Could you save money by using your appliances differently?

Bad kitchen habits could be costing you

Save money by only running your dishwasher when it’s full, but not overloaded

Kitchen appliances can add a hefty amount to your electricity bill – especially if you’re not using them in the most efficient way.

Bad energy habits mean homeowners are potentially wasting money, according to a survey of 1,000 people by Appliances Direct.

Overfilling the kettle, not stocking the fridge and freezer to the optimum capacity and buying bigger kitchen appliances than are really needed were the most common pitfalls.

If you suspect that your kitchen habits are costing you dearly, take a look at our tips on reducing the cost of your electricity bill and our guides to buying energy-efficient appliances.

How to cut energy costs


Nearly 50% of people boil more water than they need when using the kettle on a regular basis, according to the survey. 

If you only make one coffee or tea at a time, make sure you look for a kettle with a low minimum fill line – some make you boil more than you need, which means you’ll waste energy and money.

When we test kettles we check how much energy it will really use – visit our kettle reviews to find the quickest, quietest and most energy efficient.


To not waste energy it’s best to run your dishwasher only when it’s full, but not overloaded – something that one in five people surveyed don’t do. 

Using eco or energy-save programs can also save around 20% on energy a year compared to using the main program.

But it’s also important to buy an energy-efficient dishwasher – the worst we’ve found costs more than £70 a year to run and the best around £30. Look for the energy-saver logo in our dishwasher reviews.

Fridge freezers

To keep running costs down, make sure your fridge and freezer at least three-quarters full where possible to make sure you’re cooling food rather than air.

If you’re looking to buy a new fridge freezer then make sure you get one you’ll be able to fill. Manufacturers state the capacity for each model, but this is measured with all the drawers, shelves and racks taken out. 

For our tests we leave these in so you know how much space there actually is to use. Visit our fridge freezer reviews to find the right one for you.

Energy efficient appliances

Three-quarters of those asked didn’t factor in energy efficiency when shopping for kitchen appliances.

It’s important to know exactly how much it’s going to cost you to power your new appliances, especially when we’ve found big difference between good and bad models.

For example, the most energy-efficient fridge freezer in our tests costs just £25 per year to run, but the most expensive to run is more than three times this amount at £87. Our energy cost calculators show you just how much an appliance will cost you to run in a year and over its lifetime.
