Ask to what standard are their products manufactured? Also get them to state that the products to the 2016 standard are unsuitable to use unless there is already upstream BS EN 60898 or BS EN 61009 RCD protection and is this restriction stated in their data sheets?
You might also ask if they have changed the design of their products from the 2009 standard to a lesser standard to only meet the 2016 standard or have they discovered that the products made to the 2009 standard were found to be un-suitable for additional protection?
