We had a smart meter fitted a few months back.
Seemed like a sound idea, as it meant that my supplier could take regular readings, instead of relying on their wildly inaccurate estimates (in spite of my supplying a reading every month). That's never happened (although, I did change suppliers about a month later).
Theres a nice little touch-screen box that came with the smart meters (looks like a monochrome sat-nav), which ought to save me going out to read the gas meter, or crawling around to read the electric. Except it doesn't have an option for actually reading the meter.
Total waste of time. It's actually made reading the meters harder as, rather than just look at the counters, I have to poke some unlabelled buttons and hope that the counter shows up.
