How much does it cost to run a heat pump tumble dryer in the UK?

Price updated 9 July 2026 · Q3 2026 (Jul–Sep)

A typical heat pump tumble dryer (900 W) used 1.5 hours a day, 4 days a week costs about £6.13 a month (£73.52 a year) at 26.11p/kWh.

A heat pump tumble dryer recycles warm air instead of constantly heating fresh air and venting it, so it draws far less power — typically 600–1,200W against 2,000–3,000W for a conventional dryer. Cycles run longer (heat pump dryers work at lower temperatures) but use roughly a third of the electricity per load. Over a year of regular drying the running-cost saving usually outweighs the higher purchase price, which is the main reason to choose one.

Cost by model power

The same heat pump tumble dryer can vary a lot between models, so here is the range from a low-power to a high-power example.

Based on 1.5 hours a day, 4 days a week, at 26.11p/kWh.
ModelPowerPer hourPer dayPer monthPer year
Low-power model 600 W 16p 23p £4.08 £49.01

High-power model 1,200 W 31p 47p £8.17 £98.02
How we model this: Cycles are longer but at much lower power. The wattage shown reflects the lower running power of the heat pump system.

What changes the cost

  • Much lower power than a vented dryer
  • Longer cycle times at lower temperature
  • Spin speed of the wash beforehand
  • Load size
Save money: The longer cycle time can look alarming, but the low wattage means a full load still costs far less than a conventional dryer — run full loads to make the most of it.

Common questions

Is a heat pump dryer really cheaper to run?

Yes — it uses around a third of the electricity of a conventional dryer per load, because it recycles warm air rather than heating and venting it.
