Founded in 2004, WatercoolingUK began at a time when custom watercooling was still niche, experimental, and driven by passionate PC enthusiasts. Back then, liquid cooling was all about pushing boundaries - achieving lower temperatures, near silent operation, and builds that simply looked incredible.

From day one, we've supported both grassroots innovators and globally recognised manufacturers. We were early adopters and champions of brands that have since become industry leaders, including XSPC, EKWB, and Hardware Labs. Over the years, we've helped shape the UK watercooling scene into the thriving market it is today.

What started as a small store quickly grew into a full-scale eCommerce operation, and with over 20 years of trading experience, we've continued to evolve alongside the industry. Today, as the UK's largest dedicated watercooling supplier, we offer the widest range of components, expert knowledge, and outstanding value - serving gamers, enthusiasts, professionals, and showcase builders alike.
