How Much Electric
Does a Tumble Dryer Use?
Tumble dryers vary enormously in running cost. A vented dryer pulls 2 to 3 kWh per cycle. A heat pump dryer uses half that. At the current 24.7p Ofgem rate that means £0.50 to £1.20 per cycle plus a meaningful annual gap between technology types.
A typical UK tumble dryer uses 2 to 5 kWh of electricity per drying cycle depending on type plus load size. At the current Q2 2026 Ofgem unit rate of 24.7p per kWh that means: vented dryer 2 to 3 kWh per cycle (49p to 74p), condenser dryer 3 to 4 kWh per cycle (74p to 99p) plus heat pump dryer 1.2 to 2 kWh per cycle (30p to 49p). For a typical household running 3 to 4 cycles per week, annual costs range from £47 for a heat pump dryer to £155 for a condenser model.
The figures that matter
Heat pump
Most efficient type. Cycle costs 30p to 49p at current Ofgem rate.
Vented
Older technology, requires external vent. Cycle costs 49p to 74p.
Condenser
No external vent needed. Cycle costs 74p to 99p, the most expensive type.
Annual cost
Range across types at 3 to 4 cycles weekly for a typical UK family.
Four things to consider
Heat pump wins long term
Heat pump dryers use roughly half the electricity of vented or condenser models per cycle.
Load size matters
Half-empty cycles waste electricity. Full but not over-stuffed loads hit peak efficiency.
Filters block performance
Lint-clogged filters force the dryer to run longer plus harder. Clean every cycle.
Air drying is free
Line drying or rack drying costs nothing. Useful through UK summer plus mild months.
Vented vs condenser vs heat pump dryers compared
Tumble dryer running costs vary by 2 to 3 times across the technology types. The headline numbers do not change much by brand within a type so the choice is mostly about which technology fits the home plus the household budget.
Real numbers at 24.7p per kWh (Q2 2026 Ofgem cap):
- Vented dryer (2 to 3 kWh per cycle). 49p to 74p per cycle. £76 to £115 per year at 3 weekly cycles. Requires external vent through wall or window.
- Condenser dryer (3 to 4 kWh per cycle). 74p to 99p per cycle. £115 to £155 per year. No external vent needed but slightly higher running cost.
- Heat pump dryer (1.2 to 2 kWh per cycle). 30p to 49p per cycle. £47 to £76 per year. Uses heat exchanger technology to recycle warm air. Cheapest to run.
Why heat pump dryers are cheaper to run. Conventional dryers heat fresh air, push it through the drum then exhaust it (vented) or condense the moisture out then heat fresh air again (condenser). Heat pump dryers use a closed circuit. The same warm air is dehumidified, reheated plus pushed through the drum repeatedly. Less energy is needed because heat is recycled rather than constantly replaced.
The heat pump trade-off. Heat pump dryers cost 50 to 100 percent more to buy (£500 to £900 versus £250 to £450 for condenser). Cycles take 2 to 3 hours instead of 1 to 1.5 hours. The payback period at typical UK use plus current electricity rates is usually 2 to 4 years depending on cycle frequency. For households running 4+ cycles per week, heat pump is clearly cheaper long term.
What pushes any dryer cost higher:
- Lint-clogged filters. Reduce airflow, force longer cycles, sometimes 30 percent more energy per load.
- Wet wash going in. Spinning at higher speed in the washing machine first reduces dryer cycle length plus cost significantly.
- Wrong cycle setting. Cottons cycle on synthetics is wasteful plus vice versa.
- Old filter foam plus heat exchanger fouling on heat pump dryers. Annual deep clean restores efficiency.
Real number ranges
Cost per drying cycle (UK 2026, 8kg load)
Inside a typical 90-minute drying cycle
Heater on full
Element pulls full power to bring drum air up to 60°C. Highest draw of the cycle.
Steady drying
Cycling on plus off to maintain heat. Average draw 1.5 to 2.5kW depending on dryer type.
Cool-down
Heater off. Drum continues turning to cool clothes plus prevent creasing. Low draw 100 to 200W.
End of cycle
Anti-crease tumble plus alarm. Total energy use depends on dryer type plus load size.
Four ways to cut tumble dryer running costs
Spin at 1400rpm or higher
Higher washing machine spin speed extracts more water before drying starts. Cuts dryer cycle by 15 to 25 percent.
Clean the lint filter every cycle
Five seconds of work. Restores airflow plus cuts energy use by up to 30 percent on dirty filters.
Match cycle to fabric
Synthetics cycle for synthetics. Cotton cycle for cotton. Wrong cycle wastes energy plus risks shrinkage.
Choose heat pump on next replacement
Higher upfront cost but pays back in 2 to 4 years through lower running costs plus saves £50 to £100 per year ongoing.
Compare the options
Heat pump dryer
- ✓1.2 to 2 kWh per cycle typical for an 8kg load.
- ✓30p to 49p per cycle at 24.7p per kWh.
- ✓£47 to £76 per year at 3 weekly cycles.
- ✓Closed-loop heat recycling. Far more efficient over the cycle.
- ✓No external vent needed. Suits flats plus modern homes.
Condenser or vented dryer
- ✗2 to 4 kWh per cycle for vented or condenser.
- ✗49p to 99p per cycle at the same Ofgem rate.
- ✗£76 to £155 per year at the same 3 weekly cycles.
- ✗Heated fresh air dumped after each cycle. Energy waste built into the design.
- ✗Vented type needs external vent. Condenser type needs water tank emptying.
