Thank you all for your help.
I can now confirm that there is only 1 cable going IN to the box.
Due to your comments I plucked up the courage to open the mcb which was labelled.
My fear of electricity might seem a bit over the top to some of you but my nephew aged 19 managed to electrocute himself many years ago- and it has always stuck with me.
Photos of mcb is attached.
