Switchboard Phone System and Prices

This type of system uses the traditional phone lines. It is quite easy to set up as well as operate.

With a switchboard phone system, you will be able to have several physical lines.

The calls are usually connected and then distributed to relevant extensions through a Key phone or a Private Branch Exchange (PBX).

A key phone can handle a total of 16 extensions.

This will cost you between £100-£200.

When it comes to the PBX exchange unit, a system that has 2-6 extensions will cost around £130.

A system with 16-64 extensions, on the other hand, will cost around £700.

If what you have in mind is a desktop phone that uses the analogue system, you will have to part with around £30 to £100.

How Do You Find the Right Business Phone System?

The total amount you spend on a phone system for your business will depend on the size of your business.

How is that so?

Well, many businesses need daily telephone access to accomplish different tasks.

Understanding your business needs is essential if you want to have the right equipment in the appropriate volume.

With that in mind, take a look at the cost of large, medium and small phone systems.

Large Business Phone System Costing

A large business will need more equipment compared to medium or small business.

Some factors warrant these requirements such as:

  • The size of your staff
  • The roles and duties of your team
  • The frequency and amount of internal communications
  • Size of the office space

The table below indicates the cost estimates for a large business with conference functionality, six managers, 30 general staff, five customer service staff, and two receptionists.



Unit Cost

Total Unit Costs

Conference Phone 3 £100 £300
Phone for Executive Desk 6 £100 £600
Headset for Customer Service 5 £25 £125
Phone for Customer Service 5 £150 £750
Desk Phone for Reception 2 £250 £500
Desk Phone 30  £80 £2,400
Total Cost £4675

Next is a medium-sized business phone costing.

Medium-Sized Business Phone System Costing

A medium-sized building will need more equipment and functionality than a smaller one.

The table below reflects what a medium business ideally requires and indicates cost estimates for a conference phone, two managers, eight staff, two customer service staff, and a receptionist.



Unit Cost

Conference Phone 1 £100 £100

Desk Phone for Reception 1 £250 £250
Desk Phone 8 £80 £640
Total Cost £1540

From the above information, you can remove or add equipment as is necessary to scale costs.

For example, if you require only one customer service phone, you can remove the extra one and slightly lower the cost; similarly, if you need more desk phones, you can add another desk phone and factor in the price.

Lastly, let’s look at what you can expect to spend on a small-sized business phone system.

Small Business Phone System Costing

Even though a small business may have fewer people using the phone system, there are still some phone system features and equipment to choose from.

One of them is whether to use the VoIP system or to go the analogue way.
