Perhaps if NATS spent half as much time and money and effort as it has on convincing us the pension is beyond redemption on petitioning the regulator and or government to allow it to charge for all of it's costs rather than just some, the situation may be different.
Which other companies, or indeed businesses, charge for a service knowing that charge will not cover it's costs. Why has nobody challenged this ridiculous 'cost passthrough' thing. Apparently NATS is supposed to be a profit making business.(Don't say it will require a change of legislation so can't be done, as I seem to think PPP'ing NATS required a certain amount of civil service work too!)
Also, if this new 'deal' comes to pass, how about a review in 5 or so years when hopefully the economic markets will be on the up again. If the surplus is back or growing, perhaps revert back to the current status quo.
