Pancakes as a breakfast food are just not a British "thing". We tend to prefer toast, or if you're having a cooked breakfast, fried bread.
As for pancakes, well they're treated as a sort of afternoon thing to have with tea. If we're going for the drop-scone approach (Which is close to the American version) then we'll have them with a little jam, or lightly buttered.
If we're looking at something thinner, like crepes then any number of things can be put in those. :)
