Liability insurance premiums for trampoline play centres have risen by more than 300% as insurers react to a steep rise in claims for the niche.

HIB Insurance Brokers Managing Director Michael Alexander told insuranceNEWS.com.au cover is coming down while excess and premiums are going up.

As many as eight underwriters have left the market in the past 12 months, leaving just two still providing cover. Up to 30 of the play centres have shut down in the same period as steep premium rises have been imposed.

“A few of the accidents that have occurred have been quite severe,” Mr Alexander said.
