I was looking at some energy prices today and the average selling prices were listed. Domestic gas around 34p per kWh, bottled propane price was around 10 times that!
Calor Propane is currently almost 10 times the price per kWh of domestic gas, and around double the price per kWh of domestic electricity.However with the huge increase in the price of electric many sites will probably install metering which will come at a cost. Using gas for hot water and the fridge may be a better option. Unfortunately using ags for heating may not be an option as you wil use approximately 6kgs on gas in 3 -4 days if you are not careful. BTW our fridge seems to work better on gas than electric and cools down quicker.
