I'm laying a concrete shed base for a heavy duty 10 x 8 shed I just wondered is a c20 mix strong enough for the base?

Sorry but are you saying use c30 as this is a heavy duty shed would a c20 mix be fine for a normal shed

No - C20 is strongish concrete for general support purposes. C30 is even stronger and much better when you want to construct what will be an exposed slab.
