Kenning started his own
paraffin distribution business in 1901, distributing with a horse-drawn cart. This hire business continued to grow until, in 1970, the Kennings Group had a hire fleet of 5,000 vehicles. Three years later Kenning became the sole agency for
Morris Motors in Derbyshire. He became a long-term business associate and friend of another pioneer of widespread car ownership,
Lord Nuffield, the manufacturer of Morris cars. Alongside car agencies, he set up supporting businesses like forecourt petrol sales car servicing and car spares sales. Soon after that, he won the first agency granted by the truck-making firm
Dennis. In 1925, he began an association with
Reeve Burgess, a firm that made truck and bus bodies for mounting on lorry frames. Vehicle-building became another subsidiary business of the Kenning empire, producing milk floats in
Shrewsbury and road tankers in
Ossett. Another subsidiary business was car valeting and in 1939, sophisticated valeting equipment was installed at both the London and
Sheffield sites. Kenning became the first agents in the UK for
Lucas electrical components and the first for the Tyresoles system of remoulding tyres for longer life. He also set up the Midlands Counties Motor Finance Company. The subsidiary businesses around tyres started by Kenning were subsequently developed and became one of the largest suppliers of car, commercial and earth mover tyres in the country. Kennings also operated three tyre remoulding factories and marketed their own label, Fisk and John Bull, tyres. Kennings was registered as a private company with a capital of £100,000 in 1930; in 1939 it converted to a public company. ==Public service==
