Pilates insurance - UK

Hi All, I’m currently training to be a Pilates instructor in the UK. I require a certain number of hours teaching to qualify which means I need to get insurance.

I’ve contacted Hiscox and insure4sport but they don’t insure you if you don’t have a qualification.

Has anyone been through this and could advise? The companies I’ve contacted haven’t been very helpful.

Any support would be great, thanks!
