Energy-efficient tumble dryers


This is a great heat pump tumble dryer. With its low running costs, impressive drying results and effective condensation unit, it goes straight to the top end of our Best Buy leader board. But if you're always washing in a hurry we've found other dryers that have quicker cotton programs.


This brand has produced yet another first-class tumble dryer - it dries clothes well and keeps energy use low. It’s one of the quieter machines we’ve seen, and the condenser does a terrific job of capturing water from clothes.


This tumble dryer works with an app that allows you to control it remotely. But that's not all that's smart about it: it's so conservative with energy that it costs less than £30 a year to run. You'll also love how quietly it runs and how well it dries your laundry.


You usually have to shell out up to £1,000 for an A+++ rated tumble dryer, but this model offers low ongoing running costs without the extortionate upfront price. It's also great at drying, easy to use and doesn't leave your clothes too creased.


This tumble dryer is worth considering as it has the very cheapest running costs of every dryer we've tested. Clothes are dried exceptionally well, plus it's user friendly and quieter than the average dryer.

And here are three tumble dryers to avoid 

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.

Don't Buy tumble dryers


You might be tempted to buy this Best Buy tumble dryer, but if ongoing energy costs are your main concern then you should steer well clear. Its large 10kg drum can fit a lot of clothes inside, but it will cost you over four times more to run than other dryers we've tested.


This vented dryer is good at getting your clothes dry, but it falls down in several other areas, including how noisy its programs are and how much it costs to run. Make sure to avoid it if you're trying to reduce your monthly energy bills.


You'll get nicely dried clothes and quick programs with this condenser tumble dryer, but that's not a good enough reason to buy it. Its condenser is next to useless, so you could end up with condensation and damp in your home, plus it's really expensive to run.

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. Currently, there is a limited choice on the market and they tend to be fairly expensive to buy. But tumble dryers with heat pumps cost less than half to run than others and, with more companies investing in the technology, prices are already starting to fall.

Gas tumble dryers

Gas is a cheaper fuel than electricity, making gas-powered tumble dryers a good energy-saving alternative to 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.
