When businesses start reviewing their communication systems, one of the first questions they ask is:
“How much does a business phone system actually cost?”
The answer depends on several factors, including the size of your business, the features you need, and how your system is set up.
However, understanding typical UK pricing can help you make an informed decision — and avoid unexpected costs.
What Types of Business Phone Systems Are Available?
Most businesses today are choosing between:
- Traditional phone systems (line-based)
- Cloud-based systems (VoIP)
With the upcoming PSTN Switch Off, many organisations are now moving towards internet-based solutions.
Typical Costs for Business Phone Systems in the UK
1. Traditional Systems
Older, line-based systems typically involve:
- Line rental costs
- Maintenance fees
- Hardware costs
- Call charges
These costs can vary widely, but businesses often find they are:
- Less flexible
- More expensive to maintain
- Difficult to scale
2. Cloud-Based (VoIP) Systems
Modern VoIP systems are usually priced per user, per month.
Typical costs:
- £10 – £20 per user/month (basic setup)
- £20 – £35 per user/month (more advanced features)
These costs often include:
- Call handling features
- Mobile and desktop apps
- System maintenance
- Updates and improvements
What Affects the Cost?
Several factors influence pricing:
- Number of users
- Required features (call recording, reporting, integrations)
- Call volumes (UK vs international)
- Hardware (desk phones vs softphones)
- Installation and setup requirements
Understanding these variables helps avoid underestimating your budget.
Hidden Costs to Watch Out For
Not all providers are transparent about pricing.
Common hidden costs include:
- Setup or onboarding fees
- Charges for changes or support
- Additional costs for features
- Call charges outside of bundles
It’s important to understand exactly what’s included before making a decision.
Cost vs Value: What Should You Focus On?
While cost is important, it shouldn’t be the only factor.
A cheaper system may lead to:
- Poor call quality
- Limited flexibility
- Lack of support
- Missed business opportunities
A well-designed system should:
- Support remote and hybrid working
- Improve customer experience
- Provide visibility into call activity
- Scale with your business
Why Businesses Are Moving to Cloud Systems
Many organisations are moving away from traditional systems because cloud-based solutions offer:
- Greater flexibility
- Lower upfront costs
- Easier management
- Better integration with IT systems
They also align with the UK’s move away from legacy infrastructure.
How IT and Telephony Work Together
Modern phone systems are no longer standalone.
They rely on:
- Your internet connection
- Your network setup
- Your wider IT environment
This is why businesses increasingly choose a provider that can manage both IT and communications together.
