Harold Joseph Leak founded the seminal H. J. LEAK & Co Ltd in 1934. Originally based in London, England, LEAK was a brand that specialised in designing and manufacturing high-quality audio components. Harold Leak marketed himself as a ‘Sound Engineer – Technician’, and along with Ted Ashley, who joined the company in the late 1930s and who later became Chief Engineer for the company, LEAK became a market leader of affordable but high-performance home audio equipment... for decades upon decades!

The LEAK brand developed amplifier technology, loudspeakers, pickups and turntables, amongst many seminal products in a portfolio spanning the golden years of British audio innovation.

Pushed into obscurity and becoming a ‘cherished’ brand of yesteryear, LEAK became another example of a strong British audio brand that would be fondly remembered but no longer an option on the home audio market. After many years in a state of dormancy, LEAK was rescued by the IAG Group – one of the world premiere manufacturers of audio products and the owners of a plethora of classic British brands.

In 2020, the year that would mark Harold Joseph Leak’s 113th birthday and the 84th anniversary of the H.J. Leak & Co’s founding, IAG Group proudly announced the return of LEAK. Maintaining the art-deco inspired, classic-styled high-quality home audio format for the modern-day hi-fi enthusiast, LEAK was reborn and has continued to flourish.
