TL;DR — What you need to know

  • You can get a dedicated UK business mobile number in under 3 minutes
  • No need for a second phone, SIM card, or contract
  • Virtual number apps like Line let you text and call from your existing phone
  • Prices start from £1.70/month with no lock-in

If you're a tradesperson, freelancer, or small business owner in the UK, using your personal mobile number for work is a problem you've probably learned to live with. Customers calling at 9pm on a Sunday. No way to hand off calls when you're on a job. Texts from suppliers mixed in with family group chats.

Getting a separate business mobile number fixes all of this — and it's far easier (and cheaper) than most people think.

This guide walks you through every option available in the UK, what each one costs, and how to pick the right one for your business.

Why you need a separate business number

Using your personal number for business might seem fine when you're starting out, but it creates real problems as you grow:

  • No work-life boundary — customers can reach you 24/7 with no way to switch off
  • Missed opportunities — when you're on a job, calls go to voicemail (or nowhere)
  • No team handoff — if you hire someone, they can't answer your personal phone
  • Unprofessional image — a dedicated number signals you're a real, established business
  • GDPR exposure — your personal number on invoices, Checkatrade, and van signage means it's public forever

A separate business number solves every one of these problems — and the best part is you don't need a second phone.

Types of UK business phone numbers

Before you choose a method, it helps to understand what's available:

For most tradespeople and small businesses, a virtual mobile (07) number gives you the best of everything — customers can call and text, you don't need extra hardware, and you can manage it from your existing phone.

4 ways to get a business mobile number in the UK

Method 1: Second SIM card / dual-SIM phone

The old-school approach. Buy a SIM-only plan from any UK network and use it in a second phone or a dual-SIM handset.

Pros: Familiar, works offline, separate billing. Cons: You need a second phone (or a dual-SIM device). No team sharing. No business hours. Monthly contract usually required.

Cost: £5-15/month on a 12-24 month contract.

Method 2: Network business plan

EE, Vodafone, Three, and O2 all offer business mobile plans. These are essentially consumer plans with VAT invoices and sometimes multi-line discounts.

Pros: Support for multiple handsets, sometimes better coverage. Cons: 12-24 month contracts, hardware costs, no shared inbox or business features.

Cost: £15-30/month per line, plus handset costs.

Method 3: VoIP / landline number

Services like Google Voice (limited in the UK), Vonage, or 8x8 provide internet-based phone numbers. These are often 01/02 landline numbers rather than mobile 07 numbers.

Pros: Cheap, no hardware, call routing features. Cons: Usually a landline number (no SMS), can feel impersonal, often designed for larger teams with complex pricing.

Cost: £6-20/month per user.

A virtual mobile number is a real UK 07 number that lives in an app on your phone. You can text, call, and manage everything from your existing device — no SIM swap, no second phone.

Pros: Real 07 mobile number, SMS and calls, business hours, shared team inbox, no hardware, no contracts. Cons: Requires an internet connection for calls (Wi-Fi or mobile data).

Cost: From £1.70/month with Line.

What to look for in a business number provider

Not all business number services are created equal. Here's what matters:

  • Real mobile (07) number — not a landline or shared short code. Customers trust mobile numbers and can text them.
  • SMS and voice — you need both. Many VoIP services only do voice.
  • No long contracts — your needs change. Monthly rolling is ideal.
  • Shared inbox — if you have (or plan to have) a team, everyone should be able to see and reply to messages.
  • Business hours — automatically send calls to voicemail outside working hours so you can switch off.
  • Simple pricing — watch out for per-user, per-minute, and per-message fees that stack up. Look for inclusive credit bundles.
