Before the present rate of inflation we were already being careful, turning shampoo bottles upside down when they were thought to be emptied, which gives about six more uses of the bottle, only using LED bulbs, washing when the machine is full etc.
So what have we done: turned the heating down ever so slightly, shower for a shorter time, turn the tap off while brushing teeth and on to rinse mouth and basin. Fill the oven when using it.
In short; the same things as everyone else.
We are also being more careful regarding how much cold water we use, as well as warm water, and have managed to reduce our water rates a very little amount.
Cook on the top of the wood burner when it is on, if whatever we are making like soup, or boiling potatoes does well there, and when the top is not occuppied by a pot I have a kettle on, and use the water for washing up.
We ride our bikes whenever possible instead of taking the bus.
We are also eating more home-made soup - it is still the cheapest form of food even when you take the cooking time into consideration.
Rarely use the dryer, and as a rule only have one light on at a time.
