yes, the uk belt is fine.
The Halfords 825e belt is quite tight, you'll probably have to pry it on with a screwdriver, with the alternator screwed in as close as possible. The next belt up is the 845e, which is a bit on the loose side, even with the alternator screwed all the way out
Also, the Halfords belt is only a 4 rib belt, whereas the Nissan belt is 6 rib, and probably a better fit..... I've got the Halfords 825 on mine, but wish I'd forked out and got the Nissan one, as I think I may be knackering my alternator bearing...
