[UK] Name change before getting full license

My provisional license has a minor spelling error in my name. I've booked a theory test and have until Monday to cancel or reschedule it. When it comes to applying for my full license after a practical test, do I have to fill out another form? If that's the case, can I add the correct spelling to my name during that? If not, do I have to apply for another provisional and go through the qualification stage all over again? What I don't want is to get another provisional with my name when I'm close to getting a full license. Or to have to redo a theory test with the new provisional.
