Outstanding Service - From the ground up, the first initial phone call just being all too easy! Very helpful with the process, the easiest thing I've ever done, just little too efficient in that the delivery was placed and wrapped bound for our address. The courier was also all too happy to come down the drive way with the paper work. We were expecting to forward payment prior to delivery but your entire department was just all over it and far to quick. Thank you again!


A quick note to let you know that I posted the hole-saw back to you from Stoneville P.O. yesterday. It worked a treat, and the extra 40mm flange was most appreciated. Thank you once again for your generosity. It is gestures like these which give a company a good name. I'll be sure to contribute word-of-mouth recommendations for Coerco.

Just a note to comment on the good service from Coerco. Given the remote location of most of the deliveries from Coerco to our sites, it’s reasonably unusual for me to gain a first-hand view of your services. In this morning’s instance I was able to gain that view and wish to note that both the product and the delivery were first class. Your driver went far beyond what we would consider to be his duties and did so with a cheerful “no-problems” attitude – he was also an hour ahead of the predicted delivery time. The recipient of the tank was delighted and asked me to convey his thanks. Thanks and well done.


We strive to offer you convenience and flexibility to make it
even easier to choose Coerco as a supplier who delivers you
a quality product with service that won’t let you down.
