My contract with Scottish Power is coming to an end and I'm looking at switching to OVO or to First Utility (who are a bit cheaper). I have smart meters (Secure Liberty 100) installed by First Utility when I was with them previously. They are currently functioning as dumb meters.
Astonishingly, First Utility have advised me that if I switch to them, there is no way they can make my meters smart again (except replacing them).
Will the meters become smart again if I switch to OVO?
Thank you
