how can i lower my gas bill?

Heating water for tea and washing up on a gas stove is very inefficient. Buy an electric jug which will heat water much faster and more efficiently (i.e. cheaply).

I must be a hippie as I love cooking on gas lol

Heating water for tea on gas stove is expensive though. Kettles do it faster & cheaper now. You might think about buying one. You can always turn it off at the power point between cuppas (I turn everything electrical off when not in use)

Turn down the gas when you have almost finished stir fries... the wok should be hot enough.

With washing up I'm not sure. Unless you use a lot of water, then try cutting down.

Is it the actual consumption or the charges? My gas bill is higher, thanks to the Carbon Tax, for less usage this quarter.

I am using a water bolier and a vacuum flask, my tea stays hot enough for 12 hrs

I am of course a hippie and drink yoga tea :)

Hippie. Only old, sad, alone hippies use gas stoves.

You might heat that water in your microwave.
