Accreditations

We see third party accreditation as a way of providing customer confidence in our product and service and as an important part of our process of continuous improvement.

We make some very significant claims about the quality and performance of our products, but find that many inferior products are also trying to make similar claims. We hope that our product details do present the features and benefits of the product in an clear and informative way, but believe that it is only through third party testing and accreditations that the advantages of our products can be made clear.
