Koi Water Garden was established in 1992 by Andrew Richards and John Caress. Between them they had over 45 years Koi keeping experience including a period of time spent living on a Japanese Koi farm. John retired and sold his interest in the company in 2007. We have always prided ourselves on our superb reputation for fish health. All our Koi are quarantined for several months before sale – we believe Koi Water Garden is the only retail company in the UK with DEFRA approved quarantine facilities.
At Koi Water Garden we stock as many Japanese Koi as you’ll see anywhere in the UK. We are one of only a few companies who import Koi directly from Japan, most use wholesalers or European agents. We regularly visit Japan to select high grade and showgrade Koi for our customers. We are proud ofour reputation for having quality Koi at reasonable prices. Our Japanese Koi start from only £10 and go up to £5,000. Whatever you’re looking for the chances are we’ll have it amongst our stock of over 5000 fish.
From October 2008 Koi Water Garden has constructed the prementioned off-site quarantine and growing on facilities, to view koi at this facility it is by weekend appointment only. Please contact us if you wish to book an appointment. This site is divided in to eleven fish houses totalling 80 ponds. This has expanded during the years and Fish house 5-7 were constructed to expand our facility and increase the Capacity of the Quarantine site. In 2010 Koi Water Garden was forced to relocate from it’s original store in Lower Morden Lane and fortunately found a freehold site only 500 metres from the original store. This new store in Epsom Road, Sutton, was constructed in amazing 5 weeks by Andrew and his incredibly hard working team of directors and staff. Since then we constructed fish house 8 in 2020 for our jumbo Koi, Fish house 9 & 10 were completed in 2021. Fish house 11 will be completed in 2023 with 6 new ponds.
