Have you looked at the OS Opendata Codepoint? They are centroids, not
polygons. You can see an overlay on OSM on my map here:
I have a simple overlay, that the map uses, too. More details here:
There are Office of National Statistics postcode files too under Open
Gov licence. They have the same active postcode centroids as Codepoint
but with extra detail for each postcode and expired postcodes too.
