I don't want to come across as aggressive but ask your registered competent mate :) If he's signing it off for you he will be able to answer the question easily enough.
I'm qualified for installation but not registered so of course I get asked to do gardens all the time!
I'm pretty sure I've been roughly where you are a few years ago. I had just done 2365 and wanted to do my own garden lighting. The conclusion I arrived at was SWA earthed at the glands and buried under cement and in my case tiles was fine. Where it comes out of the ground it is fixed to the walls and it's fixed to the walls for the majority of the run around the garden.
I would ask your course tutor or mate for advice, or just ask the question on the IET site.
I've not read this thread but it might have an answer :-
