Not really enough information, do you have an address in the UK with a current Sky contract?
Is the house unoccupied when you are here, if so, just bring the viewing card with you when you come.
If you have internet here, then another good option is an Android TV box. I can get all UK terrestrial channels, plus loads of Sky channels (including F1) without a VPN.
There are also hundreds of TV series and programmes available, plus most of the latest films - latest Star wars is on there (although not very good quality)
There is also the option of `Sky Go' via internet using a VPN, if you do have a UK contract, or the option of TV via satellite / broadband via OTE https://www.cosmote.gr/fixed/en/consumer/products-services/tv
