As we never tire of explaining 🤮, WiFi is one of the two means by which your router can connect to your devices in your home, the other being via Ethernet cable 😛
But you mean, no doubt, that you want to cancel your Broadband, which brings the internet connection into your router.
Yes, you need to give notice. And if you have signed up for a year, rather than month to month, and the year is still running, whether your first year or a renewal year, you may have to pay Now an early termination fee 😢
There are exceptions though, such as if you are moving to a property where Now cannot provide you with broadband service.
Though if you are moving to a new broadband supplier, other than Virgin or one of the Altnets (new local full fibre suppliers), best to let them contact Now on your behalf for a smoother switchover.
Otherwise, read this article, and then get in touch with Now Broadband to discuss your options here:-

NB: you don’t have a Direct Debit with Now Broadband, you have a card-based CPA. It is very like a Direct Debit in most respects, except you have a few less protections with it, though that’s not the reason Now prefers CPAs; it’s more that CPAs are easier to set up and administer.
Set a Payment PIN on your account so that no-one but you can buy memberships on it.
Check your bank accounts monthly for any other unexpected payments to Now.
That way you can at least nip them in the bud, while you and Now figure out whose fault they are.
