I did this for my wedding. Just know that it is what you need, a signed statement. When we went to London to get it, the girl at the window tried to tell us we were wrong, luckily I am a tad stubborn and got it anyway. One more note, everything that is paper for the wedding will need to be apostilled and they will keep it all. My husband's birth certificate, the original, is forever on file there. Congratulations and best of luck!
