Tumble Dryer Running Cost Calculator UK
Find out exactly how much your tumble dryer costs to run with our free UK calculator. Select your dryer type — vented, condenser or heat pump — enter your cycle duration and weekly loads, and see costs per load, weekly, monthly and annually. The calculator uses the current Ofgem electricity rate of 24.5p per kWh so your results reflect real-world prices.
Tumble dryers are one of the most expensive household appliances to run, with a standard vented dryer costing around £1.23 per cycle. Over a year, that can add up to £190 or more. However, the type of dryer you use makes a huge difference. A heat pump dryer uses roughly 60% less energy per cycle than a vented model, potentially saving over £100 per year. Use this calculator to compare the running costs of different dryer types and see whether upgrading could pay for itself through lower electricity bills.
Vented, Condenser and Heat Pump Dryers Compared
The three main types of tumble dryer differ significantly in energy consumption and running cost. Vented dryers are the cheapest to buy but the most expensive to run, using around 5 kWh per cycle. Condenser dryers are slightly more efficient at 4.5 kWh per cycle and do not need an external vent hose, making them more flexible for placement. Heat pump dryers recycle hot air and use just 1.5 to 2 kWh per cycle, making them the most economical choice over time despite a higher purchase price.
The EU energy label, which the UK continues to use post-Brexit, rates dryers from A+++ to D. Most heat pump models achieve A++ or A+++, while vented dryers typically score C. Over a 10-year lifespan, the energy savings of a heat pump dryer can exceed £1,000 compared to a vented model. For the latest guidance on energy efficiency labels, see the Ofgem consumer advice page.
Money-Saving Alternatives to Tumble Drying
Air drying on an outdoor washing line is completely free and leaves clothes smelling fresh. When outdoor drying is not practical, a heated clothes airer uses around 300W and costs roughly 7p per hour, significantly less than any tumble dryer. A dehumidifier paired with an indoor clothes horse is another effective option, drawing 200 to 500W and speeding up drying times in cold or damp weather.
If you rely on your tumble dryer regularly, consider running it on an Economy 7 or smart tariff overnight when rates can be 50 to 70 percent lower.

Is It Worth Upgrading Your Tumble Dryer?
If you currently use a vented or condenser dryer and run three or more loads per week, upgrading to a heat pump model can save £80 to £120 per year on electricity. With heat pump dryers now available from around £400, the upgrade can pay for itself within three to four years. The savings are even greater for larger households running five or more loads per week.
Yes, considerably. A heat pump dryer uses roughly 2 kWh per cycle versus 4.5 kWh for a condenser. With 3 loads per week, that saves around £115 per year. The higher purchase price is typically recouped within 2–3 years.
An A+++ heat pump dryer uses less than half the electricity of a C-rated vented model. Over a 10-year lifespan, the difference can amount to over £1,000 in electricity savings.
Outdoor drying is free. A heated airer uses around 300W (about 7p per hour). A dehumidifier with an indoor clothes horse costs around 5–10p per hour and works well in cooler months.
Only on a time-of-use tariff such as Economy 7 with cheaper off-peak rates. On a standard single-rate tariff, electricity costs the same day and night.
Based on 3 loads per week: vented around £191, condenser around £172, heat pump around £76 per year. Use the calculator above for a personalised estimate.
