Every Pungra-certified instructor is required to hold public liability insurance specifically valid for fitness instruction — typically a minimum of £6 million cover. Ask to see the current certificate before the first session, and confirm the policy explicitly covers exercise instruction (not just dance or performance), since these are frequently different policies.
If you have your own venue insurance or safeguarding requirements (for example, a DBS check for sessions involving minors), confirm these separately — Pungra certification doesn't replace your own facility's compliance requirements.
