Can anyone help, my uncle has just asked me if i can add another meter to an existing meter, basically he owns a property with one single phase supply, then he converted his rather unusually big garage into a second home!!! now he is renting his property and is now living in his converted garage. What im asking is can i add a meter to his new converted garage from the existing supply in the house without asking Weston power to do so and would the meter i fit say a landis and gyr E110 be valid to the electricity company ???? I have no idea as ive never been asked to do it, obviously im fully qualified with NICEIC.
