It's a group 1 so should be pruned immediately after flowering finishes. Doing it now is fine but you risk losing flower power next winter as you'll be removing flowering stems and there isn't time for any new ones to mature between now and their winter flowering time.

Thanks Obelixx. I haven't had any flowers yet - my mistake as I cut them back hard, thinking they had wilt, but I'm pretty sure they just lost lower leaves and went brown because of being cold - I'm actually leaving them alone now!
It should flower from November to March when happy so you could give it a good, deep drink (15 to 20 litres poured slowly so it soaks in) and then a mulch of some well-rotted garden compost and/or manure. The worms and other soil organisms will work that down to the roots which will love both the moisture and the nutrients.
Give it an annual mulch and it should flower its socks off - with correct pruning! - altho i find the cirrhosas don't do well in cold, wet winters or exposed to chilly winds so a lot depends on where you have planted it.
