I agree that the fruity notes in English beers mostly come from the yeast. Though you may get some raisiny figgy notes from darker crystal malts. My favorite English yeast is Wyeast 1318. Nice fruity notes with a bit of nuttiness. I just brewed this bitter and it turned out really well (it's a 2.5 gallon recipe):
