/ Wall of Shame


It is frustrating for NSI approved companies and the public at large, that there are companies in the UK who choose to advertise themselves as being approved by NSI, or infer that they are, when in fact this is not the case. In some instances, they use the NSI logo on their websites, vehicles, shop windows and paperwork etc, which misleads potential customers into believing they are approved by NSI.

Please be assured we investigate these issues and will publish names of companies who do not co-operate promptly to NSI requests to stop their misleading activities.

Logo - Screen - Gold - ColourOnly NSLogo - Print - NSI Silver - ColourI approved companies are entitled to display the NSI Gold or Silver logo depending on their NSI certification.  NSI approved companies can be found by searching in the NSI Approved Company Directory (see top right of this page).
