3-pin charger for electric vehicle (Nr Bromyard HR7 4SH)

My new car sadly back in garage for a month, I have use of a loaned electric car meanwhile but although it can be charged with 3-pin 'granny cable' it only has the big charger cable (for which I don't have a charging point installed) My travel needs are simple but essential as no public transport where I live, so just need to charge vehicle overnight using 3 pin charger. I'm wondering if anyone has such a cable they don't need/use please, really only need to borrow until my own car returned. Know this is a bit of a long shot but worth a try, hoping someone out there can help.
