List of post-nominal letters (United Kingdom)

This is a list of post-nominal letters used in the United Kingdom after a person's name in order to indicate their positions, qualifications, memberships, or other status. There are various established orders for giving these, e.g. from the Ministry of Justice, Debrett's and A & C Black's Titles and Forms of Address, which are generally in close agreement; this order is followed in the list.

When listing the honours and awards enjoyed by any person it is not customary to include the Order of St John, as this is a Royal Order and not a State Order, and so confers no precedence. The statutes of the order state (statute 32(2)) The letters specified ... may be used ... but admission or promotion to any Grade of the Order ... shall not confer any rank, style, title, dignity, appellation or social precedence whatsoever.

The Grades of the Order of St John are:

These are usually given in ascending order, and may be followed by an abbreviation denoting the awarding Institute.

(Only abbreviated forms shown; other institutions use full names (omitting "University of") in postnominals.
Institutions are sometimes given in parentheses)

Note 1: Use of Cantuar for Kent is rare and risks confusion with both Lambeth degrees and the University of Canterbury, NZ. The Latin name for Kent is Cantium (hence Cantiensis) which would give Cant (also used by the University of Canterbury, NZ); the University of Kent was originally the University of Kent at Canterbury.

Note 2: Awarded to undergraduates who receive a BEng or MEng degree from a programme within the City and Guilds College-Imperial College London.

Some examples are given here. See the list of Catholic religious institutes for a fuller listing of current Catholic orders (although note that that article gives American-style post-nominals with stops; when used in the UK the stops should be omitted).

According to Debrett's, these are placed directly after orders, decorations and medals (i.e. replacing university degrees). Unlike other degrees, medical qualifications are listed in descending order, doctorates first.
