From VM's terms and conditions, I've highlighted the relevant text.
B. Virgin TV
1. We aim to offer a television service covering a wide range of
interests.
2. The television service is a variable TV service, so we don’t guarantee that we’ll provide any particular channel, or other content, or access to any third-party services. This means we may add, remove, change or interrupt (some, or all, of) the content and/or the television service from time to time. We may also have to make changes for reasons including (but not limited to) matters beyond our reasonable control, or where content or a service is made available to us by a third-party and they stop making them available to us or we gain or lose the right
to make the content or service available to you. Where this happens and, if appropriate, we will try to replace content with similar or equivalent content.
