The 10 most expensive appliances to run – and how to cut costs


ENERGY bills are set to soar by £1,657 in October and it’s worth knowing which of your appliances is setting you back.

The current energy price cap is £1,972, but forecasts in recent weeks suggest it will hit £3,628 by October and £4,538 in January.


You Could Save Money Across Your Home If You Know How Much Your Appliances Cost

We’ve already looked at the worst devices to leave on standby, and the vampire devices that suck the most power.

But Boiler Central has revealed the top ten appliances that will hurt your back pockets with heavy use.

You too can calculate the running cost of an appliance by doing a simple equation.

The equation is: Cost = power (kilowatt) x cost of a kWh (cent) x duration (a single meal, or over a week or a month.)

We’ve already looked at how much it costs to run an electric heater, the costs of running an electric fan, and how much your spa adds to your bills.

Here are 10 appliances that are costing you the most and the least in your home, followed by tips on how to cut those costs.

Dishwasher – £10.30 per month

A dishwasher is one of the most energy-intensive appliances in the kitchen and costs UK households an average of £10.30 a month.

However, there’s a lot of debate about whether it’s cheaper to wash your dishes by hand.

In fact, most modern dishwashers use far less water than hand washing – so they should be cheaper to run and better for the environment.

Boiler – £78 per month

It’s no secret that our central heating systems are expensive to run, but apparently it’s the most expensive in the long run, costing homeowners an average of £78 a month.

You can often reduce your boiler costs by adjusting the flow temperatures of your hot water and central heating. A thrifty saver saved £90 over six months with this trick.

Fridge freezer – £13 per month

The energy rating of your fridge freezer will affect the cost of running it 24/7 each month.

Those with older fridges and less efficient D-rated fridge-freezers could pay up to £13 a month to run the appliance.

Those with more energy-efficient Class A appliances will pay up to £7 a month.

Of course, you can’t just unplug your freezer to save money, but there are other ways to reduce the running costs of your fridge-freezer.

Kettle – £9.60

Your need for a hot cup of tea may be costing you more than you initially thought.

On average, it will cost you £9.60 a month to use your kettle for 15 minutes a day.

To keep costs down, it’s always wise to boil only the amount of water you need.

Laptop – £1.56 per month

Laptops are inexpensive to use when you consider how much it costs the average household per month.

At £1.56 a month, it may surprise you to know there’s still more to be saved.

While the device will only use around 3 watts of power in standby mode, leaving them idle will cost you an extra £0.13 per day, or up to £4.87 over a year.

Unplug your laptop when not in use.

Microwave – 1.60 per month

Microwaves are a kitchen essential for many and they only cost £1.60 a month if you were to use them for 10 minutes each day.

Energy Saving Trust claims that a microwave oven is more energy efficient than a traditional gas or electric oven.

This is because microwaves only heat your food and not the air space inside it, which means they use less energy to cook your dinner.

However, Energy Saving Trust also states that a microwave is one of the appliances that will “draw electricity” when left on standby.

Turn it off at the outlet and you could save money on your energy bill.

Mobile phone – £0.44 per month

Your mobile phones are usually the cheapest electrical devices to run in your home – costing around 44 pence a month to charge and use.

And while keeping our devices powered doesn’t cost as much as you feared, there’s no point wasting money on leaving them plugged in when you don’t need them.

And remember that even if you don’t have a phone connected to it, your charger will still draw power if you leave it plugged in.

Oven – £9.36 per month

Ovens are expensive – costing on average almost £10 a month for daily use.

Electric ovens tend to be more energy efficient and do better in cost-cutting tests.

If possible, consider using the microwave or air fryer instead as they are much cheaper to run.

Television – £3.45 per month

Telivisions are expensive to use compared to other technologies – costing an average of £3.45 per month.

And there are always savings to be made.

Luckily, there are a few nifty ways to save money by getting your TV working so you can sit down and watch your favorite series guilt-free.

You could cut your costs by £12 a year if you stopped leaving the device on standby when not in use.

Washing machine – £14 per month

For a typical family of four, using a washing machine can cost you £14 a month, or £168 a year.

As with clothes dryers, the cost largely depends on the make and model of your machine.

A typical UK household does 270 loads of laundry a year, so making sure you have a machine that works for you is a must.

Other Ways to Cut Costs

Myles Robinson, energy expert at Boiler Central, said: “The most energy-intensive appliance in your home is your boiler and with energy prices at an all-time high, switching to a new energy-efficient boiler is the best way to cut down on your energy bills.”

Myles said on the issue of expensive old boilers: “If your gas boiler was installed before 2005, chances are it’s a non-condensing boiler.

Older condensing boilers tend to be less than 60% energy efficient, which means they waste up to 40% of the energy you’re billed each month.

That said, replacing your boiler can be expensive, and there are other less expensive ways to lower your energy bills.

Installing a smart thermostat can cut your energy bill by up to £75 according to Myles.

Myles said: “These devices sense how much energy you need to heat certain rooms and can also be programmed to turn on and off at the most relevant times.
