If you’re running a UK business—especially a call centre or small service team—one of the first questions you’ll ask is: “How much will VoIP actually cost me per month?”
On the surface, VoIP looks simple and cheap. Providers advertise prices like £6, £10, or £15 per user. But the real cost can vary depending on features, usage, and hidden add-ons.
In this guide, we’ll break down real VoIP pricing in the UK for 2026, what affects the cost, and what hidden fees you should watch out for.
What Is the Average Cost of VoIP in the UK?
In 2026, most UK businesses pay:
- £6 – £10 per user/month → basic VoIP systems
- £10 – £15 per user/month → standard business systems
- £15 – £25+ per user/month → advanced call centre or enterprise systems
This pricing structure is consistent across most providers in the UK market.
Some premium systems with AI features, analytics, and contact centre tools can go even higher depending on requirements.
VoIP Pricing Breakdown (Simple Explanation)
To understand VoIP properly, you need to break it into different cost layers—not just the monthly fee.
1. Monthly User Cost (Main Cost)
This is the price per employee or “seat.”
- Entry-level: £6–£8/user/month
- Mid-tier: £8–£15/user/month
- Premium: £15–£25/user/month
This usually includes calling, voicemail, and basic app access.
2. Call Charges (Sometimes Included)
Many UK VoIP plans include unlimited UK calls, but not all.
Some providers:
- Include UK landline + mobile calls
- Charge per minute for international calls
- Offer fair usage limits
Always check the “fair usage policy” carefully.
3. Setup Costs
Most modern VoIP providers offer free setup, but not always.
Possible costs:
- £0 – £100 setup fee (depending on provider)
- Extra charges for complex call routing setups
- Training or onboarding for large teams
4. Hardware Costs (Optional but Common)
You don’t always need hardware, but many call centres still use desk phones or headsets.
- IP desk phones: £50 – £200 each
- Headsets: £20 – £150
- Optional rentals: £3 – £5/month per device
A typical 10-person office may still invest a few hundred pounds upfront.
5. Number Porting Fees
Moving your existing business number to VoIP is usually:
- Free with most providers
- Or £5 – £10 per number in some cases
This ensures you don’t lose your existing customer contact number.
Example: Real UK Small Business VoIP Cost
Let’s take a simple example:
A 10-person call centre using mid-range VoIP.
| Cost Item | Monthly Cost |
|---|---|
| 10 users @ £10 each | £100 |
| UK calls (included) | £0 |
| Extra features (recording, CRM) | £20–£50 |
| Total monthly cost | £100–£150/month |
One-time costs:
- Setup: £0–£50
- Hardware (optional): £200–£600
This is still far cheaper than traditional phone systems.
Hidden Costs You Should Watch Out For
This is where many UK businesses get surprised.
1. Call Recording Fees
Some providers charge extra for storing recordings.
2. CRM Integrations
Connecting VoIP with tools like Salesforce or HubSpot may cost extra.
3. International Calls
Not always included in “unlimited” plans.
4. Contract Lock-ins
Some cheaper plans require 12–24 month contracts.
5. Fair Usage Limits
“Unlimited calls” often have hidden usage caps.
Research shows many businesses only discover these costs after signing up.
VoIP vs Traditional Landline Costs (UK Comparison)
| Feature | VoIP | Traditional Landline |
|---|---|---|
| Monthly cost | £6–£25 per user | £25–£40 per line |
| Setup cost | Low or free | High installation fees |
| Call charges | Often included | Charged per call |
| Flexibility | High (remote work) | Low |
| Scalability | Instant | Slow and expensive |
Traditional systems can cost significantly more over time due to line rental and maintenance.
Why VoIP Is Cheaper in the Long Run
Even though pricing looks similar at first, VoIP saves money because:
- No physical phone lines
- No expensive maintenance contracts
- Easy scaling without infrastructure
- Lower international call costs
- Free software updates
Many UK businesses report savings of 40% to 70% after switching to VoIP.
Is Cheap VoIP Worth It?
Yes—but only in certain cases.
Cheap VoIP is good if:
- You are a small business or startup
- You have low call volume
- You only need basic calling features
It’s NOT ideal if:
- You run a call centre
- You need CRM integrations
- You rely on call analytics or reporting
- You want enterprise-level reliability
Cheap systems often lack scalability and advanced tools needed for growth.
Final Verdict
So, how much does VoIP really cost in the UK?
Realistic answer: £8–£15 per user/month for most businesses
Small setups: can go as low as £6/user
Call centres: usually £12–£25/user with advanced features
But the real key is not just price—it’s total value.
A slightly more expensive VoIP system can often save you money by improving efficiency, reducing missed calls, and giving better customer experience.
Final Thoughts
VoIP is now the standard communication system for UK businesses. Landlines are becoming outdated, expensive, and less flexible.
If you’re choosing a VoIP system, don’t just look at the monthly price—look at:
- Hidden fees
- Scalability
- Features
- Support quality
Because in the long run, the cheapest option is not always the most cost-effective one.
