Worst energy efficient tumble dryers
Without reading our expert reviews, you run the risk of buying a tumble dryer that's let down by a poor energy efficiency rating. Buying a Which? Don't Buy could see you spending more on your annual energy bills than you'd like. Below, we've rounded up some Don't Buy condenser tumble dryers to steer clear of.
- 46%£300.00
Although it dries accurately, this dryer is noisier than most. But the biggest problem is that the condenser isn’t efficient and allows damp air from your laundry to leak out into the room - where it can cause steamy windows and condensation. And energy use is very high.

Although this machine dries accurately, it’s not particularly quick, and uses a huge amount of energy to dry clothes. Add the fact that it’s noisy and tricky to maintain, and you can see why it failed to impress our experts in the test lab. That's why we've made it a Don't Buy.

Decent drying isn't enough to redeem this incredibly noisy and expensive-to-run machine. It has a large capacity and won't crease your clothes too badly, but there's no escaping it's huge running costs of over £120 per year.

Heat pump vs gas tumble dryers: what's the difference?
Tumble dryers are given EU energy labels - these range from A+++ for the most energy efficient, to G for the least. The average rating, C-class, may sound fine - but an A-rated dryer would cost you roughly half as much to run. Some tumble dryers have special features to help you save energy. Look out for sensor drying; models with this feature automatically detect how wet your laundry is and stop when it’s dry.
Heat pump tumble dryers
Condenser tumble dryers with heat pump technology can lead to big savings on your energy bills. They are currently the most expensive tumble dryer type to buy, with the average price at £647, but tumble dryers with heat pumps can cost less than half to run than other types.
Check out our best heat pump tumble dryers and expert advice, or read our heat pump tumble dryer reviews to see which are Energy Savers.
Gas tumble dryers
Gas is a cheaper fuel than electricity, making gas-powered tumble dryers a good energy-saving alternative to most electric tumble dryers, particularly when they're vented. However, gas dryers are expensive to buy and need to be installed by qualified Gas Safe engineers, which can also be costly. Gas dryers also need to be placed somewhere near a vent or a window, so the hose can vent humid air outside.

Tips to get more from your tumble dryer
Choose a more efficient tumble dryer
Doing so is a sure way to keep your bills down.
Fill your tumble dryer
Make sure you fill your tumble dryer to its maximum capacity every time you use it.
Clean the lint filter
Do this every time you use the machine. A blocked filter prevents the hot air from circulating freely, meaning clothes take longer to dry. On some models you'll need to clean the second filter. This is essential on some heat-pump models.
Clean the heat exchange
Get more from your condenser dryer by cleaning the heat exchange. The manufacturer will advise on how often this needs to be done.
Fasten the stoppers of your duvet covers
This will stop smaller items of laundry getting trapped inside and remaining wet.

How much do tumble dryers cost to run?
Go to the tech specs tab on our tumble dryer reviews to see how much each machine costs to run per year. Our energy calculations are based on each tumble dryer being used three times a week to wash a 70% full load of cottons. You can also check our running cost tool to find out how much a tumble dryer would cost to run over its lifetime
