Heated airers have quietly become one of the most popular winter energy-saving buys in the UK, and for good reason. When drying a single load in a condenser tumble dryer can cost well over a pound, a device that dries the same washing for pennies is an easy sell. But how much does a heated airer actually cost to run, and is it really cheaper than the alternatives? This guide gives you the real 2026 numbers.

The short version is that a typical heated airer costs roughly 7p to 8p an hour to run, which works out at around 20p to 45p per load of washing depending on how you use it. That makes it three to five times cheaper than a standard tumble dryer for the same job. Below we show exactly how those figures are calculated so you can work out your own cost.

How much does a heated airer cost to run per hour?

The running cost of any electrical appliance comes down to one simple sum: its power rating in kilowatts, multiplied by the number of hours you run it, multiplied by your electricity unit rate.

Most heated clothes airers on the UK market draw between 230 and 300 watts. That is far less than people assume - a 300W airer uses less electricity than a single old-fashioned incandescent light bulb used to, and roughly the same as running a laptop and a couple of phone chargers. We will use 300W (0.3kW) as our worked example because that is what the popular tiered heated airers pull, and an electricity unit rate of 24.5p per kWh, in line with the current price cap and the figure we use across our other cost guides.

So a heated airer costs about 7p to 8p for every hour it runs. A smaller 230W model costs closer to 5.6p an hour, and a larger 1000W heated towel-rail style airer would cost about 24.5p an hour - always check the wattage on the box or the plate on the plug before you buy.

If you want to know the exact draw of your own airer rather than trusting the label, a cheap plug-in energy monitor sits between the plug and the socket and tells you precisely how many kWh it uses over a real drying session. It is the single best way to turn the estimates in this guide into your own hard numbers.

Cost per load of washing

Hourly cost only matters once you know how long a load actually takes to dry. On its own, an open heated airer will dry a full load of washing in roughly six to eight hours, which puts a load at around 44p to 59p. The trick that transforms the economics is a cover.

A heated airer cover - essentially a lightweight tent that zips over the frame - traps the warm air around the clothes instead of letting it drift into the room. That typically halves the drying time to around three to four hours, so a covered load drops to roughly 22p to 30p. Many heated airers now come with a cover included; if yours did not, it is the cheapest upgrade you can make and it usually pays for itself within a few weeks.

Here is a realistic per-load picture depending on how you run it.

Those figures assume a normal mixed load. Thick towels and jeans take longer than shirts and underwear, so heavy loads sit at the top of each range.

Heated airer vs tumble dryer: the real comparison

This is the comparison most people are actually looking for, and it is where the heated airer earns its keep. A tumble dryer does the same job far faster, but it draws vastly more power. The question is whether the speed is worth the cost.

The gap is stark. A covered heated airer at around 22p a load is roughly a quarter of the cost of a condenser dryer at £1.37, and comfortably cheaper than a vented model too. Over a year of regular washing - say five loads a week - that is the difference between spending about £57 a year on a heated airer and close to £356 on a condenser tumble dryer. The airer saves you around £300 a year.

The one appliance that competes on cost is a modern heat pump tumble dryer, which sips electricity and can match a heated airer per load while drying in a fraction of the time. But a heat pump dryer costs £400 to £700 to buy, whereas a heated airer costs £30 to £180, so the airer wins decisively on upfront price. If you already own a heat pump dryer the running costs are close; if you are choosing what to buy, the airer is the low-risk, low-cost option.

Is a heated airer cheaper than central heating?

A common mistake is to dry clothes by cranking up the radiators or draping washing over them. Running your gas central heating harder, or worse using a plug-in electric heater to dry a room, costs far more than a 300W airer. A 2kW electric heater costs around 49p an hour to run - more than six times a heated airer - and it heats the whole room rather than the clothes.

Drying clothes on radiators also pushes a lot of moisture into the air, which can lead to condensation and damp on cold walls and windows. A heated airer with a cover keeps that moisture contained, and pairing it with a dehumidifier pulls the water straight out of the air. A small dehumidifier draws only about 200W, so the combination still comes in well under the cost of heating the room, while protecting your home from damp. If winter condensation is a problem in your home, our guide to draught proofing covers the other cheap fixes that keep rooms warmer and drier.

The best heated airers in the UK for 2026

There is no single best heated airer - the right one depends on how much washing you do and where you will put it. Here is how the main types compare.

For most households a 3-tier heated airer hits the sweet spot: it holds a full load, folds flat for storage, and usually comes with a cover that keeps the running cost down. If you only wash for one or two people, a smaller winged heated clothes airer is cheaper to buy and to run, and takes up far less space.

Whichever you pick, the two things that matter most for running cost are the wattage - lower is cheaper - and whether it comes with a cover. Do not pay a premium for high wattage thinking it dries faster; a covered 300W airer will out-dry an uncovered 600W one while using half the power.

How to cut your heated airer running costs further

A few simple habits shave real money off the numbers above.

Always use a cover. This is the single biggest lever. Halving the drying time halves the cost, every single load. If your airer did not come with one, buy one.

Spin your washing on a high setting first. A fast spin cycle in the washing machine removes far more water than a slow one, so clothes arrive at the airer damper rather than soaking. Less water to evaporate means less time running.

Space clothes out and turn them once. Overloading the airer traps damp fabric against damp fabric. Give each item a little air and flip the thickest pieces halfway through.

Dry in the warmest, best-ventilated room you can. A cold, sealed room slows evaporation. A slightly warmer room with a cracked window or a dehumidifier running clears the moisture faster.

Only run it as long as it needs. Many airers have no timer, so it is easy to leave one running all day out of habit. A cheap plug-in timer switch turns it off automatically once the load is dry.

If you have a smart meter, watch your in-home display for the hour or two after you switch the airer on. Seeing the tiny bump in usage first-hand is reassuring, and it is the same visibility effect we describe in our guide to whether smart meters save you money - once you can see how little it costs, you stop worrying about it. To model where the rest of your electricity pounds are going, our smart meter savings calculator is a good place to start.

Frequently asked questions

Are heated airers expensive to run? No. A typical heated airer costs about 7p to 8p an hour, or roughly 20p to 45p per load of washing depending on whether you use a cover. That is far cheaper than a standard tumble dryer and a fraction of the cost of drying clothes with an electric heater.

How much does a heated airer cost to run for 8 hours? A 300W heated airer run for a full 8 hours uses 2.4 kWh, which costs about 59p at an electricity rate of 24.5p per kWh. In practice, using a cover means most loads dry in three to four hours for around 22p to 30p, so you rarely need the full eight hours.

Is a heated airer cheaper than a tumble dryer? Yes, for every type except a heat pump tumble dryer. A covered heated airer costs around 22p a load versus roughly 92p for a vented dryer and £1.37 for a condenser dryer. A modern heat pump dryer is the only one that competes on running cost, but it costs several hundred pounds more to buy.

Do heated airers cause damp or condensation? They can push moisture into the air like any indoor drying, but far less than draping washing on radiators. Using the cover contains most of the moisture, and running a small dehumidifier alongside removes it entirely while still costing less than heating the room.

How long does a heated airer take to dry clothes? Around six to eight hours uncovered, or three to four hours with a cover fitted. A good spin cycle beforehand and spacing the clothes out both speed things up.

The bottom line

A heated airer is one of the cheapest ways to dry washing indoors in the UK. At about 7p to 8p an hour, and roughly 22p a load with a cover, it undercuts every tumble dryer except a heat pump model and costs a tiny fraction of drying clothes on radiators or with an electric heater. Buy one with a cover, spin your washing hard before it goes on, and you can dry your laundry all winter for the price of a few coffees a month. For most UK households, it is one of the easiest energy-saving wins going.
