Here are the things that we do to cut our food and energy costs:
Only using appliances to cook dinner (cereal for breakfast, sandwiches and fruit for lunch)
Making DH a packed lunch each day (otherwise he will easily spend £8 a day buying lunch!!!)
Using a slower cooker 4-5 times a week (costs about 1/3 of the price of using the oven)
Boiling the kettle once in the morning and filling up a big flask with boiling water to use throughout the day for tea/coffee rather than repeatedly boiling the kettle all day.
Washing on cold setting and hanging all washing outdoors to dry.
I have stopped using the dishwasher, we still pop all the dirty dishes in the dishwasher so they are out the way during the day, I then hand wash them and pop them back in the dishwasher to drain at the end of the day.
I got a ‘baby dam’ to put in our bath so that when the little one has his bath we are only using half as much water as if we filled the whole bath.
We put the thermostat to 18 in the morning, then once the house is up to temp, we turn the heating off for the rest of the day (the children and I are all home all day). We don’t put the heating on again until 7pm, again only to 18, then off for the night once the house is up to temp.
No lights on before 6pm (We are lucky to live in a house which gets lots of natural light during the day, we could not have done this in our last house which was very dark due to it’s position).
We have changed all our lights to energy efficient LED’s, have all appliance on smart plugs so that nothing is in ‘standby’ when not in use, and have insulated the hot water tank with a thick ‘jacket’ and added thick lagging to all the hot water pipes which has made an enormous difference to our bills.
Added an insulated backing to our curtains.
We eat meat 2-3 days a week, eat vegetarian the rest of the week to keep food costs down.
We have added a ‘bladder’ to the chimney to insulate it from drafts.
Additional to this, I am trying to be wary of our car use due to the increase in fuel costs. We need to shop twice a week due to not being able to fit a whole week of food in our little fridge to feed our family for the week - I am trying to make sure I combine the grocery shopping with other trips such as taking the kids to the farm/swimming, or doing a dump run etc instead of doing multiple trips for a single purpose. We have also stared walking to things like the kids clubs and music lessons (a 20 min walk each way) instead of taking the car.
