There are five every-day home appliances probably adding hundreds to your bills each year.
Washing machines, ovens, fridge freezers, dishwashers and tumble dryers are the biggest energy guzzlers, according to consumer group Which?
Most householders, understandably, wouldn't want to give these up but thankfully there are simple ways you can potentially save up to £300.
The news comes as homes across the country are now spending, on average, an eye-watering £2,500 a year on bills.
Emily Seymour, energy editor at Which? said: "Our research shows running costs for common household appliances - like washing machines, tumble dryers, fridge-freezers and dishwashers - have risen by nearly 60% during the cost of living crisis.
"The good news is that there are things you can do to cut back on energy costs linked to these appliances."
Here are the five big energy guzzling appliances, how much they cost to run on average and how you can save money.
Take into account that each model and how often you use it will affect how much it costs to run and how much you save.
Washing machine
A washing machine with a 9kg capacity will cost on average £77.47 a year as of April this year, Which? found.
In October 2021 it cost £49 a year.
To save money you can wash your clothes at a lower temperature. Washing them at 30°C cuts energy use by 28% compared to 40°C and saves you around £29 every year.
Unless your clothes are really dirty, they should come out clean at this temperature.
To save even more money - roughly £48 a year - turn the temperature down to 20°C, which uses 62% less energy than washing at 40°C.
Tumble dryer
There are two main types of tumble dryers, condenser or heat pump. Condensers are the big energy guzzlers costing on average a whopping £217 a year, according to Which?
A heat pump tumble dryer, meanwhile, is a much more budget friendly £69.49.
To save money Which? recommends using a heated airer instead. It found drying three 2.15kg cotton loads a week will cost around £62 a year with an average model.
That's about £8 cheaper compared to a heat pump tumble dryer and £155 less than a condenser.
Alternatively you can turn down the cycle heat of the tumble dryer or give it a clean to make sure it's running efficiently.
Obviously you could hang your clothes on a line outside or on a clothes horse inside, which costs nothing, but that obviously depends on what space you have at home.
Dishwasher
Dishwashers are a convenient way to get your dishes clean and actually use less water than washing up by hand.
But they are big energy consumers and cost on average £94.86 a year to run.
To save money just go to the settings and change to the energy-saving setting or eco program. It will take longer but uses around 30% less energy. This should save you about £28 a year.
If you're looking to buy a new dishwasher, try and buy one with a better energy rating.
A rating system from A to G will show you how efficient an appliance is with A the best and G being the worst.
Using an inefficient dishwasher could be adding £500 to your energy bills over its lifetime, Which? has previously said.
Oven
A built-in oven costs a household on average £77.02 per year to run, said Which?, compared to £48.71 in October 2021.
To save money, you can cook in bulk or choose an alternative device, such as an air fryer.
Air fryers' popularity have surged since the rise in energy costs as they're often cheaper to run.
A 2000w air fryer for example will cost around 68p to run per hour compared to a 2,500w oven that costs around 85p an hour.
If someone used an air fryer for an hour a day every day of the year it would cost them on average £248.20 in electricity, based on a floor unit price of 34p per kilowatt.
An oven meanwhile would cost £310.25 for the same amount of use, £62 more.
It's worth noting, however, that air fryers aren't always the cheapest option, as highlighted by Money Saving Expert's Martin Lewis.
He explained that if you're cooking a large meal like a roast, it's cheaper to use an oven, while something smaller might be cheaper in an air fryer.
Fridge-freezer
Most households wouldn't go without a fridge-freezer, but they are pretty costly at around £139.90 a year.
An freestanding American model can cost even more at roughly £200 a year to run.
To save costs ensure the doors on it aren't open too long. Leaving doors open will cause the air inside to warm and the appliance will have to work harder to cool down again.
Putting hot food inside can also cause the air to rise, so allow all food to cool first.
You can also save money by cleaning behind the unit to ensure the coils don't clog up and it can work as efficiently as possible.
Finally, buy the most energy efficient fridge-freezer model that you can.
