FAQ's

Can we decorate the Party Den?
We want your celebration to be special, so you are welcome to decorate the Party Den while you are with us. We ask that all decorations are removed when your booking is over.
What time should I hire the party den for?
The Party Den is available to hire by the hour and can either be hired solely for celebrating after your activity or as a base for the duration of your event. If hiring for after your activity we recommend starting your hire for 15mins before your activity is due to finish.
Do all parents need to sign the disclaimer?
Participants aged under 18 years old will need an adult (18+) to sign our Risk Acknowledgement and Disclaimer. These digital disclaimers can be sent to children's parent/legal guardian by the lead booker using the disclaimer portal.
Do you supply food?
There are no catering facilities onsite. We recommend either bringing your own food or ordering Pizza to be delivered via Brentwood Dominoes. If you quote NUCLEAR they will give you up to 50% discount. The party organiser needs to make the order by phoning 01277 219999 the day before party.
Can I book a party if I have less than 10 guests?
We can host parties of any size. For smaller groups, please book onto one of our standard sessions. Your guests may receive their safety brief along side other guests before enjoying the same experience as they would as a larger group.
