If you intend to provide food at your event you need to ensure that food is safe to eat. Check that any caterers are registered with their local Environmental Health Department. Alternatively you may wish to cater yourself; this can be done as long as it is done safely. This will involve:
Any event involving the public or any work activity will be subject to enforcement under The Health and Safety At Work etc Act 1974. You need to carry out a suitable risk assessment prior to the event to ensure that all hazards to safety are adequately controlled. If the event includes public entertainment you should check the following:
Washing and Toilet Facilities - Ensure that there are adequate toilet provisions on site for the number of people attending the event. If there are no toilets you will need to hire portable toilets and sinks.
Lighting - Ensure that there is adequate fixed lighting on walkways and around car parks to prevent slips and trips.
If the planned event is taking place on farmland you need to ensure that there is no access to livestock or machinery or dangerous areas through the installation of physical barriers and clear signage.
