Government trust fund for chilren

Those of you who have recently had or are soon to have children born in the UK should check this out:

and make sure your child gets it!

I wonder if this program applies only to families who already reside there, or if it can apply to children whose parents permanently move there in future, and whose birthdays qualify them?
