The average UK tumble dryer costs between £0.60 and £1.50 per cycle to run, depending on the model type and energy tariff, according to Energy Saving Trust data (Energy Saving Trust, 2026). A vented or condenser dryer on a full load uses roughly 4.5 kWh per cycle, while a heat-pump model uses about 2.0 kWh.
The exact cost depends on your electricity tariff, which averages £0.30 per kWh in 2026, and the dryer’s energy rating. Older appliances often cost more per cycle, while modern heat-pump models can cut running costs by up to 50%. The cycle length and load size also affect the total, overfilling or underfilling increases energy use.
Vented and condenser dryers cost more per cycle
Vented and condenser tumble dryers are the most common types in UK homes. A typical vented dryer uses around 4.5 kWh per cycle, costing about £1.35 at the 2026 average tariff of £0.30/kWh (GOV.UK, 2026). Condenser models are similar, with a 4.0–4.5 kWh draw. These dryers heat air directly, then expel moisture, which is energy-intensive. Running a full load weekly adds roughly £70 to your annual electricity bill. Energy rating labels from A to G show consumption, an A-rated vented dryer uses about 4.0 kWh, while a D-rated model can exceed 5.0 kWh.
Heat-pump dryers cut running costs by half
Heat-pump tumble dryers recycle hot air, using around 2.0 kWh per cycle, roughly £0.60 at the 2026 tariff (Energy Saving Trust, 2026). This makes them the most efficient option, with annual costs of about £31 for weekly use. They are typically A+++ rated, and the higher upfront price (often £100–£200 more than vented models) is offset by lower running costs over 5–10 years. Heat-pump dryers also run at lower temperatures, which is gentler on fabrics. However, cycles take longer, often 90–120 minutes compared to 60 minutes for vented dryers, so time savings are not a benefit.
Tariff choice and load size affect your actual cost
Your electricity tariff directly determines the per-cycle cost. At the 2026 average of £0.30/kWh, a 4.5 kWh vented cycle costs £1.35, but if you are on a time-of-use tariff (e.g., Economy 7 at £0.18/kWh off-peak), the same cycle drops to £0.81 (Ofgem, 2026). Running the dryer during off-peak hours can save 40% or more. Load size matters too, a half-full drum reduces efficiency, as the dryer uses nearly the same energy for less drying. Always dry full loads but avoid overfilling, which extends cycle time. Using a sensor-dry setting (common on newer models) stops the cycle when clothes are dry, saving up to 20% energy versus timed drying.
A worked example
A typical UK household running a heat-pump tumble dryer once a week on the 2026 average electricity tariff of £0.30 per kWh spends about £31 per year, or roughly £0.60 per cycle. Take a 1930s semi-detached home in Manchester with a family of four. They upgrade from a 10-year-old vented dryer using 4.5 kWh per cycle to a modern A-rated heat-pump model using 2.0 kWh per cycle. At £0.30 per kWh, the old dryer costs £1.35 per cycle, while the new one costs £0.60, saving £0.75 each time. Over 52 cycles a year that is a £39 saving. The heat-pump dryer costs around £700 to buy, and with the 0% VAT reduction on energy-saving materials until March 2027, the upfront price drops to about £583. The payback period is roughly 15 years based on energy savings alone. The Energy Saving Trust confirms that heat-pump dryers use half the energy of vented or condenser models, making them the most cost-effective choice over the appliance’s 15- to 20-year lifespan.

What homeowners often get wrong
The most common mistake UK homeowners make is assuming all tumble dryers cost the same to run per cycle, leading to a £70 annual difference between a vented and a heat-pump model. Three key errors repeat across households.
- Buying a vented dryer for low upfront cost A vented dryer might cost £200 less than a heat-pump model, but it uses 4.5 kWh per cycle versus 2.0 kWh, adding £70 a year to bills. Over a 15-year lifespan, that is £1,050 wasted on electricity.
- Ignoring the energy rating label Many shoppers look only at price and capacity, not the A to G rating. An F-rated vented dryer uses over 5.0 kWh per cycle, costing £1.50 at £0.30 per kWh, which is more than double an A-rated heat-pump model at £0.60 per cycle.
- Overloading the drum to save time Stuffing a dryer full makes the motor work harder and extends drying time, increasing energy use by up to 30%. A half-full load also wastes energy because the dryer runs just as long. The right approach is a loosely packed drum with space for air to circulate.
Quick reference
- A heat-pump tumble dryer costs about £0.60 per cycle at £0.30 per kWh, while a vented model costs about £1.35 per cycle.
- Running a vented dryer once a week adds roughly £70 to your annual electricity bill, compared to £31 for a heat-pump model.
- All new tumble dryers sold in the UK must display an A to G energy label, with A-rated models using under 2.5 kWh per cycle.
- Heat-pump dryers have a payback period of 10 to 15 years against cheaper vented models, but their total lifetime cost is lower.
- Using a dryer on a half-load or overfilling the drum can increase energy use by 20–30%, so always follow the manufacturer’s load guidance.
Frequently Asked Questions
A tumble dryer costs roughly £0.60 to £1.35 per hour, depending on the model and tariff. The Energy Saving Trust states heat-pump models use about 2.0 kWh per cycle, while vented dryers use 4.5 kWh.
