mu plumber has installed a shower waste pipe for me. But it doesn't look like it is low enough on juices to have a fall. Is raising the shower tray a good way to ensure the fall?

Not sure what waste pipe "juices" are but so long as its not falling the wrong way you are unlikely to have much problem with it even if it were level unless your lodger is Chewbacca. Obviously its not ideal and the higher the shower tray is the more pressure will be on the drain so any crap will flow through that bit better so raise it if you are worried.
Yes, raising the tray will help with the fall. Is this the same muppet who wanted to fit a 37kW boiler in your house? If so I'm surprised you're persisting with him, he doesn't seem to know what he's doing

You don't need a steep fall anywhere. If you have a small fall from the shower tray and then a steep or small fall you are golden. You'd even be alright if the pipework was horizontal (no fall) for a small distance.
