Excepting the Association of Certified Public Accountants, each of the above bodies admits members only after passing examinations and undergoing a period of relevant work experience. Once admitted, members are expected to comply with ethical guidelines and gain appropriate professional experience.

Chartered, Chartered Certified, Chartered Public Finance, and International Accountants engaging in practice (i.e. selling services to the public rather than acting as an employee) must gain a "practising certificate" by meeting further requirements such as purchasing adequate insurance and undergoing inspections.

The ICAEW, ICAS, ICAI, ACCA, AIA and CIPFA are six statutory RQB Qualification Bodies in the UK. A member of one them may also become a Registered Auditor in accordance with the Companies Act, providing they can demonstrate the necessary professional ability in that area and submit to regular inspection. It is illegal for any individual or firm that is not a Registered Auditor to perform a company audit.

All six RQBs are listed under EU mutual recognition directives to practise in 27 EU member states and individually entered into agreement with the Hong Kong Institute of Certified Public Accountants (HKICPA).

Further restrictions apply to accountants who carry out insolvency work.

In addition to the bodies above, technical qualifications are offered by the Association of Accounting Technicians, ACCA and AIA, which are respectively called AAT Technician, CAT (Certified Accounting Technician) and IAT (International Accounting Technician).
