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 18 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

By the way, we're customers here.
