EV chargers are a much of a muchness, they all have to meet the same regs.Which brand charger do people have at home, wondering which is best. Octopus offer to install one and give a nicer tariff otherwise I've only read about Indra
I would just install which ever had the style you are happy with and features you want for a price you are willing to pay.
The core features really just boil down to:
Does it have a cable permanently attached aka 'tethered' - I'd personally recommend tethered.
Do you need it need to work with solar or tie into other energy eco system devices you may have or are looking to install.
