The UK Landline Switch-Off: What It Means for Your Business
The UK's traditional phone network (PSTN) is being retired by the end of 2027. If you still rely on a landline — or equipment connected to one — now is the time to plan a simple digital alternative.

What is the PSTN Switch-Off?
For decades, the UK's phone network has relied on copper telephone lines known as the Public Switched Telephone Network (PSTN). BT and other providers are moving everyone to internet-based services, with the old network due to be fully retired by the end of 2027.
If your business still uses traditional landlines, ADSL broadband, alarm systems, card payment terminals, fax machines, or other equipment on a phone line, check whether you'll be affected before migration reaches your area.
How Does It Affect Small Businesses?
For sole traders and small teams, the switch-off isn't only about replacing a phone line — it's about keeping the systems you rely on every day working.
- —Missed customer calls — if your number still depends on the copper network and isn't upgraded, customers may struggle to reach you.
- —Other systems can break — payment terminals, alarms, fax, and ADSL broadband often share the same analogue line.
- —Last-minute upgrades cost more — planning early means more choice and less disruption than rushing near the deadline.
What Should Your Business Do?
Audit what still uses your phone line, confirm options with your providers, and move voice communications to a digital service that works over the internet.
A virtual business number is often the simplest path: no new hardware, works on your existing mobile or browser, and unaffected by the PSTN switch-off.

When is the PSTN switch-off happening?
BT's planned deadline is the end of 2027, but some areas are already being migrated. Don't wait for a letter — check with your provider if you still use analogue lines.
Will my current landline number still work?
In most cases you can keep your number through porting to a digital service. Customers keep dialling the same number; it just no longer depends on the copper network.
Do I need to do anything right now?
You don't need to panic, but preparing early gives you more options and avoids a rushed fix later. Start with a quick audit of phones and line-connected equipment.
Is a virtual number a good replacement for a landline?
Yes. It works over the internet, needs no engineer visit, and adds features like voicemail, call forwarding, and SMS. With Connecton you can use a local, mobile, or freephone number on the phone you already have.
