Seems quite reasonable to me. A "hanger" is a device for supending objects. In this case most probably the Vulcan was suspended from a sky hook to give the impression it was flying. Moving the sky hook around the country does cost a significant amount of money.
Now if it was £350k for "Hangar" space, then yes it does seem excessive.
