How much can VoIP phones really save your business?
22nd May 2026
As the clock is ticking towards the analogue PSTN switch off, it’s time to look at how much Voice over Internet Protocol (VoIP) phone systems can really save your business.
In today’s climate of increasing utility costs, many businesses are looking for practical solutions to lower them without compromising the service quality. While traditional phone systems proved to be reliable in the past, their limited features, maintenance costs and line rental charges, are no longer competitive against Voice over Internet Protocol technology.
While savings with VoIP depend on individual business size, usage and setup, let’s take a look at how much money organisations can realistically save.
Why should businesses make the switch to VoIP?
On a global scale, more than half of startup businesses have already made the switch to VoIP – a modern technology that allows phone calls to be made via broadband internet connection.
Yet surprisingly, established businesses have been slower to respond to changing technologies and have retained their landlines – with 62% of businesses still using traditional copper-based phone systems in 2025. But with the PSTN switch off just around the corner, those organisations yet to make the move have good reason to move with the times – and not just because their legacy connections will be cut off in 2027.
Cost effectiveness is one of the primary benefits of business VoIP. In fact, in some cases, moving to the digital system can cut phone bills by as much as 75%. Scalability is yet another VoIP benefit, allowing organisations to add or remove phone lines with minimal effort. It supports remote working, has plenty of advanced features, improves call quality and supports sustainability efforts across the business.
Where businesses lose money with traditional phone systems
While there was a time when analogue phone lines were the first choice, as the world moves towards digitalisation more and more each day, traditional business telephony becomes unfeasible in a modern setting.
Maintenance costs can prove to be expensive for analogue phone systems because replacement parts for older phones are often discontinued, scarce or costly to obtain.
Additionally, more than 40% of the UK’s workforce are now working remotely and so traditional phone systems plugged into an office desk simply cannot support this.
How business VoIP reduces communication costs
It could be said that what analogue PSTN (Public Switched Telephone Network) lacks, VoIP makes up for. For example, traditional PSTN services require a separate line in rental charges for each phone line. In comparison, VoIP operates through an existing broadband network. This reduces subscription costs.
Moreover, it significantly reduces national and international call charges, which depend on each business VoIP provider but, in most cases, are very minimal.
Because VoIP is a cloud-based business telephony system, it doesn’t require expensive on-site hardware and infrastructure, proving savings once again. Moreover, maintenance and upgrade costs are usually handled by the provider, which reduces long-term expenses.
If you’re a startup business, VoIP might be especially appealing to your organisation because it makes it possible to rapidly scale up user numbers through simple software rather than through the installation of physical lines. Inevitably this saves both time and money.
Lastly, VoIP comes with many features as part of the package, including video conferencing, call forwarding and mobile integrations. These additions are not only beneficial to have in a modern business but they also remove the need for separate communication services.
How much can businesses actually save?
While the savings that are made by moving to VoIP can vary significantly dependent on the individual circumstances, research suggests that it can save in the region of 50% on phone contracts when taking into account reduced setup costs and reductions in hardware.
Of course, savings depend on each individual company, however 83% of those who have already made the switch reported cost savings after moving to VoIP. 92% of small businesses reportedly achieved better security results and 59% of them also reported productivity benefits.
It is safe to say that switching to VoIP is something that can greatly benefit businesses of all sizes and not only in terms of the monetary savings but also in terms of time-efficiency.
