Invoices that mean business
We listened to what our customers were saying about our invoices and took many of their suggestions on board so that they could be improved. We've made them easier to read, ensured that the details of our services and what they cost are clearer, and have added new information to ensure you always have the complete picture.
If you can't find the answers you're looking for using our self-help pages, please email our Customer Services team.

Details
This is where you’ll find a detailed breakdown of all the charges that relate to the products you buy from us as well as your billing details.
You won’t find individual voice calls itemised on our invoices because that would mean using up too much paper. We are working hard to be environmentally friendly, so if you want to check through an itemised list then you can do it online. To register for Colt Online please go to www.colt.net/online.
Please Note: Usage based voice and data services are displayed slightly differently to those that are non-usage based.
