Hi. I.m going myself on the next few weeks and taking old sky box and dish. Will still pickup the satallite . I think. Just on the border but have got bigger dish. Should work ok

Most internet in italy at 15mbps and higher will work fine with a vpn.
Nordvpn, vilingvpn, unblockus, etc all ones that you can check

Also depending on your technical experience you can make a dns server and use dns addys from the UK.

I have nordvpn and its excellent - also its on offer at the moment.  You can use it on up to 6 devices and I got 3 years for 100 USD.   I got it more to protect me from hackers and the like, but can use UK sites if I change the settings.
