Our OS provisioning image works perfectly fine for all staff on our standard laptops but on a new model of laptop, no one with support permissions can image this laptop however admins can, for some reason the template doesn’t start for them but if I specify my credentials as admin, it works first time. Any ideas?
It is probably your scopes. Likely if you look in each scope that the support staff have access to, the pxe booted device will not be listed there, or it is delayed.
I would start by validating your scope includes these systems when they are pxe booted. It is working for the admins because you likely have the "all devices" scope - so no matter what you have access to it.
