If we are to believe what we were originally told, all a pub has to do if they want entertainment is tick a specific box on the application form. As long as this is done at the first application, there should be no extra charge levied. The only reason a council can give for refusing an entertainments provision should be on the grounds of public order, ie they can't insist on building alterations.

On the other hand governments sometimes use "accidents" to force changes in the law - there was a classic one when Sunday lunchtime drinking hours were first increased (I certainly didn't complain).
Let's hope that the aforesaid box does appear on the application forms and that the rules haven't been changed.
