Two hosted VoIP quotes can look almost identical on the first page and end up very different on the invoice. One is cheaper per user but charges for call recording, mobile calls and a handful of other things. The other costs more upfront but includes most of what you need.
If you are comparing hosted telephony for a UK business, the headline price is only the starting point. This guide explains what is normally included, what often costs extra, and how to compare quotes so you pay for what you will actually use.
How Hosted VoIP Pricing Is Built
Most providers price hosted VoIP services in layers rather than as one flat figure.
The per-user licence is the main monthly charge. It covers access to the cloud PBX, which handles call routing, voicemail, extensions and similar features without an on-site phone system.
Call charges are usually separate or partly bundled. Some plans include a set allowance of UK landline and mobile minutes, while others bill per minute.
Numbers carry their own cost. Geographic numbers, direct dial ranges and non-geographic numbers are often charged individually.
Handsets and hardware may be bought outright, leased or rented, or avoided entirely by using softphone apps on laptops and mobiles.
One-off fees can include setup, configuration, number porting and training.
Understanding these layers makes quotes much easier to compare, because you can see where one provider is cheap and another is not.
What a Standard Price Usually Includes
Core features vary, but most reputable providers include the following in their standard licence:
- Auto attendant (the “press 1 for sales” menu)
- Ring groups and hunt groups
- Voicemail, often with email delivery
- Call forwarding and basic call management
- Desktop and mobile app access
- A web portal for making simple changes
For a small office, this is often enough to replace an ageing business phone system without losing any day-to-day capability.
What Often Costs Extra
This is where the real price differences appear.
Call recording
Often an add-on, and sometimes charged by storage or retention period. It matters for financial services, legal firms and anyone handling disputes.
Call centre and reporting tools
Queues, wallboards and detailed analytics are frequently reserved for higher tiers. A sales team may need them, while a five-person practice likely does not.
Unified communications and Teams integration
Linking your phone system with Microsoft Teams or similar platforms may be included in some plans and charged separately in others.
Calls to mobiles and international destinations
“Unlimited calls” typically refers to UK landlines and sometimes mobiles, and usually comes with a fair use policy. Check what is excluded.
Extra numbers, additional sites and CRM integration
Each can add to the monthly bill, particularly for growing, multi-location businesses.
Cheap, Mid-Range and Premium: What Changes
Providers vary, but plans usually follow a similar pattern.
Entry-level plans cover the basics: calling, voicemail and simple routing. They suit small teams with straightforward needs, though support may be limited to email or business hours.
Mid-range plans add features such as call recording, more advanced routing and integrations. This is where most SMEs end up.
Premium plans add contact centre functionality, advanced analytics, priority support and stronger service commitments.
Searching for the cheapest UK VoIP providers will bring up plenty of entry-level offers, and some are perfectly good. The key is to check whether the plan covers your real needs before comparing on price alone. Equally, the best UK VoIP providers for you are not necessarily those with the longest feature list. They are the ones whose included features match how you work.
A Realistic Example
Consider a 25-person estate agency with two branches. Staff work from the office, from home and on the road, so mobile app calling is essential. The business also wants call recording for compliance and customer disputes.
Quote A is the lowest per user but charges extra for recording and for calls to mobiles. Quote B is higher per user and includes both. Once the agency adds up its expected call recording and its heavy mobile usage, Quote B comes out as the better value, even though it looked more expensive at first.
The lesson is simple: price against your own usage, not the brochure.
The Costs People Forget
Beyond the monthly bill, a few practical factors affect the real cost of switching.
Your internet connection. Hosted VoIP depends on it. A weak or congested broadband line may need upgrading, or a backup connection added.
Existing equipment. Some desk phones can be reused, others cannot. Softphones can reduce hardware spend, but not everyone enjoys using them all day.
Contract length and exit terms. Longer terms often lower the monthly price but limit flexibility.
Migration support. Number porting and setup can take effort. Some providers handle this thoroughly, others leave much of it to you.
How to Compare Quotes Properly
A simple method keeps comparisons fair.
- List the features you actually need, not the ones that sound useful.
- Pull a month of call data from your current provider, including mobile and international calls.
- Ask each provider to quote against that same list and data.
- Request itemised pricing, including setup, numbers, recording and support.
- Check contract length, notice periods and how numbers are ported out.
For businesses still using ISDN lines, it also helps to ask providers whether a hosted system or SIP trunking alongside an existing PBX is the better fit. A provider such as Wavetel Business, which works with UK organisations on VoIP and business communications, should be able to explain both routes and what each would cost for your setup.
Frequently Asked Questions
Is hosted VoIP cheaper than a traditional phone system?
It often is over time, since there is no on-site PBX to maintain and fewer line rental charges. However, savings depend on usage, add-ons and contract terms, so compare real quotes rather than assuming.
What is the difference between hosted VoIP and SIP trunking?
Hosted VoIP replaces your phone system with a cloud PBX. SIP trunking keeps your existing on-site PBX and only changes how it connects to the phone network.
Does unlimited calling really mean unlimited?
Not always. Most plans include fair use policies, and some exclude mobiles, international or non-geographic numbers. Check the terms before you rely on it.
Do I need new handsets?
Not necessarily. Many businesses use softphone apps, and some existing handsets can be reused. Check compatibility with each provider.
How long does it take to move to hosted VoIP?
Setup can be quick for simple cases, but number porting often sets the timeline. Ask for realistic dates in writing.
Conclusion
A hosted VoIP price is only meaningful when you know what sits behind it. The per-user figure covers the basics, while recording, integrations, call types and support often determine the final bill.
Your practical next step: write down the features you genuinely need, gather a month of call data, and ask two or three providers for itemised quotes against it. The cheapest line on the page is rarely the cheapest over the length of the contract.
