PSTN switch-off for retail organisations

A groundbreaking change in UK business communications is happening, and it’s heading straight for retail stores like yours! The PSTN (Public Switched Telephone Network) switch-off – the planned phase-out of traditional phone lines – is the most significant technological shift in the UK in three decades. Are you prepared to adapt? Here’s everything retail businesses need to know to stay connected, without disruption to daily operations, and futureproof their organisation. 

What is the PSTN switch-off and why should retailers care?  

Since 2023, BT and other UK telecom providers have been ceasing the sale of legacy communication services like conventional phone lines, ISDN, and analogue lines. But the full PSTN switch-off is scheduled for January 2027 – meaning your landlines, broadband, and connected devices will soon need to migrate to new, digital technology.  

For retail stores and other enterprises, the biggest change in UK telecoms history impacts everything from your EPoS systems and card payment machines to emergency alarms, lifts, door entry systems, and beyond. Many of these critical systems still rely on legacy analogue or ISDN connections, which will be no longer supported.  

And here’s the thing: it’s easy to overlook how many devices depend on old PSTN lines. But disruption to these systems could seriously impact your day-to-day retail operations.  

Why is the PSTN switch-off a critical change for retail organisations?  

  • Traditional PSTN lines and ISDN connections are being phased out, replaced by fibre-based ‘all IP’ technology. 
  • The PSTN switch-off will impact all devices and services depending on analogue or ISDN connectivity – and many retailers rely heavily on these. 
  • From cash registers and payment terminals to emergency systems, reliance on outdated tech leaves your store vulnerable during the UK PSTN switch-off or service outages.  

This is the biggest technological upgrade in retail communications history – and if you don’t prepare, you risk interrupted service, costly downtime, and compliance issues. 

How can retailers prepare for the PSTN transition?  

One of the most important steps you can take is partnering with a trusted, experienced telecom provider who understands the unique needs of retail businesses. The right partner will guide you through every stage of the PSTN migration – without you having to worry about complicated technical details or unexpected outages. 

Why a trusted, experienced provider matters for help with the PSTN switch off 

During this major switch, relying on an expert ensures your retail store remains fully operational, your critical systems stay online, and you’re ahead of the game. A good provider will: 

  • Conduct a thorough local audit of all your systems, alarms, and devices that depend on legacy lines – identifying what needs to change without interrupting your daily business. 
  • Design a tailored migration plan that fits your retail schedule, minimising downtime during busy periods. 
  • Handle all the technical work – from installing fibre connections to configuring new IP-based systems – so you don’t have to lift a finger. 
  • Keep you informed, providing clear communications and guidance throughout the process. 
  • Offer ongoing support and training so your staff are confident in using the new systems. 

How to choose the right partner for the PSTN switch-off 

Look for a provider that has extensive experience working with retail businesses and understands their specific challenges. They should be able to deliver a smooth migration, helping you avoid service interference, unnecessary costs, and compliance issues.
