PAT Testing for Bouncy Castle Blowers and Party Equipment

Whether PAT testing is a legal requirement, how often to test, and what we test on inspection day.

Every bouncy castle runs on a blower, and every blower runs on mains electricity, usually outdoors, on damp grass, with children close by. That's why the blower gets checked as closely as the castle.

The short answer: PAT testing itself isn't a legal requirement, but keeping your electrical equipment safe is. A PAT test is the most common way of showing you've done that.

Is PAT testing a legal requirement?

Not as such. The Electricity at Work Regulations 1989 require electrical equipment that could cause injury to be kept in a safe condition. HSE is clear that the law doesn't say how that has to be done, by whom, or how often, and that there's no legal requirement to test every year.

What it does mean is that you need some way of keeping your kit safe, and of showing you've done it. For hire equipment, HSE's guidance says the supplier should inspect and test it before each hire, and the person hiring it should make sure it stays safe while they have it.

For a hire operator, that usually means a careful check of the blower and lead every time they go out, backed up by a full PAT test at regular intervals. When a venue or school asks to see that your electrics are safe, a PAT test record is what they're expecting.

The three levels of checking

HSE describes three levels, and each one catches different problems:

  • User checks. A quick look before every use: plug, cable, casing and connections. Anyone using the kit can do this, and it catches most damage.
  • Formal visual inspection. A closer, recorded check by someone trained to do it, including taking the plug top off to look inside.
  • Combined inspection and testing. The full PAT test, carried out by a competent person with proper test equipment. This finds faults you can't see, such as a broken earth or breaking-down insulation.

HSE points out that a visual check is essential, because some faults can't be found by testing. A good PAT test always starts with a proper look.

How often should a blower be PAT tested?

There's no fixed interval in law. HSE and the IET's Code of Practice both say to set the interval by risk: how the equipment is used, where, and how hard it works.

A bouncy castle blower is at the hard-working end of that. It's carried in and out of vans, used outdoors, run for hours, and plugged into whatever supply the venue has. It needs checking more often than, say, a desk lamp in an office.

At a minimum, have your blowers and leads PAT tested every year, and do a user check every time they go out. If a blower has been dropped, got wet or tripped a supply, check it before it's used again.

What a PAT test covers on a blower

  • Visual inspection: the plug, fuse rating, cable grip, flex, casing, switch and the guard over the fan.
  • Earth continuity: for earthed (Class I) equipment, checking the earth path is sound.
  • Insulation resistance: checking the insulation hasn't broken down.
  • Leads: fly leads and extension leads get the same checks, plus a polarity check to make sure they're wired correctly.

Anything that fails is written up with what's wrong and what will put it right, the same as a fault on the castle.

Extension leads and cable reels

Leads get forgotten, but they take as much punishment as the blower. Check them as carefully, and include them in your PAT testing.

When you run a blower off a cable reel, unwind it fully. A reel left partly wound can overheat under load.

Labels and records

HSE says there's no legal requirement to label tested equipment or keep records. Both are still worth doing. A sticker lets anyone see at a glance that an item has been tested and when, and a record shows you have a system in place. It's what you'll be asked for if anything goes wrong.

Does new equipment need a PAT test?

No. HSE says new equipment should be supplied safe and doesn't need a formal PAT test before it's used. Give it a visual check to make sure it hasn't been damaged in transit, and bring it into your normal testing after that.

Daily blower checks

Alongside the electrics, HSE expects you to check the blower every day it's used:

  • the fan blades are clear of grass and debris
  • the non-return flap on the outlet works properly
  • the connection tube and blower are firmly attached to each other
  • you're using the right blower for that unit, as set out in the manual

Our safety checks page covers the rest of the daily checks.

What we test on inspection day

At every annual inspection, we PAT test one blower and its fly lead per castle as part of the inspection, at no extra cost. If you've got other electricals, such as extension leads, cable reels, fans, candy floss machines, speakers or lights, we can test those on the same visit. See what we inspect for the full list.

Extra items are £3 each. Our prices page has the details. Every item we test gets a PAT sticker and goes in your PDF report, so your electrics and your inflatables are covered by the same paperwork.
