Hi guys, as the title suggest. Friend of mine buying a brand new house from a reputable and well established builder. however it has already been 1st fixed. He\asked the builder if he could have an U/G supply taken out to the detached shed. Yes they could, no problem. Method. To tap off the kitchen ring final circuit. I would of thought a separate circuit from the house consumer unit would be required. Is it still acceptable to tap of the ring final circuit? I know it used to be done that way years ago. Thoughts please.
