Your average usage of electricity tends to increase remarkably if the size of property you live in is bigger. i.e., 3 to 4 bedrooms.

Those who work from home on regular basis will also notice an increase in their electricity consumption.

A good use of day light and turning off the appliances when not required can make a huge difference in your average electricity usage.

Average gas usage

Again, it depends on the number of persons living in the property but an average usage of gas in a two bed-room flat is round 9,000 to 10,000 kWh where majority of this usage comes from heating.

Heating a two-bedroom flat is not a big deal and required a way less than energy than a bigger house would do.
