With the weather deteriating I've still got quite a few
blueberries on the bush, with colours varying from green with a
touch of red through to just turning blue.

It is easier to let them ripen on the bush (although I have to net mine
or the birds will eat them long before they are properly ripe).

Is there a way of ripening these indoors please.

Not really. Taking them off too soon will damage the fruit integrity and
they will likely rot before they ripen indoors. I'm in North Yorkshire
and the last of my blueberry crop ran out last week. None would have
ripened in the last week though it has been raining almost continuously.

Sun is out today so cross fingers you might be in luck too!
