Blackjack rules in the UK

Hi guys, I was wondering if anyone could give me some information about the playing conditions in UK casinos.

I know the rules used to be: 6 deck, S17, DAS, double 9 10 11 only, can't split 4s 5s 10s, no peek. But the wizardofodds suggests this may have recently changed to: double any first 2 cards, split any pairs (at Grosvenor casinos at least). Can anyone confirm this?

Also, are CSMs still about in the UK?

Thanks.
