Hi all
Thanks for all the replies. I have not played around with it as yet, if it is live would I be able to find this out with one of those mains tester screwdrivers and if that is negative would I be OK in thinking that I could cut this then.
Or would it still be wise to start removing the plasterboard to see where it goes, ideally I would like to avoid this if possible but if none of the above are an option then I'll bite the bullet and get in a professional.
Thanks again.
No a tester screwdriver is not going to help you here, and regardless are not a safe method of proving safe. I wouldn't bother ripping out extra plasterboard as that will just cost you extra in the long run which you might as well put towards having someone come and do the complete job for you.
