EV smart charging is a solved problem in the UK IMO, at least for those with a parking space.

OVO[1] and Octopus[2] offer smart charging tariffs that give EV owners reduced electricity rates.

The usual caveat is you can only benefit if you can install a charger and park near that charger. Still, based on this 2021 article [3] 65% of UK homes have at least one off street space, so the potential for a majority of homes to smart charge is there.

To extend the benefit of cheap smart charging to more people, it would be good to see legislation that makes it easier for leaseholders and renters to require the installation of a smart charger where technically possible.
