You DNO should assess the supply capacity upon receiving the completed form within a maximum of 10 days.
DNO is National Grid. They accepted the number you gave me and now want to check the fuse is up to the new requirement. I must admit I really want to go on a decent drive at night, somewhere dark so I can appreciate the lighting.
Be careful when driving at night, the Ioniq5 despite having fancy pixel headlights, they have been shown to be very poor on dark roads.
