Yes there will be some changes with Brexit of course. A few years ago some rules were changed so that you could watch TV apps from other EU states anywhere else in the EU, this will now go for Britain. A woman in a pub in Wales won a case in the EU courts when she was showing football via a Greek satellite in her pub. This changed things massively so that if you were in Spain watching iPlayer via a VPN, this would now be OK. But now this will change.
This is not really the top of the list of priorities for expats as health really should be now that the EU healthcard is invalid for them if they are British.
