How to get a business phone number without a landline
Yes, you can get a proper UK business number with no landline at all. A virtual landline (hosted VoIP) gives you a real local, national or 0800 number that rings through an app on your existing mobile, with no phone line, no engineer and no hardware. A new number is usually live in minutes, and UK calls are normally included.
Can you really get a business number with no phone line?
Yes, and it is now the normal way new businesses do it. The trick is that the number does not live on a copper wire in a building. It lives in the cloud, and the call travels to you over the internet to an app on a phone or computer you already own. This is called a virtual landline, a virtual number, or simply a hosted VoIP number. The caller dials your number, your app rings, you answer, and to them it is an ordinary phone call.
Because there is no physical line, there is nothing to install. No BT engineer, no socket on the wall, no wait for an appointment, and no router to plug a special box into. You sign up online, pick a number, download an app, and you can take calls within minutes. If you are a sole trader, freelancer or brand-new business handing out your personal mobile right now, this is the simple upgrade to a professional setup without buying a second phone.
It is also future-proof. The UK's old copper phone network, the PSTN, switches off on 31 January 2027, so installing a traditional new landline today would be a dead end. A virtual landline already runs on the internet-based technology that replaces it, so you are starting on the right side of that change.
How to set up a business number without a landline, step by step
Getting set up is short and you can do all of it yourself. Follow these six steps in order and you will have a working professional number on your existing phone, with voicemail and business hours, in a single sitting.
- Choose your number type. Decide which number fits your business: a local 01 or 02 number for a regional feel, a national 03 number such as 0333 or 0345 that works UK-wide, or a 0800 freephone number that is free for callers. You can hold more than one.
- Pick a virtual landline provider. Choose a UK virtual landline or hosted VoIP provider. Look for inclusive UK calls, a mobile app and browser softphone, voicemail-to-email, call routing and free number porting if you want to move an existing number later.
- Download the app or use the browser softphone. Install the provider's app on your existing iOS or Android phone, or sign in to the browser softphone on a computer. Your new business number now rings on the device you already use, over wifi or mobile data.
- Set up voicemail, a greeting and business hours. Record or type a professional greeting, switch on voicemail-to-email so missed calls land in your inbox, and set business hours so the number does not ring out of hours. This is all done in the app, with no engineer.
- Start giving out the new number, or port your existing one. Put the new number on your website, email signature, listings and cards. If you already give out a number you want to keep, ask the provider to port it across so customers reach you on the same digits.
- Add teammates as you grow. When you take on staff or a partner, add users so calls ring more than one person, set up ring groups or a call menu, and share voicemail. The number scales with the business with no new lines.
That is the whole process. Most providers let you trial it first, so you can test calls in and out on your own phone before you put the number on anything public.
Which type of UK number should you choose?
The number you pick sends a quiet signal about your business, so it is worth a moment's thought. All three main types work the same way through the app and can ring on your mobile. The difference is what they say to a caller and who pays for the call.
| Number type | What it says | Who pays | Good for |
|---|---|---|---|
| Local (01 / 02) | A local, established presence in a specific town or city | Caller, at standard rates included in most call plans | Tradespeople, local services and anyone wanting a regional feel |
| National (03 / 0333 / 0345) | A nationwide business not tied to one area | Caller, charged the same as a standard 01 or 02 call | Online businesses, multi-area services and growing teams |
| Freephone (0800) | A free, customer-friendly line that encourages calls | You, the business, for inbound minutes | Sales lines, helplines and high-trust offers |
You do not have to pick just one. Many new businesses take a local 01 number to feel grounded in their area, then add an 0800 sales line later. Because there is no physical line behind any of them, holding more than one number is simply a setting in your account.
What you need, and what you do not
The list of what you actually need is short. You need a smartphone or computer you already own, an internet connection, and an account with a virtual landline provider. That is it. The app turns your existing handset into a business phone, and the connection can be wifi or your normal 4G or 5G mobile data, since each call only uses around 100 kbps.
Just as useful is the list of things you do not need. There is no second phone or SIM to buy, no line rental, no installation fee, no engineer visit, no router box, and no contract for a physical line. You keep your personal number private because business calls come in and go out through the app, not your own number. If you later want to keep a number you already advertise, free number porting moves it across so nothing on your marketing has to change.
Frequently asked questions
Can I get a business phone number without a landline?
Yes. A virtual landline, also called a virtual number or hosted VoIP, gives you a real UK business number with no physical phone line, no engineer visit and no hardware. The number rings through an app on your existing mobile or a browser softphone, and most people are set up in a few minutes.
How long does it take to set up a business number?
A brand-new number is usually live within minutes of signing up, because there is nothing to install. You choose the number, download the app and start taking calls. If you want to move an existing number across by porting, that part typically takes a few working days to about two weeks depending on the number type and your old provider.
What kind of business number can I get without a landline?
You can choose a local 01 or 02 number tied to a town or city, a national 03 number such as 0333 or 0345 that works anywhere in the UK and is charged at standard rates, or an 0800 freephone number that is free for callers. You can hold several numbers at once, for example a local number for your area and an 0800 for sales.
Does the number ring on my own phone?
Yes. The business number rings through an app on your existing smartphone, so you do not need a second handset or SIM. Business calls come in through the app while your personal number stays separate and private, and when you call out the business number shows on the other person's screen.
Is a business number without a landline cheaper than a real line?
Usually yes. There is no line rental, no installation charge and no hardware to buy, and UK calls are normally included in the monthly price. Most virtual landlines in the UK cost from around 5 to 15 pounds per user per month, which is typically less than a traditional business line plus call charges.
Do I need good broadband or wifi to use it?
You need a working internet connection, but not a fast one. Each call uses about 100 kbps, so a normal 4G or 5G mobile signal or any home or office wifi handles it easily. The app uses whichever connection your phone is on, so you can take business calls on the move.
