QuoteHowever, they would have to charge their automobiles between 4 a.m. and 11 a.m., which might be a small sacrifice.

You've misunderstood the announcement.

The 4-11am restriction is for "ready time" meaning you plug in the day before and the time you want the car to be "ready by" has to be in this window. Octopus will schedule charging at any point overnight to have your car charged to the desired level before your set time, even if it takes all night.

It's neat but I probably spent about £150 on charging all last year on octopus agile, IIRC it worked out to about 6p/kWh.

Do your maths. Only costs in if you average >1200 miles per month off of your home charger vs the ~2.5p/mile a 7.5p/unit off peak tariff gets you.

It doesn't say anything about public charging being included in this monthly fee.

Basically if you live >30 miles from your 5day a week place of work AND don't need public charging to get home again, it works. (Ignoring weekend driving)

Also these Smart tariffs usually have your charging switch on and off during that off peak period increasing the number of cycles of the relays / contactors by probably 4 to 6 times.
