Norway is a much drier climate than the UK so the cold feels completely different and despite being a lot colder, is much more manageable. I've climbed in Norway and been out on the artic plateau in winter down to nearly -30C with most days being about -15 to -20 and I've been colder and worn more layers on the north face of the Ben in winter over here!
I didn't have anything particularly special gear wise and certainly nothing that I haven't used in the UK. Most days, if I was moving I was just in a merino baselayer, R1 fleece with my Atom LT over over the top and maybe a wind shell if needed. I used normal softshell trousers and had Powerstretch leggings on underneath. I wore my insulated B3 boots and Smartwool Mountaineering socks and had a down jacket for when I'd stopped. I just used my usual winter gloves most of the time but carried a pair of Dachstein mitts as well which were nice to have sometimes.
If you're heading out onto a glacier, a decent pair of sunglasses is a must and don't forget SPF lip and face protection!
