The order consists of the Sovereign, plus no more than 65 Companions of Honour with, originally, a quota of 45 members for the United Kingdom, 7 for Australia, 2 for New Zealand and 11 for other countries. Additionally, foreigners may be added as "honorary members". The order confers no knighthood or other status, but recipients of this one-class order are entitled to use the post-nominal letters "CH".
The insignia of the Order consists of an oval medallion with an oak tree, a shield with the royal arms hanging from one branch, and on the left a mounted knight in armour. The badge's clear blue border bears the motto IN ACTION FAITHFUL AND IN HONOUR CLEAR (Alexander Pope's description (in iambic pentameter) in his Epistle to Mr Addison of James Craggs, later used on Craggs' monument in Westminster Abbey) in gold letters, and the oval is surmounted by an imperial crown. Men wear the badge on a ribbon (red with golden border threads) around their necks, and women on a bow at the left shoulder.
