Well you joined on a new customer offer so that can give large discounts and normally when those discounts expire bills jumped a lot, having increases on a yearly basis (apart from 2020 unless a discount expired) isn't going to add much glamour to those discount expiring.
Re: Increase in Contract Price - **please merge with existing price increase thread**
a month ago
For example: the ultimate oomph bundle is £79 a month for a new customer, however after the discounts expire it goes up to £139 per month,
But then consider that this bundle also contains discounts because certain services are taken together, for instance the sim card is discounted and the sim card also boosts the broadband product up a tier (350>500Mbps) for free,
Then there is the parts of the bundle that can increase independently such as Sky Sports and Cinema, and finally increases to services each year that can add a few quid here and there.
A good example of the above is when choosing the bundle as a new customer, if deselect that Sky Sports and Cinema collection, this is said to be worth £39.25 per month however the bundle cost then goes up to £107.00 during offer and then £144.00 after the discounts/offers expire.
So renegotiating contract (ideally yearly) is important to get best offers and keep the bills under control.
