Hello , I haven’t ever heard of meters being described as ‘alien’. I have heard of complex, but not ‘alien’. Does your daughter use electricity for an immersion heater or storage heaters or does she have gas central heating and water heated by a combi boiler? I have a complex meter (see my posting on the E.on existing customers thread). How many MPAN’s does she have? I need to have my meter changed and E.on can offer me either Economy 7 or Economy 10.
