IIRC didn't you say E.ON couldn't do E7 Smart Meters?
Had an email from E.on this morning (almost) telling me that I had to have a Smart Meter. Rang 'em up(*) to reject their kind offer but their systems where down. I still asked if E7 ruled out a SM but they said no, they can do an E7 SM.
(*) WTF does the automated system want my DOB?
