Sorry, quick edit:
I managed to get it priced up, but it comes to a different WT+ price, which seems strange. About £150 more expensive when doing the UUA.
It says non-refundable. I'll just assume it's that on the UUA too.
Thanks for the help.
Again, another edit! Just realised the higher price on UUA is perhaps because it's a higher class WT fare, in order for it to be able to upgrade to business class? If so, maybe it is refundable. Argh!
