Gimmick-Free Call Charges

Standard call charges to UK landlines and mobile networks


All call charges are shown as pence per minute, ex VAT.


At CIX we are committed to supplying our customers with not only good value phone solutions, but ensuring that our pricing and services are as clear and transparent as possible. Our industry is filled with gimmicks, catches, small print and commitments. We prefer to offer a simplistic view of telecoms with per second billing of call charges and fully itemised billing. Customers can make significant savings compared to their existing suppliers by not paying for "free" minutes unused, and if you are not completely satisfied we provide you with the flexibility of minimal contract periods.


Per Second Billing
Per Second Billing

Unlike some of our competitors we will only bill you for the time you spend on the call. This is done by billing on a per second basis rather than rounding calls to the nearest whole minute. It is one of many ways we want to ensure our billing is as clear and simple as possible.

Free Fully Itemised Billing
Free Fully Itemised Billing

All your phone calls are logged in our itemised billing pages accessible through the control panel. We show you all calls made, not just those that exceed a certain call spend. These are updated every 24 hours. Graphical statistics and call interrogation software are also supplied as standard.


No Minimum Charge
No Minimum Charge

In June 2012 the average call length of our business customer call minutes was just over 2 minutes. By not paying a minimum call charge you can easily save up to 35% on your phone bill before you consider the saving on our low call costs. If a call lasts 10 seconds, you are billed for 10 seconds.

No Minimum Call Spend
No Minimum Call Spend

We do not force any of our customers to reach minimum call commitments. This means that both residential and business talk customers can benefit from our low cost calls no matter how large or small your phone bill is. Businesses may not realise that penalty charges maybe being applied to their bills owing to failed spend commitments, but not with us!


No Call Connection Fee
No Call Connection Fee

With the exception of some calls that attract connection charges (eg Directory Enquiries) we don't apply connection charges. This can make a substantial impact to a phone bill when you consider BT Retail charge 15 pence* to make the connection (*19 April 2013 connection charge).

Tier 1 Carriers
Tier 1 Carriers

No compromises are made to the quality of calls. All calls are connected via Tier 1 carriers ensuring that no matter where your end user dials in the world, the call is of high quality and reliable. The call quality will be to the same standard as you receive from other large telecom providers in the UK.
