We applied but never got the BP charger, so I had our own Viridian dumb unit (brilliant quality) charger fitted. I just use Octopus Go with my Ioniq 5, use the car’s own charge schedule software to charge between 12.30 – 5.30am. The price difference has come down, Go is now 8.1p, vs Intelligent Go at 7p, so there isn’t much in it except for the extra slots provided by Intelligent Go – although recent changes there have seen them reduced as Octopus refines its software and understanding of the process.
Tried to get a new unit with Motability when we ordered the Ioniq 5, All seemed well, until Ohme did a survey of our place and said no chance – despite it just being a direct swap of the existing unit (same RCB, same 6mm cable).
EON Next Drive looks good, a saving with its 6.7p off-peak car charge rate, but its peak fees are over a penny more than Octopus, Standing charges are 6p more, so no savings to be had for us there.
In life, it's not who you know that's important, it's how your wife found out.
