You need to make a Specific Issue application under section 8 of the children Act l989 (quoting you chapter and verse so you can look it up on google), unless you can get her father's written consent.
If he objects then the procedure is fairly lengthy - you should allow 6 months from start to finish, possibly longer, so you need to factor that into his plans.
The Court will have to take into account your daughter's wishes and feelings, as set out in a Cafcass officer's report (that's the thing that takes the most time as Cafcass are woefully understaffed), but also other factors such as educational, social, emotional etc.
You need to put forward a strong argument as to why she will benefit from being uprooted and taken so far away, and then uprooted again in two years' time. You also need to have properly researched proposals for how contact will be effected if you're successful, eg how many times you'll bring/send her home to see her dad per year, how much that will cost and whethr you will pay all of that cost, how you will organise indirect contact in the meantime, eg emails, cards, webcam, phone calls etc.
