It is a few months before my sky TV contact runs out, but can I I renew my sky TV contact for another 18 mouths now

Yes, you can typically renew your Sky TV contract a few months before it ends. Sky often allows customers to discuss and renew their contracts in advance. It's a good idea to reach out to Sky's customer service or check your Sky account online for specific options available to you. They might also offer different packages or promotions for the renewal period, so it’s worth inquiring about those as well.
