Are late address changes considered by Grammar schools

[payel123]

Hi,I live in Stoke-on-trent area currently but would be moving to the Trafford area around August end.We wish to move in the Altrincham area(depending on availability of houses to rent).Just needed one information.As I would be applying earlier for DS eleven plus with my current address,will an address change just before the entrance be acceptable to the schools?Thanks in advance...
