I think that when it rains hard in a certain direction the flue on my
condenser boiler lets in rain water. This then runs through the boiler
and drips out from the bottom front corner. Does this sound possible?
It is definitely rain water as it never happens when it is not raining.

If this is happening you have a serious problem which should be
investigated immediately. The flue is connected (obviously) to the
combustion chamber and that combination should be totally sealed to the
room. It could be water is leaking round the outside of the flue and
finding its way into the room from there. But that too should be sealed.
Or, of course, the condensate drain if it's a condensing boiler.
