The story

Dyno-Rod service was launched in 1963 by Jim Zockoll, in South London, and the business was based in Surbiton for many years. Zockoll was a flight engineer for Pan American, who spotted an opportunity whilst on a stopover in London: the hotel where he was staying was suffering drainage problems, had outdated repair equipment, and was taking too long on repairs. Zockoll flew back to the US to get his electro-mechanical drain-cleaning machine – equipment which was unknown in the UK – and cleared it in 20 minutes, giving birth to the company Dyno-Rod.

Dyno-Rod based its drain cleaning service on what were then new electromechanical techniques. After initial success, Dyno began granting franchise licences in 1965. There are currently twenty five Dyno franchisees in the United Kingdom. As the first non fast food franchised business in the United Kingdom, and the second franchised business of any kind there, Dyno-Rod played a prominent role in the formation of the British Franchise Association, of which it remains a full member.

Over time, the Dyno brand developed other associated businesses. Dyno-Secure was launched in 1987, to offer a range of locks and security services, while in 2001, Dyno-Plumbing offered a comprehensive plumbing service. Dyno Group was acquired by British Gas, a subsidiary of Centrica, in October 2004. Since then, Dyno franchisees have developed larger territories and operate multiple brands within the Dyno group.
