Are you supposed to get loads of water / steam out of the flue on a condenser combi system? Installed yesterday and appears to be a lot more steam / water coming out the flue than on the old (non-condenser, non combi) boiler. Any ideas?

Cock on.
If it's just steam (in fact, 'water vapour') once the boiler has got started, all well and entirely normal.
If there's a little bit of liquid water dripping out of the end of the pipe, then the dumb installer has got the slope on the pipe wrong. For condensing boilers, the slope should run back TOWARDS the boiler!
If there's significant amounts of liquid water flying out of the end of the pipe, the condensate connection may be blocked somewhere. Is there water also coming out of the condensate drain while the boiler is on? (Depending on the boiler, in drips, or occasional spurts.) If not, the boiler heat exchanger is possibly nearly full of condensate water! Get the installer back.
