Harold 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.

LEAK developed amplifier technology, loudspeakers, pickups, and turntables, amongst many seminal products in a portfolio spanning through the golden years of British audio innovation. LEAK became a market leader of affordable but high-performance home audio equipment... for decades upon decades.

In 1979 LEAK disappeared from the production lines. The brand was pushed into obscurity to become a mere memory and a ‘cherished’ brand of yesteryear. After many years in a state of dormancy, LEAK was rescued by the IAG Group – one of the world’s premier manufacturers of audio products and owner of a plethora of classic British brands.

In 2020, the year of Harold Joseph Leak’s 113th birthday and the year of H.J. Leak & Co’s 84th birthday, IAG Group proudly announced the return of LEAK! Maintaining the traditional art-deco inspired design and high-quality engineering foundations for the modern-day Hi-Fi enthusiast, LEAK is reborn.
