I have installed a plug in the cupboard to the left of the stove and cut a hole in the panel so that the plug can be plugged in on the left side. This is great for new installations, where you can plan it from the beginning. The rest of the time, there is an isolator at the top and a plug below the counter for the hob and oven, preferably Crabtree 16 Amp double.
Here by us most houses have a 25Amp point of supply from the council and if you are lucky a 30Amp or 40Amp supply. Most houses have gas stoves or gas hobs with built-in ovens, both need a plug to work from. We even have a couple of gas heaters that work from a 16Amp plug! What is wrong with 2 Eveready batteries?
