Digital Swtich Off – One Year Away
By Justine Maroudias, Director of Talk UK
2026 marks one of the most important transition periods the UK communications industry has seen in decades, as the traditional landline (PSTN) network moves towards its final switch off in January 2027.
As Director of Talk UK, I speak with business owners daily, and one thing is clear: many people still aren’t fully aware of what this change means for them, or how disruptive leaving it too late could be.
Over the last few months, we’ve also heard from multiple industry sources that pricing on legacy landline services is expected to increase throughout 2026. While figures being discussed include rises in spring, summer and autumn, these increases remain unconfirmed.
If they do materialise, many businesses could find themselves paying close to double for ageing services that are approaching end of life.
That’s why, at the start of 2026, now is the right time for businesses to review their setup and get ahead of the transition.
By January 2027, the UK’s entire copper based landline network will be retired. Every traditional phone line, the ones businesses have relied on for decades will stop working and be replaced by fully digital, internet based services.
Industry estimates there are still around three million copper lines in use across the UK that will need upgrading during 2026, many of which support business operations.
Crucially, the switch off affects much more than just desk phones. It also includes:
Multi-line phone systems
Lift lines
Alarm systems
Payment terminals
Door entry systems
Fax lines
Any device connected to a traditional phone socket
If your business relies on any of these, they will need to be upgraded ahead of the final switch off.
From conversations across the telecoms industry, 2026 is expected to be an extremely busy year as businesses begin migrating away from legacy systems. When combined with potential pricing pressure, the risks of waiting are becoming clearer.
Here’s what could happen if you delay:
If reported price increases on legacy services do come into effect in the next few months, businesses that remain on older technology could end up paying significantly more for services that are months away from being withdrawn.
As demand increases closer to the final switch off, migration queues will grow. This can mean longer wait times, limited appointment availability, and an increased risk of downtime.
As capacity tightens, suppliers may limit new migrations. Businesses that act earlier typically have greater choice around systems, pricing, and installation windows.
Even a short period without connectivity can result in missed enquiries, lost bookings, and unhappy customers and lost revenue.
You don’t need to overhaul everything overnight, but you do need a plan. Practical steps every business should take include:
List every phone line and every device connected to it. Many businesses discover they rely on more analogue services than they realised.
VoIP is flexible, cost effective, and works wherever you do. Businesses can keep their existing numbers and benefit from features such as:
Voicemail to email
Call menus
Call routing
Mobile and office integration
Multi-site setups
Failover options
Fax to email
Alarm systems, lift lines, and payment machines often require specific digital alternatives and should not be overlooked.
Digital systems allow businesses to expand, relocate, or change how they work without losing continuity, something older systems simply can’t offer.
2026 will be a high demand year across the industry. Early planning avoids last minute pressure and ensures a smoother transition.

2026 is a landmark transition year for UK communications. While pricing changes may vary, the digital switch off itself is definite, with a final cut off in January 2027,and every business will be affected in some way.
Planning early allows businesses to avoid disruption, manage costs, and stay connected throughout the change.
As Director of Talk UK, my priority is ensuring business owners have the clarity, options, and support they need to navigate this transition with confidence.
