Curious pax, I'm not so sure. If you take BAA, look at what they're doing with LHR, massive new T5, then T6, 3rd runway, and the demolition of around half of the central area to build 'Heathrow East'. LGW, no massive developments since the arial walkway/bridge but always in a nice condition and state of repair, same goes for the other airports in the group. Seems that they (BAA) are investing more in their airports.
Another thing that comes to mind is that if council tax bill are subsidised, then how high would they be, hardly cheap now
