How Much Electric
Does a Washing Machine Use?
A washing machine cycle costs anywhere from 6p on a cold wash to 50p on a 60°C boil wash at 2026 UK rates. The single biggest variable is the wash temperature, accounting for around 90 percent of cycle electricity use.
A typical UK washing machine uses 0.25 to 2 kWh per cycle depending on temperature plus load size. At the current Q2 2026 Ofgem unit rate of 24.7p per kWh, a 30°C cold-ish wash costs 6p to 12p per cycle, a 40°C wash costs 15p to 25p plus a 60°C wash costs 30p to 50p. For typical UK households running 4 to 5 cycles per week, annual cost ranges from £12 to £130 depending on temperature choices. Heating water is 90 percent of the cycle energy use.
The figures that matter
Cold or 30°C wash
Modern detergents work well at low temperatures. Cheapest cycle option.
40°C standard
Most common UK wash temperature. Balance of cleaning power plus efficiency.
60°C wash
Hot wash for whites, towels, bedding plus heavily soiled loads.
Heating share
Heating water dominates cycle energy use. Pumps plus motor are minor contributors.
Four things to consider
Temperature drives cost
Each step up from 30°C to 40°C to 60°C roughly doubles the cycle electricity use.
Modern detergents work cold
Cold or 30°C cycles clean well with current biological detergents. No need to wash everything hot.
Half loads waste energy
A half-full machine uses similar electricity to a full one. Wait until full before running.
Eco mode is a real saving
Eco programmes use lower temperature plus longer wash time. 30 to 40 percent saving versus standard.
Where washing machine electricity actually goes
A washing machine uses electricity for two main things: heating water (around 90 percent of cycle energy) plus running the motor and pumps (the remaining 10 percent). The wash temperature you choose directly controls roughly 90 percent of the cycle's running cost.
Real numbers at 24.7p per kWh (Q2 2026 Ofgem cap):
- Cold or 20°C wash. 0.2 to 0.4 kWh per cycle. 5p to 10p per cycle. £11 to £21 per year at 4 weekly cycles.
- 30°C wash. 0.3 to 0.5 kWh per cycle. 7p to 12p per cycle. £16 to £26 per year.
- 40°C wash. 0.6 to 1 kWh per cycle. 15p to 25p per cycle. £31 to £52 per year.
- 60°C wash. 1.2 to 2 kWh per cycle. 30p to 49p per cycle. £63 to £103 per year.
- 90°C wash (rarely used). 2 to 2.8 kWh per cycle. 49p to 69p per cycle. £103 to £144 per year.
Why low temperature wins on running cost. Heating water from cold to 60°C requires roughly 4 times more energy than heating to 30°C. For most everyday loads, modern biological detergents work effectively at 30°C or even cold cycles. The exceptions are bedding, towels plus heavily soiled work clothes which benefit from 40 to 60°C for hygiene reasons.
What changes the cost most:
- Wash temperature. Single biggest factor as detailed above.
- Spin speed. Higher spin extracts more water, reducing dryer cycle time afterwards. Worth pairing.
- Load size. Half-full machines waste roughly half the energy per item washed.
- Eco programme. Uses lower water temperature plus longer wash time. 30 to 40 percent cheaper than standard.
- Machine age. Pre-2015 machines often use 30 to 50 percent more per cycle than current A-rated models.
Spin speed plus dryer interaction. Washing at 1400rpm extracts much more water than 800rpm. Higher spin uses negligible extra electricity (the motor runs the same time but faster) but cuts dryer cycle time by 15 to 25 percent. Pair high spin with the dryer cycle for the best total laundry cost.
Real number ranges
Cost per washing machine cycle (UK 2026, 8kg load)
Inside a typical 90-minute 40°C cycle
Fill plus pre-wash
Cold water in. Drum agitates briefly. Pumps run at low draw. Energy use minimal.
Heat plus wash
Element heats water to 40°C. Heating element pulls 1.8 to 2.2 kW briefly. 0.5 to 0.8 kWh accumulated.
Wash plus rinses
Drum tumbles. Rinses with cold water (no heating). Element idle. Motor at low draw.
Spin plus drain
Drum spins at 1400rpm to extract water. Motor at peak briefly. Final cycle 0.6 to 1 kWh total.
Four ways to cut washing machine running costs
Wash at 30°C by default
Modern detergents handle most everyday loads at 30°C. Saves 50 to 70 percent versus 40°C cycles.
Always run a full load
Half loads waste roughly half the energy per item washed. Wait until the drum is full but not over-stuffed.
Use the eco programme
Eco cycles wash longer at lower temperature. 30 to 40 percent cheaper than standard equivalent.
Spin at 1400rpm or higher
Higher spin extracts more water, cuts dryer cycle time afterwards. Negligible extra washing cost.
Compare the options
30°C eco wash
- ✓0.3 to 0.5 kWh per cycle for 8kg load.
- ✓7p to 12p per cycle at 24.7p per kWh.
- ✓£16 to £26 per year at 4 weekly cycles.
- ✓Modern detergents work fine on most everyday loads.
- ✓Lower wear on garments. Colours plus elastic last longer.
60°C standard wash
- ✗1.2 to 2 kWh per cycle for the same load.
- ✗30p to 49p per cycle at the same Ofgem rate.
- ✗£63 to £103 per year at the same 4 weekly cycles.
- ✗Only needed for towels, bedding plus heavily soiled loads.
- ✗More wear on garments. Hot washes shorten clothing lifespan.
