SMETS1 Upgrade for EV

I would like to switch to the EV Tariff, but have been told we have a SMETS1 meter. From a quick bit of research it sounds like the meter can be upgraded rather than be replaced.

Can someone from Bulb let me know if our meter is currently connected to the network (I think it is sending readings), and if not can it be upgraded without replacing the meter?

Thank you.
