‘Pay’ channels are available from other companies in addition to the Freeview service. The core idea behind Freeview is that all the channels are free and there’s only a one-off payment for the equipment and no contract.
Other companies offer extra content such as sport, movies, entertainment, children’s programmes etc. on a subscription or pay per view basis and you’ll still receive the Freeview channels for free. These include Netflix, Now TV and Amazon Prime which offer extra programming through TVs or boxes connected to the internet. You will need the right equipment to receive their channels and services. These companies are run separately to Freeview, which remains a not-for-profit organisation committed to providing free digital TV.
