Ireland’s communications networks are moving away from traditional copper-based services towards modern digital alternatives. For businesses, that change could affect more than the office phone: alarms, payment terminals and other equipment may also depend on legacy phone lines.
As of September 2026, there is no single nationwide switch-off date for Ireland. The transition is expected to happen in stages, so the timing can vary by location and service. The best time to check what your business relies on is before a change is announced in your area.
What is the copper switch-off?
The copper switch-off is the gradual retirement of services that use Ireland’s traditional copper network. These include older landline technologies such as PSTN and ISDN, as well as some broadband services.
As providers move towards fibre and IP-based networks, equipment that depends on copper lines may need to be upgraded or connected in a different way. The exact impact will depend on the services available at your premises and how your systems are configured.
Why is the network changing?
Copper networks have supported homes and businesses for decades, but communications technology and the way organisations work have changed. Digital services can support modern voice, data and collaboration requirements, while providers are investing in newer network infrastructure.
For businesses, the transition is an opportunity to review whether existing phone and connectivity services still meet operational needs—not simply to replace like with like.
What could be affected?
Start by checking any service or device that uses a traditional phone line or dial-up connection. This may include:
- Desk phones and legacy phone systems
- PSTN or ISDN lines
- Alarm and monitoring systems
- Lift emergency phones and door-entry systems
- Card payment terminals and point-of-sale equipment
- Fax machines and other specialist devices
Some systems may be less obvious than a phone plugged into a wall socket. Contact the suppliers responsible for alarms, lifts, payment equipment and building systems to confirm how they connect and what alternatives they support.
How can businesses prepare?
A few practical steps can help you plan a managed transition:
- Make an inventory. List your phone lines, phone system and any equipment that may use them.
- Check what is available at each site. Find out which broadband and voice services can be supplied to your premises.
- Speak with equipment providers. Ask whether alarms, lifts, payment terminals and other connected devices need an upgrade or alternative connection.
- Review your phone system. Consider whether a cloud phone system, VoIP or SIP trunking could suit your requirements.
- Plan continuity. Check power, internet resilience and backup arrangements for essential communications.
- Allow time to test and train. Give your team time to become familiar with any new system before relying on it day to day.
Moving business calls to IP
Voice over Internet Protocol (VoIP) services like IP Telecom's carries calls over an internet connection rather than a traditional copper phone line. Depending on your requirements, an IP-based solution can support features such as calls on desktop and mobile devices, flexible call routing and integration with other business tools.
A reliable voice service also depends on having an internet connection suited to your needs. Before making a change, consider connectivity, expected call volumes, emergency calling, number portability and what should happen if power or internet service is disrupted.
