landlines will be permanently switched off and replaced with fully digital systems.
For most people, this may seem like a routine upgrade. However, if you or a loved one relies on a personal alarm, SOS pendant, or telecare system, this change could have serious implications. You can read Ofcom's official guidance here. Many analogue-dependent devices will need to be reviewed to ensure they function as expected once the switchover is complete.
What Is the UK Landline Switch-Off?
The UK's existing copper landline network (PSTN) is being retired and replaced with digital Voice over IP (VoIP) technology. This means calls will now be routed over broadband rather than traditional phone lines. The UK Government has identified telecare users as a priority group needing protection during this transition.
Future-Proofing with Digital Connectivity
Our devices use a multi-network SIM, meaning they automatically connect to the strongest available signal across UK networks such as EE, O2 and Vodafone. Because they rely on 4G mobile networks rather than old copper landlines, these systems are completely immune to the landline switch-off. They provide a more reliable, future-proof alternative for 2026 and beyond.
Why This Matters for Older Personal Alarms
Older systems were built for the landline network. They plug into a phone socket and rely on an analogue signal that may not perform consistently on a digital line. Charities like MS-UK have warned that some alarms may fail to connect correctly after the switch. If your current alarm is more than a few years old or only works inside the home, it is time for a review.
Check What Setup You Need
If you are unsure whether your current alarm will work after the switch-off, it is worth speaking to someone who understands the risks. Hannah can help you compare your current setup against modern digital options.
Modern Personal Alarms: Built for the Future
Today's personal alarms have evolved significantly. Instead of relying on home infrastructure, they use mobile networks and GPS tracking. This allows them to work anywhere in the UK, providing faster and more flexible response options. Learn more about these differences in our Pendant Guide and Smart Watch Guide.
What to Look for in a New System
- Technology Type: Ensure the system is mobile/digital based, not analogue.
- UK-Wide Coverage: Does it work at the shops or only in the living room? See our Living Alone Guide.
- Monitoring Quality: The real value is the response team. Check our TSA Standards Guide.
- Fall Detection: Choose a model that alerts automatically. Read our Fall Detection Guide.
One of the most practical ways to choose the right system is to test it. A 14-day trial allows you to build confidence before committing. If you are ready to explore your options, our 2026 Buying Guide offers a clear comparison.
Final Thought: The 2027 landline switch-off is already in progress. For personal alarm users, it is not something to ignore. The key is to choose a system that is reliable, compatible, and designed for the future. For an answer based on your specific situation, Holden Grange are the people to talk to.
Frequently Asked Questions
No. A 4G personal alarm with its own SIM connects through the mobile network and does not depend on a traditional landline.
Check whether its base unit plugs into a telephone socket and ask the alarm provider to confirm the connection type in writing. Do not assume that an older unit is digital-ready.
Contact both the telephone and alarm providers, confirm compatibility, arrange any required replacement, and complete a live test call before the old service is withdrawn.
It can. Ask how long the device and any router or hub will operate on backup power, and keep an agreed fallback plan for longer outages.
