Overview
Consett Iron Company was a British iron and steel enterprise based in the Consett area of County Durham. It was formally registered on 4 April 1864 as the successor to the Derwent and Consett Iron Company, which itself followed the Derwent Iron Company founded in 1840 by local businessmen led by Jonathan Richardson. The business combined mineral extraction, ironmaking, steelmaking, engineering-related production and extensive industrial infrastructure. Its assets included coal mines, limestone quarries, coke ovens, blast furnaces, rolling mills, a foundry, a brickworks, workers’ housing and welfare facilities. The company’s early development was shaped by the exhaustion of the richest local ironstone. To maintain production, it supported improvements to railway connections and obtained ore from more distant sources, including the Cleveland Ironstone Formation from 1851. Financial difficulties became acute during the 1850s. The earlier enterprise owed the failed Northumberland and Durham District Bank almost £1 million by 1857, and an attempted transfer to a newly established successor company did not proceed. The 1864 company was established with £400,000 of capital and acquired an industrial base that included 18 blast furnaces, substantial land and a large estate of workers’ cottages. Under general manager William Jenkins, who served from 1869 to 1894, Consett achieved sustained profitability despite severe fluctuations in the iron and steel market. The company retained significant capital rather than distributing all available funds to shareholders, reducing its dependence on borrowing and helping it withstand downturns. Jenkins also supported schools, churches, a park, a hospital and other community facilities, reinforcing the company’s role as both industrial operator and dominant local institution. Consett repeatedly adapted its product mix to technological and market change. The spread of steel railway rails reduced demand for malleable iron rails and contributed to a production decline in the mid-1870s. The company shifted toward iron plates for shipbuilding, then invested in Siemens-Martin open-hearth steelmaking from the early 1880s. Its first Siemens furnaces entered production in 1883. From 1887 it produced steel angles, bars, rolled joists and girders, while the Angle Mills expanded the site’s capacity for shipbuilding materials. By the late nineteenth century the works were described as one of the world’s largest steel plate manufacturing sites. The company remained an important employer into the twentieth century, but limited space at Consett made modernization difficult. It did not adopt electrical power as rapidly as some competitors, and its equipment increasingly lagged behind newer facilities. During the Second World War it continued production using lower-quality ore and employed about 12,000 workers. Its coal mines were nationalized in 1947, while the remaining iron and steel operations were nationalized in 1951. The works were returned to private ownership in 1955, and a new steel plate mill opened in 1961 to serve shipbuilding. In 1967 the works were nationalized again and absorbed into the British Steel Corporation. By then the business faced declining British demand for iron, coal and shipbuilding, obsolete equipment, rising raw-material costs and insufficient capital investment. Consett Steel Works closed in 1980 after sustained political controversy, worker protests and demonstrations. Approximately 3,000 to 4,000 jobs disappeared, and local unemployment reached about 35 percent, roughly twice the national rate at the time. Most physical remains of the works were later removed. The site’s industrial memory is preserved in part by the Terra Novalis sculptures, made using materials associated with the former steelworks.
History
The industrial lineage of Consett Iron Company began in 1840, when local businessmen led by Jonathan Richardson established the Derwent Iron Company to quarry and smelt ironstone around Consett. The richest local ore was depleted relatively quickly, encouraging the company to improve railway connections and bring in supplies from further afield. From 1851 it obtained ore from the Cleveland Ironstone Formation near Eston in North Yorkshire. The earlier enterprise experienced serious financial problems. By 1857 it owed almost £1 million to the failed Northumberland and Durham District Bank. After an attempted sale to the Derwent and Consett Iron Company failed, a new Consett Iron Company Ltd was registered on 4 April 1864. The new company had £400,000 in capital, 18 blast furnaces, extensive land and a large housing estate for employees. It also controlled or operated collieries, quarries, coke ovens and other supporting facilities. William Jenkins became general manager in 1869 and remained in that role until 1894. His tenure is associated with the company’s first sustained period of profitability. Rather than distributing all profits, the company retained capital, allowing it to rely less heavily on loans during market downturns. Jenkins also expanded the company’s paternalist role in Consett through support for education, religion, healthcare, recreation and housing. By 1894 the company’s share of British steel production had reached a reported peak, although its share declined by 1910. Changing technology repeatedly forced the company to adjust. The increasing use of steel railway rails from the mid-1870s damaged demand for malleable iron and reduced production. Consett responded by moving toward iron plate for shipbuilding. It then began converting to steel plate production using the Siemens-Martin open-hearth process. The first Siemens furnaces were operating in 1883, and from 1887 the works produced angles, bars, joists and girders. The Angle Mills, established on a large industrial site, became a major center for steel plate and structural-section production. In the 1890s the company also operated a foundry at Crookhall and a brickworks, while its housing estate had expanded to approximately 2,700 cottages. After Jenkins’s period, the company’s technological position weakened. Consett’s constrained location limited the ability to rebuild the works, and the company did not move to electrical power as quickly as some competitors. Although it continued to invest in equipment during the nineteenth century, parts of the plant became obsolete. The business remained large: by the Second World War it employed approximately 12,000 workers and continued making iron and steel despite using lower-grade ore. State intervention transformed the company after the war. Its coal mines passed to the National Coal Board in 1947. The remaining iron and steel undertaking was nationalized in 1951, then denationalized in 1955. A new plate mill opened in 1961, supporting the shipbuilding market. In 1967 the works were nationalized again and became part of the British Steel Corporation. The final period was marked by structural decline. British Steel faced weak demand in traditional heavy industries, aging plant, rising coal and oil costs and inadequate capital investment. The Consett works operated below capacity while policy pressures encouraged the retention of employment. Closure in 1980 followed intense public debate and large demonstrations. Between 3,000 and 4,000 workers lost their jobs, and Consett’s unemployment rate rose to about 35 percent. Demolition removed nearly all of the physical works, although the Terra Novalis sculptures and local historical collections preserve elements of the site’s industrial legacy.
