Sorry, Jennyjoan. I'm lost. (I don't have Sky).
If it's a service that's being 'offered', rather than a particular programme, it could be that there's an app available for your box that's not pre-installed by default. For example, some devices might have BBC iPlayer, ITV Hub, etc pre-installed but not have UKTV play on them. (If that's the case, UKTV Play could be 'offered' for download, so that it can then be used to access relevant programme content). That's just a guess though!
