Alternatively host the gambling site offshore.
Careful - UK based developers may still need a developer license and operators may still need a personal/organisational license if they reside within the UK.
If you ever try to cash out your share of your sites takings and the bank reports it upstream or if you were to record it faithfully on your tax return, if you were discovered to be operating without proper licensing even through an offshore website, you could still face the same fines and jail time.
Rather than take legal advice from people on a forum - which let's be honest is why we ended up with so many sites before one of them even consulted the law, get a lawyer rather than thinking you or someone else with no legal experience whatsoever have found a loophole.
This is why you don't cash out your share of the BTC, you don't send it to a bank, and you leave it off your tax return. You SPEND it. You can buy cash right off of BitMit, or buy something which holds its value well for a short time and sell it.
