I’ve been buying from Kev for nearly 8 years now and have had well over 40 fish from him. The quality has always been outstanding, with exceptional development over time. EK is one of the few places where what you see is truly what you get - an honest, passionate business that genuinely cares.

Most impressed with Exclusively Koi. Recieved a Columbo pond test kit from them which was sealed and very well wrapped. On opening the inner tray that holds the bottles was very damaged. They offered to replace kit straight away. Customer service second to none. Thank you.

Great couple to do business with, very knowledgeable about their trade and patient with someone who knows very little! Would recommend and hope to use again.

We visited Exclusively koi for the first time today and I cannot praise Kevin enough. He has the highest customer service and is extremely personable and had time to talk to us and gave so much advice and information it was an absolute delight. He knows his subject and is driven by supplying the best quality not only in the fish but also in other stock items and food. The prices were excellent and he is very, very fair and customer oriented. His information was straightforward and honest and I highly recommend Exclusively koi to anyone. We will be going back and Kevin and the team will be our go-to for all our koi needs from now on.

I came across Exclusively Koi by complete chance as i was looking up koi auctions online and I was lucky enough to find Kevin's fantastic koi up for auction. I took part in some of those auctions and was fortunate enough to win some beautiful koi, Kevin has been very helpful throughout the entire process and was happy to keep the koi for me a bit longer to suit my needs. The koi got shipped out on my chosen day and they arrived the next day very safely packaged with plenty of air. Each koi is even more beautiful in person and they're bigger than i expected which is a very pleasant surprise. The koi are currently dealing with some stress from the long journey here but Kevin is very quick to answer any of my questions and offer advice to help the koi get settled in. Very grateful for the great customer service and i can definitely see myself emptying my entire bank account at Exclusively Koi. I decided to attend the national Koi show today, I was pleasantly surprised to see exclusively koi had a stall at the show! Dare I say they had some of the nicest koi for sale but even more importantly the prices were extremely reasonable! If I had the room I would have easily bought several koi. Massive thanks to the team, keep up the good work
