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 show grade Koi for our customers. We are proud of our reputation for having quality Koi at reasonable prices. Our Japanese Koi start from only £10 and go up to £7000. Whatever you’re looking for the chances are we’ll have it amongst our stock of over 5000 fish.

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.

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 four fish houses totalling 30 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 2020 Completed the construction of our 8th Fish house, at our Quarantine centre, Making it possibly the Largest in the UK! The Quarantine centre has the highest DEFRA quarantine rating in the UK due to our state of the art design and procedures.

In 2007 a sister company Koi & Water Gardens Limited was formed by the outside element of the business has proved successful in difficult times mainly through our beliefs of providing customers with a high quality professional service, unequalled by our rivals.
