One of the most developed specialist insurance markets of any instructor profession, thanks to long-standing professional-body schemes alongside modern online insurers.
Decide first whether you're a member of a professional body – if so, the scheme route is usually excellent value with dance-specific wording. Either way, check three things: the venue-required liability limit (£5m is the safe default), how performances and competitions are treated, and personal accident cover if demonstrating is part of how you teach. Most teachers will pay under £100 a year for everything that matters.
