Historical Background
Dyno-Rod was founded in 1963 by Jim Zockoll, a former airline pilot, pioneering electromechanical drain-clearing in the UK. The company was the first non-fast-food franchise in the UK and played a prominent role in founding the British Franchise Association. British Gas acquired Dyno-Rod in October 2004 for £57.6 million.
