For Parents Who Want Big Fun Indoors
If you’re a parent planning your child’s birthday this winter or an event organiser trying to keep kids entertained when the weather turns gloomy, this guide is for you. Many families struggle to find indoor spaces that can safely fit a bouncy castle - wondering whether the ceiling is high enough, the floor is suitable, or if the venue even allows inflatables at all. At Bizi Bouncers, we’ve spent 15 years helping parents across London and Essex host unforgettable indoor parties. From measuring hall heights to supplying fully insured, low-height inflatables, we know exactly what works (and what doesn’t) when it comes to indoor fun.
Why Indoor Bouncy Castle Parties Are a Winter Lifesaver
British weather is famously unpredictable - and the last thing any parent wants is a rain-soaked party. Indoor bouncy castle venues offer a safe, comfortable alternative that keeps the fun going regardless of the forecast.
-
Weather-proof celebrations: no cancellations due to rain, wind, or cold.
-
Easy supervision: enclosed spaces make it simple to keep an eye on the kids.
-
Flexible setups: indoor venues allow decorations, catering, and games alongside the inflatable.
-
Perfect for toddlers: soft-play corners and low-height castles make indoor events ideal for little ones.
What to Check Before You Book a Hall
1. Hall Size & Layout
Start by confirming the usable floor space after setting up tables and seating.
-
Small castles: need around 5 m × 5 m clear area.
-
Combo castles or slides: 7 m × 6 m minimum.
-
Leave at least 1 m clearance on every side for safety.
Pro Tip → Ask the hall manager for a floor plan or measure it yourself with tape before booking.
2. Ceiling Height
Ceiling height is the most common reason an inflatable doesn’t fit.
If you’re unsure, send us your hall details - Bizi Bouncers can advise which of our indoor-approved inflatables will fit safely.
3. Flooring & Surface Type
Smooth, even surfaces are safest.
-
Best: wooden, vinyl, or rubber flooring.
-
Avoid: thick carpet, tiles with gaps, or uneven concrete.
We always bring protective ground sheets to prevent scuffing or slipping.
4. Power Supply & Access
Each blower requires a standard 13 A plug socket. Ensure the hall has at least one outlet within 20 m of the setup area.
Check for easy access doors or ramps - inflatable units are heavy and need safe loading space.
5. Insurance & Permissions
Before paying a deposit, confirm the venue allows inflatables and that your hire company provides:
All of which come standard with every Bizi Bouncers hire.

Our “indoor-approved” castles are built under 10 ft tall, allowing them to fit into most community halls safely.
Combine your inflatable with foam shapes, ball pits, and ride-ons to create a complete indoor play zone.
Safety First
Every unit from Bizi Bouncers is inspected before and after setup. We ensure power cables are taped down, mats are positioned correctly, and all equipment meets BS EN 14960 safety standards.
Step-by-Step: How to Plan an Indoor Bouncy Castle Party

-
Confirm Insurance: Check both venue and hire company policies.
-
Book Your Inflatable: Choose a size and theme suited to your space.
-
Plan Setup & Takedown: Allow at least 30 minutes each side.
