Why Line vs traditional business phone providers?
Most business phone services charge £7-30/month per user and lock you into annual contracts. Line does things differently.
From £1.70/mo — not £7-30/user
Providers like bOnline charge from £7/user/month. BT Business phone lines start at £15+/month before you even make a call. Line gives you a real UK business number, SMS, and voice calls from £1.70/month — the most affordable business phone line in the UK.
SMS and calls included — not sold separately
Most business phone providers sell voice calls and SMS as separate products with separate charges. Line bundles calls, SMS, and a shared team inbox into every plan. One number, one bill, one inbox for everything.
3-minute setup — not 3-week installation
Traditional business phone lines require engineer visits, hardware installation, and weeks of waiting. With Line, you sign up, choose a number, and start receiving calls in minutes. No hardware, no engineer, no waiting — just download the app and go.
No contracts — not 12-month lock-ins
Many business phone providers require annual commitments and charge early termination fees. Line is pay monthly with no contracts. If it does not work for you, cancel anytime — no questions, no penalties, no notice period.
Business phone number FAQ
Common questions about getting a business phone number in the UK.
How do I get a business phone number in the UK?
With Line, you can get a UK business phone number in under 3 minutes. Sign up, browse the available numbers, and pick a UK mobile (07), national (01/02), or local number. Your number is active immediately — no porting, no paperwork, no waiting for a SIM card. You can start receiving calls and SMS straight away from any device.
How much does a business phone number cost?
Line starts at £1.70 per month, which includes a real UK phone number with SMS, voice calls, and a shared team inbox. There are no setup fees, no per-seat charges, and no annual contracts. This makes Line significantly cheaper than alternatives like bOnline (from £7/user/month) or traditional business phone lines that often cost £15-30/month before call charges.
Can I use a business phone number on my personal phone?
Yes. Line works as an app on your existing smartphone, so you can make and receive business calls from your personal phone without giving out your personal number. Incoming calls show that they are coming through your business line, so you always know when it is a work call. You can also use Line on your desktop or tablet at the same time.
What is the difference between a business phone number and a personal number?
A business phone number is a dedicated number used exclusively for your business communications. It separates your work and personal calls, projects a professional image to customers, and can be shared across a team. With Line, your business number also gets SMS, a shared inbox, and call management features that a personal number does not have.
Do I need a landline for a business phone number?
No. Line is a cloud-based business phone system, so you do not need a landline, desk phone, or any hardware. Your business phone number works entirely over the internet — on your mobile, laptop, or tablet. This is why modern businesses are moving away from traditional phone lines to virtual business numbers like Line.
Can I keep my existing business phone number?
Yes, Line supports number porting. If you already have a UK business phone number with another provider, you can transfer it to Line and keep the same number. The porting process is handled by our team and typically takes a few working days. In the meantime, you can use a new Line number immediately.
What types of UK business phone numbers are available?
Line offers three types of UK business numbers. Mobile numbers (07) are the most common and work well for businesses that want a familiar, contactable number. National numbers (01/02) give a professional, location-based presence — for example, an 020 London number or 0161 Manchester number. You can also choose a number that suits where your customers are based.
How is Line different from other business phone providers?
Line combines calls, SMS, and a shared team inbox in one plan from £1.70/month — most competitors charge separately for each. There is no per-seat pricing, no annual contract, and no hardware to install. Unlike traditional providers such as BT Business or bOnline, Line is entirely cloud-based and takes minutes to set up instead of days or weeks. You also get SMS messaging included, which most business phone providers charge extra for.
