Compare your kitchen appliances' energy efficiency rating

appliance energy efficiency

Households in this day and age have an increasing amount of electrical goods, including smartphones, laptops, tablets, an electric toothbrush, to name a few, but some of your kitchen appliances cannot be charged and thus need to be on at all times. Below we will see just how much electricity you consume to keep your kitchen appliances running; it may make you think twice the next time you turn your appliances on.

Energy Efficient Appliances

You have probably seen an energy efficiency rating chart on your fridge freezer or on your oven that will probably have some variation of an A marked on it. You can also have ratings on your TV, PC and oven.

This rating system is the product of a European Union delegation that adopted a rating structure from the American standard called the energy star rating.

Energy star is an international standards company for any energy efficient home appliance. The products they recommend use 20%-30% less energy than the standard registered appliances.

So, when searching for your new appliance, don’t just check the price: also check the energy rating, as it will have a positive impact on your energy costs.

Washing Machines

On a normal cycle you will use around (or more than) 2,000 litres and a year to do your washing, and if you are a family of four or more, it could be twice that.

When you put on a normal wash, you will use between 35-55 litres of water every time.

To save money on your water bill, check to see if you have an eco or quick wash setting so that your load is finished quicker and uses less energy.

A typical washing machine will use around 0.5kWh on a standard setting, using around 1088 kilowatt hours annually.

You will generally use more kilowatt hours if you have a larger sized drum or use sophisticated settings.

Top Fact for Saving EnergyWhen buying a new washing machine, look for an ‘eco cycle’ or ‘quick wash’. This setting will use less water, lower temperatures and will run for less time, therefore using less electricity. The new Samsung eco bubble lets you wash at 15 degrees for 20 minutes, with the same results as a 60-minute wash. This high efficiency feature is a big help when it comes to reducing your energy consumption.

Tumble Dryers

With the weather we have in England, a tumble dryer can be a necessary household appliance to keep your clothes dry.

The average tumble dryer on the market, with an energy rating of A, can cost you £50-£60 a year to run, unlike a dryer with an energy rating of C, which can cost up to £100 a year or more! That is quite the difference! Don’t be mistaken: if you use your tumble dryer a lot, it will be the most expensive appliance in your kitchen. In order to have your tumble dryer run as efficiently as possible, it's important to be on top of its maintenance, such as making sure that its ventilation system is cleaned yearly.

Average usage per cycle: 1.92 - 5.18 kWh
Average annual consumption: 230 - 638 kWh

Oven and Cooker

Your cooker is the centre of attention in many kitchens, being used all the time to cook your favourite meals.

There are many different types of powered cookers out there, including gas powered hobs, electric fan ovens or a gas powered hob.

Some older models have one electric hob and three gas powered hobs with an electric oven, so determining how much you spend on your cooker can be difficult.

Electric ovens can vary in energy use from 0.6-1.00 kW and accompanied with an electric hob, which can run from 0.70 to 1.5 kW.

That can take the hob’s annual consumption (if you are using it for one hour every day) to over 700 kWh. That is close to a quarter of the average home energy consumption for a residental household in the UK.

Gas powered hob and ovens tend to be cheaper, but are less favoured than electric cookers due to their functionality. Based on an hour of use, gas ovens use around 1.52 kWh (of gas) and a gas powered hob about 0.9 kWh.

Fridge Freezer

Check the energy rating when buying a fridge.

You might think that you waste a lot of energy with your fridge freezer because you leave it on all the time, but you would be surprised at how little energy it uses for cooling compared to other appliances you have.

One of the highest consumers of electricity is an american-style refrigerator at 420 kWh annually.

A normal sized fridge freezer will be from 280 - 350 kWh if it has an energy rating of A or above.

Smaller fridges or an under-counter fridge help to save energy because they consume considerably less electricity over the year, starting at around 109 - 190 kWh. If you have a separate freezer or an under counter freezer the electricity consumed on a yearly basis goes from 170 - 210 kWh.


A key appliance in any kitchen, if you're lucky to have one, dishwashers use up to 12 litres of water per cycle and over 2500 litres a year, taking up well over 250 kWh annually in electricity.

Save on electricity by only washing when your dishwasher is full, reduce the temperature and select a quick cycle.


Getting your food heated up quickly in a microwave saves you a lot of time and it can be a cheap way to do your cooking.

Microwaves now come with ovens that use less electricity than normal cooker ovens. A normal microwave will use 50 - 150 kWh of electricity a year.


Electric kettle

We make a lot of tea in the UK, so the kettle is always being boiled to make your favourite cuppa’.

To boil 1.5 pints you use about 1 kWh of electricity, so 1.5 pints of tea a week will use 52 kWh a year. You can save on your electricity by boiling only the water you need, less water means less electricity.

Here are some other appliances you can find in your home and how much electricity they consume:

Coffee machine
  1. Slow Cooker 1 kWh (per hour)
  2. Iron 0.5-1 kWh (per hour)
  3. Coffee Machine 30-32 kWh (annually)
  4. Toaster 20-22 kWh (annually)
  5. Light Bulb 1 kWh (based on energy efficient lighting lasting for 40 hours)
