I am paying £30 for full fibre 100 and £20 for line rental. I do not use landline at all.
The current broadband only deal is £34.99 for full fibre 100. Does it include line rental?
You will pay for line rental regardless of which package you are on. It is to cover the cost of the infrastructure that delivers broadband to your property. All packages include that cost in the price.
What you can do is not have a landline phone or move onto a pay as you go call package if you rarely use the phone.
They normally build line rental into the price now to avoid confusion but check the wording on the advertisement where you saw the price. If it's an upgrade it'll say.
If you want to be sure, speak with customer service/sales.
