Yeah, we ONLY ship to the UK so under WooCommerce>General Options we have the “sell to specific locations” bit selected and in the Sell to Specific Countries underneath this, just the UK is selected.
Then, under the SHIPPING tab we have a single zone which is UK and then we have various shipping classes showing up there, all with values set. The shipping values all work in the shop itself too, ie they show up as expected when we add items to the cart.
