Virtual Phone Number for Business in the UK: Top Options for 2026

Getting a UK virtual phone number costs anywhere from £5 to £50+ per month depending on the provider — but most businesses are paying for features they don't need. If you're a remote team, a growing startup, or an international company wanting a British presence, you've got more options in 2026 than ever before. This article covers the top virtual phone number providers for UK businesses, what each one actually costs, and how to pick the right setup without overpaying.

Key Takeaways:

• UK virtual phone numbers start from as little as £5/month, but per-seat pricing models can push costs to £30–£60 per user once add-ons are included
• Browser-based VoIP (like GlobCall) lets unlimited team members share one balance with no seat fees — UK landlines cost just $0.03/min to call outbound
• Local UK numbers (01/02 area codes) build more customer trust than 0800 numbers for B2B sales — studies show phone numbers on websites increase conversion by up to 30%

What Is a Virtual Phone Number and Why Do UK Businesses Need One?

A virtual phone number works exactly like a regular phone number — it rings, it receives calls, it shows up on caller ID — but it's not tied to a physical SIM card or landline socket. Industry estimates suggest over 60% of UK SMEs now use at least one virtual number, up from around 40% in 2022. The shift is practical, not trendy.

The appeal for businesses is straightforward. You get a UK number without a UK office. A Manchester area code, a London 020 number, or a national 03 number, all routed to whoever you want, wherever they are. Your team in Edinburgh answers calls intended for your London sales line. Your freelancer in Portugal picks up your Birmingham support number.

Common use cases include remote-first companies that want local presence, international businesses entering the UK market, sole traders who don't want personal numbers on their website, and e-commerce brands that need a human contact point to increase sales conversions.

The real question isn't whether you need one. It's which type fits your actual workflow.

The Main Types of UK Virtual Numbers

There are four number types you'll encounter, and choosing the wrong one will cost you either money or credibility with customers.

Geographic numbers (01/02) are area-specific — 020 for London, 0121 for Birmingham, 0161 for Manchester. They look like landlines, build local trust, and are often preferred in B2B settings where buyers want to feel they're dealing with someone nearby. Customers are more likely to call a 020 number than an 0800 one if they've never heard of your brand.

Non-geographic numbers (03) charge callers standard rates and are included in most mobile plans. They're often used by charities, public bodies, and businesses that want a single national number rather than a regional identity. Good for support lines.

Freephone numbers (0800/0808) are free for the caller. That's the draw. But you pay for inbound call costs, and some customers distrust 0800 numbers because they associate them with cold-callers and large corporations.

Virtual mobile numbers (07) give you a UK mobile-style number. Useful for sole traders and anyone who wants to appear reachable on mobile without handing out a personal number. Some providers now let you send and receive SMS on these too.

For most small businesses and remote teams, a geographic 01/02 number is the right starting point. The local area code does real work for you.

Top Virtual Phone Number Providers for UK Businesses in 2026

Here are the leading options, what they genuinely cost, and who they suit best.

1. GlobCall

GlobCall is browser-based — no app download, no desk phone, no SIM card. You get UK local numbers across 100+ countries, shared balance across unlimited team members, and zero per-seat fees. Outbound calls to UK landlines run at $0.03/min. Inbound calls are included with your UK number subscription.

This model is unusual. Most providers charge per user per month, which means a team of 10 quickly becomes expensive. GlobCall charges based on actual usage and one number fee, so whether two people answer calls or twenty, the cost stays predictable. It's particularly strong for distributed remote teams and international companies setting up a UK presence without a physical office.

You can be up and running in minutes. Two clicks to call, no hardware. If your team already works from browsers, the friction is essentially zero.

GlobCall also covers outbound international calls. If your UK number gets a call that needs escalating to someone who then needs to call a client in Germany ($0.04/min) or India ($0.08/min), all of that flows from the same shared account.

Worth reading: how teams use shared balance across unlimited members — the cost difference versus per-seat models is significant at scale.

2. RingCentral

RingCentral is one of the largest business phone platforms globally. Their UK offering includes virtual numbers, call routing, IVR menus, CRM integrations, and a full unified communications stack. If you want enterprise-grade features — call analytics, supervisor dashboards, complex ring groups — RingCentral delivers.

The cost reflects that. Plans start around £20–£25 per user per month before add-ons. A 10-person team is looking at £200–£300/month minimum. International calling rates are bundled but limited — exceed your minutes and costs rise fast.

RingCentral is overkill for most SMEs. It's built for companies with dedicated IT teams and complex call centre workflows. If that's you, it's worth considering. If you're a 5-person startup, you'll pay for features you'll never touch.

See how RingCentral's international calling rates compare to browser VoIP in practice.

3. Vonage (now part of Ericsson)

Vonage has been through corporate transitions since the Ericsson acquisition, but the UK product remains active in 2026. They offer UK virtual numbers, a programmable API layer useful for developers, and standard business phone features. Pricing is per-seat — typically £15–£30/user/month depending on the tier.

Vonage suits tech companies that want to build calling into their own apps via API. The Vonage Communications Platform gives developers control over call flows in ways that most hosted phone systems don't. For non-technical businesses, though, that flexibility adds complexity without adding value.

The Vonage alternatives page breaks down where it falls short for smaller teams. The best VoIP service for small business in 2026 roundup puts it in broader context.

4. JustCall

JustCall positions itself as a sales and support team phone system, with UK virtual numbers, SMS capabilities, call recording, and integrations with HubSpot, Salesforce, Pipedrive, and others. It's popular with outbound sales teams.

Pricing starts around $19–$29 per user per month (billed in USD, though UK numbers are available). The CRM integrations are genuinely useful if your team lives in a sales platform — click-to-call from HubSpot is a real time-saver. Call analytics and coaching features are more developed than most SME-focused providers.

The catch is that per-seat pricing adds up. And if your team does any international outbound calling — prospects in Germany or Australia, for example — rates can vary significantly. For heavy international outbound, JustCall alternatives may give you better per-minute economics.

5. Microsoft Teams Phone

Since Skype was shut down in May 2025, many individuals and businesses migrated to Microsoft Teams. Teams Phone is Microsoft's calling add-on — it gives Teams users an actual PSTN phone number and the ability to make and receive regular calls.

For businesses already paying for Microsoft 365, Teams Phone is a logical extension. UK numbers are available. You pay per-user per-month for the calling plan (typically £8–£12/user on top of existing M365 licences), plus per-minute rates for international calls.

The integration with Teams meetings, calendar, and chat is tight. If your company already runs on Microsoft, this can reduce app sprawl. If you're not a Microsoft shop, the licensing complexity is a real barrier. The international call rates aren't competitive either — Microsoft Teams international calling costs compared to standalone VoIP shows the gap clearly.

6. Grasshopper

Grasshopper is US-founded but offers UK virtual numbers with a notably simple setup. You get a number, call forwarding, voicemail transcription, and basic IVR — all in a straightforward package. Plans start around $28/month for a single number with three extensions.

It works best for sole traders and very small businesses that want a professional number without managing a complex phone system. You forward calls to your existing mobile, and Grasshopper handles the virtual layer. No fuss.

The limitations show at scale. No team analytics, no CRM integrations, limited international calling. Fine for a consultant or a two-person startup. Less suited to a growing team with real call volume.

7. 8x8

8x8 competes directly with RingCentral in the mid-market and enterprise space. UK virtual numbers, unlimited calling to certain countries, video conferencing, and contact centre features are all available. Their X2 plan, aimed at SMEs, starts around £20/user/month in the UK.

The unlimited calling to 14 countries on the base plan is a genuine differentiator if your team calls those specific destinations constantly. For outbound-heavy teams targeting the UK, US, and western Europe, the economics can work. But "unlimited" typically means "unlimited subject to fair use policy," so read the terms carefully.

For most UK SMEs doing moderate call volume, pay-as-you-go per-minute pricing will still come out cheaper than a monthly per-seat plan. The pay-as-you-go vs monthly subscription comparison is worth reviewing before committing.

How to Choose the Right UK Virtual Number Provider

Most businesses overthink the feature list and underthink the cost model. Here's a practical decision framework.

Start with team size and growth trajectory. If you have 3 people today and might have 15 in 18 months, per-seat pricing will hurt you. A shared-balance model scales without the cost cliff. If you're staying small, a flat monthly package makes budgeting easy.

Think about where your calls go. A UK virtual number handles inbound. But your team will make outbound calls too — to clients, suppliers, partners. If those are international, per-minute rates matter enormously. Calling a client in Nigeria at the wrong provider's rate versus GlobCall's $0.33/min can mean real money at volume. See how much international calls actually cost in practice.

Browser vs. app vs. hardware. Browser-based calling suits remote and distributed teams — no download, works anywhere with internet. App-based systems like RingCentral and JustCall need installation and updates. Hardware-based systems suit fixed office environments. Be honest about how your team actually works.

CRM integration vs. simplicity. If your sales team is in HubSpot or Salesforce all day, a system that integrates is worth paying for. If you're a founder taking 20 calls a week, a $30/seat/month system is more than you need.

Inbound vs. outbound ratio. A support team that mostly receives calls needs different infrastructure than a sales team that mostly makes them. Inbound-heavy teams benefit from IVR and call routing features. Outbound-heavy teams need low per-minute rates and fast dialling.

The VoIP for small business in the UK comparison goes deeper on this framing if you want more detail.

Setting Up a UK Virtual Number: What to Expect

The actual process is simpler than most people expect. Most providers can get you a working UK number in under 30 minutes.

Step 1: Choose your number type. Geographic (01/02), national (03), or mobile (07)? If you want a London presence, pick a 020 number. If you're national, go 03. If you want a specific city, check what's available — 0161 for Manchester, 0113 for Leeds, 0121 for Birmingham.

Step 2: Set up call routing. Who answers? You can route to a single person, ring a group simultaneously, or set up a basic IVR ("Press 1 for sales, Press 2 for support"). For small teams, simultaneous ring to all available members is usually simplest.

Step 3: Configure voicemail and out-of-hours behaviour. Set a professional voicemail message. Decide what happens when no one answers after hours — voicemail, an automated message, or forwarding to a mobile. Don't leave this at the default.

Step 4: Test from an external number. Always call your own number from a mobile or a friend's phone before going live. You'll catch routing errors, voicemail greeting issues, or call quality problems before customers do.

Step 5: Put the number everywhere. Website header, email signature, Google Business Profile, LinkedIn company page. A number that's hard to find defeats the purpose. The guide on adding a phone number to your website has useful tips even if you're not on Shopify.

Frequently Asked Questions

Can I get a specific UK area code (like 020 London) without being based there?

Yes. Virtual number providers assign geographic numbers regardless of where you or your team are physically located. A company based in Dublin or Berlin can have a 020 London number that routes to any device anywhere. Availability of specific area codes depends on the provider's inventory.

What's the difference between a virtual number and a VoIP number?

They overlap but aren't identical. A virtual number is a phone number not tied to a physical line — it could route to a mobile, a landline, or a VoIP system. A VoIP number is specifically delivered over internet protocol. Most virtual numbers in 2026 are VoIP-based, but not all VoIP services give you an actual inbound phone number.

Do UK virtual numbers work for two-factor authentication SMS?

It depends on the provider and the platform sending the SMS. Many virtual and VoIP numbers are flagged by SMS verification systems (like those used by banks or Google). If SMS verification is a priority, check with the provider before signing up. Some offer dedicated SMS-capable numbers.

How much does a UK virtual number cost per month?

Basic numbers start from £5–£10/month at providers like Grasshopper or smaller UK-focused services. Mid-range platforms like JustCall and 8x8 bundle numbers into per-seat plans at £15–£30/user/month. Browser-based services like GlobCall include a UK number as part of a usage-based model with no per-seat fees.

Is a UK virtual number legal for business use?

Completely legal. UK virtual numbers comply with Ofcom regulations as long as they're used in line with standard telecommunications law. You can't use them for unsolicited cold-calling in violation of PECR rules, but that applies to any phone number. For standard business communications, there are no restrictions.

Summary

A few things to keep in mind before you choose:

• Number type matters for trust — geographic 01/02 numbers outperform 0800 for B2B credibility
• Per-seat pricing scales badly — shared-balance models like GlobCall keep costs flat as your team grows
• Browser-based calling removes friction — no app, no hardware, works anywhere with internet
• Outbound rates matter as much as the number itself — if your team calls internationally, per-minute economics determine your real bill
• Setup takes under 30 minutes — the operational barrier is lower than most businesses expect

Whether you're a solo founder wanting a professional number or a 50-person team building a UK market presence, there's a right-sized option here. Don't pay per-seat fees for features you're not using.
