Cook in bulk.
It saves both money and time. By making several portions of the same dish at once and possibly freezing them for later, you avoid letting food get to waste. Another benefit is that when you have a lazy evening and you don't feel like cooking instead of ordering food in and spending money, you can pick one of your pre-made dishes from the freezer.
Go to the supermarket several times a week.
Another way to not let food get to waste and thus save money is by frequenting the supermarkets instead of going once per week. It will force you to buy smaller quantities but more precisely for what you need the coming days.
Choose your meals first.
A third and important way of saving money on food is to know upfront what to buy. Do not go into a supermarket buying random products that you assume will be useful ingredients for your meals. Think first of what you want to eat in the coming days, then write down the ingredients on your shopping list and stick to that list while shopping.
Devices in standby.
Always unplug chargers and avoid letting electrical devices such as TV's be in standby mode. Sure one individual charger left plugged isn't something to worry about, but you'd be unpleasantly surprised to notice how much all of them combined actually use. One way to solve this is to use extension cords with switches for each outlet and switch them off and on manually, or for Google home or Alexa users smart sockets are an option that allow you to turn on and off your devices using voice commands.
This should be a no-brainer for all households. Install LED light bulbs in all your light sockets. LED light bulbs consume at least 75% less electricity and have more than double the lifespan as a regular lightbulb. They are more expensive than regular lights but definitely affordable and the return of investment is already achieved in a matter of months.
Ask your electricity provider if they offer off-peak electricity. By having this system you can opt to only turn on your high electricity consuming devices, such as washing machines and dishwashers, during off-peak hours. Depending on where you live and the electricity installation you currently have this might require some additional investment.
Invest in solar.
For those willing to invest more, should definitely look into investing in solar panels for their house. The current return of investment is about 6 to 7 years. On top of that you are helping the environment!
Collect rainwater which can later be used to wash the car or water the plants. This is a very small investment to make that has immediate returns.
For those willing to invest more, let the water get collected into a rainwell and connect it to the house water system. This will allow you to flush the toilets and wash your clothes using rainwater. You could potentially save up to 40% on your water bill.
Last but not least another important way to reduce expenses around the house is to be aware of what your expenses actually are. We suggest to keep track of your income and expenses in order to get a clear view of where your money goes so that you can budget your finances more easily. One great application that allows for such budgetting is called Toshl. It is very easy to use with great overall functionality and on top it looks great! It comes with both a free and premium version.
