5 of the most energy-guzzling household appliances

Posted on 10 November 2015

With the average household in the UK containing 40-50 electrical appliances, making sure you’re using all of them as efficiently as possible can be pretty tricky. So, to make life a little bit easier, we’re identifying five of the most energy-hungry pieces of technology in your home and a few ways you can stop them draining your finances.


TVs can be one of the most electricity guzzling appliances in your home, with high definition plasma screens using more energy than standard definition equivalents. In fact, the larger the TV, the more energy it will use to run, so a smaller screen will mean a smaller energy bill.

If you can’t bear to stare at anything less than forty inches however, there are a couple of other ways to stop your TV racking up your energy bill. LCD flat screens are much cheaper to run than plasma screens, so is something to consider when buying a new TV. Switching your electronics off on the wall instead of leaving it on standby can save you £80 per year and making sure you turn your TV off when you leave the room will also have a significant impact on your bill.

Fridges and Freezers

Since these appliances are left on 24/7, they are easily one of the worst energy-using offenders. To ensure your fridges and freezers use as little energy as possible, make sure their seals are intact and avoid overloading them. The recommended temperature setting for fridges is 5˚C and regularly defrosting your freezer can save you £100 per year.

Electric Heaters

Regularly using an electric heater will have a big impact on your energy bill. Just switching it on for two hours per day will end up costing you £17.36 a month, or £208.33 a year, which is one outgoing we could probably all do without. Extra jumpers and hot water bottles are much cheaper alternatives for keeping yourself warm, or you could consider a few long term solutions such as cavity wall and roof insulation.


Surprisingly, on average dehumidifiers cost more to power than fridge-freezers, building up a massive annual running cost of £76. Often used to treat problems with mould or damp, using a dehumidifier to regulate a room’s humidity can be costly. If possible, use other methods such as opening windows to keep areas well ventilated, as well as spreading out towels and shower curtains to dry to stop them retaining moisture. 

Tumble Dryers

Tumble dryers need a lot of energy to run but they’re also one power-hungry appliance that’s easy to avoid. Although it may take a little longer, drying your clothes outside or making the most of your radiators are quick ways to reduce your energy bill. Depending on your machine, avoiding using your tumble dryer can save anything from £39 - £139 per year which is definitely money that could be better spent elsewhere!

With all household appliances and technologies, choosing a model with a better energy rating will help you save money on your energy bill. So, next time you think about ordering a new electrical item, consider how much a more efficient model could save you in the future!
