Hi Christina
The timing is not particularly unusual, though the time can vary in different parts of the country.
Sometimes people are offered a home visit without requesting one on the evidence which has been submitted - deeming it more appropriate than asking someone to come to an assessment center. (It is also possible that a home visit was the only available appointment).
You can request an appointment at an assessment center if you don't wish them to visit you in your own home.
