You do not need a licence at all, you need to provide a Temporary Event NOTICE. This means you have the right to have an event and provide licensable activities, including the sale of alcohol, without permission. However, you must provide two notices at least 10 WORKING DAYS before the event (not counting the day the notice is given or the day the event is held). One notice goes to the police and the other goies to the local authority. The LA will acknowledge receipt of the notice and, unless the police raise an objection on crime and disorder grounds within 48 hours, you can go ahead. If they do, the matter goes to a hearing where the objection will be considered together with whatever you have to say. You will then get a decision. If your receive a counter notice following the hearing, or because the number of such events at the premises concerned exceeds the maximum allowed (12 in a year/15 days in a year) the sales will be illegal and the pubishment is quite severe. However, if you don't receive a counter notice, you may go ahead and your receipted notice counts as your authority to make the sales. This will cost �21. Check your council's website for a downloadable form as many publish them in this way togther with full instructions on what to do.
