Abacus was established more than 20 years ago by a group of Chartered Accountants to provide Professional Indemnity Insurance to the profession. Abacus is a not-for-profit company limited by guarantee and all board members are practising accountants. Importantly, our expertise enables us to help members prevent or minimise claims. Abacus has appointed Hiscock Insurance Brokers, professional indemnity insurance specialists, to administer the membership.
