OFGEM reckon the TDV for electricity is 2900 kWh per annum, in a dual fuel household. That's the average North to South, city to countryside, flat to mansion. Or about 8 kWh per day.
Mine is now down to 5 kWh per day after ditching my guzzling freezer. We have an extended 3 bed semi in suburbia. Just me and SWMBO in the home 24/7. We're retired so are about most of the time. We heat with gas , and cook with gas. We have a solar thermal panel which really lowers our water heating consumption in the summer. We have all the modern conveniences, washing machine, dishwasher fridge freezer tumble dryer, Two TVs, two cable boxes and a router. one main Computer and one laptop. LED lighting throughout. Mobile phones on charge.
While there are issues about floor space, wall sizes, loft sizes and insulation when it comes to heating costs - those factors don't have much relevance when it comes to electricity (non heating) consumption. What drives electricity consumption is the appliances we use and how often we use them and their energy efficiency.
The other thing is observation, devices using electricity give off heat. So if things are warm when you wouldn't expect it that's something for investigation.
As I said before I don't have a smart meter, never wanted one and am not at all impressed by the claimed benefits. But I can and do read my actual meters often,
I also use a meter like this

to establish what appliances are costing me a lot. Obviously a big appliance (usually in the kitchen) will use a fair bit, but the monitor can be left in for a week or more to establish its fair consumption over time. Then you can decide whether you have to keep it plugged in and working, or whether it might be beneficial to replace it, or just turn it off when not in active use.
