It’s your party and you can go as late as you want to! Feel free to keep your CHEFIN party raging for as long as you like. We have no noise restrictions here, other than the standard council restrictions, and so we won’t tell you to shut up once it hits dark.
That said, we do ask that our guests kindly take into account any residential neighbours in the area surrounding your event venue. If the event might have a tendency to spill out onto the streets, please be aware that any noise you make might easily travel into the homes and bedrooms of people nearby. So it’s your party, but party with awareness!
