Smart Meter Installation Arrangements

I would like to have a smart meter installed with a view to changing to EV Tariff when (if) I finally get my electric car later this year.
However, the Bulb website currently seems unable to process my request.
Could somebody please clarify how I can arrange this?

I wouldn’t be too quick to have one installed. Many including myself have faults with them which bulb seem incapable of fixing/replacing. They are happy to steal money through over inflated estimates in the meantime though
