Washer-dryers: Washer-dryer energy costs
Which? doesn't only test washer-dryers for how well they clean and dry - we also measure the hidden costs of running a washer-dryer so you don't get a nasty surprise when you open your electricity bill.
Through our independent lab tests, we've discovered that buying an inefficient washer-dryer could add around £70 to your electricity bills each year. You'll find running costs and energy use ratings in each of our individual washer-dryer reviews - but for an at-a-glance guide to washer dryer energy costs, use the running costs tool below to find out how the costs add up over the years.
Washer-dryer running costs
Energy saving washer dryers
All washer-dryers have official EU energy labels which can help you choose a greener model. Washer-dryers are ranked A (most efficient) to G (least efficient) - but these labels don’t give you the full picture. They don’t tell you how the running costs of the appliance add up over the years - only Which? tests can tell you this.
Which? tests reflect how you use your machine. We look at annual running costs on the most commonly-used programme in the UK - a 40°C cotton cycle - and drying running costs based on energy per kilo of washing on four programmes.
But however energy-efficient your washer-dryer is, its dual functionality makes it one of the least reliable types of all home appliances. Three in 10 washer-dryers are likely to have a problem that needs repairing in the first six years, compared to one in ten tumble dryers.
Reduce the likelihood of choosing an unreliable model by checking our washer-dryer reliability survey results – based on the experiences of thousands of Which? members.
