Do Businesses Still Need a Landline in 2026?

Quick answer

Almost no business needs a copper landline. Most still benefit from a fixed number. Those are two different questions, and separating them answers almost everything. The copper is going regardless - the network closes on 31 January 2027. What is genuinely optional is whether you keep a fixed geographic number and proper call handling, and the honest answer there depends on whether more than one person ever needs to answer the same call, and whether your customers judge you before they ring.

I get asked this most often by owners who suspect they are paying for something out of habit. Often they are. But the cheap end of "keeping a landline" is now genuinely cheap - a number that rings a mobile costs very little - so the decision is rarely the money.

Two questions, not one

Almost every confused version of this conversation collapses two separate things:

"Do I need a copper landline?" No. That decision has been made for you: new analogue lines have not been orderable since 2023 and the network closes on 31 January 2027.

"Do I need a fixed business number and proper call handling?" This is the real question, and it has a genuine answer either way depending on your business.

Once you separate them, the anxiety usually goes. Nobody is asking you to defend copper. They are asking whether a number that is not somebody's mobile is worth having - and what it should cost.

What a fixed number actually buys you

Four things, and it is worth being precise rather than sentimental about them.

It is an asset that stays with the business. This is the one owners underrate most. A customer relationship attached to a member of staff's mobile number walks out of the door with that person. A fixed number stays, gets re-pointed at whoever replaced them, and carries on working.

It can be answered by more than one person. A mobile rings one handset held by one human. A fixed number can hunt across a team, queue at busy times, and fall to voicemail-to-email out of hours. This is the functional difference and it is not small.

It signals permanence. An 0161 or 01282 number reads as a business with premises in a way a mobile does not. We are not going to quote you a statistic on this, because the honest position is that it varies enormously by sector - a plumber's mobile number is entirely normal, an accountancy practice's is not. You know your own market.

It is stable. Numbers survive provider changes, office moves, and technology transitions like this one. Printed on a van, a number is a ten-year commitment, and a fixed one is far more likely to survive ten years than a mobile tied to a contract and a person.

When a fixed number earns its place

When mobile-only is genuinely fine

We would rather say this than pretend otherwise, because the alternative is selling people things they do not need.

If you are a one-person business working out of a van, on sites, or in customers' homes; if nobody else ever needs to answer your calls; and if your customers are entirely comfortable ringing a mobile - then a business mobile with a decent voicemail is the whole answer. Adding a fixed number to that setup buys you very little.

Two caveats worth knowing before you commit to it. The first is the asset point above: as soon as the business is worth something to somebody else, a customer base that only knows a personal mobile number is a weakness. The second is growth: the day you take on a second person, the mobile-only setup has to be unpicked, and unpicking it means telling customers to ring a different number - which is the one thing everybody wants to avoid.

The middle ground most people land on

A fixed geographic number that rings a mobile. It costs very little, and it gets you most of the upside with none of the copper.

In practice that means a number on a hosted service, delivered to an app on the phone already in your pocket. Outbound calls present the business number. Inbound calls can be switched off at 6pm and sent to voicemail-to-email. If you take on a second person, they get added to the same number without anything changing for customers. And if you ever sell the business, the number goes with it.

This is where the majority of sole traders who ask us the question end up, and it is the cheapest thing on the menu after doing nothing.

The one clearly wrong answer

Keeping an unused analogue line "just in case".

It fails on every axis. The network it depends on closes on 31 January 2027, so the reassurance is temporary. Legacy line rental rose in stages through 2026, so the standing charge is the highest it has ever been - see the WLR price rises. And it delivers nothing a modern number does not do better.

If a line genuinely exists for a reason - an alarm panel, a lift, a card terminal - that is not "just in case", that is a device that needs a proper replacement arranging with its own supplier. Work through devices that rely on phone lines before you cancel anything.

What it costs either way

The costs here are small enough that they should not drive the decision, which is worth saying plainly.

A fixed number that diverts or rings an app is the cheapest option and is often bundled with something you already buy. A proper hosted seat for someone who answers calls all day costs more but replaces a line rental you were already paying. Mobile-only costs whatever your mobile plan costs, which you are paying anyway.

Set against that, the cost of not having a way for two people to answer the same call is measured in missed enquiries, and it does not appear on any bill. That asymmetry is why I rarely see a business regret keeping a fixed number, and regularly see one regret handing out a personal mobile. Our business phone line cost guide has the detail.

So what should you do?

1. Decide whether more than one person ever needs to answer. If yes, you want a fixed number and proper routing. Stop here.
2. If no, decide whether the number should be an asset of the business. If yes, get a fixed number that rings your mobile.
3. If no to both, run on mobile. That is a legitimate answer and we will not argue with it.
4. Whatever you choose, keep your existing number. It ports to all of these - see keeping your business landline number.
5. Then pick the product, which is the easy bit: business landline alternatives compares all five.

The bottom line

Nobody needs copper any more, and that part is not a choice. What most businesses still need is a fixed number that belongs to the business rather than to a person, and that more than one person can answer. That is available cheaply, works from a mobile, and survives staff changes and office moves. Mobile-only is a real answer for a real set of businesses, and if you are one of them we will tell you so.
