How much does it cost to run a washing machine?
How much it costs to run a washing machine depends mainly on the electricity used by the cycle and your current tariff. Using 0.47 kWh as a practical example, one wash costs [wb_cost kwh=”0.47″]. At five washes a week, the same routine costs [wb_cost kwh=”2.35″] weekly and [wb_cost kwh=”122.2″] yearly.
A washing machine does not have one fixed running cost. Programme, temperature, load, efficiency and your electricity tariff all matter. For the wider topic, see Washing Machine Running Costs.
Definition: Washing machine running cost is the electricity cost of completing a wash cycle. Work it out by multiplying the cycle’s electricity use in kWh by the unit rate you pay. On this site, the live electricity rate is shown as [wb_rate], so the money figure updates automatically.
How much does it cost to run a washing machine?
A useful starting point is the energy used by one cycle. If a wash uses 0.47 kWh, its electricity cost is [wb_cost kwh=”0.47″]. Your actual figure may be lower or higher depending on the programme and appliance.
UK energy labels show consumption over 100 Eco 40-60 washes. Divide that figure by 100 for a per-cycle estimate.

What affects the cost of one washing machine cycle?
The biggest influence is usually how much electricity the programme needs, especially for heating water. A hotter or more intensive wash can use more energy than an eco or cooler cycle, while actual consumption also changes with the load and machine design.
Programme and temperature
Energy Saving Trust advice recommends colder washes where suitable and using an eco cycle for ordinary dirty laundry. Eco programmes often take longer, but they are designed to reduce energy and water use rather than finish as quickly as possible.
If you regularly choose between common temperatures, 30 vs 40 wash cost is the more useful comparison than judging a programme by duration alone.
Load size and washing habits
Frequent small loads increase the number of cycles you pay for. A sensible full load, without overfilling the drum, usually makes better use of each wash. A half load does not necessarily cost exactly half because consumption varies by programme.
Energy efficiency
The current energy label gives a consistent way to compare machines. For washing machines, it includes an A-to-G efficiency class and electricity consumption for 100 Eco 40-60 cycles, making it easier to estimate a per-wash kWh figure before purchase.
How much does a washing machine cost per year in the UK?
Annual cost depends on two numbers: electricity used per cycle and how often you wash. At 0.47 kWh per cycle and five washes a week, yearly electricity use is 122.2 kWh, which costs [wb_cost kwh=”122.2″].
The arithmetic is 0.47 kWh multiplied by five washes, giving 2.35 kWh a week; over 52 weeks that becomes 122.2 kWh. Replace five with your own weekly figure.
For a personalised estimate, a washing machine running cost calculator is more useful than relying on a national average because it can reflect your own cycle use and frequency.
Is it cheaper to run a washing machine at night?
Only if your tariff charges less for electricity at certain times. On a standard single-rate tariff, moving the same wash from daytime to night does not normally change its unit cost.
If you have an Economy 7 or time-of-use tariff, check your supplier’s off-peak window. The cheapest period is set by the tariff, not simply by whether it is night.
When is cutting washing machine running cost not worth the effort?
Small savings are not worth turning every wash into a complicated optimisation exercise. If your machine already uses an efficient eco programme, you wash sensible loads and your weekly cycle count is modest, the remaining saving from constantly changing start times or micromanaging settings may be tiny. The same applies if your tariff has one electricity rate all day: running the machine at night will not magically make each kWh cheaper. Do not compromise cleaning results either.
Heavily soiled items, bedding or anything that needs a particular care temperature should be washed according to the fabric and appliance guidance. The most worthwhile changes are usually simple ones you can repeat: avoid unnecessary cycles, use cooler settings when suitable, fill the drum sensibly and choose eco where it meets the job. If those habits are already in place, focus on the total household bill rather than chasing fractions of a cycle. For more practical options, see reduce washing machine running costs.
Frequently asked questions
How do I use the energy label to estimate cost per wash?
Find the kWh figure for 100 Eco 40-60 cycles and divide it by 100. Multiply the result by your electricity unit rate to estimate one wash.
Does a quick wash always use less electricity?
No. Programmes balance time, temperature, water and drum action differently, so a shorter cycle is not automatically the lowest-energy choice. Check your machine’s programme information.
Does a half load cost half as much as a full load?
Usually not. Some machines adjust consumption for smaller loads, but they still use energy for pumping, spinning and other parts of the cycle.
Should I include the standing charge in the cost of one wash?
Normally, no. The standing charge applies to the electricity supply rather than one washing-machine cycle, so per-wash comparisons are clearer using the unit rate only.
Can using an eco cycle reduce washing machine electricity use?
Yes, when it suits the load. Energy Saving Trust recommends eco cycles for dirty laundry because they are designed to use less energy even though they can take longer.
The simplest way to estimate a washing machine’s running cost is to start with kWh per cycle, multiply by how often you wash and let the current electricity rate convert that energy into money. Once you know those numbers, you can see whether changing temperature, programme or washing frequency will make a meaningful difference.
