With two bank holidays in May and the weather predicted to reach 25 degrees this weekend inflatables are expected to spring up across the country.
Safety expert at Ecclesiastical, Huw Andrews, told Premier they are not trying to over-inflate the importance of keeping children safe.
He said: "A lot of our customers - churches, schools - are looking at planning additional fundraising events and we just want people to do that safely.
"Bouncy castles are a great source of fun and entertainment for children and they are also a great opportunity to raise additional revenue at fundraising events but we want people to enjoy this equipment safely."
The advice includes using a reputable bouncy castle hire company with adequate Public Liability insurance (at least £2m) and ensuring the inflatable has been made according to British Standard (BS EN 14960) requirements.
Ecclesiastical's top ten tips for hiring and using a bouncy castle:
1. Use a reputable hire company, with adequate Public Liability insurance
2. If possible, ask the hire company to set up the equipment. If not, follow the instructions.
3. Check the inflatable has been manufactured to British Standard (BS EN 14960) requirements.
4. If the castle is over a year old, ask for proof that it has been properly tested
5. If an electrical blower is provided, check it has been inspected at least annually
6. Provide and maintain any additional equipment which might be required e.g. crowd barriers
7. Get the hiring company to supervise its use or make sure you have detailed instructions on how to do this
8. When castles are inflated, make sure there are always enough competent people supervising their use
9. Make sure the inflatable will not be used in the event of poor weather, particularly in high winds
10. Make sure any necessary checks are completed. Where any defects are identified, make sure these are rectified immediately, or keep children safe until this has been done.
