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.

Top 5 benefits of a network intelligence solution

Do you know exactly what’s going on in your network, or is it all a bit of a mystery? If you’re in the dark, it could be costing you more than you think. Without visibility into your network, you can’t stop downtime before it starts. With downtime costing an average of £7000 per minute (1) that’s a high price to pay.

Building resilience in the public sector: a strategic guide

Beyond traditional cyber security: how to create an effective cyber resilience plan In an era where cyber threats are growing in scale and sophistication, public sector organisations must go beyond traditional cyber security. While many may feel like they are too small a target to fall victim to the headline-grabbing attacks we see in the news, it is the unfortunate truth that all organisations are at risk, whether they turn over vast amounts of money or not. Therefore, the ability not only to defend against attacks, but also to recover quickly and continue delivering essential services is of paramount importance.

How can businesses dispose of devices in an environmentally friendly way?

What is WEEE compliance? Electronic waste (e-waste) is one of the fastest growing waste streams today, with the UK generating 1.7 million tonnes* per year. As our reliance on electronic devices such as laptops, desktops, mobiles, and office equipment increases, so does the importance of responsible IT equipment disposal in the UK. When devices become faulty or outdated, the vast majority are simply disposed of, adding to the mounting electronic waste (e-waste) in landfills. This creates even more WEEE (Waste Electrical and Electronic Equipment). Effective responsible IT asset disposal in the UK is crucial to reduce environmental impact and support a sustainable future. With rapid technological advancements, upgrading IT infrastructure, and increasing regulations on WEEE compliance, adopting eco-friendly electronics recycling solutions is more important than ever. If we don’t all start to reduce, reuse, and recycle electronic devices, this is only set to get worse. We all have a role in minimising e-waste in the workplace, supporting the planet, and reducing demand for resource-intensive manufacturing What do companies do with old electronic devices? According to Sue Owens, Head of Supply Chain Services at Wavenet: “There isn’t a single answer to the climate crisis, or how we can recycle our way out of trouble, but responsible electronic device recycling and secure data destruction are essential parts of the solution. We need to look at all methods of recycling. Even the smallest contribution in reducing e-waste in the workplace adds up to be part of the bigger picture.” Recycling old laptops, mobiles, and other IT hardware not only helps manage the rising tide of end-of-life equipment recycling but also ensures compliance with WEEE directives. Proper certified electronic waste disposal providers help companies turn obsolete devices into environmentally safe recyclables or components, reducing the need for raw material extraction. Sue continues: ”The more organisations recycle, the less we need to mine. While the mining industry is a major contributor to planet-warming emissions, it also holds the key to a net-zero future. We don’t need to extract more – we need less. As clean energy and EVs expand, the total amount of materials mined will actually decrease, and we can significantly reduce reliance on coal that still fuels the industry’s revenues. Less mining, more sustainability – that’s the future we must build. To make a difference, it’s up to organisations to recycle whatever we can; however, data destruction is critical to the security of your business. Compliance with the WEEE directive and recycling units back into the market, either as components, or broken down into their elements is a huge contributor.” How do businesses recycle computers and phones?
