I am a UK player, so will lose non-licensed casinos -- but, as the winter weather in the UK is not great, I will be spending maybe 3 months in warmer countries.
So if I was in Malta for instance - could I reregister with a casino using my hotel or apartment address in that country, and using paypal or neteller rather than my UK bank account? I suppose the question is -- who is not allowed to play - UK residents, regardless of where they are, or just anyone trying to play in the UK? (so would a malta resident be allowed to play while they were on holiday in the UK?)
I asked customer support - they have no idea - they do not know how the new laws work.
The new laws refer to "physically present in the UK", so in theory someone who comes here on holiday cannot play at their usual casino unless it has a UK license. The casino would also have to pay the tax on a non UK player who was physically present here when losing.
This looks pretty complicated, so I expect the casinos will adopt a simpler solution that is easier to administer. Foreign players would not be allowed to play whilst physically present in the UK, and in most cases, UK players would not be able to play at a non UK licensed casino when on holiday.
The exception might be if the UK player had a permanent second holiday home, such as their own Spanish villa, in which they spent several months per year. This would allow them to register with a permanent residential address in Spain (for example), rather than a temporary hotel room. They would also have to ensure that said player did not continue to play when back in the UK, so the complication vs the gain of a few weeks of revenue per year may mean that the casino decides it's not worth it, and bans players who are normally resident in the UK.
A player could easily get around this though if they DID have their own second home abroad, but the problems would come when it came to verification, because despite the foreign address and internet connection, their documents would still be UK ones. The only sure way would be for the UK player to acquire permanent (or dual) residency, and be issued with native documents instead of, or alongside, their UK ones. This is entirely permissible under EU freedom of movement of labour rules, in fact, anyone from the EU who spends more than a year here in the UK is REQUIRED to convert their foreign drivers licence into a UK one, and also to reregister any car they brought in with them with the DVLA, and to change over to UK issued plates.
You will have to approach casinos on a case by case basis, as there is unlikely to be a blanket industry policy. Front line CS will not have the answer, it will have to come from management and also legal advice from the casino's lawyers might be needed.
