Yes. If you are employed, then you must ensure you are covered by the business insurance of the company that is employing you. If you are employed at an LTA registered venue, then you will have cover through their policy whilst working at that specific venue. However, if you are not formally employed (i.e. contracted/self-employed) then you would need your own Public Liability insurance to be insured – irrespective of your level of qualification. A cost-effective way to attain this cover would be to become LTA Accredited.
