Not sure if equity have changed their policy yet so it actually covers fire performers properly, you may need to request a specific change to the policy - I'm not 100% but believe there is a clause that means your not covered if props are not kept in a sealed metal container - tricky for staves.
Towergate have just sent me a letter to say as an old customer please be advised we can offer cover from any day now not just september to september.
