Probably best to start a new thread because I'm guessing you mean a paid-for upgrade rather than using miles.
But in general they will charge the difference in ticket price - ie it will be expensive. If they are OP-UPing, they might do a deal. But usually it's Elite that is hardest-to-get on LHR-BKK.
