I can't speak for the iPace issues (we didn't go for one as the rear space was a tad small for a rear facing child seat). But I can relay direct experience of using Octopus for cheap EV charging as we took delivery of a BMW iX last week via octopus (my employer's salary sacrifice provider).
We had a 7kw charger installed by octopus as part of the lease deal and they were very good. The installation was a week later then they said it would be, but was still done well ahead of the car coming. To compensate they gave me a £30 prepaid card to use for public charging. Nice gesture I thought.
The installation team were great and hooked up the smart charger in a morning (only about 15mins with the electric off). The octopus charging is all controlled through the app, I simply set my desired charge level and departure time and octopus schedule the charge slots. This means you can get more than the 6-7hrs of low cost electricity. For example tonight I'd run the battery right down and need to leave by 0730 tomorrow, so it's charging from 2200 all the way through to 0730. All at cheap rate.
So far, it's all worked faultlessly and if it continues, will be much more convenient than an ICE car for us.
As for the iPace, I did a test drive of almost all the premium SUV/crossover EVs and it was the nicest to drive by a good margin. Not as refined as the iX on the motorway but a better drive in every other respect.
FWIW I think they're a bargain second hand.
