ACOMS Applying for permission to fly in a restricted zone

Hi
Has anyone applied to the CAA to get permission to fly in a restricted zone, have tried to do it through the ACOMS site, but at the end it was asking me to upload a Authorisation form, well I don’t have that as yet, that is why I am asking for permission !, it is to fly near the Hartlepool Nuclear power station, they have told me to get permission from the CAA, not from them, have done this lots of times, but it seems now it is done through ACOMS, it was just via the CAA before !
