There are two manufacturing plants in the UK representing a total investment in excess of £1.85 billion and currently 3,200 members are employed. The vehicle manufacturing plant is located at Burnaston in Derbyshire, the engine manufacturing plant is located at Deeside in North Wales.

The first car, a Carina E, drove off the Burnaston production line on 16 December 1992. The Avensis replaced the Carina E in 1997 and in 2003 the new generation Avensis was launched. In 1998 a second model, the Corolla, was introduced and in 2001 the new generation Corolla was launched. In 2007 production of the Auris, the new Toyota hatchback, started replacing the Corolla.  Production of the Auris Hybrid, the first full, mass-produced hybrid in Europe, began in 2010.

The processes at Burnaston include stamping, welding, painting, plastic mouldings and assembly and at Deeside machining, assembly and aluminium casting.
