1. Dishwasher – £1.12 per 90 minute cycle

The average dishwasher cycle takes about an hour and a half, and running a dishwasher is one of the most expensive household appliances, consuming around 3.3 kWh of energy.

There are options to save on your energy bills when it comes to washing up. First, invest in an energy-efficient Class A dishwasher. Second, make sure you only run the dishwasher when it’s fully loaded.

2. Washing machine – 75p cycle per hour

Washing machines and dishwashers account for approximately 14 percent of a typical energy bill. On average, a typical washing machine will run for around 45-90 minutes.

On an average 2200W washing machine, the appliance will use around 2.2kWh of energy if it runs for an hour, which will cost around 75p. Again, avoid half loads and go for a Class A energy efficiency rating. Some washing machines will have an eco option, which will use a lower wash and temperature, so less energy is needed for the heating, which will cost you less.

3. Fridge and Freezer – £3.26 per day

On average, refrigerators and freezers account for approximately 13 percent of your household energy bill, according to Energy Saving Trust. The average fridge/freezer will stay on 24/7 with 400 watts of power, using around 9.6 kWh of energy per day.

There aren’t many options when it comes to energy saving, as the nature of a fridge and freezer means they have to be on all day. However, you can invest in a more energy-efficient model. Each household item will have a rating based on its energy efficiency, so look for those with grade A – it will save you money in the long run.

Washing machines cost around 75p per cycle

4. Oven – 34p per 20 mins

The average power of an oven is about 3kW, which means it uses about 1kWh if it runs for about 20 minutes, or about 34p.

Daily use of your oven can be a real waste of energy, and therefore money. However, if you must use an oven, there are ways to maximize your energy efficiency. For example, avoid storing baking sheets inside the oven during cooking, as they block air circulation. Plus, cleaning your oven regularly helps maintain a more efficient distribution of heat.

A cheaper alternative to an oven would be an air fryerwhich is much more energy efficient than most convection ovens as they cook food much faster.

An air fryer is similar to an oven in that it cooks and roasts. The main difference, however, is that the heating elements are only located on the top and are accompanied by a large, powerful fan. The average power of the air fryer is 1 kW, which means that using an air fryer for about ten minutes would consume up to about 0.16 kWh of energy. It will cost around 5p on average, making it the most affordable way to cook.

5. Electrical Appliances – 10p per hour

From televisions to laptops to game consoles; we depend on consumer electronics more than ever, and these account for around 6% of your energy bills, according to Energy Saving Trust.

A typical 50 inch plasma TV will have a power rating of around 300W and will cost you around 10p per hour to operate, using 0.3kWh. The average laptop with a power rating of 50 will also cost you around 2 pence to use every hour.

Turn off your laptop when not in use

There are things you can do to cut costs when watching TV, such as lowering the brightness slightly, setting a sleep timer, and turning off the outlet when not in use.

6. Lighting – 2p per hour

Energy Saving Trust reports that lighting will cost around 5% of average annual energy. The average bulb will cost you around 2 pence per hour, consuming up to 0.06 kWh of energy. It may not seem like much, but when multiple bulbs are running all day, the numbers add up quickly.

It might sound obvious, but making sure you turn off your light switches when not in use can save you around £25 a year on your energy bills. You can also invest in LED lighting, which is often brighter and more energy efficient. Replace your incandescent bulb with an LED can save you around £15 per bulb per year.
