What Our Customers Say

We have had exceptional service from National Poly, They have supplied 70 rainwater tanks to date with a further 110 to go. The ordering process is without drama and after sales service exceptional. We have not had 1 problem with a tank.

Chris UnicombMaitland, NSW

This company can be proud of the service it provides from the initial enquiry and ordering of the water tanks to timing of the delivery. We were advised every step of the way as to the progress of our order. Payment was a simple matter of a direct credit for the deposit and paid remaining balance on delivery. If only all businesses were as easy to deal with.

Trish NiddrieGreen Point, NSW

I was very happy with all aspects of my dealings with National Poly Industries, I would especially like to thank our water tank delivery driver Rusty who was so friendly and professional.

Tracey KranholdStubbo, NSW

Right from the start I was courteously and intelligently handled by the lady on the phone. From then on, everything happened exactly as they said it would, with occasional progress notifications. National Poly should run courses telling others how to do business.
