Sorry, no.
You keep the flexibility of the fare you have paid for. If your fare allows a £50 change, you have to pay the £50. If it is a non-changeable I class booking, it will stay non-changeable. The main difference is that unlike MFU bookings where you lose the upgrade whenever you amend it part-travelled, you can keep the upgraded cabin on a GUFT booking (assuming the underlying fare permits a change) for the relevant change fee.
