You still have options on UK-licensed sites. I play the same stakes and mostly use Coral Casino – they run several Evolution and Playtech live blackjack tables that go down to £0.50 and £1, especially the “infinite” ones and some dedicated lower-limit rooms. Been a member forever because it’s a proper British brand (you’ve probably seen their shops), fully regulated, and the stream quality is stable even on average internet. Good place if you want to stretch a small deposit over a long session without pressure.
