The 2027 Copper Switch-Off: What Your Business Needs to Know
The UK’s 2027 copper switch-off is one of the biggest changes to communication and broadband in decades. The traditional copper-based PSTN (Public Switched Telephone Network) and ISDN lines that many businesses still depend on will be retired. After December 2027, all calls and connectivity will move to digital solutions — mainly fibre broadband and VoIP phone systems.
If your business hasn’t started planning, now is the time. Here’s everything you need to know.
What is the 2027 Switch-Off?
- BT Openreach has announced that the UK’s ageing copper phone network will be switched off by 2027.
- This includes both PSTN and ISDN lines, which have been the backbone of business communications for decades.
- After this date, all services must run over digital connections such as fibre broadband, VoIP (Voice over Internet Protocol), or mobile/4G/5G solutions.
This change is sometimes referred to as the Digital Switchover.
Why Is the Switch-Off Happening?
- Ageing infrastructure – Copper lines are expensive to maintain and can’t keep up with today’s demands.
- Better technology – Fibre broadband and VoIP services provide faster speeds, more features, and greater reliability.
- Future-proofing – Digital networks support advanced services like cloud computing, video conferencing, and remote working.
How Will the 2027 Switch-Off Affect Businesses?
- Landlines will stop working. If your business still uses traditional phone lines, they will no longer function.
- Card machines and alarms may be affected. Many payment terminals, alarms, and fax machines currently rely on analogue lines.
- You’ll need VoIP or digital-ready alternatives. Every call will be made via the internet, requiring new systems.
- Broadband upgrades may be necessary. Fibre connections will replace outdated ADSL or FTTC in many areas.
What Is VoIP and Why Is It Essential?
VoIP (Voice over Internet Protocol) allows phone calls to be made over the internet instead of copper lines. It’s already widely used by businesses, but after 2027 it will be the only option.
Benefits of VoIP for businesses:
- Lower costs – Cheaper than traditional lines.
- Scalability – Add or remove users easily.
- Advanced features – IVR menus, call forwarding, voicemail to email, and mobile apps.
- Work anywhere – Staff can make and receive calls on mobiles or desktops.
- Future-proof – Fully compliant with the digital switchover.
Preparing for the Switch-Off
Here are some steps to take before the deadline:
Audit your current setup
- How many landlines do you use?
- Do you have alarms, lifts, or payment machines linked to copper lines?
Upgrade your broadband
- Check if FTTP (Full Fibre) is available in your area.
- In rural areas, look at 4G/5G broadband or satellite solutions like Starlink.
Move to VoIP
- Transition your phone system early to avoid disruption.
- Consider features that could improve efficiency (IVR, call recording, mobile apps).
Review your contracts
- Avoid signing new long-term PSTN/ISDN contracts.
- Choose providers who are digital-switchover ready.
How Rural Businesses Can Prepare
Many rural areas still struggle with poor connectivity, but the switch-off is happening nationwide. If you run a farm, B&B, workshop, or office in Wales or across the UK, you’ll need a solution.
Options include:
- FTTP broadband (where available).
- 4G/5G broadband with business-grade routers and external antennas.
- Satellite broadband (Starlink or Viasat) for remote locations.
