How to organise an event: from first idea to final sign-off

Most event-planning guides start with the concept and the budget. That is correct, but it hides the real constraint, which is that four separate bodies each have to say yes and none of them talks to the others by default. The landowner controls the ground. The licensing authority handles alcohol, regulated entertainment and late-night refreshment under the Licensing Act 2003. The highway authority controls any closure, diversion or sign on the public road. Environmental health, the fire service and the police each carry their own statutory powers over noise, safety and public order.

The council's Safety Advisory Group is where those strands get pulled together, and it is the part organisers most often misread. A SAG is non-statutory. It has no power to approve an event and no power to ban one, and it does not take on any of your responsibilities as organiser. What it does is put every agency in the same room, which means an unanswered comment in a SAG meeting tends to reappear later as a formal objection from a body that can act on it.

Because the clocks run in parallel and none of them is short, work backwards from the longest one instead of forwards from today. A temporary traffic regulation order for a road closure typically needs a minimum of 12 weeks with most highway authorities, since the order has to be advertised and consulted on. A premises licence carries a 28 day consultation. Councils commonly want event notification 6 weeks ahead below 500 people and 6 months or more above 1,000. If your event is 4 months away, the drawings are not a spring project, they are a next-fortnight project.

A temporary event notice is the light-touch route under the Licensing Act 2003 in England and Wales. It covers licensable activities at a site that is not already licensed for them: selling alcohol, providing regulated entertainment such as live or recorded music, and serving hot food or drink between 11pm and 5am. You give the notice to the council, and you copy it to the police and to environmental health.

The limits are strict and they are where events come unstuck. Fewer than 500 people on site at any one time, crew and traders included. No longer than 168 hours, which is 7 days. The fee is £21. A single premises can carry up to 15 notices a year up to a combined 21 days, and an individual can give 5 a year, rising to 50 if they hold a personal licence.

Timing matters more than the form. A standard TEN needs at least 10 clear working days before the event, and clear means the day it arrives, the day of the event, weekends and bank holidays all drop out of the count. A late TEN, given 5 to 9 working days ahead, is possible but fragile: if the police or environmental health object to a late notice, it is simply invalid and the activity cannot go ahead, with no hearing to argue your case.

Push past 499 people, run longer than a week, or use the same field every month and you are into premises licence territory instead. That application runs a 28 day consultation during which responsible authorities and members of the public can make representations, and it must be accompanied by a scale plan of the premises, normally drawn at 1:100 unless the licensing team agrees otherwise in writing. Scotland has no TEN at all: unlicensed premises apply to the licensing board for an occasional licence, capped at 14 days, and boards in practice want the application around 28 days out. Northern Ireland runs a different system again.

There is no statutory template for an event management plan. Each council publishes its own, so download the one your council uses rather than a generic version, but the contents are consistent enough to prepare in advance: event overview and capacity, site plan, crowd management, stewarding and SIA-licensed security, traffic management and parking, medical and first aid cover, fire safety and evacuation, noise management, waste and welfare, communications, and the procedure for a major incident or a show stop.

The annexes are where an application stands or falls. Expect to attach a site plan drawn to scale, your general and fire risk assessments, a traffic management plan for anything touching the highway, supplier documents including insurance and structural calculations, and evidence of public liability cover. Councils commonly set that cover at £5 million and raise it for higher-risk activity. Treat the plan as a live document: SAGs work through successive drafts and usually want the final version at least a week before the event.

The site plan is the annex that comes back most often. A reviewer has to be able to measure on it: is the fire lane still 4.5 metres wide once the food traders are in, is the emergency exit route clear, does the crowd figure you quoted actually fit the square metres you have drawn. A sketch without a scale cannot answer any of those questions, so it gets returned, and on a fixed event date that lost fortnight is the expensive part.

One practical point: supply the plan as a PDF at a fixed paper size with the scale printed on it, not as a screenshot pasted into a document. Councils working with an assessment module can then measure and mark up directly on the drawing, which shortens the review considerably.
