VoIP vs Zoom Phone: Which Is Better for a Small UK Business?

Zoom became a fixture for most businesses during the pandemic. If your team already runs meetings through Zoom, it's natural to ask: should we just add Zoom Phone and handle calls there too?

It's a fair question. This post gives you a straight answer.

We're VoIPninjas — a direct UK VoIP provider based in Christchurch, Dorset. We have a clear interest in you choosing us. We'll tell you when Zoom Phone makes sense, and we'll tell you when it doesn't. You can decide.

What Is Zoom Phone?

Zoom Phone is a cloud-based business phone system built into the Zoom platform. It lets you make and receive calls from within the same Zoom app you already use for video meetings.

It supports UK phone numbers, DDIs, call recording, auto-attendant, and most of the features you'd expect from a modern business phone system. It's a real, capable product — not a gimmick.

The complication is the pricing structure.

What Does Zoom Phone Actually Cost?

This is where things get murky.

Zoom Phone is an add-on. You can't use it standalone. You need a Zoom Pro plan (or higher) to access it, which currently runs around £11.99 to £15.99 per user per month in the UK.

On top of that, you pay for Zoom Phone itself. The options broadly break down like this:

• Metered plan: Cheaper monthly fee, but you pay per minute. Fine for very low call volumes. Can get expensive fast if your team makes regular outbound calls.
• Unlimited regional plan: Covers unlimited UK calls. Currently around £8–12 per user per month on top of your Zoom subscription.

Add those together and you're typically looking at £20–28 per user per month for a complete, properly functioning setup.

That's not a criticism — it's just the reality of how the product is packaged. If you're already paying for Zoom Pro, you're partway there. But if you're buying Zoom primarily to get a phone system, you're paying a premium.

Side-by-Side Comparison

When Zoom Phone Makes Sense

Be honest about this: Zoom Phone is a good product in the right context.

If your team is already deep in Zoom — daily video calls, Zoom Rooms, Zoom Webinars, deep integrations with your CRM — then adding Zoom Phone is a reasonable move. One interface for everything. Your team already knows how to use it. No new app to learn, no context-switching between tools.

For businesses that run on Zoom, the cost premium can be justified. You're not paying for a phone system in isolation — you're consolidating your communication stack into one platform.

Zoom also has solid enterprise integrations and a mature admin console. If you manage a complex organisation that already uses Zoom's broader ecosystem, the admin experience is relatively coherent.

One thing worth checking: Zoom Phone's UK number availability has historically lagged behind the US rollout. Standard geographic numbers and DDIs work well. If you have specific number type requirements — certain non-geographic formats, for example — verify availability before committing.

When a Dedicated VoIP System Makes More Sense

For a lot of small UK businesses, the situation is different.

You use Zoom occasionally for client calls or the odd team meeting. It's one of several tools you use, not the backbone of your operation. In that case, Zoom Phone is an expensive overlay on a tool you're already paying for moderately.

You'd be paying £20–28 per user per month for a phone system — a large chunk of which funds a video platform you don't rely on heavily.

A dedicated VoIP system like ours costs less, does everything you need for business calling, and doesn't require you to anchor your phone system to a third-party video platform.

Contracts. Zoom Phone is typically sold on annual terms. If your business changes — headcount goes up or down, your needs shift — you're locked in. Our plans are 28-day rolling. You scale up or down when you need to, not when your contract allows.

Support. We're a UK-based direct provider. When something needs sorting, you're talking to us — not navigating a support queue for a global platform with millions of users.

Dependency. Your phone system working correctly should not depend on whether Zoom is having a service issue. Separate systems, separate risks.

Simplicity. If you don't live in Zoom day-to-day, setting up and managing Zoom Phone adds friction. A dedicated VoIP system built for business calling tends to be more straightforward if telephony is the primary requirement.

The Honest Summary

Zoom Phone is worth considering if Zoom is central to how your business communicates and you want everything under one roof.

For most small UK businesses that want a capable, affordable phone system without tying themselves to the Zoom ecosystem, a dedicated VoIP provider is the cleaner, cheaper option.

Our Samurai plan at £14.99/user/month gives you 750 minutes, call recording, auto-attendant, and a mobile app. No annual contract. No dependency on another platform.

Frequently Asked Questions

Can I use Zoom Phone without a Zoom Pro subscription?

No. Zoom Phone is an add-on to Zoom's paid plans. You need at least Zoom Pro to use it, which adds to your overall monthly cost. Factor that in when comparing total prices.

Does Zoom Phone support UK phone numbers?

Yes. Zoom Phone supports UK geographic numbers and DDIs, and number porting is available. If you have specific number format requirements, check availability with Zoom directly before committing.

What's the difference between Zoom Phone metered and unlimited?

The metered plan has a lower monthly fee but charges per minute for calls. If your team makes regular outbound calls, costs can add up quickly. The unlimited plan covers UK calls for a fixed monthly fee but costs more upfront. For most businesses making a reasonable volume of calls, unlimited works out cheaper overall.

How long does it take to get set up with VoIPninjas?

We get new customers live within 10 working days. If you're porting an existing number, timescales can vary slightly depending on your current provider, but we'll keep you informed throughout. Call us on 0330 043 2388 if you have specific requirements and we'll give you a straight answer.
