Honda of the UK Manufacturing (informally HUM) is a subsidiary of the multinational automotive company Honda based in the United Kingdom. HUM operates a number of manufacturing plants at a site in Swindon, which include casting, engine assembly, pressing, welding, painting and car assembly activities. HUM employs around 3,400 people at the plants, which occupy a site covering around 370 acres. Honda has made a total investment of £1.38 billion in the Swindon plants. In 2008 the Swindon site produced 230,423 cars.
Honda's decision to invest in production facilities in Swindon came as a result of Honda's collaboration with Rover Group, which started in 1979. HUM was established in 1985 and production at the engine plant began in 1989. In 1992 production of the Honda Accord began in Swindon, and a second engine line was installed. In 1994 production of the Honda Civic began in Swindon. In August 2000 it was revealed that UK-manufactured Honda cars would be exported to Japan for the first time. HUM opened a second car assembly plant in Swindon in September 2001, creating an additional 200 jobs at the site. In December 2001 workers at the Swindon plants voted to form a union and be represented by the Amalgamated Engineering and Electrical Union. In 2002 production of the Honda Accord ended at Swindon, and in October of that year Ken Keir, the then managing director of HUM, stated that Honda would maintain vehicle production in the UK irrespective of whether or not it joined the Eurozone. In September 2006 it was announced that Honda would be recruiting an additional 700 workers for the Swindon plants, and raising production of vehicles at the site by 32% to 250,000. In February 2008 it was announced that Honda would be making an £80m investment in new production facilities at the Swindon site for the manufacture of plastic car parts and metal castings for engines. On 30 January 2009 it was announced that workers at the Swindon site would be laid off for four months until June 1, with full-pay for the first two months of the period and about half-pay for the remainder. In October 2009 HUM began production of the Honda Jazz.
