Understanding which appliances use the most electricity in your home is key to managing your energy bills effectively. This article looks at seven common household appliances that can significantly impact your electricity usage. You can also dig deeper into their energy consumption levels and learn some electricity-saving tips to use them more efficiently.
What Appliances Use The Most Electricity?
Several household appliances significantly contribute to your electricity bill. Below is a list of the biggest energy consumers in your home, along with some useful energy-saving tips.
| Average Power Rating | Percentage of Energy Usage | |
|---|---|---|
| Heating/Cooling Systems | 75 to 960 watts | 20 to 60% |
| Water Heaters | 3,500 watts | 4 to 7% |
| Lighting | 5 to 100 watts | 6 to 15% |
| Fridges and Freezers | 100 to 150 watts | 5 to 16% |
| Cooking Appliances | 200 to 1,500 watts | 7 to 14% |
| Washers and Dryers | 500 to 1,200 watts | 3 to 15% |
| Televisions, Laptops and Games Consoles | 50 to 200 watts | 3 to 6% |
Heating/Cooling Systems
All heating and cooling systems consume significant energy to maintain indoor comfort. To conserve electricity, consider using a timer or smart thermostat that can automatically switch systems off when they’re not needed. For heating, set your thermostat to the lowest comfortable temperature; for most people, this is between 18°C and 21°C. Lowering the thermostat by just 1°C (e.g., from 22°C to 21°C) can save approximately £90 annually in Great Britain and £105 in Northern Ireland. During warmer months, set air conditioning to a comfortable 24-26°C to optimize cooling costs. You can also explore practical strategies on how to save on your gas bill in winter to manage expenses during colder weather.
Water Heaters
You use electric water heaters for showering, laundry, washing dishes, and other activities, collectively contributing to monthly energy consumption. Understanding what appliance uses the most electricity might be helpful in taking care of the energy usage. You can make use of tankless water heaters that heat water only when you need it. An eco-friendly water heater can do the trick too; it uses renewable energy to run.
Lighting
Lighting accounts for a substantial part of electricity usage, especially incandescent bulbs. The high energy consumption of those bulbs also result in increased greenhouse gas emissions. Moreover, they generate heat that raise indoor temperatures, increasing the demand for cooling. LEDs would be a better choice since they are more energy-efficient and can last longer.

Fridges And Freezers
Among what uses a lot of electricity in your home, fridges and freezers stand out as they run continuously to keep your food and beverages cold. Over time, this constant energy consumption adds substantially to your monthly energy charges.
To save energy with your fridge and freezer, keep them at the right temperatures. More specifically, set the fridge temperature to 1.7 to 3.3°C, and the freezer should be at -17.8 °C. Besides, clean the coils of each on a regular basis to avoid overloading and ensure good air circulation around them.
Cooking Appliances
What appliances use the most electricity when turned off? Cooking appliances like kettles, ovens, and microwaves can be among the biggest energy drains due to standby power consumption. Even when not actively in use, they draw energy if left plugged in, increasing energy costs. This is especially true for microwaves and other appliances with clocks or digital displays, which continuously consume small amounts of power.
For restaurant owners, energy-saving strategies can significantly reduce utility bills. Be sure to unplug appliances when they aren’t needed or consider using a smart power strip to fully cut off power to devices in standby mode, preventing “phantom” energy use that can add up over time. Additional insights on how to save energy in a restaurant provide practical steps to help further lower energy expenses.
Washers And Dryers
The heating elements in washers and dryers make them among the top energy-consuming appliances. Hence, it would be best to use a cold water setting whenever possible. If possible, air-dry your clothes to reduce energy consumption on those devices.
Televisions, Laptops And Game Consoles
Despite being relatively low-power electronics, televisions, laptops, and game consoles account for about 3 to 6% of your energy bill. You should make it a habit to turn them off completely when not in use and use devices with high energy efficiency ratings.
How Much Do Appliances Cost on an Electricity Bill?
To work out how much certain appliances contribute to your electricity bill, you can use this easy calculation:
Monthly Usage (kWh) x Electric Rate (£/kWh) = Monthly Cost
- Find Your Rate per kWh: Check your latest electricity bill for the rate per kilowatt-hour (kWh) you’re paying. For example, if it’s £0.34 per kWh, use that in your calculation.
- Estimate Appliance Usage: Multiply your electricity rate by the estimated monthly usage of each appliance. For instance, if your washing machine uses around 30 kWh a month, here’s how it would work out:
30 kWh x £0.34 = £10.20/month
In this example, running the washing machine would add roughly £10.20 to your monthly bill. For a more accurate idea of energy costs, you might want to use a smart meter or a plug-in power usage monitor to track real-time consumption. Certain appliances, especially those with variable settings, can fluctuate in usage, so monitoring can give a more complete view over time.

FAQs
1. Do fans use a lot of electricity?
No. Fans consume about 50 to 100 watts per hour, significantly less than air conditioning units, which use around 700 watts per hour.
2. Can I leave the AC on all day?
Yes. Working all day doesn’t cause any damage to the AC, but it will put pressure on the cooling system and lead to costly electricity bills.
3. Does leaving a kettle plugged in draw electricity?
Yes. Even when you have turned off the kettle, it can draw about 30 watts of electricity per hour.
4. Which appliances use the least electricity?
Ovens, space heaters, and hair dryers consume very few kWh. Some modern refrigerators are energy-friendly, using only 30 kWh per month.
