I don't use my Broadband what is the cheapest deal as I pay £30 which increasing to £41.  I don't want to pay that so will probably cancel service

If you're not using it, the best deal would indeed be to cancel.

If your discounts have ended you will need to contact Sky to try to negotiate a new deal or potentially amend your package which will require another 24 month minimum term contract. Sky are not obliged to offer you another discount so if you’re offered something acceptable you need to agree to it there and then because if you decide to think about it the offer may no longer be available when you call back.

You can either call Sky or use the following link
