Quick answer: A standard vented or condenser tumble dryer uses about 4.0-4.5 kWh per full cycle, costing roughly £1.00-£1.10 per load in the UK (at 24.5p/kWh) or $0.68-$0.77 in the US (at 17c/kWh). A heat pump dryer uses only 1.5-2.0 kWh per cycle – less than half the cost. Use the calculator below to get an exact figure for your machine.

How Much Does It Cost to Run a Tumble Dryer?
Cost Per Cycle = kWh Used Per Cycle × Electricity Rate per kWh
Tumble dryers are one of the most expensive everyday appliances to run because they use a resistive heating element (or, in heat pump models, a more efficient refrigerant cycle) for 60-150 minutes at a time. The type of dryer you own makes a much bigger difference to running cost than almost any other appliance in the house.
Tumble Dryer Running Cost by Type
| Dryer Type | Typical Energy Use | Cost/Cycle (UK, 24.5p) | Cost for 4 Loads/Week/Year (UK) |
|---|---|---|---|
| Vented | 4.0-4.5 kWh | £0.98-£1.10 | £204-£229 |
| Condenser | 4.2-4.8 kWh | £1.03-£1.18 | £214-£245 |
| Heat Pump | 1.5-2.0 kWh | £0.37-£0.49 | £77-£102 |
A heat pump dryer typically costs 40-70% more to buy upfront but uses well under half the electricity of a vented or condenser model – most households recover the price difference in energy savings within 2-4 years of average use.
6 Ways to Cut Your Tumble Dryer Bill
- Use the highest spin speed on your washing machine first – a faster spin removes more water mechanically, cutting drying time (and cost) significantly.
- Only run full loads – drying a half-empty drum wastes almost as much energy as a full one.
- Use the moisture-sensor “auto” cycle instead of a fixed timer – it stops as soon as clothes are dry instead of over-drying.
- Clean the lint filter every cycle – a clogged filter forces the machine to run longer and hotter to dry the same load.
- Line-dry or airer-dry when possible – even drying just the bulkiest items (towels, jeans) by other means cuts total dryer cycles per week.
- Consider a heat pump model at replacement time – it’s the single biggest lever for reducing long-term drying cost.
FAQs
Is a heat pump tumble dryer really cheaper to run?
Yes, significantly – a heat pump dryer typically uses 1.5-2.0 kWh per cycle compared to 4.0-4.8 kWh for a standard vented or condenser dryer, cutting running costs by more than half over the machine’s lifetime.
Does a vented or condenser dryer cost more to run?
They’re close – a condenser dryer usually uses slightly more energy per cycle (typically 4.2-4.8 kWh vs 4.0-4.5 kWh for vented) because it needs extra energy to condense moisture out of the air rather than vent it outside.
How can I make my tumble dryer cheaper to run without buying a new one?
Spin your washing at the highest safe speed first to remove more water mechanically, clean the lint filter every single cycle, avoid overloading or under-loading the drum, and use an auto/sensor-dry cycle instead of a fixed timer so it stops as soon as clothes are dry.
How much electricity does a tumble dryer use per year?
For an average household running a standard vented or condenser dryer 4 times a week, expect roughly 850-1,000 kWh per year – about £210-£245 at UK rates or $145-$170 at US rates. A heat pump dryer used the same amount uses only around 350-400 kWh/year.
Is it cheaper to air-dry clothes than use a tumble dryer?
Air-drying (on a line or airer) costs essentially nothing in electricity, so it’s always cheaper than a tumble dryer when weather and space allow – the trade-off is time and, for line-drying, weather dependency.
Does dryer size affect running cost?
Yes – larger-drum dryers (9-10kg+) use more energy per cycle than smaller ones (6-7kg) at full load, but they can be more cost-efficient per garment if you’re doing fewer, larger loads instead of more frequent small ones.
