The BB (shimano UN300) on my commuter / tourer has worn out after 6 months, is this normal? It gets ridden about 25-40 miles a week, with an occasional longer trip, so not much more than 1000 miles in total. I do have to keep it outside and it's pretty exposed to the elements when locked up at work.

Unfortunately that doesn't seem to be an uncommon life for bbs of this kind stored in those circumstances.

I've made mine last longer by keeping the bike covered with a groundsheet when outside, held in place with market trader clips.

Shouldn't be, bring it back to the shop or notify the retailer.
