Introduction
One of the first questions business owners ask when upgrading their phone system is simple.
How much is this going to cost?
The answer depends on several factors, including the type of system, the size of your team, and the features you need.
In this guide, we will break down the real costs of business phone systems in the UK, so you know what to expect and how to make the right decision.
Why understanding pricing matters
Choosing a phone system is not just about finding the cheapest option.
It is about finding the right balance between cost, reliability, and features.
With the UK moving away from traditional landlines, businesses are now investing in digital systems that offer better performance and long term value.
According to Ofcom, all landline services are being upgraded to digital networks as part of a nationwide transition.

This shift is also changing how pricing works.
The main types of business phone systems
Before looking at costs, it is important to understand the different options available.
Traditional phone systems
These include landlines and ISDN based systems that rely on copper infrastructure.
They usually involve:
- Physical hardware on site
- Line rental charges
- Maintenance costs
However, these systems are being phased out as part of the UK landline switch off.

VoIP and cloud based systems
These systems use the internet to handle calls.
They are typically subscription based and include features such as call routing, reporting, and mobile access.
This is now the most popular option for modern businesses.
How much does a business phone system cost in the UK
Let us break this down into realistic ranges for 2026.
Setup costs
For a new system, you may need to pay for:
- Installation
- Configuration
- Handsets or equipment
Typical range:
- Small business: £100 to £500
- Medium business: £500 to £2000
Cloud systems often have lower setup costs compared to traditional systems.
Monthly costs per user
This is where most of the ongoing cost comes from.
For VoIP systems, pricing is usually per user, per month.
Typical range:
- Basic plans: £5 to £10 per user
- Standard plans: £10 to £20 per user
- Advanced plans: £20 to £50 per user
These plans often include features that would cost extra on traditional systems.
Call costs
Many VoIP providers include:
- Free internal calls
- Bundled minutes
- Competitive rates for external calls
Traditional systems often have higher call charges and less flexibility.
Maintenance and support
Older systems usually require ongoing maintenance, which can increase costs over time.
VoIP systems often include support within the monthly fee, making costs more predictable.
What affects the total cost
No two businesses are the same, so pricing can vary.
Here are the main factors that influence cost.
Number of users
The more users you have, the higher the total monthly cost.
However, many providers offer discounts for larger teams.
Features required
Basic systems are cheaper, but adding features such as:
- Call recording
- Analytics
- Integration with other tools
can increase the price.
Hardware vs software
If you choose physical desk phones, there will be an upfront cost.
Some businesses prefer softphones, which work on computers or mobile devices and reduce hardware expenses.
Internet connectivity
VoIP systems rely on internet quality.
If your current connection is not suitable, you may need to upgrade your broadband or consider a leased line.
Hidden costs to watch out for
Many businesses focus only on the monthly price and overlook hidden costs.
These can include:
- Installation fees
- Contract lock ins
- Upgrade charges
- Maintenance fees
Industry providers highlight the importance of understanding total cost rather than just headline pricing.

Traditional vs VoIP cost comparison
In most cases, VoIP systems offer better long term value.
Traditional systems may seem cheaper at first, but they often come with:
- Higher maintenance costs
- Limited features
- Expensive upgrades
VoIP systems typically provide:
- Lower ongoing costs
- More included features
- Greater flexibility
As the UK moves towards digital communication, traditional systems are becoming less cost effective.
How to choose the right option for your budget
Choosing the right system is not just about price.
It is about value.
Here are a few tips.
Focus on long term savings
A slightly higher monthly cost can often save money over time if it reduces maintenance and improves efficiency.
Choose only what you need
Avoid paying for features you will not use, but make sure your system can scale as your business grows.
Get a tailored quote
Every business is different. A customised quote will give you a clearer picture of actual costs.
Why acting now can save you money
With the UK landline switch off approaching, waiting too long can increase costs.
As demand rises, installation availability may become limited and prices may increase.
Openreach has already encouraged businesses to prepare early for the transition.
