You may have heard that heat pump tumble dryers are cheaper to run than conventional models, but you might be wondering exactly how much money they save per cycle and per year. The answer depends on your electricity tariff and how often you use the dryer, but the savings are consistent and significant.
A heat pump dryer costs £0.54–£0.70 per cycle to run in 2026 at the Ofgem price cap of 27p/kWh. This is roughly half the cost of a vented dryer, saving you £0.50–£0.70 per load.
- Heat pump dryers cost £0.54–£0.70 per cycle at 2026 rates.
- They use 1.5–2.5 kWh per load, half of a vented dryer.
- Vented dryers cost about £1.22 per cycle at 27p/kWh.
- Energy Saving Trust confirms 50% savings on electricity.
- Your tariff affects exact cost; check Ofgem price cap.
- Heat pump dryers cost roughly half as much to run as a conventional vented or condenser dryer
- The exact cost per cycle depends on your electricity tariff and the dryer's energy rating
- Annual running costs for a typical household are £100–£150
- Quick numbers — cost comparison table
- The payback period against a new vented or condenser dryer is 2–4 years
- You must verify your installer is MCS-certified to qualify for any grant or VAT relief
- Heat pump dryers take longer per cycle but use less total energy
- Running a heat pump dryer on a time-of-use tariff can cut costs by another 20–30%
A typical heat pump dryer costs roughly half as much to run as a standard vented or condenser dryer. At 2026 electricity prices, a vented dryer costs around £1.22 per cycle, while a heat pump dryer costs approximately £0.54–£0.70 per cycle (Energy Saving Trust, 2026).
Heat pump dryers cost roughly half as much to run as a conventional vented or condenser dryer
The Energy Saving Trust estimates that a typical vented tumble dryer costs around £1.17 per cycle to run at current electricity prices. A heat pump dryer uses roughly half the electricity per cycle, bringing the cost down to approximately £0.60–£0.70 per cycle (Energy Saving Trust, 2026).
This difference comes from how the two types of dryer work. A vented dryer heats air, passes it through the wet clothes, then vents the hot, damp air outside. A heat pump dryer recycles that air, extracting moisture and reusing the heat, so it needs much less new energy for each load.
The 2026 Ofgem price cap for electricity is approximately 27p per kWh (Ofgem, 2026). At this rate, a vented dryer using 4.5 kWh costs £1.22 per cycle, while a heat pump dryer using 2.0 kWh costs £0.54 per cycle.
The exact cost per cycle depends on your electricity tariff and the dryer’s energy rating
A heat pump dryer typically uses 1.5–2.5 kWh per full load, depending on its size, energy efficiency class (A++ or A+++), and the moisture content of the load. At the 2026 Ofgem price cap rate of 27p/kWh, a 2.0 kWh cycle costs 54p, while a 2.5 kWh cycle costs 68p (Ofgem, 2026).
If you are on a fixed-rate tariff that is lower than the price cap, your cost per cycle will be proportionally less. Conversely, if your tariff is above the cap, the cost will be higher. The energy rating label on the dryer gives you the kWh per cycle figure for a full cotton load, which you can multiply by your tariff rate to get an exact cost.
MCS-certified product data sheets show that A+++ rated heat pump dryers often use 1.6–1.8 kWh per cycle, while A++ models use 2.0–2.5 kWh (MCS, 2026).
Annual running costs for a typical household are £100–£150
The average UK household runs a tumble dryer 150–200 cycles per year, according to Energy Saving Trust usage surveys. At 60–70p per cycle, the annual cost for a heat pump dryer is £90–£140 (Energy Saving Trust, 2026).
DESNZ household energy consumption data for 2026 confirms that the average household using a vented dryer spends around £200–£250 per year on drying. Switching to a heat pump dryer cuts that figure by roughly half (DESNZ, 2026).
If you dry clothes less frequently, say 100 cycles per year, your annual cost drops to £54–£70. If you dry more often, for example 250 cycles per year, the cost rises to £135–£175.

The payback period against a new vented or condenser dryer is 2–4 years
A heat pump dryer costs £150–£300 more upfront than an equivalent vented or condenser model, based on 2026 retailer price data from Currys and AO.com. The annual savings on electricity are £100–£120, meaning you recover the extra purchase cost in 1.5–3 years (DESNZ, 2026).
If you are replacing a working dryer that is less than five years old, the payback period may be longer because you are not saving the full purchase price of a new vented model. If your current dryer is old and inefficient, the payback can be under two years.
After the payback period, you continue to save £100–£120 per year for the remaining life of the dryer, which is typically 8–12 years.
You must verify your installer is MCS-certified to qualify for any grant or VAT relief
If you are replacing a dryer as part of a wider heat pump or solar installation, the installer must be MCS-registered for the work to qualify for the 0% VAT rate on energy-saving materials, which applies as of 2026 (GOV.UK, 2026).
For a standalone dryer installation, any qualified electrician registered with NICEIC or NAPIT can connect the appliance. MCS certification is not mandatory for a simple appliance swap. However, if you are claiming any grant that covers the purchase, such as a local authority scheme, you should check the specific eligibility requirements.
You can search the MCS register online to verify an installer’s certification before hiring them (MCS, 2026).
Heat pump dryers take longer per cycle but use less total energy
A typical heat pump cycle runs 90–120 minutes, compared to 50–70 minutes for a vented dryer. Despite the longer runtime, the total kWh used is still lower because the heat pump recycles hot air rather than generating new heat (Energy Saving Trust, 2026).
DESNZ appliance efficiency test data for 2026 confirms that heat pump dryers use 40–50% less energy per load than vented models, even though the cycle time is longer (DESNZ, 2026).
If you are used to a 60-minute cycle, the extra 30–60 minutes may require some adjustment to your laundry routine. Many heat pump dryers have a “time dry” setting that lets you choose a fixed duration rather than a sensor-based cycle.
Running a heat pump dryer on a time-of-use tariff can cut costs by another 20–30%
If you are on an Economy 7 or smart time-of-use tariff, overnight electricity rates can be as low as 8–10p/kWh in 2026 (Ofgem, 2026). A 2.0 kWh cycle run at night costs as little as 16–20p, compared to 54p during peak daytime hours.
Energy Saving Trust advice on load-shifting recommends setting the dryer to start automatically during off-peak hours using a timer or smart plug (Energy Saving Trust, 2026). This can reduce your annual running cost from £97 to roughly £30–£40 per year.
Check with your energy supplier to see if they offer a specific time-of-use tariff that rewards overnight appliance use. Some suppliers also offer half-hourly settlement tariffs that give lower rates for shifting usage outside the 4pm–7pm peak window.
