@Collie I’m on Octopus Intelligent Go, same car, mileage and situation of being in the house during the day. From what I can work out OIG seems to be the safest bet. Agile may save a bit but with OIG I can charge the car and run stuff like the washer, dryer and dishwasher any night at 7p/kwh.
With the new Ohme app and Dynamic Charging you can also get slots during the day at 7p, I had to do a day time charge earlier in the week as I had an unexpected long trip to do, put it on about 10am and was fully charged by 6pm.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
