It was mostly built as a single-decker bus, although some express coaches and a small number of double-decker buses were also produced.

[2][3] The later Falcon HC had a more orthodox continuous driveline, resembling that of the Seddon Pennine RU, the C (for continuous drive) denoted the Voith transmission close-coupled to the Gardner engine with a short propeller shaft taking drive into a straight Kirkstall spiral-bevel double-reduction rear axle.

National Bus Company subsidiary Alder Valley added one Dennis Falcon HC to its fleet in 1983, with Wadham Stringer bodywork of semi-coach specification.

Kowloon Motor Bus purchased 20 Duple Laser bodied coaches based on the Falcon HC chassis in 1985/86 for airport express services in Hong Kong.

Two examples with East Lancs bodywork went to Nottingham City Transport in 1982 as part of their evaluation of the various new generation double-decker buses then available.
