Except you can earn money that you post to the grid… of course it’s a different rate vs what you consume, and you need a smart meter… eg https://octopus.energy/blog/outgoing/ is currently 7.5p per kWh
My understanding is that it only applies to existing installations and that new installations aren't eligible for the feed in tariff
That is not Feed In Tariff… FIT was a government scheme to subsidise early solar adopters. The new scheme is just market economics - you generate, someone buys. In theory eg https://octopus.energy/outgoing/
My SIL sent me this last night, he works in the management team of the future product development area for them, they took it up the FOS hill yesterday as well. Some incredible figures here..

I saw the Pro at Goodwood Friday doing the hillclimb. - it was F***Me what the H*** was that? Quick. That along with the new record holder reminded me of an insane grown up scalextric set with noise being extremely similar to driving the model cars flat out.
I'm sure this has been discussed on this thread but I found it fascinating when speaking with an electrical engineer, who specialises in EV wall boxes, that the government/power companies can limit (control) the amount of power going to the wall boxes. He explained how it was done but part of it was lost due to the technicality of his explanation and the other part due to us being in a noisy environment; however, the gist I got was it was in place to help the government 'manage' power should their be shortages / times of crisis. The upshot seemed to be that they could turn power off to EV wall boxes, should they deem it necessary.
As I said, probably already discussed on here but not something I was aware of prior to the chat but made sense, if feeling a little too intrusive.
My submeter that feeds the chargepoint did have a sim that sent usage info for gov research (now disabled) but the way mine is cabled they would have to restrict my whole house
A little known fact is most of us don't get full 240 volts nowadays, another way of stretching the supply
I've not heard that this has actually been needed to be implemented yet, but it makes a lot of sense to have mechanisms to remotely implement load balancing if people won't voluntarily do it themselves.
The National Grid has for many years (at least since 2008 or so, when I first saw it) had a well-defined process for managing situations of reduced electricity supply through rolling blackouts, initially for just half an hour at a time but with the capability to extend for longer if needed, but as far as I'm aware it's never had to be implemented. The Grid is constantly running on a fine balance between supply and demand, that's how the whole system is designed to operate, and EV chargers are just one more way to help balance that load - not only in terms of load (the chargers) but also in terms of supply (V2G). The latter is going to offer potentially some useful extra income for EV owners when wholesale electricity spikes come.
The thing to remember with all this kind of resilience and capacity planning is that it makes excellent engineering sense to design the capability into the systems right from the start, even if it's never going to be needed.
