Mick this may interest you i was told by the Octopus Energy technician who fitted my smart meters that a further hour is being added to Intelligent Octopus Go this will give 7 hours, overnight at 7p per kwh. This would give you 49kw at 7p.
Ooh, hope so! That would be nice for those odd occasions where you’re low but definitely want to be starting with a full battery in the morning.
