The most comprehensive listings that I have come across are at:
http://www.frequencyuk.co.uk/
But I can't personally vouch for the accuracy or the up-to-dateness, but I would be surprised if it was not very good.
A useful digest for civil airbands that is very usable can be found at:
http://www.lowe-electronics.com/frequencylist.htm
Again, the same caveats apply.
I came across these while researching what airband scanner to buy. As a matter of interest I chose the Yupiteru MVT7100 - from ASK electronics, who had the cheapest price.
