Bought by shipping giant P&O around the time of World War I it was sold in 1972 to an Australasian consortium and closed at the end of the twentieth century.

With 1 vessels attributed to it here, Union Company is the 492nd largest of the 965 operators in this directory that hold at least one ship on record, against a median of 2 across that group. That is a count of individually identified hulls, not the company’s published fleet size — the two are different measurements and both are shown above where available.
United Kingdom is the country of registration for 97 commercial operators in this directory, among which Union Company ranks 38th by ships on record. Between them those companies hold 260 vessels here. See every operator registered in United Kingdom.
