I used to operate a Signature based aircraft from Luton and due to the insane location of their new hangar (which would have been perfect for Gulfstream to move to - leaving the operational hangar on the signature ramp), it looked like there would be significant increases in de-icing charges during winter ops.
Aircraft cannot depart from the new hangar location (next to DHL / Harrods) so they have to be towed to the signature ramp. But if LVP is in force, aircraft would have to be towed the night before - and then stuck with having to de-ice where before you could remain in the hangar until you needed to refuel just before departure.
Just one big reason I'm glad I left that operation.
