It's officially illegal again to let off fireworks without telling the Fire and Rescue Service.
Each year, the public can only let off fireworks between midnight on the Friday at least two days before November 5, and midnight on the first Monday after Bonfire Night.
You can still hold displays, but need to let firefighters know first.
The restrictions run until December 28, when there's a five-day window to let off fireworks to celebrate New Year.
