SKY TV Balloon Arch


"One of the main reasons we chose Castle Balloons was because of their biodegradable materials, however I was impressed by not only their sustainability commitments but also their creativity and enthusiasm in helping us create the perfect balloon arch for our corporate summer event. Chris took the time to understand exactly what we wanted and created the perfect arch, taking onboard our brand guidelines and preferences in the design"

Cancer Research Balloon Display

Cancer Research

"Castle Balloons provided balloons for Cancer Research UK’s London Marathon celebration event for all of their runners. The balloons looked incredible and it really elevated the venue; many amazing participants complemented all of the balloons throughout the venue. Chris and the team were amazing from start to finish and helped us plan our bespoke order which fitted perfectly in the space. We can’t wait to use them again in the future."

Scarlett O'Shea - Cancer Research UK


"Chris & the Castle Balloons team are now our go-to when we want to add the wow factor to a corporate event. Their creative ideas are delivered with a personal touch and real customer focus, working around our schedule to deliver amazing balloon architecture. I cannot recommend them highly enough!"

Mark Myles - Hilton Worldwide


"We had a more than brilliant experience with Castle Balloons - the balloon installations looked amazing and definitely added a wow factor to our events. Chris was also a pleasure to work with. Not only did he manage to help us out on such short notice but he was very accommodating - from getting the colours perfect to delivering to multiple venues. We will definitely be using Castle Balloons for our future events going forward and I highly recommend them for any corporate events or parties"

Bethany Hung - Wunderkind Corporation



"The team were incredibly helpful in taking some inspiration and turning it into reality for our event. Both the quality and service were fantastic, with our guests loving the balloon sculptures in particular. Highly recommended and would definitely use again in the future."
