Business Landlines & Phone Lines

What's happening to business landlines in the UK

Openreach is retiring the analogue telephone network (the PSTN) that has carried UK landline calls for decades. New traditional analogue lines have been withdrawn from sale, and the remaining lines are being migrated to digital services, with the withdrawal currently scheduled to complete by 31 January 2027 according to Openreach.

If you've seen a 2025 date mentioned, that's not wrong — it's out of date. The programme was originally due to finish in December 2025 and was pushed back to give vulnerable users and complex lines more time. Both dates still circulate online, which is exactly why so many businesses are confused about where they stand. (Last checked 18 August 2026 — the programme has been rescheduled before, and we track Openreach's announcements so you don't have to.)

The practical upshot: you can't order a traditional analogue business line any more — and any provider telling you otherwise is selling you digital voice and calling it a landline. The question isn't whether your business moves; it's whether the move is planned properly, or discovered when something stops working.

What replaces a landline

Digital voice — your calls carried over a broadband connection instead of copper wires. From the outside, nothing your customers notice changes: they dial the same number, it rings in the office the same way. From the inside, you gain things the old network never did: calls answered on a desk phone or an app, numbers that follow your team anywhere, call routing, voicemail-to-email and proper call reporting.

For most businesses the right destination is a hosted cloud phone system — see our HyperCloud hosted voice service for what that looks like day to day. The landline conversation and the cloud phone conversation are the same conversation in 2026; the only difference is whether you have it before or after the switch-off deadline forces it.

In almost all cases, yes — and this is the fear that stops most businesses acting. UK numbers are moved between providers through a regulated porting process: we place the porting order with your current provider, agree the switch date with you, and plan the cutover so any gap for callers is minimised — typically with calls diverted during the switch itself. A number you've had printed on vans, signage and stationery for twenty years arrives on the new system intact.

A virtual landline gives you a professional business number without a physical line behind it. It behaves exactly like a landline to the people calling it — what's different is where it rings:

• A local geographic number (01/02) for the area you trade in — even without premises there
• 0800 freephone or 03 national numbers for a bigger-than-local presence
• Calls ring your desk phones, an app on your mobile, or both at once
• Add numbers for new locations or campaigns in days, not weeks

For sole traders and new businesses, a virtual landline is usually the whole answer: a proper business number on your existing mobile, without giving your personal number to the world. For established businesses, it's how your number stops being chained to a building.

Since digital voice runs over broadband, the two are no longer separate purchases — the quality of one now determines the quality of the other. Buying them together means one provider, one bill, and nobody blaming the other supplier when something needs fixing.

As part of the line check we'll assess whether your current connectivity will carry your calls comfortably. If it will, we'll say so — you don't need to change broadband to change phone provider. If it won't, we'll quote the bundle honestly, including business-grade connections with the uptime guarantees that phone service deserves.

Modern IP desk phones usually move to the new service and carry on as before. Older analogue handsets can sometimes be kept with adapters, but honestly: once you price the adapters, new handsets designed for the service — or no handsets at all, just the app — are often better value. We'll tell you which applies to your kit rather than defaulting to selling hardware.

If you're running an ageing on-premise phone system (a PBX in a cupboard), the switch-off is the natural moment to retire it — a hosted system does what it did without the maintenance contract, the hardware refreshes or the cupboard.

Analogue lines don't just carry voice. Across the UK they quietly run lift emergency phones, alarm signalling, card terminals, door entry and telecare — and these are the hardest, most-forgotten part of the switch-off. A lift phone that silently stops working isn't an inconvenience; it's a safety and compliance problem. This is the first thing we ask about, because it's the thing most likely to leave a business genuinely stuck:

One honest caveat: for lifts and alarms, the fix usually involves your lift or alarm maintainer as well as us — the phone provider alone often can't sign it off. We coordinate that rather than pretending it's not our problem, and we recommend the specific solution is confirmed with your maintainer, because the compliance detail matters.

Old analogue phones drew their power from the telephone exchange, so they worked when the building didn't. Digital voice doesn't — no power, no router, no calls, by default. For most businesses that's a manageable risk; for some lines it isn't, and the honest answer is to plan for it rather than discover it:

• Battery backup units keep the router and phone running during shorter outages — sized to your kit and how long you need to bridge
• Mobile failover diverts calls to nominated mobiles automatically the moment the line drops
• Safety-critical lines — lift phones especially — get backup power as part of the design, not as an optional extra

The silver lining of the switch-off: once your calls run over broadband, features that were impossible on an analogue line become options. The AI ones are the fastest-moving, and for a small business the useful ones are:

• AI call answering — an AI receptionist that picks up when your team can't, takes messages, answers common questions and routes callers, so calls don't go unanswered after hours or at lunch
• Call and voicemail transcription — calls turned into searchable text, voicemails delivered to your email as readable messages
• AI call summaries — a note of what was discussed and agreed, without anyone typing it up
• Smart call routing — callers directed to the right person or team based on why they're calling, not just who's next in the queue

Some of these are included in the services we quote; some are add-ons, and some are genuinely unnecessary at certain call volumes. We'll tell you which is which for your business — Hypercloud Voice is where the full feature set lives if you want to see what's possible.

Digital lines are priced per user per month, and the move often works out cheaper than what it replaces — analogue line rental and per-minute call charges go away, and the packages we quote include UK call bundles and free calls between your own users and sites. Whether you save overall depends on your current contract, which is exactly what the line check establishes. What moves the price:

• User count — more users, lower per-user rate
• Handsets — reusing what you have, buying new, or renting as part of the monthly fee
• Numbers — extra geographic, 0800 or 03 numbers each carry a small monthly cost
• Bundling broadband — one bill usually beats two suppliers on price, and always on accountability

All pricing is quoted ex-VAT, in writing, with the full monthly figure and contract terms stated before you commit — including what you need to give us (and when) for the migration, because porting has lead times and we'd rather be straight about that at the start than explain it six weeks in.
