Professional Indemnity insurance is compulsory for all applicants and holders of current Certificates of Public Practice (CPP) and is an obligation for participating members of the Institute's liability capping scheme. While the Institute sets out minimum requirements (see R4 Appendix) members need to also consider (in discussion with their insurance brokers or other advisers) what is an adequate type and level of cover for their particular circumstances. It is the CPP holder's responsibility to ensure that the practice has a valid and binding PI insurance.
