Chicky, yes. When each flowered stem has finished cut it back right to the ground. However. Look out for smaller flower spikes emerging on those flowered stems and cut back to them. Then cut back to ground when they have finished. I take off all heavy stems leaving just soft growth. I also often divide them and pot them up.
A tidy up ...removing rotting debris and possible lurking snails (lupins seem to get attacked by a lot of tiny snails at this point) ........and a feed of fish blood and bone will prepare them for an even better show next year.
Yes, maybe a bit like haircut for your geraniums, which I do every year in mid summer
