About Koukan
Built for PC Enthusiasts.
Not Generic Resellers.
Koukan is a UK-registered company (company number available on request) founded in 2025. We operate under UK consumer protection laws including the Consumer Rights Act 2015 and the Electronic Commerce Regulations 2002. Our escrow payment system is provided in partnership with Stripe.

Koukan is the UK's dedicated marketplace for used PC components — designed from the ground up for people who actually know their hardware. Founded in 2025, Koukan is a UK-registered company operating under UK consumer protection laws. Every feature exists to make buying and selling faster, safer, and less stressful than anywhere else.
01
Escrow-Protected Payments
Your money is held securely until you confirm the item arrived as described. Sellers keep 100% of the listing price — buyers pay a small protection fee that covers escrow, tracked shipping labels, and UK dispute resolution.
02
Verified Parts Database
Listings are matched against our catalogue covering every major category — GPUs from NVIDIA and AMD, Intel and AMD processors, DDR4 and DDR5 memory, motherboards across all sockets, SSDs, power supplies, cases, and full builds. Accurate specs pulled automatically, not typed freehand.
03
Part Compatibility Checker
Before you buy, run it through the build checker. Add components to your saved build and Koukan flags conflicts automatically — wrong socket, mismatched memory type, insufficient power headroom. Stop Googling "is X compatible with Y" and get a straight answer on the listing page.
