Blue tits - box roosting

[Tinkerbell]

Has anyone any idea when blue tits generally begin using empty boxes for roosting. We've seen plenty of curious activity in the garden recently as the tits inspect the boxes, but it seems to be rather early for this behaviour. Hope it's not a sign of an early Autumn and Winter!

Tit species will use nestboxes for roosting all year round - just more often in the winter, so I shouldn't think it's that unusual for birds to be using them now.

Last year, it was on Boxing day for my camera boxes.
I guess the cold is one of the biggest factors.
