Turns out he had to install a traditional meter because it was out of hours for OVO to give codes for a new smart one.
This means that we have to yet another visit to have a new smart meter installed
Why can't a battery simply be replaced under such circumstances. Should be quick and easy. It it isn't easy, why on earth not?
Why can't the unit send a warning beep to us and send a message back to base when low battery is detected?

I'm afraid they're not separable @GasAndGaiters.
Unfortunately it isn't like replacing the batteries in a remote control. With this, if the battery has failed then the meter will need to be replaced.
I'm sorry that a smart meter wasn't initially fitted and that this has resulted in lots of to-ing and fro-ing for you. I hope that this has now been resolved.
