Thread the other day discussed adding new sockets to old install under new regs....got called to elderly lady who wanted some pendants changing and a new socket added....took one look at consumer unit and my heart sunk, nothing wrong with it just old and no rcd protection, explained to her how much work was going to be involved whilst trying to convince her it’s really not worth it just to put ya Christmas tree under the stairs bless her......did her lights for free and said I’ll pick up an extension lead! ?
