The Sky setup will work when they're back in the UK - They'll just need a dish and cabling.

The relevant question is how do they subscribe to Sky in France? Sky do not supply to customers outside of the UK so your parent's subscription will not be associated with their address in France. If they've used a company to sort out their subscription for them they're probably paying over the odds and it would be worth cancelling and re-subscribing with Sky directly. If they're using a friend's address to pretend to be in the UK then they just need to tell Sky that they are moving. Both options will get them a new dish installed...
