Switching your TV to Sky from cable is easy and can be done with minimal disruption to your service. Whether you are new to digital TV, have Freeview, or are currently on cable, switch to Sky for over 400 channels of quality entertainment. You can choose one of our popular combinations or tailor-make one especially for you. If you are currently a cable TV customer and you want these services from Sky, you need an active BT line. Once you have booked Sky TV, call BT to get a phone line installed then cancel your cable TV and telephone contract. You can find detailed instructions and a sample letter to give to your cable provider here.
