The Lancet nameplate was previously carried by a front-engined chassis, and later, in the 1950s and early 1960s, to the underfloor-engined Lancet UF.

[1][2] It was mainly used as the basis of a bus or coach, although some were bodied for other uses, mainly as mobile libraries.

At a time before the advent of low floor buses, when wheelchair access required the fitment of a chairlift, a few bus operators and councils bought Dennis Lancets with this feature.

Leicester Citybus and West Midlands Passenger Transport Executive had three and two respectively with Duple Dominant Bus bodywork.

[3] Other UK customers for the Lancet included Tillingbourne Bus Company, Merseyside PTE (with ten, the largest British fleet), Northern Scottish, Blackpool Transport, Portsmouth, Merthyr Tydfil and Taff-Ely.
