Your fridge freezer is likely to be one of the worst appliances for guzzling energy in your kitchen.
But if you're looking to cut down your costs, there are some things you can do to keep it running as smoothly as possible.
Energy experts at Uswitch recommend cleaning behind your fridge freezer regularly to keep it working properly.
Dust on the condenser coils can prevent your appliance from cooling as quickly as it should, meaning it needs to work extra hard to keep your food cold.
As well as cleaning your fridge, you should make sure the freezer compartment is defrosted frequently so there isn't a build up of ice.
Again, a big build up of ice puts more pressure on your appliance.
A spokesperson from Uswitch told The Mirror: "Clean behind your fridge and freezer to help keep them cool and working as efficiently as possible.
"Running a modern fridge for a year costs just over £28. So if its efficiency is reduced by 10%, it could add £2.80 to your annual bill."
You should also avoid leaving the fridge door open, as this is a waste of energy too and makes the appliance work harder.

For every minute that a fridge door is left open, it takes roughly ten minutes to cool back down.
Finally, the team at Uswitch recommend keeping your fridge not too cluttered so that the air can still circulate and the appliance can work as efficiently as possible.
"You should aim to keep your fridge full if you can - it will use less energy when it’s well stocked, but not too full," said Uswitch.
Many households are looking for ways to lower their energy bills after the regulator Ofgem confirmed it was hiking its price cap by an unprecedented £700.
For those on a default tariff who pay by direct debit, the price cap has gone up from £1,277 to £1,971 - a rise of £693.
Prepayment customers have seen a bigger jump, with their price cap going up by £708, from £1,309 to £2,017.
The price cap limits how much households can be charged for each unit of gas and electricity they use.
For other ways to lower your bills, we've looked at whether it is cheaper to use an electric heater or gas radiators.
In general, an electric heater is an expensive way to heat your home and you're normally better off using your radiators.
However, there may be times when it is cheaper to run an electric heater.
For example, if you're only heating one room for a short period of time and the rest of your central heating is turned off.
We've also looked into whether you're better off using a microwave or regular oven when cooking, to keep your costs down.
Cooking a baked potato in the oven would cost around 27p compared to 3p in the microwave.
When it comes to the best way to use your kettle, you should only fill it up with as much water as you need.
Many of us are guilty of not sticking to this rule - and it could be adding £87 to your energy bill.
