You can do you own test with a known load eg 2kw electric heater should use 2 units of electricity in 1 hour , if your using 30 kw a day its more than a kilo watt per hour , i'm just reading my annual statement for a 3 bed semi its 11 kwh per day,with Gas fired space and water heating .
I did come across a job recently where the property had a dryer cabinet with an electric heater in the bottom and left it on 24/7 for 2 years because the switch wasn't identified it ran up £600 debt !
Make sure you know what all switches are for and if you can't identify them - switch them off one at a time until it becomes obvious what they are for. (check for critical equipment like freezer as you go )
Be careful with on neon indicators - just because the aren't lit doesnt mean the switch isnt in the on position the neon can fail.
If your on communal heating and hot water have you got your own "back up" immersion heater ? switch it off or it will heat the water in the cylinder and will cycle on and off as you draw hot water off thereby cooling any cylinder of stored hot water.
