Thank you barry island - I would say our boxes are too high off the ground judging from your advice - most are at approx 4 metres. What a pity it is too late to move them this year.
Maybe just carefully open to check they're not being used first.

I'm keeping my fingers crossed. Last year the bluetit's mate abandoned her so she only laid 4 eggs which came to nothing.
