Why the landline switch off matters more from now on
Because Openreach has started a stop sell on copper lines, and that changes the timeline for everyone still on an old style landline. You can no longer order or make changes to a standard analogue phone line in most areas. Fibre, or a digital voice service running over it, is now the only option going forward.
The landline switch off itself isn’t new. Providers have been migrating households gradually since it was announced, and the original December 2025 deadline was pushed back once already, to 31 January 2027, specifically over concerns about vulnerable customers being moved before safe alternatives were ready.
What’s new is that the slow, gentle phase is over. The stop sell means the network is now actively pushing people off copper rather than waiting for them to move voluntarily, and the closer we get to January, the fewer engineer slots and porting windows are left for people who’ve put it off.
If you’ve got an ordinary phone line and nothing else depending on it, this is mostly paperwork. If you or someone in your house relies on a telecare alarm, a pendant, or a monitored medical device that plugs into the landline socket, it’s worth five minutes now rather than a scramble in December.
What actually changes when your landline switch off happens?
Your phone service moves from the old copper network to a digital voice service that runs over your broadband connection, sometimes called VoIP. Calls sound the same, numbers usually stay the same, and most households notice nothing beyond a new router or adapter.
The difference that matters is power. A traditional copper landline was powered down the line itself, so it kept working in a power cut. A digital line runs through your router, which needs mains electricity. No power, no dial tone, unless you have a battery back up in place.
That single fact is why telecare and alarm users get special treatment under Ofcom’s rules, and why it’s worth checking your own setup even if you feel broadly on top of things.
Do telecare and alarm users need to do anything before the landline switch off?
Yes. If you, or someone you look after, has a personal alarm, pendant, or monitored medical device connected through the phone line, tell both your telecare provider and your broadband or phone provider before any switch happens, not after.
Providers are required to identify telecare users ahead of migration and offer extra support, which typically includes a free battery back up unit so calls, including emergency ones, keep working through a power cut. Some devices also need a compatible digital alternative fitted by the telecare provider, which can take a little time to arrange.
Our guide to the Priority Services Register covers a related step worth taking at the same time, since it flags you to your utility providers as someone who may need extra support. Ofcom’s own guidance on the landline switchover sets out exactly what providers are required to do for telecare customers, and it’s worth a skim if you’re arranging this for an older relative.
None of this needs to be complicated, and it’s genuinely not your job to know the technical detail. It’s the provider’s job to identify the risk and sort a fix. Your job is just to say the word “telecare” out loud to them before a switch date gets booked.
What should everyone else check before the landline switch off?
Ask your current provider two things: when your area is scheduled to lose copper as part of the landline switch off, and whether you already have a digital voice service running. Many households were migrated months ago without much fuss and don’t need to do anything further.
If you haven’t moved yet, don’t wait for the final weeks. As the deadline approaches, engineer availability and number porting slots tighten, and the people who leave it latest get whatever’s left rather than a choice of dates.
It’s also worth checking anything else that quietly uses the landline: a burglar alarm, a card payment machine, a fax line for an older business setup, or a lift emergency phone in a block of flats. These all need the same conversation with their installer as a telecare pendant does, and they’re easy to forget precisely because they sit in the background until the day they don’t work.
If you’re moving broadband provider at the same time as the landline switch off happens anyway, it’s worth doing both in one go rather than twice. Our guide to switching broadband under One Touch Switch covers how the newer, simpler process works if you haven’t switched under the current rules before.
Key takeaways
- The landline switch off completes on 31 January 2027, and Openreach’s copper stop sell is now active in most areas.
- Digital voice services need mains power, so anyone with a telecare alarm should ask for a battery back up before switching.
- Tell your telecare provider and your phone or broadband provider before migrating, not after.
- Alarms, card machines and lift phones on an old landline all need the same check as a medical pendant.
- Booking now avoids the squeeze on engineer slots expected in the final months before the deadline.
Frequently asked questions about the landline switch off
- Will my phone number change when I move to a digital landline?
- No. In almost all cases your existing number transfers across as part of the switch.
- What happens to my telecare alarm if there’s a power cut?
- A digital line needs mains power to work, which is why providers are required to offer telecare users a free battery back up unit before migration.
- Can I still get a new analogue landline installed?
- In most areas, no. Openreach’s stop sell means new or amended copper line orders are no longer being accepted ahead of the January 2027 deadline.
- Who do I need to tell if I have a medical alarm at home?
- Both your telecare or alarm provider and your broadband or phone provider, ideally before any switch date is booked.
- Is the landline switch off the same as switching broadband provider?
- No. The landline switch off is a network wide change affecting everyone on a copper phone line, separate from choosing to move to a different broadband provider.
- What if I’ve already got fibre broadband?
- You may already be on a digital line without realising, but it’s still worth confirming with your provider that any telecare device connected to your phone socket has been accounted for.
Roo would tell you to sort the boring five minute call now rather than the panicked one in December, and for once he’s not wrong.
