Office phone system prices depend on the kind of office phone system you choose. Hosted VoIP systems, which we’d recommend to SMBs, tend to cost between £6 and £40 per user, per month, depending on how advanced and featureful your package is.

Meanwhile, buying a self-hosted VoIP system can cost around £600 to £800 per employee, and analogue office phone system prices start at around £99 and reach over £900.

All that said, we know how difficult it can be to find the most accurate prices for your business, so read on and let us help you out. 

Hosted VoIP phone system prices

For a top hosted VoIP system, you’ll need to pay a few things:

  • A monthly subscription fee for the VoIP software package
  • An installation and configuration fee (if your provider doesn’t offer this for free)
  • Upfront costs for VoIP-compatible phones, also known as IP phones

Let’s break these prices down.

Hosted VoIP phone system software costs

Most VoIP phone software is charged on a per user, per month basis. And while some providers charge a set fee for the entire software package, others limit the features you can use depending on the price you pay.

While we’ve provided you with a rough guide below, it’s best to get in touch with individual suppliers to know what’s included in each of their packages. Our price comparison service makes it really easy for you to do this. Just provide us with a few details about your business, and we’ll send you the best suppliers for your requirements.

What's a hosted VoIP system?

A VoIP phone system is powered by the internet, making and taking phone calls over the internet instead of the traditional landline. A hosted VoIP phone system is one that’s securely hosted by your phone system provider on their own servers. You and your team will be able to access it via the cloud.

Below are examples of basic, standard, and premium packages from real phone system providers. We’ve included their prices and the key features available on these plans just to give you a glimpse of the price range and features you can expect in these types of packages. We’ve also rounded up the best phone systems for small businesses if you want to check out more options for basic plans.

Hosted VoIP installation costs

Sometimes, system providers charge a configuration and installation fee, which covers the cost of an engineer helping you to get everything set up. This fee is usually in the region of £250 for half a day.

That said, one of the perks of hosted VoIP is that it’s very easy to set up – often, it’s just a case of installing the right apps and connecting up any IP phones. So you’ll often find that hosted VoIP providers don’t charge any installation fees, because they expect you to do it yourself.

IP phone handset prices

The price of a VoIP phone system handset varies depending on the specification of the phone you need. Although all VoIP phones (also known as IP phones) will enable you to make full use of the features of your VoIP phone system, cheaper handsets won’t be as intuitive to use as more expensive models.

Below, we’ve provided you with some guideline prices:

Self-hosted VoIP phone systems cost

A self-hosted system means investing in a self-hosted PBX, and to purchase and configure a PBX isn’t cheap. Including the cost of the handsets, a self-hosted PBX phone system can cost in the region of £600 to £800 per employee.

You’ll also need to consider the cost of an internal or external tech team to install and configure the system. These prices will vary depending on the size of your business and the phone system features you need.

For example, Asterisk sells free software that can turn an office computer into a dedicated onsite telephone system host. The expense isn’t in the software, or even in the server/dedicated computer, it’s in the technical team that will need to build your telephone system from scratch and maintain it.

Analogue phone system prices

While BT plans to start switching off the landlines by 2025, analogue phone systems are still a decent short-term solution. And with many landline phones now coming with IP capabilities (the ability to connect to the internet), analogue phones need not be a wasted investment.

Of course, we’d always recommend VoIP phone systems instead. They’re cheaper, easier to install and scale, and come with many more call management and unified communications features.

8×8, for example, is a winning choice when choosing to migrate from an analogue system to VoIP. Our research shows that 8×8 is the best VoIP provider for UK businesses, scoring exceptionally well in a number of our research analysis categories, including features, scalability, security measures, and customer support. It receives perfect 5/5 scores for customer support, because it offers essential support tools on all its plans, including 24/7 live chat and phone support, and security, because it’s also compliant with data privacy laws such as HIPAA, FISMA, and ISO 27001.

But if an analogue phone system just makes more sense for you right now, let’s explore the prices.

PBX and key phone prices

For an analogue business phone system to offer optimum functionality, it’ll need either a PBX (private branch exchange) or a key phone.

The difference between a PBX and a key phone is that, while a PBX digitally sends a caller to the right handset via an auto-attendant, a key phone uses a light system to display when a line is busy, enabling the right person to pick up the call.

To give you an idea of costs:

  • A PBX that consists of two phone lines with six handsets costs around £160
  • A PBX with 16 lines and up to 64 handsets costs around £900+
  • A key phone that supports 16 handsets costs around £125–£250

It’s worth bearing in mind that key phones aren’t as scalable as a PBX, so spending more on the off-set may mean that you won’t have to pay as much in the future.

Multi-line phone system costs

If you’re thinking that your business doesn’t need that many phones, you can always look into a multi-line phone system.

These consist of a number of phone lines, plus two to 10 handsets, but don’t offer the same call handling features, such as an auto-attendant.

Panasonic offers four-handset multi-line phone systems from £109.99, and BT will usually install a new landline for around £140. This means that expanding to a two-line phone system with six handsets will cost you around £350.

Is VoIP cheaper than a landline?
A VoIP phone system is more affordable than a landline because it doesn’t require you to purchase dedicated hardware. All you need is an existing internet connection, and an internet-connected device such as a smartphone, IP phone, or computer, in any location. This is why a lot of businesses have transitioned from analogue to a cloud-based phone system. More importantly, you won’t be charged per phone call with VoIP, even with international calls, because VoIP calls are carried over the internet.
What is the cheapest way to have a landline?
One of the cheapest ways to have a landline is to get a provider that offers a landline service without broadband. BT and Direct Save Telecom are the only two providers in the UK that offer landline-only deals. The cheapest plan between the two providers is Direct Save Telecom’s UK’s Best Value Line Rental package, which is only £17.50 per month, while BT’s Pay As You Go plan costs £23.05 per month.
What is the cheapest telephone service?
There are only two major providers in the UK that offer landline-only home phone packages – BT and Direct Save Telecom, and between the two, Direct Save Telecom offers the cheapest telephone service. It’s the best value line rental package which costs £17.50 per month.
Can you still get a landline without the internet?
Yes, however, there are only two providers that offer landline-only deals: BT and Direct Save Telecom. Both offer three different kinds of landline-only plans whose rates range from £17.50 to £39.05 per month.
Is there a free VoIP service in the UK?
Yes, there are apps and software available that you can download for free that will allow you to maximise all kinds of communication services, such as calling, chatting, or even making a video call over the internet. Some of these applications are Facebook Messenger, Skype, Viber, and WhatsApp.
