Thanks for the clue, this was a good pointer.  I've figured it out...

It was this.  I needed to add '--efi-directory /boot/efi' to the command.

Turns out there is a short grub.cfg in /boot/efi/EFI/ubuntu that 
contains a 'search.fs-uuid' line that needs to point to the new 
partitions.  Running

     update-grub --efi-directory /boot/efi /dev/sdX

and replicating that across the three partitions has now worked
