@markah2007 If you have “Dynamic Charging” switched on it tells you in the “Tariff” section on the first screen that “All of your charging will be billed at the off peak rate”.
I’ve carefully checked my Octopus bills, which I have to say are very clear, showing a daily usage graph and hour by hour use with the amount used, tariff rate and price charged. Every day time charge I’ve done has been correctly itemised on the bill.
I’ll try and upload a couple of screen shots for you.

Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
