I was thinking IO but that peak unit price is horrendous when they work put our unit price each month on agile it’s usually around 15p even with eV charging Octopus compare makes Agile at least £300 a year cheaper. I guess if the house is empty all day you’d do much better off on it than that. Maybe once solar starts outputting more it’ll shift the math but it’s those blue periods that really dent the bill.
I turn the target temp up on the ASHP and put everything on lol
