1. Flat Screen Plasma TV

Surprisingly, a flat screen plasma TV ranks as the most expensive appliance, costing on average a huge £95 per year to run (658 kWh).

Since a TV is not an essential item and is not constantly running, this amount can vary greatly depending on how much you use it.

Tip: If you are looking for a more efficient TV, LCD models use on average two thirds less energy than Plasma flat screens.

2. Washing Machine

Using a washing machine on temperatures above 30 degrees could be using 2.5 kWh per hour long wash (not including the use of a tumble drier).

If you consider how many times you use it each week this can soon add up at around 35p per hour, with the average home spending £23 per year (163 kWh).

Tip: Wash your clothes at 30 degrees as this will use less energy, reducing both emissions and your electricity bill.

3. Tumble Dryer

Tumble dryers are notorious for draining energy and actually cost a lot more to run than washing machines themselves, at an average of £55 per year (392 kWh).

If you use your tumble dryer after every wash you could see your bills skyrocket in no time.

Tip: During the warmer months try to dry as much of your laundry as possible outside or on drying racks – even if you can only reduce tumble dryer use over spring and summer it will still make a huge difference to the annual cost.

4. Dishwasher

Although the debate is still out about which is most efficient; dishwashers or hand washing, many people use dishwashers as they are convenient and save time. The average UK household uses 296 kWh and spends £42 each year powering their dishwasher.

Tip: Make the most efficient use of your dishwasher by only running it when it is full.

5. Electric Shower

If you use an electric shower to heat your water you could be using a lot more energy that you thought.

According to Sust-it, depending on the power rating of your model, you could be using between £64.10 (455 kWh) and £92.31 (655 kWh) per person per year for a 10 minute shower each day.

Tip: Reducing your shower by just one minute a day can save you up to an average of £9.23 per year.

6. Fridge-freezer

An essential appliance to most households, the fridge-freezer earns its place in the list not because of a high power rating but because it is constantly running. A typical fridge freezer can use on average 427 kWh per year – around £62.

Tip: If you can, invest in a new fridge freezer with a rating of A+ or above (since July 2012 all new models must have a rating of at least A+) as this will reduce the amount of energy it requires to run.

7. Electric Ovens

An average UK household will spend around £46 (317 kWh) per year on a cooker with an electric hob. Electric ovens definitely have benefits including even heating and easy cleaning, but they do tend to cost more to run that gas ovens.

Tip: Don’t open your oven door when cooking as this allows the heat to escape, meaning the oven has to get back up to that temperature.

Instead keep the door clean so that you can look inside to check on your food.

8. Desktop PC

Unlike laptops, which only cost around £4 (29 kWh) a year to run, desktop PC’s can guzzle up 166 kWh a year! That’s around £24 – although this will vary depending on how often you use your computer and how old it is.

Tip: Don’t leave your desktop or other computer devices on standby, as this actually uses power and can soon add up.

9. Printer With Fax

Printers with a fax element are almost as expensive to run as your desktop itself, using 160 kWh and costing £23 per year. When you add in the price of repurchasing ink and paper, printing can be expensive business!

Tip: Keep your printer unplugged and only switch it on when you actually need to print or receive/ send a fax.

10. Electric kettle

In the UK the majority of use our kettles at least once a day – we do love making tea after all.

A recent study found that three-quarters of us overfill our kettles, using more energy than necessary. On average a kettle uses 167 kWh per year and costs £24.

Tip: Fill your kettle with only the amount of water you intend to use – this should also make it boiler faster.
