Call Charges & Line Rental

Call Charges

Tariffs designed specifically for business users


Sirus offer a range of highly competitive business call plans that will help you reduce costs and make significant savings on your monthly telecoms expenditure.

Our packages are designed specifically for business users with tariffs bespoke to meet your individual usage levels. We will work closely with your business to analyse your call patterns and current level of usage so that we can design a tailored call plan that fits your specific needs.

Save up to 40% on Your Call Costs

Our business tariffs are highly competitive and will allow you to cut your monthly costs significantly by making major savings on all your local, national and international calls (fixed lines, mobile and non-geographic numbers e.g. 08).

There is no need to change your phone number and all calls are routed automatically, so there is no need to enter a prefix before you dial. Consolidate Services and Control Costs with One Simple Bill.

You can also opt to transfer your line rental to Sirus and make further saving for your business so that you receive one bill for both line rental and call charges.

If you are using a variety of suppliers controlling your telecoms expenses can be a complicated and time consuming process. We can combine services and provide one simple and easy to understand monthly bill. This will provide a detailed breakdown of all your telecoms expenditure allowing you to keep a tighter control on your finances.

Line Rental

A solution that is personalised to your needs

Whether your business is a small office or a multi-site organisation we can help you make substantial savings on your telephone line rental costs with our range of business grade communication products. We are able to transfer existing services and install new phone lines for any type of analogue, digital and VoIP enabled lines covering all your voice and data communication needs.

Your Business Phone Line Options

There are 3 main options for your business phone lines as follows:

Analogue Lines – Single / Multiple Lines
Digital Lines – ISDN2e / ISDN30e

We understand that telecoms can be a complicated affair filled with a mine field of acronyms. We will make the process as simple as possible by consolidating your line rental services and providing a solution that is personalised to meet the individual needs of your business.
