We have a background load of about 100W at night and 200W in the day time, use about 11kWh on average. This is 4 people in a generally gas heated house with a lot of smart devices that are always on. I work from home with a laptop, dock and triple monitors, so I guess that accounts for a lot of the load when the dishwasher, washing machine or oven is not on. I have recently installed solar and batteries and at the moment do not really import or export any power. Come winter I expect to import quite a bit. The big consumers seem to be anything involving heat so the washers, cooking and the occasional use of the immersion heater when there is enough solar. There is no real point sweating about a 5W lightbulb being left on for an extra hour or a device on standby using 0.5W when the immersion heated is using 3000W for 30 minutes.
