The cost of living crisis has us all wondering how we can save money on our energy bills.

So it's useful to know which household appliances are the most energy-efficient, and which are costing us the most money.

The energy experts at boiler firm Hometree have crunched the numbers and revealed the costs of running your home appliances, by looking at which ones use the most energy, and what you can do for cheaper alternatives.

1. Dishwasher - £1.12 per 90 minute cycle

The majority usage on your energy bills will come from the wet household appliances, such as dishwashers and washing machines.

The average dishwasher cycle lasts around an hour and a half, but some lower quality ones can run from two to four hours.

Running a dishwasher is one of the most expensive household appliances, using around 3.3 kWh of energy.

There are options for saving on your energy bills, such as making sure to only run the dishwasher when fully loaded, and investing in a grade A energy-efficient dishwasher.

The good news is that dishwashers are more time efficient, and cheaper than washing dishes by hand, which tends to use more water.

2. Washing Machine - 75p per hour cycle

Washing machines and dishwashers account for around 14 per cent of a typical energy bill.

On average, a typical washing machine will run from around 45 to 90 minutes.

A washing machine will have a similar power rating to a dishwasher, with an average rating of 2200W.

Typically, though, the running cycle for a washing machine would be shorter, therefore costing less per cycle.

To save money you should avoid half-loads and opt for a grade A energy-efficiency rating.

Some washing machines will have an eco-friendly option, which will use a lower wash and temperature, so less energy is required for heating, therefore costing you less.

3. Fridge and freezer - £3.26 per day

On average, fridges and freezers will account for around 13per cent of your household’s energy bill, according to Energy Saving Trust.

The average fridge/freezer will stay on 24/7, with a Wattage of 400, using around 9.6 kWh of energy per day.

There aren’t many options in terms of energy saving, as the nature of a fridge and freezer means they have to stay on all day.

However, you can invest in a more energy-efficient one.

4. Oven (Gas/Electric) - 34p per 20 minutes

Using your oven every day can be a real drain on power, and therefore finances.

However, if you do have to use an oven, there are ways to maximise your energy-efficiency.

For example, refrain from storing baking trays inside the oven when cooking, as they block the airflow.

Also, cleaning your oven regularly helps maintain more effective heat distribution.

A cheaper alternative to an oven would be an air fryer, which is much more energy-efficient than most convection ovens because they cook food much faster.

However, they do use electricity, which is typically more expensive than gas.

Recent research has shown that cooking in an air fryer costs about half the price of cooking in an oven.

5. Electrical appliances - 10p per hour

From TVs to laptops to game consoles; we are more reliant on consumer electronics than ever, and these take up around 6 per cent of your energy bills, according to Energy Saving Trust.

The average laptop with a wattage rating of 50 will cost you around 2p to use every hour.

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

The Northern Echo:

6. Lighting - 2p per hour

Energy Saving Trust reports that lighting will cost around 5 per cent of the average yearly energy bull.

The average lightbulb will cost you around 2p per hour, using up 0.06 kWh of energy.

This may not seem like much, but when you have several lightbulbs running all day, the numbers soon add up.

It may seem obvious, but making sure to turn your light switches off when not in use can save around £25 a year in energy bills.

You can also invest in LED lighting, which is often brighter and more energy efficient.

Switching out your incandescent bulb for LED can save you around £15 per light bulb per year.
