Check the Manage My Booking function on BA.com, this will show you how much it will cost to upgrade with cash, if it is available to you*.
Sometimes their are pro active offers to try and sell the class for around £125, sometimes it is much, much more expensive!
good luck!
*may not be available if the flight was booked via an agent
