Are you charging from a granny lead, or a 7kW charger. If you're on a granny lead, it will only pull 2.4kW I think. On a proper (7kW) home charger, the car will pull 3.6kW.
Check with Octopus if you can get the 5 hour version of Go (slightly more expensive at 5.5p).
I'm not sure what the charging losses are like with the Leaf, perhaps someone who has one can confirm, but you could maybe get 10-12kWh in every night on the cheap rates if you're using a granny lead, or 15-18kWh if you're able to draw 3.6kW.
My only power hungry device is the oven. I found it was really difficult to avoid cooking during the peak, but YMMV,
