Paul,
It's tomorrow, but no point in telling you, you already know, are you ready? I put this in Jamie's post & it applies equally to you.
I know it's a waste of time telling you, but don't worry about it, go & enjoy the experience. Just take a full tool kit, battery drill if you have one, tape, tiewraps, edge trim, foam, anything you think useful. If the inspector is anything like the lads at Nottingham they actually want the car to pass, but they have a job to do. It's not personal to you, it's a box ticking exercise, remember also as far as they know you could be a plant from VOSA checking up on them, so they have to prove they are doing their job correctly as well.
Good Luck, pretty sure you won't need it, it's another superb build & the inspector will be impressed
Alan...
