Can you please tell me why my Wisteria leaves have gone all curly at the present time? Many thanks.

There are several things that could cause this. The most likely culprits are either too little water, a fungus or a pest. I would recommend increasing water and treating the plant with neem oil, which is both a fungicide and a pesticide (and organic).
There is a chance that it is a disease like curly top virus. This is unlikely, but possible.
