How much does a business phone system cost in the UK? (2026)
A UK hosted business phone system typically costs £7 to £30 per user per month, with UK calls usually included. A five-person team usually spends around £50 to £90 a month all in. Setup and number porting are normally free because the system runs in the cloud, with no upfront hardware bill.
What does a UK business phone system cost per user?
The price you pay almost always comes down to a per-user monthly fee. For a modern hosted (cloud) phone system in the UK in 2026, that fee usually falls between £7 and £30 per user per month. Where you land in that range depends on which features you need rather than how many people you have.
At the lower end, around £7 to £12 per user, you get the essentials: a UK number, the ability to make and receive calls from an app or desk phone, voicemail and basic call handling. In the middle, roughly £12 to £20 per user, you add things like an auto-attendant menu, ring groups, call queues and call recording. At the top, around £20 to £30 per user, you get the advanced kit: AI call transcription and summaries, CRM integration, detailed analytics and AI receptionist features.
Crucially, UK calls are usually inexpensive - either bundled into the per-user price or charged at a few pence per minute - so call costs are easy to predict. That is one of the big differences from the old world of line rental plus metered calls. The headline per-user figure is usually your real monthly cost for everyday UK calling.
What does it cost by team size?
Because pricing is per user, the maths is simple: multiply the per-user rate by the number of people who need a phone. The table below shows typical UK market monthly costs at a mid-range rate of about £12 to £18 per user, which covers most growing small businesses with proper call handling.
| Team size | Typical monthly cost (market range) | Typical yearly cost |
|---|---|---|
| 1 user (sole trader) | £7 to £30 | £84 to £360 |
| 5 users | £50 to £90 | £600 to £1,080 |
| 10 users | £100 to £180 | £1,200 to £2,160 |
| 25 users | £250 to £450 | £3,000 to £5,400 |
| 50 users | £450 to £850 | £5,400 to £10,200 |
These are general UK market figures, not a quote from any single provider. Larger teams often negotiate a lower per-user rate, and some providers offer cheaper tiers for staff who only need basic calling. The key point is that you only pay for the people who need a line, and you can add or remove users in minutes.

What is included in the monthly price?
A well-priced hosted plan should be close to all-inclusive. Before you sign, check exactly what your per-user fee covers, because the value is in the bundle, not just the headline number. A typical mid-range UK plan includes:
- A UK phone number per user, plus shared numbers for the business.
- Inclusive UK landline and mobile calls (check the minute allowance).
- Apps for mobile, web browser and desk phone, so staff can work anywhere.
- Call handling: auto-attendant, ring groups, call queues, hold, transfer and business-hours routing.
- Voicemail to email and basic reporting.
- Free setup and number porting in most cases.
Higher tiers layer on call recording, AI transcription and summaries, CRM logging and an AI receptionist. The smart way to compare quotes is to write down the features you actually need, then check which provider includes them at the lowest all-in per-user price rather than as paid extras.
How does this compare to a traditional phone system?
The contrast with an old-style on-premise system is stark, and it is the main reason small businesses are switching. A traditional on-premise PBX is a physical box installed in your building. You buy the hardware upfront, often £1,000 or more per user once you include handsets, the system and installation, then pay ongoing line rental and maintenance on top. You also own the risk: if it breaks, it is your problem.
Hosted VoIP flips that model. There is no box to buy, so the upfront cost is usually just the optional desk phones (about £40 to £150 each), and many businesses skip those and use apps. The monthly per-user fee replaces line rental, metered calls and maintenance in one predictable figure. Over a three to five year window, the total cost of ownership for a small business is almost always lower with hosted. It is also why hosted is the natural fit ahead of the PSTN switch-off. See VoIP vs landline for the full comparison.
What hidden costs should I watch for?
The advertised per-user price is not always the whole story. A few things can quietly push your bill up, so ask about them before you commit.
| Possible extra cost | What to check |
|---|---|
| Number ranges | 0800, 0808 and some premium numbers can carry an extra monthly fee or different call rates. |
| Add-on features | Confirm whether call recording, AI transcription and analytics are included or charged separately. |
| Contract length | Longer contracts can lower the rate but lock you in. Check early-exit terms. |
| Extra numbers | Additional direct dial numbers may cost a small monthly fee each. |
| International and special rates | Calls outside the UK and to non-geographic numbers are usually metered. Check the rate card. |
| Hardware | Desk phones are optional. Only buy them if staff genuinely prefer a handset to an app. |
The cleanest providers quote one clear all-in price per user and tell you upfront what sits outside it. If a quote looks unusually cheap, it is worth checking what has been left out.

Frequently asked questions
How much does a business phone system cost per user in the UK?
Most UK hosted phone systems cost between £7 and £30 per user per month, depending on the features you choose. Entry plans with calling and an app sit at the lower end, while plans with call recording, AI transcription and analytics sit higher. Calls within the UK are usually included.
Is there an upfront cost to set up a VoIP phone system?
Usually not for hosted VoIP. Setup, account configuration and number porting are typically free or low cost because the system is in the cloud with nothing to install. Your only optional upfront spend is desk phones, at roughly £40 to £150 each, and many businesses skip these entirely and use apps.
Is it cheaper than a traditional phone system?
Generally yes. An on-premise PBX can cost £1,000 or more per user upfront plus ongoing maintenance and line rental. Hosted VoIP removes that hardware cost and bundles UK calls, so total cost of ownership over a few years is normally much lower for small and medium businesses.
What hidden costs should I watch for?
Check the contract length and early-exit terms, whether premium and 0800 numbers cost extra, whether call recording and AI features are add-ons or included, the price of extra numbers, and international or mobile call rates. A clear all-in monthly price per user is the easiest to budget for.
Does it cost more to keep my existing number?
Number porting is normally free or included when you move to a new provider, so keeping your existing business number does not usually add to the cost. The new provider handles the transfer for you and your number rings on the new system once it completes.
