All Aberdeen departures on airways or advisory routes should have a clearance on the ground "climb to maintain XX climb when instructed to FPL level".
Southbound departures via Findo (ahhh) will then be climbed to FL250 as the standing agreement between Tay and the next sector. Pretty bog standard procedure you will find on any airways flight in the UK.
Don't know what the "FLxxx en-route" is meant to mean.
