Top 5 most energy consuming appliances

Which appliances make up the most of your bill and how to bring that number down.

1- Wet Appliances 14% 

Appliances such as your washing machine and dishwasher account for 14% of a typical energy bill. The power needed to heat the water that they use pushes up their consumption, making them energy-hungry household appliances. 

TIP: If you are on our Super Economy 12 tariff and use these appliances during your low rate, you can save more than half the cost of a wash! 

2- Cold Appliances 13% 

Like your fridge or freezer, these are switched on 24 hours a day, seven days a week and they account for around 13% of the average household’s energy bill. As these appliances need to stay on all the time, they’re continually using power to maintain a constant temperature. 

TIP: Make sure they are set to the right temperature and if they are fully stocked, they are much more efficient. 

3- Personal Electronics
We are all reliant on consumer electronics – from laptops to TVs to game consoles - accounting for around 6% of your energy bill. 

Don’t leave them plugged in – they will be using energy even when you’re not using them. The average household spends up to £65 a year powering appliances left on standby.

Top Tip: Switch off standby - You can purchase standby savers that allow you to turn all your appliances off standby in one go. Some come with timers and others come with a single off-switch.  


4- Lighting
Lighting takes up around 5% of an average home’s total energy bill. If the average household replaced all bulbs with LEDs, it would cost about £160 and save around £55 a year on bills. Of course, that depends on how many bulbs you have in your household. But on a 'per bulb basis', switching to LEDs could save you £15 per year, per bulb. 


5- Cooking  
Around 4% of your energy bill is spent on powering kitchen appliances such as your hob and oven. 

Top Tip: Try an alternative to your oven - Using an Air fryer to cook two or three meals a week could save you up to £250 a year.  Microwaves are more efficient than ovens as they only heat the food and not the air space inside.
