Laundry is one of those household costs that hides in plain sight. The average UK family runs the washing machine four or five times a week, and if every load goes straight into the tumble dryer, the annual energy bill for clean clothes can easily top £250 before detergent costs even start. The good news is that laundry is also one of the easiest household jobs to run for less. A few changes to cycle settings, detergent habits and drying routines can cut the cost of every load without your clothes looking or smelling any worse. This guide walks through the laundry savings that actually work in the UK in 2026.
Know what each wash actually costs
Start with the maths. With electricity at roughly 27p per kWh under the current price cap, a typical 40 degree cotton wash costs around 20p in electricity. The same wash at 30 degrees drops to roughly 10-14p. A conventional vented or condenser tumble dryer, by contrast, can swallow 2-3 kWh per load, which works out at 60-80p a time. Multiply that by four or five loads a week and a family drying everything electrically can spend well over £200 a year on drying alone. Our energy bill calculator lets you plug in your own appliance ratings and tariff to see exactly where your money goes.
Drop to 30 degrees
Modern detergents are formulated to clean brilliantly at low temperatures, yet many households still default to 40 or even 60 degrees. Washing at 30 degrees typically uses around a third less energy than a 40 degree cycle, and a 20 degree cycle saves even more. For lightly worn everyday clothes, low temperatures are all you need. A few sensible exceptions:
- Towels, bedding and anything germy benefit from a 60 degree wash now and then, especially when someone in the house has been ill.
- Badly stained or greasy items may need a warmer wash or a pre-soak rather than making every load hotter.
- Sportswear and technical fabrics clean better at 30 degrees or below – heat can trap odours in synthetic fibres.
Worried about a gunky machine from constant cold washes? Run an occasional empty hot service wash with soda crystals – one hot cycle a month costs far less than making every wash hot.
Wait for a full load
A washing machine uses nearly the same amount of energy and water whether it is half full or completely full, so half loads are pure waste. A household that runs seven half-full washes a week can cut to four full ones and save around £40 a year in electricity and water heating without washing anything less often. The caveat is the other extreme: cramming the drum so full that clothes cannot tumble reduces cleaning power and forces you to rewash. Fill the drum about three quarters full, and sort loads by fabric weight as well as colour so that heavy items are not dragging the cycle length up for everything else.
Learn the detergent maths
Detergent is where supermarkets quietly make their biggest margins, and where shoppers quietly lose the most money. The tricks are simple once you know them:
- Compare price per wash, not price per pack. Big brands can work out at 15-20p per wash, while good own-brand powders and liquids from Aldi and Home Bargains can come in at 4-8p. Our price per unit calculator does the maths for you on the shelf.
- Never pay full price for branded detergent. Ariel, Persil and Fairy are on a half-price offer somewhere almost every week of the year – check the Tesco, Sainsbury’s and Asda deal pages and stock up when the price halves.
- Measure properly. Most people pour in more than the dosing ball suggests, but extra detergent does not clean better – it rinses money down the drain and can leave clothes stiff.
- Do not buy every special product. Separate stain removers, colour catchers, scent boosters and in-wash fragrance beads are mostly optional. A good detergent, correct dosing and prompt stain treatment with a bar of soap covers almost everything.
A family switching from full-price branded detergent to well-timed offers, correct dosing and own-brand basics can save £60-100 a year without noticing any difference in the wash basket.
Skip the extras you do not need
Fabric conditioner is the classic optional product sold as essential. It is genuinely useful for stiff towels or hard water areas, but many households can halve the dose or skip it entirely – and if you line dry or use an airer, you do not need dryer sheets at all. If you do use conditioner, buy it on offer like everything else.
Cut the cost of drying
Drying is the big one. It is the single most expensive thing most households do to their clothes, and the place where the savings are largest:
- Line dry whenever the weather allows. It is free, and daylight helps fade stains and odours naturally.
- Use a folding airer indoors. A basic clothes airer costs nothing to run. Position it near a radiator, in a sunny room, or run it overnight when the heating is on anyway. Cheap airers and pegs turn up regularly on the Wilko and Dunelm deal pages.
- Consider a heated airer. At around 200-300W, a heated airer costs roughly 6-8p an hour to run and dries a full load in several hours for a fraction of what a tumble dryer charges per load.
- Try the dehumidifier trick. Drying clothes indoors releases litres of moisture, which is bad news for both your walls and your heating bill. Running a dehumidifier in a closed room with your airer dries clothes cheaply, kills condensation and protects against damp – one of the most underrated money-saving combos in the UK.
- Crank up the spin speed. A higher spin on the washing machine extracts more water mechanically, which is far cheaper than extracting it with heat. Shifting from 800 to 1200 rpm can knock a meaningful chunk off drying time.
If you must use the tumble dryer
Sometimes – in winter, with a sick child, or before work when you need clothes now – the tumble dryer is the only sensible answer. Make it cheaper:
- Clean the fluff filter every single time. A clogged filter forces the machine to run longer and hotter, costing more per load and creating a fire risk.
- Do not overload. Air needs to circulate – and spin the washing properly first so the dryer starts with less water to remove.
- Buy heat pump if you are replacing. Heat pump dryers use roughly half to a third of the electricity of a condenser model per cycle. They cost more upfront, so run the numbers with our cost per use calculator before committing.
- Never pay full ticket price. Big appliance discounts cluster around Black Friday, the January sales and bank holidays. Watch the Currys and Amazon deal pages, and do not ignore secondhand – a lightly used heat pump dryer on eBay can undercut a new condenser by a wide margin.
Time your washing right
On a standard single-rate tariff it makes no difference when you press start, but millions of UK households are on time-of-use tariffs such as Economy 7 or smart off-peak rates. If that is you, the cheapest electricity often sits overnight – use the delay timer and run the wash while you sleep. Overnight savings only exist if your tariff actually has cheaper off-peak rates, so check before assuming.
Keep your machine running efficiently
A poorly maintained machine quietly costs more to run – limescale on the element makes heating slower and pricier, especially in hard water areas. A few cheap habits protect it:
- Run a hot empty service wash with soda crystals or a washing machine cleaner once a month.
- Pull out and rinse the detergent drawer regularly – old soap sludge breeds mould and wastes detergent.
- Wipe the door seal after the last wash of the day and leave the door ajar so the drum dries out.
- Check and clean the pump filter a few times a year so the machine drains properly.
These five-minute jobs keep the machine near its designed efficiency for longer, delaying an expensive replacement – and a cleaner machine washes better at 30 degrees too.
Final thoughts
Cheap laundry is not about wearing things twice or cutting back on hygiene – it is about refusing to overpay for water heat, detergent and hot air. Wash at 30 degrees, wait for full loads, buy detergent on offer and dose it properly, line dry or airer dry whenever you can, and keep your machine in good health so it runs cheap for years. Do all of that and the laundry line on your budget can shrink by well over £100 a year.
