Overview
Ross Group was a British food company founded in Grimsby in 1920 as Thomas Ross Ltd. It began as a family-owned fish merchant and expanded during the twentieth century into fishing, fish distribution, fish processing, frozen foods, poultry, fresh produce, retail food outlets, transport, vehicle businesses, shipbuilding and related industrial activities. Its development reflected the transformation of Grimsby from a major fishing port into a center for industrial food production and cold-chain distribution. The company’s early business was the purchase and sale of fish. By the late 1920s, Carl Ross had become chairman and managing director after his father’s retirement. During the 1930s, the company entered trawling and built a fleet through acquisitions and new vessels. Its position strengthened during and after the Second World War through investments in Trawlers Grimsby and other fishing companies, including the Queen Steam Fishing Company and GF Sleight. The group also acquired the Cochrane Shipyards of Selby, where vessels associated with the Ross fleet were constructed. At its peak, it controlled eight trawler fleets and operated one of Europe’s largest fishing fleets. Ross also helped establish the industrial supply base for frozen fish. It imported fish from Iceland and chartered vessels for large consignments of halibut from Norway at a time when imports of Icelandic fish were restricted. By the end of the 1950s, the business was landing roughly 100 million pounds of fish annually. In 1959, following a corporate reorganization, the Ross name became the principal brand for the group’s food products. During the 1950s and 1960s, Ross diversified well beyond fishing. Its portfolio included frozen and fresh foods, poultry, fruit and vegetables, potato products, food distribution, garden peas, retail fruit shops, motors, transport, chemicals and agricultural services. The group acquired Sterling Poultry in 1961 and introduced potato chips in 1962. Poultry became one of its most important activities, and the company was described as Europe’s largest chicken producer by 1962 after a series of acquisitions. Ross’s frozen-food activities placed it among the leading British brands alongside Birds Eye and Findus. The group’s expansion produced a broad but complex conglomerate. Trawling became strategically less attractive because it generated persistent losses and represented only a small proportion of group sales by the early 1960s. A major boardroom conflict led to Carl Ross’s departure in 1965. The fishing interests were subsequently combined with other fleets under British United Trawlers in 1969, while Imperial Tobacco gained control of the wider Ross Group in September of that year after offering £47.5 million. Ross continued to operate as a major British frozen-food and poultry name during the 1970s. On 16 March 1988, United Biscuits acquired the company for £335 million. Later corporate transactions separated and recombined parts of the former Ross portfolio. The Ross name survived particularly strongly in retail frozen fish, while the company’s former fishing and food-processing heritage became part of the industrial lineage that eventually led to Young’s Bluecrest, a major United Kingdom frozen-fish business. The historic Ross Group company itself is defunct, but its brand and physical legacy remain associated with British frozen fish, Grimsby’s docks and the Ross House headquarters building.
History
Ross Group was registered in Grimsby as Thomas Ross Ltd in 1920. The original business was a family-owned fish merchanting operation serving the British market. Its activities expanded geographically before the Second World War, with branches in Leeds, Leicester and Fleetwood in addition to the Grimsby base. In 1929, Carl Ross assumed the roles of chairman and managing director when his father retired, becoming the central figure in the company’s subsequent expansion. The move into fishing began in 1934 with a small fleet of four vessels. Ross then pursued an acquisition-led strategy, taking a major shareholding in Trawlers Grimsby in 1944 and adding further fleets, including the Queen Steam Fishing Company. In 1956, Carl Ross acquired GF Sleight, a business known for its experienced trawler skippers, and also acquired the Cochrane Shipyards of Selby. The shipyard built vessels for the group, including the Cat- and Bird-class trawlers that became associated with the Ross fleet. Other vessels connected with the group included Ross Tiger, Ross Leopard, Ross Jaguar, Ross Kashmir, Ross Revenge and Ross Cleveland. Several later entered maritime preservation, broadcasting or environmental histories unrelated to Ross’s original commercial operations. Ross expanded its role in fish supply and processing as well as catching fish. In the early 1950s, George Dawson was involved in the company’s attempts to import Icelandic fish. In 1954, Ross chartered the Norwegian steamer Norfrost to bring a large halibut consignment to Britain. These activities took place against regulatory restrictions and opposition from sections of the established British fish trade. By the end of the 1950s, the company was landing approximately 100 million pounds of fish annually. In March 1959, Trawlers Grimsby changed its name to Ross Group, and the Ross name became the principal food brand. The company’s diversification accelerated after the Second World War. It operated a Westwick, Norfolk factory producing fruit and vegetables, including garden peas, and acquired that operation outright in 1954. Ross bought Grimsby Motors in 1959, Sterling Poultry in 1961 and Waterworth Brothers, a fruit-shop business, in 1964. Potato chips were introduced in 1962. By the middle of the 1960s, the group’s activities ranged across poultry, frozen food, fish trawling and distribution, other fresh foods, motors, transport, vessel construction, chemicals, agricultural services and overseas operations. Poultry and frozen foods were among its largest businesses, and Ross became one of the leading British food producers of the period. The group also developed an international presence. In October 1965, it established Ross Diepvries in Breda, Netherlands, with Eurofrost NV, to manufacture and distribute products in the Dutch market. At home, Ross constructed a large headquarters in Grimsby in the mid-1960s. The eleven-storey building, later known as Ross House, became a prominent landmark near the docks and remains associated with the successor frozen-fish industry. Diversification did not eliminate the difficulties of the fishing business. By the early 1960s, trawling represented only about five percent of group sales and was a continuing source of losses. Ross had attempted to acquire Associated Fisheries in the 1960s, but its proposals were referred to the Monopolies Commission and rejected in 1966. After a bitter boardroom struggle, Carl Ross left the group in 1965. The fishing interests were later combined with Associated Fisheries through British United Trawlers in a transaction organized by the Industrial Reorganisation Corporation on 2 April 1969. Imperial Tobacco made an offer for Ross Group on 6 August 1969 and obtained control in September. Ross remained a significant participant in the British frozen-food and poultry markets during the 1970s, competing with Birds Eye and Findus. On 16 March 1988, United Biscuits acquired the company for £335 million. Subsequent takeovers, mergers, demergers and transfers divided the historic portfolio. The Ross name continued to be prominent in retail frozen fish, while parts of the company’s heritage eventually became connected with Young’s Bluecrest. The original Ross Group is no longer an operating company, but its commercial legacy survives through the Ross frozen-fish brand, successor businesses and the industrial history of Grimsby.

Frozen seafood
Ross frozen fish
Ross frozen fish was the company’s most enduring consumer-facing line.
