Kreacher to work at Hogwarts. So, without clear instructions to the
contrary, Kreacher was probably free to move between the School and
the Black house.

school.

Carol responds:

My guess is that when Harry and his friends didn't return, Yaxley
appeared in their place as Harry predicted, perhaps with other DEs in
tow. The DEs would probably try to torture Kreacher to get information
out of him, but fortunately for him, house-elves can Apparate without
a wand. Kreacher probably escaped to the only safe place he knew of,
Hogwarts, where he had previously been assigned to work (but did as
little as possible). It would not be safe to return to 12 GP since the
DEs might take it over, and there would be no point in staying there
without Master Harry, so he would begin working at Hogwarts as Harry
had wanted in the first place. (For all we know, he became friends
with Dobby, who must have been astonished to see him wearing a clean
tea towel. :-) )

Carol:

Well, that's certainly true, or the narrator would have told us
otherwise! Seriously, though, who would have thought that a little
house-elf could rescue six wizards and a goblin from Bellatrix, the
Malfoys, and Fenrir Greyback (Wormtail having conveniently been
strangled by his cursed hand)? It would simply have brought Kreacher
into terrible danger (and the Black sisters would have regarded him as
a traitor, just as they did Dobby). I'm not surprised that it didn't
occur to Harry. I wouldn't have thought of it, either, in his place.

Carol, wondering why goblins can't Apparate without a wand if
house-elves can
