Origins of Haden
Haden, a prominent engineering firm with a rich history, began in 1816 when brothers George and James established their engineering company in Trowbridge, Wiltshire. The partnership evolved over the years, with James retiring in 1855, leading to the formation of George Haden and Son, under George and George Nelson Haden.
By 1914, the company was under the direction of William Nelson Haden, J.P., and Charles Ingham Haden, having diversified its expertise to include: heating, ventilation, hot and cold-water supply, electric lighting and power plants, and even cooking and laundry plants. Their specialization in heat economy highlighted their innovative approach to engineering.

Wartime and interwar Haden
The company played a crucial role during both World Wars, converting its operations in 1915 to serve as a munition works. Following the wars, the firm transitioned into a private company in 1919, eventually becoming a public entity in 1921.

A significant milestone arrived in 1926 when Haden secured a contract to equip Carliol House in Newcastle with its innovative lower-pressure hot water panel system. This system utilized large thermal storage cylinders with electrical elements, strategically designed to draw power during off-peak hours, demonstrating an early commitment to energy efficiency.
Continuing expansion
The mid-20th century saw the firm continue to expand its services. By 1937, they were recognized as leading heating and ventilating engineers. By 1961, their offerings had grown. It included heating, air-conditioning, piping, and sanitary engineering, encompassing warm and cool air systems and industrial process services. At this point they were employing approximately 3,000 individuals.

Despite a dip in profits in the mid-1960s, the company quickly regained its footing. The late 1960s and early 1970s marked a period of strategic acquisitions and consolidation. In 1969, they acquired Troughton and Young to bolster their electrical contracting capabilities. This was followed by the consolidation of their electrical and mechanical engineering activities, including Troughton and Young, into a new subsidiary, Haden Young, in 1970. The same year saw the acquisition of Carrier Engineering Co., further broadening their expertise.
A time of change
Haden Young secured significant contracts, including one in 1971 for air conditioning, heating, and fire protection in an 18-story building. Reflecting these strategic expansions, the company officially changed its name to Haden Carrier in 1971.
The company’s journey under this name continued until 1986, when it became Haden Building Services Ltd. The company was subsequently sold to Balfour Beatty. In the 1990s, the company played a pivotal role in the construction of the Channel Tunnel, cementing its legacy in major infrastructure projects.
