Our Story

OiOi Koi is owned by Barry Jeffery who has 10 years of experience in Koi keeping and growing. Barry’s interest in koi started at a very young age as he grew up helping his dad with pond builds and landscaping. His interest in koi was ignited when his dad received Custard, a beautiful Yamabuki Ogon from a close family friend and koi dealer.

To crystalize the years of knowledge and experience gained, Barry is qualified in water filtration, fish biology, fish health, pond construction and water quality. He also holds a City & Guilds Accredited OATA Foundation certificate. OiOi Koi is a licensed dealer for Animal Activity by Colchester Council, and is rated 5*.

Our aim is to be able to offer good value to all of our clients, with honest and knowledgeable advice – pond enthusiast to pond enthusiast, koi keeper, to koi keeper.

We want to make pond and koi keeping simple, so others can enjoy the amazing benefits having a pond in your life can bring.
