How much does it cost to boil a kettle?

We are often told to only use as much water as we need in a kettle and not to fill it to the top, but what are the potential annual saving in doing this. Well it takes roughly 4.5 minutes to boil a full (2 litre) kettle with a power rating of 3kW (kilowatts).

First how much does it cost to boil a kettle once?
Kettle Energy to boil a kettle Cost to boil a kettle
Full 0.225 KWh £0.035
Half Full 0.113 KWh £0.017
Next, How much does it cost to boil a full and a half full kettle operated twice a day for a full year.
Kettle Annual Energy Use Annual Cost (and CO2 emissions)
Full 164 KWh £25.318 (60.3kg)
Half Full 82 KWh £12.656 (30.2kg)

Well There it is, a full year of operating a kettle in this way should save you about £12.656 (30.2kg) . Less than you might imagine but if you are a real tea fiend and boil it 4 times a day you would double the saving! Every little counts.
