I have recently bought an electric van and would like to be switched over to economy 7 so I can charge it at night at the lower rate. I understand it will cost approx. £100 to get the meter switched over. But I also want a smart meter eventually, Would the eco 7 meter be replaced by the smart meter when that gets installed and pointless to put the eco 7 meter in now if next year it will be replaced? I also have solar panels installed and I heard there was a problem with micro-generation and smart meters, has this been solved now?
