    Income supply cable on the outside of my wall in the porch…

    Hi all, The service cable is on the outside of my wall in the porch. What’s the best way to cover it with complying with current regulations? Would it just be a case of capping it and blocking it out? Many thanks

    Old service head, refer to DNO or not?

    I've got a job in a tucked away property that has an old Lucy Oxford service head. It's been a while since I've come across one. Am I remembering right that the DNO's are generally interested at looking at and changing these? Thanks.
