There is no legal time for lighting a bonfire. You can do it whenever you like. But it is a general courtesy toward the neighbours and surrounding to light a bonfire in the early morning or early evening. At this time, the neighbours are less likely to be affected by the smoke or fire.
The end of summer or autumn is a great time to do a bonfire, as there is an abundance of dried leaves and twigs in the garden.
Furthermore, ensure that you chose a still or less windy day so that the smoke doesn’t drift off far away than planned. Make sure the day is not damp either as smokes and fumes stick longer in the air than expected. Also, keep in mind that dry and hot weather also can be risky to do a bonfire as there is the possibility of wildfire.
Lastly, do not light a fire during the night as it may alert the fire service and neighbours. Also, ensure that neighbours are not putting their laundry for drying outside, as the clothes may get covered in soot or, worse, catch fire.
There could be limitations if you are planning on holding a bonfire in a public space, such as on the beach. Before getting your bonfire, consult with the landowner or the local council. As part of the Criminal Damage Act 1971, there are safety regulations; any fire considered a danger to persons or property would be a criminal offence, whether the damage is intentional or by reckless conduct. Assure that when you’re done with the bonfire, you clean up any mess. Otherwise, the landowner will begin banning them.
Your garden or backyard is a great place to have a bonfire. If you are arranging your Bonfire Night, be mindful that there are rules on the use of fireworks. You cannot do a bonfire between 11 pm, and 7 am. Besides, during some holidays and festivals (Bonfire Night, Chinese New Year, Diwali and New Year’s Eve), the time is stretched till1 am.
