While the switch-off deadline may seem like a long time away, installers should act now and switch older systems that run on PSTN over to an all-digital Internet Protocol (IP) network to ensure that customers don’t experience service interruption or downtime. Installers who want to navigate the PSTN switch-off effectively should begin preparations as soon as possible.
What risks does the PSTN switch-off create?
Alarms may no longer work
Despite the switch-off fast approaching, many key safety systems still rely on the PSTN for their main signalling connection. This means that failure to make the switch will put a number alarm services, such as fire, intruder, and lift alarms, at risk of no longer working. Additionally, legacy systems may not be fully monitored, meaning customers could be left vulnerable to emergency situations without any prior warning that their system isn’t working if the switch-off occurs before upgrading. With so many technologies at risk, navigating the PSTN switch-off process has become a top priority for many businesses.
Possible legal and financial penalties
The PSTN switch-off means that businesses could also face legal and financial penalties when the network is switched off. For example, an alarm system that stops working due to network shutdown could breach insurance warranties as the system has failed to be maintained properly. Many dual-path systems depend on the PSTN as a backup path, and once the switch-off happens it will become a single path making the system less effective, more vulnerable to breaches and likely to invalidate any insurance that has specified a particular grade or type of system. In this context, companies must carefully navigate PSTN switch-off implications to remain compliant and protected.
Supply shortages closer to the deadline
Supply shortages are another consideration for installers navigating the switch-off. Network shutdowns place a huge pressure on resource, so equipment shortages are much more likely closer to the deadline due to high demand. Delaying the upgrade of legacy systems could increase the risk of being caught in a last-minute rush to source equipment, and also leaves less time to educate customers and troubleshoot issues should they occur after the network shutdown. For those wishing to navigate the PSTN switch-off efficiently, planning ahead is absolutely essential.
Customer resistance to change
Another challenge that installers will face is customer resistance. Many end users don’t realise that their systems are linked to the PSTN, so they may view the upgrade as unnecessary. This lack of awareness puts added pressure on installers, who must help bridge the knowledge gap with clear, confident communication. Support from trusted suppliers, like AddSecure, can make a big difference, helping installers overcome objections and guide customers through the change with ease. Navigating the PSTN switch-off means addressing these concerns directly and providing reassurance at every step.
What should installers do to tackle the PTSN switch-off?
Despite the challenges faced, installers who act now can stay ahead of the PSTN switch-off by taking proactive steps. Do not rely on future extensions to deadlines providing a false sense of security that there will be time later. The most successful approach is to navigate the PSTN switch-off with a clear, step-by-step plan.
Audit all customer systems
Identify which systems rely on PSTN or analogue connections ahead of January 2027, and prioritise upgrades based on urgency and service risk. Installers should also start to plan upgrades alongside scheduled service visits to reduce disruption and minimise repeat site visits. By carefully auditing, you can navigate the PSTN switch-off smoothly and avoid last-minute complications.
Communicate with customers
Education will play a key part in the PSTN switchover. Prepare clear communications and pre-empt potential FAQs to help customers understand why the upgrade is essential, not optional. Speak to your trusted suppliers for support materials to help the process. In addition, communicating openly is a crucial part of helping all stakeholders navigate the PSTN switch-off.
Choose future-proofed upgrades
When updating alarm systems from PSTN, opt for IP-based, mobile-first, or hybrid (IP + 4G) solutions that will last for years to come. Whichever equipment you choose, consider dual-path connectivity for greater resilience. This upgrade strategy can help your business and your customers successfully navigate the PSTN switch-off with confidence.
At AddSecure, we provide alarm signalling solutions that use reliable IoT solutions for monitored alarm transmissions, providing a clear communication path should the system be triggered by a breach. Our AddSecure NPG portfolio includes both fixed IP and Wi-Fi connected models, plus dual SIM and roaming 4G options to ensure a fully future-proofed system that won’t go down when legacy networks switch off. Those seeking solutions can confidently navigate the PSTN switch-off by choosing robust, adaptable products like these.
