Employers Liability is a compulsory form of cover if you have employees, the law requires you to hold Employers Liability cover for an indemnity limit of at least £5m. Public Liability is not compulsory by law, so no certificate is issued.
Committee members and volunteers come under the definition of employees and would be covered by the Employers Liability section. The insurance certificate must either be displayed where it can be seen by the employees and volunteers or made easily available to them in electronic format.
