Using 33000 avios plus 80 quid gets Business return. Certainly not the same value as a RFS in Europe, but seems like a reasonable use of avios. or could for 27500 + 140 quid.
Cash fare is 460.
I know it's hard to value these things, but does the cost per avios seem like a reasonable redemption here. I'm not UK based, so can not take advantage of 241s and other promos.
