Re: I had a smart meter fitted last week@ Peter Gathercole
"Roger Witcombe, chairman of the Competition and Markets Authority (a government institution), who was a guest on the discussion about energy companies and overcharging, mentioned smart meters as an aid to choosing supplier,"
One of the few benefits of smart meters will certainly be for prepayment customers. Due to the specifications it is almost impossible to stop prepayment smart meters from having access to all the tariffs available to credit customers, and that should significantly lower the costs for people on prepayment arrangements (currently pre-pay tariffs are generally much higher than credit tariffs). Switching suppliers should also (in theory) be a lot easier, because changing suppliers when you have a prepay arrangements can be quite difficult under current arrangements.
Not that that justifies the near £20bn cost of the scheme, mind you.
