Getting your construction business ready for the PSTN switch-off

Construction sites are often located in remote or challenging environments – off-grid locations, hard-to-access areas, or sites with poor cellular coverage. During the build process, these sites rely heavily on traditional communication systems to manage everything from site access and security alarms to safety management and data protection.  

But a massive change is coming in UK telecommunications: the PSTN (Public Switched Telephone Network) switch-off– the planned removal of traditional landlines, ISDN, and analogue lines – scheduled for January 2027. This change could significantly impact your construction operations if you are not prepared. 

Why the PSTN switch-off matters to construction businesses 

The PSTN switch-off means that all traditional phone lines and related services will be gradually phased out in favour of fibre-based, all-IP communication systems. For many construction sites, this development presents unique complications:  

  • Many sites operate off-grid, relying on legacy communication systems that may not be compatible with new IP-based services. 
  • Site access controls, security alarms, CCTV, and building management systems may depend on traditional lines that won’t be supported after 2027. 
  • Limited digital skills among staff can hinder a smooth migration. 
  • Concerns around data protection and cyber security are more important than ever when moving to new, internet-based systems. 

How the PSTN switch-off affects construction sites 

Here are some potential consequences for your construction business resulting from the UK PSTN switch-off:  

  • Site security and access management: Dependence on analogue lines for alarms, surveillance, and entry systems could leave sites vulnerable if systems aren’t upgraded. 
  • Remote site connectivity: Lack of reliable internet or digital communication options in inaccessible locations can lead to delays, safety risks, and lost productivity.  
  • Data and cyber security: Transitioning to IP-based systems means protecting sensitive site data, preventing cyber threats, and ensuring compliance with security standards.  
  • Operational management: Without modern digital systems, managing logistics, deliveries, and onsite communication becomes more difficult and less efficient.  
  • Limited digital skills: Staff unfamiliar with new technology could struggle to adapt to the changes, risking performance gaps and delays.  

How construction businesses can prepare for the PSTN switch-off 

The key to a smooth transition is partnering with a trusted, experienced telecom provider who understands construction-specific needs and can guide you every step of the way – without you needing to be a tech expert. A good provider will: 

  • Conduct a site communication audit of all your systems that rely on legacy landlines, ISDN, or analogue lines, including alarms, CCTV, access controls, and work management systems. 
  • Explore modern, compatible solutions that will be suitable for isolated locations and complex surroundings. 
  • Plan your migration in phases and develop a clear PSTN migration timetable to avoid delays, security gaps and compliance issues.  
  • Ensure your team understands the new systems, data protection, and cyber security best practices. 

Choosing a PSTN switch-off provider 

Choose a PSTN switch-off provider that has significant expertise and experience. One that has worked with an extensive number of customers in the construction industry, and who understands the specific challenges. They will deliver a smooth PSTN migration, and help you avoid disruption, additional costs, and regulatory concerns.  

Why act early with the PSTN switch-off?  

Waiting until the January 2027 deadline risks service outages, security lapses, and project delays. Acting now allows your construction business to keep operating securely and ensures compliance, and it also gives you a chance to future-proof your digital communication systems.

There's more to the PSTN switch-off than meets the eye

What is the PSTN switch-off? The impending PSTN (Public Switched Telephone Network) switch-off isn’t just about replacing traditional lines. It’s a seismic shift that impacts far more than most realise – and if you’re not prepared, it could cost your business dearly. Most companies are aware that traditional analogue lines and ISDN systems for calls and broadband are being phased out by January 2027. But what many don’t see is the vast ripple effect of this transition – touching everything from lifts to life-critical systems, cash machines, and even traffic lights. What does the PSTN switch-off mean in simple terms? When it comes to the PSTN switch-off, it’s easy to think that it is just about phone lines. But the truth is, it’s much more complex. Here is what’s at stake: Life-saving systems: fire alarms, major medical and safety devices, emergency alarms in care homes, emergency pendants, telemetry services monitoring boiler rooms, dams, sluice gates, and substations. Public infrastructure: traffic lights, bus stops, speed cameras, and traffic management systems. Business-critical devices: PDQ and payment terminals, ATMS, CCTV, video surveillance, door entry, security systems, and remote access points. Transport & emergency services: roadside AA/RAC recovery alerts and devices, and emergency phone lines in hazardous environments. Telecommunications & internet: leased lines, private networking facilities, dial-up lines, broadband DSL services, and international leased lines. Community & public services: emergency teams and vehicles, payphones, modems, industrial control, public alerts, and more. If every one of these vital systems suddenly loses connectivity – chaos, downtime, and danger could follow. The possible business impact of the PSTN switch-off could be financial losses, public safety risks and erosion of customer trust. The PSTN switch-off is a vital business resilience issue – the time to act is now Unlike many providers who may focus on the obvious, we see what others miss. Our team dives beneath the surface, examining your entire network ecosystem to identify what’s at risk when the PSTN switches off.
