Attendees over 16 but under 18 will need a guardian on site but they do not need to accompany them through the event. The event is NOT for children, there are scary scenes and adult content. Anyone accompanying younger participants must be over 18 and have a full-priced ticket.
My child is under 14 / has done lots of horror events before, can they attend?
No. The event is an intense scary experience and we do not allow children under 14 to attend.
Is the event indoors?
The event includes both indoor and outdoor sections. The majority of the event is set inside the Secret Nuclear Bunker. The waiting area and social pre-event are completely covered. There is an outside section at the start of the experience through the woods which can have uneven and muddy ground (don’t wear your best shoes!)
Will the actors touch me?
The actors will not touch you. We do not allow you to touch the actors or the set. We have a zero tolerance policy for violence towards scarers and staff.
Will I get blood /dirt on me?
Our location is rural and there is an outside section through some woods so it is likely you may get a little muddy on more rainy nights. Don’t wear your white trainers. Inside the experience it is possible that blood or makeup may transfer to your clothes from the set, so please dress appropriately.
Do I need to run?
You will not need to run, you may move through certain scenes quicker than others but running is not permitted.
How dark is it? Can I use my phone?
Some areas of the experience are dark. This is part of the experience, and the light level is never unsafe. Once your group begins the experience, phones must be put away and torches, phone torches and cameras are not allowed. If you have your phone out during the experience, we will take this as a sign that you want to leave, and staff will escort you out of the experience.
What happens if I am too scared?
If you are too scared please alert the scarer or staff who will radio staff to remove you from the area via our staff walkways, where you can wait for your group in the safety of the cafe or in a safe space until we are able to remove you without disrupting the event.
Please keep your phone away during the experience. Having your phone out at any point during the experience tells our team that you want to leave, and you will be taken out of the experience. If you leave the experience you will not be refunded.
How many people go through per group?
Groups are capped at a maximum of 6 people and may be made up of mixed parties. To guarantee a private group experience, book 6 tickets. If your private group has 8 people we can keep you together, but this may affect your scare experience.
Do you offer group discounts?
This year we are limiting numbers so unfortunately we are not offering any standard multi buy discounts.
Do carers get a discount?
Due to previous misuse of the carer ticket system, and to help make event check-in quicker and easier, all carer tickets now require pre-approval. Please see below for accessibility information.
Standard ticket charges apply to visitors with accessibility or additional support needs. However, we offer a reduced-rate carer ticket for guests who would be unable to attend the event without the support of a designated carer.
Carer tickets must be approved in advance, and we require a minimum of 21 days before your event date to process carer ticket applications. Applications received within 21 days of your visit will not be eligible.
To apply, please email info@thebunkerbelow.com with the subject ‘Carer Ticket’ and include suitable supporting documentation. Once your application has been approved, we will send you a discount code that can be used to add the reduced-rate carer ticket to your booking.
We can accept the following forms of supporting evidence:
A statement of Special Educational Needs from an LEA or NHS service. A letter from a medical professional on NHS-headed paper. A DLA or PIP award letter from the Department for Work and Pensions. Attendance Allowance documentation. Incapacity Benefit documentation. A National DID Card.
We do not accept carer cards, accessibility cards or nimbus cards as proof of eligibility.
Once you receive your code, please add the carer ticket to your booking alongside the other required admission tickets. A maximum of one reduced-rate carer ticket may be added per booking. Proof of eligibility may also be requested when you arrive.
Accessibility of the venue
Please be aware that The Bunker Below is not an accessible venue due to the nature and layout of the site and the event itself.
The experience requires you to be on your feet with no breaks for over 1 hour. The event takes place within a former underground bunker and includes stairs, narrow corridors, uneven surfaces, confined areas, low-light environments and sections where guests are required to move through the venue on foot. There is no step-free route through the full experience.
Wheelchairs cannot be accommodated through the event route, and some walking aids may also be unsuitable because of stairs, restricted spaces and uneven surfaces.
If you have mobility requirements or are unsure whether the event is suitable for you, please contact us before purchasing tickets so that we can provide further information about the route and its limitations.
Can I wear fancy dress?
Aren’t you scary enough?! Fancy dress is not allowed, and please don’t bring any accessories, props or fake weapons. Leave the scaring to us please.
Can I attend with any medical conditions or disabilities?
Please consult your GP before booking if you are pregnant or have a history of medical conditions that could be affected by a scare experience, including heart conditions, claustrophobia, photosensitive epilepsy, back disorders, diabetes, arthritis or asthma. The experience includes low lighting, flashing lights, loud sounds and confined spaces. We unfortunately are unable to cater for wheelchair users this year due to the stairs at the location.
I want to book with friends but the time-slot is sold out?
If the time slot your party is on is sold out, please book the slot immediately before or after. Let the check in team know and we will group you with your party.
I need to cancel / move my ticket?
All ticket sales are final and due to the nature of the event we are unable to move tickets. In extreme circumstances we may be able to move or refund tickets at our discretion, subject to a £10 admin fee for moving and a 20% admin fee (minimum £10) for refunds. Authorised moves and refunds can only be made up to 1 October 2026. After 1 October 2026, or from the moment you book if you book after that date, no tickets can be moved or refunded except in exceptional circumstances.
I’m going to be late what do I do?!
If you are late due to your friends not being able to manage their time, get new friends. If you have a genuine reason, we will be able to fit you into a later time slot if there is space. If there isn’t space you can wait in our social area until we are able to fit you in.
Can I film inside the experience?
You are welcome to take photos / videos inside the social area and during the queue. Once the experience has started, phones and cameras must be put away. The event is not meant to be lit up by camera lights, which will ruin the experience for yourself and others around you. Having your phone out during the experience tells our team that you want to leave, and you will be taken out of the experience.

Can I speak to someone?
