Energy Usage

I went away for 3 weeks over Xmas, took meter readings before & after found used 50 units of gas & elec. All appliances off except boiler & freezer. Checked meters and appear accurate so confused how so much energy used. Anyone had similar experience?

50 units of electricity over 3 weeks seems very reasonable to me for general background usage

100 watt average : 0.1 x 24 x 7 x 3 = 50.4 Kwh

Our house averages about 150 watts general background.

As for gas, was it completely off? or does it turn on at very low temperatures. Often insurance policies state a minimum of 10 Celsius to be maintained to prevent risk of burst pipes etc.
