If you can, take a look at the Mitchell 308X in the 5 bearing and 10 bearing designs. I have a pair of the 5 bearing ones and it is an absolutely wonderful light reel. Not sure of UK prices but $40 or $50 US for the reels depending on the number of bb you get.
I accidently would up with a mid-teen carp on one and it performed fine. I don't backwind so it was me, the fish, the clutch, and a very limber rod.
