So last week we went down to help our friends at Elliot’s Bouncy Castle to raise money for a children’s cancer ward . We raised a whopping £7020. And we put on a huge selection of bouncy castles . Thankyou to everyone that came and everyone that was involved it was an amazing success and a wicked day. We are extremely proud and honoured to help our industry friends.

Team Big Bounce Theory.

We are proud to be helping out and providing some of our biggest inflatables to our friend Spencer at Elliott’s bouncy castle hire for the UK’s largest inflatable event.

If any of our customers can make the event and travel over it would be great to see you there.

Please share this far and wide .

It’s a real worthy cause and all proceeds are going directly to the children’s cancer ward .

Many thanks .

Just a few pictures from our annual testing day one. Thank goodness for the sunshine 🌞

An exhausting and expensive couple of days for us here behind the scenes making sure all of our castles get their yearly MOT!

When hiring a bouncy castle from any company - big or small - from marketplace, Instagram or even when hiring from just a friend or someone you know - every castle should have a valid annual test certificate and public liability insurance for your childrens safety ✌🏻
