The armorial of British universities is the collection of coats of arms of universities in the United Kingdom. Modern arms of universities began appearing in England around the middle of the 15th century, with Oxford's being possibly the oldest university arms in the world, being adopted around the end of the 14th century. The earliest granting of university arms was to King's College Cambridge by Henry VIII in 1449. Arms are still granted by the College of Arms to universities today, with new universities continuing to register arms, which has been seen as an attempt to appear more traditional or legitimate. As corporations, older university arms have historically been granted without a crest, however newer institutions use crests with mantling, including new colleges at older universities. The first crest granted to a university was to Leeds in 1905 while the first British university to be granted supporters was Sussex in 1962, although both Oxford and Cambridge have used angels as supporters and Cambridge has used the 'alma mater' emblem as a crest without these components being officially granted.

The Dymoke family of the Manor of Scrivelsby in the parish of Horncastle in Lincolnshire holds the feudal hereditary office of King's Champion. The functions of the Champion are to ride into Westminster Hall at the coronation banquet and challenge all comers who might impugn the King's title.

English heraldry is the form of coats of arms and other heraldic bearings and insignia used in England. It lies within the so-called Gallo-British tradition. Coats of arms in England are regulated and granted to individuals by the English kings of arms of the College of Arms. An individual's arms may also be borne ‘by courtesy' by members of the holder's nuclear family, subject to a system of cadency marks, to differentiate those displays from the arms of the original holder. The English heraldic style is exemplified in the arms of British royalty, and is reflected in the civic arms of cities and towns, as well as the noble arms of individuals in England. Royal orders in England, such as the Order of the Garter, also maintain notable heraldic bearings.

The Flag of Hong Kong between 1959 and 1997 was a Blue Ensign with the coat of arms of Hong Kong on a white disk. In Hong Kong, it is also nicknamed the Hong Kong flag (香港旗), British Hong Kong flag (英屬香港旗) or the Dragon and Lion flag (龍獅旗). In 1959, following a grant from the College of Arms and with the consent of Queen Elizabeth II, it was adopted as the flag of British Hong Kong. While the flag lost its official status following the 1 July 1997 transfer of sovereignty over Hong Kong, it resurfaced in the 2010s as a symbol of Hong Kong independence and protest against Chinese rule in Hong Kong.

The Heralds' Museum was a museum of heraldry run by the College of Arms Trust at the Tower of London during the 1980s. It was situated in the old Waterloo Barracks within the Tower.

The Lion and the Unicorn are symbols of the United Kingdom. They are, properly speaking, heraldic supporters appearing in the full royal coat of arms of the United Kingdom. The lion stands for England and the unicorn for Scotland. The combination therefore dates back to the 1603 accession of James I of England who was already James VI of Scotland. By extension, they have also been used in the arms of Hanover between 1837–1866 and the arms of Canada since 1921.

The Lion and Tusk was the main logo of the British South Africa Company (BSAC) and later as a state symbol of Rhodesia. The logo was used following the Company being set up during the scramble for Africa and was used as they governed Rhodesia. Following the company reliquishing control of Northern and Southern Rhodesia, the symbol fell out of favour with the Rhodesian public. However, following the Rhodesian republic being declared in 1970, the Lion and Tusk symbol was adopted as a state symbol to replace the British Empire's Royal crown until the establishment of Zimbabwe in 1980.

Heraldry in Wales has a tradition distinct from that of English and Scottish heraldry. There is evidence that heraldry was already being used in Wales by the middle of the thirteenth century; for instance, in Gwynedd, two sons of Llywelyn the Great are recorded as having borne coats of arms in this period. Following the integration of Wales into England in the fourteenth and fifteenth centuries, the Welsh heraldic tradition became merged into that of England.
