How much power in KVA does an average 4 bed detached house use per annum?

First let's get the units of measurement correct. Power and energy are two different things. kVA (or more commonly kW) is a measure of power. Use per annum would be a measure of energy, kilowatt-hours (kWh).
Energy is calculated multiplying power (kW) times the number of hours (h) to get kWh.
It varies widely but the average 4-bedroom home uses roughly 15,000 kWh annually in the U.S. That equates to an average power demand of 1.7 kW over 8,760 hours. Microwave ovens require 1.0 - 1.5 kW of power all by themselves, coffee makers 1.2 kW, electric range 10 kW, clothes dryer 2.5 kW. How long these devices are in use each year determines the amount of energy... kilowatt-hours (kWh).

You think somebody is using your electric supply?
You would not be the first person to have someone else tap into your electric power. If you are in a detached house, it is fairly easy to find out. Turn off everything in the house. Leave the circuit breakers on. Have someone stand outside by the meter. See if the meter still runs. (You may need to turn off the breaker to the hot water.) If the meter is still running when nothing in the house is turned on, you can call the power company to come out and check.
