This whole approach by HAL is a wilfull misinterpretation of their
right to levy a charge so as to recover the past cost (including
financing) of the tunnel link to Heathrow. That is all they are
entitled to.

Almost all the fee *is* recovering the past cost. They are actually
proposing reducing the operating expenditure portion from 19% to 16% of
the total.
