I've discovered that it is possible for those of us that missed the window to claim for the above, can now apply to be registered. Problem is that you can't claim for 4 years. I know there was a route to claim for this on the basis of not being told about the scheme but a clerk told me that everyone was told as it was on our payslip. Well thats a really inaqequate form of communication so under what circumstances (if any) could you have your registration back dated? No one from our unit at the time told any of us about the scheme so we didn't register. Does anyone know of a way to get this registration backdated, or knows of anyone successful in doing this? Thanks for anyone who can help with this!
