Who we are
ICAS is a professional body for more than 20,000 world class business men and women who work in the UK and in more than 100 countries around the world. Our members have all achieved the internationally recognised and respected CA qualification (Chartered Accountant). We are an educator, examiner, regulator, and thought leader.
Almost two thirds of our working membership work in business; many leading some of the UK's and the world's great companies. The others work in accountancy practices ranging from the Big Four in the City to the small practitioner in rural areas of the country.
We currently have around 3,000 students striving to become the next generation of CAs under the tutelage of our expert staff and members. We regulate our members and their firms. We represent our members on a wide range of issues in accountancy, finance and business and seek to influence policy in the UK and globally, always acting in the public interest.
ICAS was created by Royal Charter in 1854.
