Do we really need to dump our old inefficient appliances?
Replacing a working washing machine with a more efficient model saves a modest amount on running costs – typically under £15 per year in energy savings. At current appliance prices of £300 to £600 for a replacement, the payback period from energy savings alone is 20 to 40 years. The case for replacement on energy grounds alone is weak unless the appliance has already reached the end of its reliable service life.
Campaigns encouraging households to replace working appliances with more energy-efficient models are a regular feature of the domestic appliance market. The arguments deserve careful examination – both the claimed savings and the costs that are not always included in the comparison.
What the Energy Savings Actually Are
The energy saving from replacing a 10-year-old washing machine with a modern high-efficiency model is approximately 40 to 50 kilowatt-hours per year – roughly a 15 to 20% reduction in the machine’s annual energy consumption.
The 17% figure illustrates a common issue with percentage-based energy claims. A 17% saving sounds substantial – but 17% of a small number is still a small number. The annual cost to run a modern washing machine is approximately £25 to £50 depending on usage. A 17% saving on this is under £10 per year. Percentage claims require the underlying figure to be meaningful.
What Is Left Out of the Calculation
Campaign-based comparisons between old and new appliances typically show the energy consumption difference between the two machines. They do not typically include:
Costs not included in standard replacement calculations
- The carbon cost of manufacturing the new appliance – including raw material extraction, component production, and factory energy use
- Logistics and transport of the new appliance from factory to retailer to household
- Collection and transport of the old appliance to a recycling facility
- The energy and resources required to process the old appliance – recovering refrigerant from cooling appliances, smelting metals, processing plastics
- Disposal of the new appliance’s packaging – significant volumes of polystyrene and cardboard
Industry research has argued that 90% of a domestic appliance’s lifetime environmental impact comes from the energy it uses during operation, not manufacture or disposal. This figure is widely cited in replacement campaigns. However, it describes the lifetime impact of the old appliance – which has already occurred. The relevant question for a replacement decision is the marginal cost of replacing now versus continuing to use the working appliance for a few more years.
Who Is Promoting Replacement?
The “Time to Change” campaign that produced much of the data used in appliance replacement arguments was promoted substantially through AMDEA – the Association of Manufacturers of Domestic Appliances. This is the trade body representing the manufacturers who benefit commercially from increased appliance replacement. This does not make the underlying energy efficiency data wrong, but it is relevant context when evaluating how the data is presented and emphasised.
Some supporting data came from the Energy Saving Trust and other bodies with no commercial interest in appliance sales – this lends more credibility to the raw figures. The question is whether the framing of the savings as compelling reasons to replace working machines is a balanced assessment.
When Replacement Does Make Sense
The case for replacing a working appliance on energy grounds alone is generally weak. The case is stronger in specific circumstances:
When replacing an appliance is genuinely worthwhile
- The appliance has developed a fault and the repair cost approaches or exceeds the replacement cost – replacing at this point adds no additional environmental cost beyond what the failure already necessitates
- The appliance is very old – 15 or more years – and the energy difference compared to current models is significantly larger than the 10-year comparison
- The appliance is a large refrigeration unit that runs continuously – the cumulative energy saving over a long period is larger than for a machine that only runs when used
- A household is choosing between purchasing a new appliance regardless – in which case the energy efficiency of the replacement is absolutely a relevant criterion

Frequently Asked Questions
How much does replacing a washing machine save on energy bills?
Replacing a 10-year-old washing machine with a modern high-efficiency model saves approximately 40 to 50 kilowatt-hours per year – worth approximately £11 to £13 at current UK electricity rates. The saving increases if the old machine is significantly older. At a replacement cost of £300 to £600, the payback period from energy savings alone is 25 to 50 years – making the economics of replacement on energy grounds alone very weak unless the appliance would be replaced anyway.
Is it better for the environment to replace an old appliance?
This is more complex than it appears. The energy saving from using a newer appliance is real. However, manufacturing, transporting, and disposing of appliances all have environmental costs that are not typically included in campaign comparisons. For a working appliance with several years of service life remaining, the environmental benefit of the energy saving may not outweigh the impact of premature replacement. When an appliance needs replacing anyway, choosing the most energy-efficient option is clearly worthwhile.
Should I replace a working 10-year-old washing machine?
On energy grounds alone, probably not – the annual energy saving is under £15 and the payback period is very long. If the machine is developing reliability issues or the repair costs are significant, the calculation changes – replacing at this point adds no additional environmental cost beyond what the failure already requires. If the machine is working well and producing good results, keeping it running until it genuinely needs replacement is typically the most economical and arguably the most environmentally sound option.
Do I need to use fabric softener on towels?
If laundry is going straight into the tumble dryer, fabric softener is largely unnecessary. The mechanical tumbling action in warm air softens fabric naturally. Skipping softener on tumble-dried loads saves money, reduces chemical use, and – for towels specifically – maintains their absorbency, which fabric softener reduces over time.
Why Tumble Drying Softens Laundry Without Fabric Softener
Fabric softener works by coating fibres with a thin layer of lubricating agents that make them feel soft to the touch. Tumble drying achieves a similar result through a different mechanism – the repeated tumbling of laundry in warm air physically relaxes the fibres and prevents them from drying stiff and compacted, which is what causes the characteristic roughness of line-dried laundry.
The result is that tumble-dried laundry emerges soft without any chemical assistance. Independent comparisons between loads dried with and without fabric softener after tumble drying consistently show no significant difference in softness – provided the load is not over-dried.
The softening effect of tumble drying works best when laundry is dried to the correct level of dryness and removed promptly. Over-dried laundry – left in a hot drum for too long after the cycle ends – can feel rough regardless of whether softener was used. Use a timed or sensor-dry programme appropriate to the load.
The Case Against Fabric Softener on Towels
There is an additional reason to skip fabric softener specifically on towels, regardless of whether they are tumble dried or line dried.
What fabric softener does to towels
Fabric softener leaves a coating on fibres that makes them feel smooth and soft. On towels, this coating also reduces the surface’s ability to absorb water – which is the primary function of a towel. Regular use of fabric softener on towels gradually reduces their absorbency over time.
Towels without fabric softener
Towels washed and tumble dried without fabric softener maintain their absorbency fully. They may feel slightly less soft initially but this is less noticeable than the gradual loss of absorbency from regular softener use. If the texture feels too rough, the solution is shorter drying times and prompt removal from the drum rather than adding softener.
Line Drying Without Fabric Softener
The softening effect of tumble drying does not apply to line drying. Laundry dried on a line without fabric softener may feel noticeably stiffer than it would with softener – particularly items like towels and cotton shirts. Some practical approaches:
-
Try reducing the amount of softener rather than eliminating it entirely – even a smaller dose provides some softening effect on line-dried laundry. -
Do not leave laundry on the line longer than necessary. Over-drying on a line stiffens fibres. Remove promptly when dry. -
Give line-dried laundry a short tumble at low heat (10 to 15 minutes) after bringing it in. This relaxes the fibres and softens the texture without the full energy cost of a complete tumble dry cycle.
Fabric Softener on Children’s Nightwear
Fabric softener reduces the flame-resistant properties of garments designed to be fire-retardant – including children’s nightwear labelled as flame-resistant. Do not use softener on these items. See our full guide on fabric softener and children’s sleepwear.

Frequently Asked Questions
Do I need fabric softener if I tumble dry?
No. Tumble drying softens laundry through the mechanical action of items tumbling in warm air, which relaxes the fibres and prevents the stiffness associated with line drying. Fabric softener is not needed for tumble-dried laundry to feel soft, provided the load is not over-dried. Skipping softener on tumble-dried loads saves money and, for towels, maintains their absorbency.
Does fabric softener reduce the absorbency of towels?
Yes. Fabric softener works by leaving a lubricating coating on fibres. On towels, this coating reduces the surface area available to absorb water. Regular use of fabric softener on towels gradually reduces their absorbency over time. This is one of the stronger reasons to avoid softener on towels specifically – and tumble drying provides an alternative softening mechanism that does not compromise absorbency.
Will line-dried laundry be rough without fabric softener?
Possibly, depending on the fabric and drying conditions. Laundry dried on a line without softener can feel stiffer than tumble-dried laundry or softener-treated laundry. For towels and cotton items, a brief 10 to 15 minute tumble at low heat after line drying relaxes the fibres significantly. Reducing rather than eliminating softener is another option for line-dried loads where texture matters.
Don’t misconnect your washing machine or dishwasher to the plumbing
There are two separate drainage systems under most UK streets: one for waste water (toilets, sinks, appliances) which is treated; one for rainwater which runs untreated into rivers. Connecting appliance waste water to the rainwater system is a misconnection. Garages and outbuildings are particularly at risk because they are rarely connected to the sewerage system – making a misconnection easy to make accidentally.
If the waste water pipe from a washing machine or dishwasher is connected to the rainwater drainage system rather than the sewerage system, harmful detergent chemicals drain untreated into local rivers and streams. This is called a plumbing misconnection. It is illegal and it may have happened before you moved in – which does not change the current householder’s responsibility to correct it.
The Two Drainage Systems
Most UK properties are served by two entirely separate underground drainage systems that must never be connected to each other.
Sewerage system (foul water drain)
Receives waste water from toilets, baths, sinks, washing machines, and dishwashers. This water is pumped to a treatment works where harmful substances are removed before the treated water is discharged. The external pipe serving this system is typically a large 4-inch stack pipe on the outside wall of the property.
Surface water drain (storm drain)
Receives only rainwater from roof guttering and external surfaces. This water runs untreated directly into local rivers and streams. It connects to grates at the base of fall pipes from the guttering. No waste water from appliances, sinks, or toilets should ever enter this system.
Why Misconnections Are Common
Misconnections often happen because the two drainage systems look similar from the outside and their connections can be physically close together. The problem is particularly common in garages and outbuildings, which are rarely connected to the sewerage system. Anyone installing a washing machine in a garage and connecting the drain hose to the nearest available pipe or grate risks connecting to the rainwater drain rather than the foul water system.
Outbuildings and garages are almost never connected to the sewerage system. Any grate or pipe in a garage floor or at the base of guttering fall pipes goes to the surface water drain. Connecting a washing machine waste pipe to any drainage point in a garage without verifying it connects to the foul water system is likely to result in a misconnection. See our guide on putting a washing machine in a garage for what to check before installing.
How to Check for a Misconnection
-
Locate the main 4-inch waste stack pipe on the outside of the property.
This is usually a large plastic pipe (typically white or grey) running vertically down an outside wall close to the bathroom or kitchen. All waste water from the property should ultimately connect to this pipe or to an approved grate directly beside it.
-
Check that no guttering fall pipes connect to the waste stack.
Rainwater from roof guttering must not discharge into the foul water system. If any fall pipe from the roof guttering connects to the main stack pipe, this is a misconnection in the other direction – rainwater overloading the sewerage system.
-
Trace the waste pipe from the washing machine or dishwasher.
Follow the drain hose or waste pipe from the appliance to where it exits the property. Confirm it connects to the main foul water stack pipe or to a grate that is itself connected to that system – not to a grate at the base of a guttering fall pipe.
-
Check grates near guttering fall pipes.
A grate at the base of a fall pipe receives rainwater from the roof. No appliance or sink pipe should connect to or discharge into this grate. If there is any appliance pipe near a guttering fall pipe grate, verify they are separate systems before assuming the connection is correct.
-
If in doubt, consult a plumber or the local water authority.
The local water authority may be able to advise or inspect drainage connections. A qualified plumber can trace the drainage routes and confirm whether any misconnection exists.
Consequences of a Misconnection
Environmental pollution
Waste water from washing machines and dishwashers contains detergents, bleaching agents, fabric softener, and other chemicals. When this water enters the surface water drain, it flows untreated directly into local rivers and streams, polluting the water and harming aquatic life.
Flash flooding risk
Appliance waste water discharged into the surface water system during heavy rain adds to the volume of water the storm drains must handle. Combined with heavy rainfall, this can contribute to surface water flooding in local streets.
Legal responsibility
A plumbing misconnection is illegal regardless of when it occurred or who made it. The current householder is legally responsible for ensuring drainage connections are correct. A misconnection discovered when selling a property may require correction before completion.

Frequently Asked Questions
How do I know if my washing machine is misconnected?
Trace the waste pipe from the machine to where it connects to the drainage system. It should connect to the main foul water stack pipe (the large 4-inch pipe on the outside wall near the bathroom or kitchen) or to a grate that connects to that system underground. If it connects to a grate at the base of guttering fall pipes, or to any drain that receives rainwater, it is misconnected.
What happens if I have a misconnection?
Detergent chemicals and other waste from the appliance drain untreated into local rivers and streams via the surface water system. During heavy rain, the extra water volume can contribute to flash flooding. A misconnection is also illegal – the current householder is responsible for correcting it regardless of when it was made or by whom.
Can I put a washing machine in a garage and drain it correctly?
Yes, but it requires connecting the waste pipe to the foul water system – which garages typically are not connected to. A new run of waste pipe to the foul water stack, or a specialist pump system, is usually needed. Do not connect to any existing grate in the garage floor or at the base of guttering – these are almost certainly surface water drains. See our full guide on washing machines in garages before installing.
How to reduce energy costs of running white goods appliances
White goods – particularly those with heating elements such as washing machines, tumble dryers, dishwashers, and ovens – account for a significant proportion of household electricity use. Appliance efficiency has improved considerably over decades, but checking the energy tariff being paid is often a more impactful way to reduce running costs than replacing a working appliance with a marginally more efficient one. Do not make the mistake of buying a lower quality appliance purely to save a small amount of energy if it will not last as long.
Where White Goods Energy Use Comes From
Fridges and freezers run continuously but are relatively efficient. The appliances with the biggest energy impact are those with heating elements – washing machines, tumble dryers, dishwashers, and ovens. In each case, the heating element accounts for the vast majority of the electricity consumed per cycle.
This is why running temperature is so significant for washing machines – a 40 degree wash uses substantially less energy than a 60 degree wash, because heating the water is where most of the electricity goes. Modern appliances have become considerably more efficient at each temperature, but the physics of heating water has not changed.
Appliance Efficiency Has Plateaued
Years of successive efficiency improvements to appliance design have produced diminishing returns. The difference in running cost between an A-rated appliance from several years ago and the best-rated equivalent today is often modest in practical terms. Replacing a functioning appliance purely to gain a small efficiency improvement rarely makes financial sense when the embodied energy of manufacturing a replacement is factored in.
An appliance with a slightly better energy rating but shorter service life is not necessarily a better environmental or financial choice than a well-built machine with a slightly lower rating that lasts significantly longer. Build quality, reliability, and repairability are as important as the energy label figure. See our guide on whether replacing old appliances saves energy for a fuller analysis.
Energy Tariffs and the Unit Price of Electricity
The running cost of any appliance depends on two things: how much electricity it uses, and how much each unit of electricity costs. Appliance efficiency improvements reduce the first number. Checking the energy tariff addresses the second – and the second is often a larger variable than the first.
The UK energy market has changed significantly since 2021. Ofgem’s energy price cap now limits what suppliers can charge domestic customers on default tariffs, which has changed the dynamics of switching. However, tariff structures and available deals still vary between suppliers, and it remains worth reviewing what is being paid at least once a year.
-
Check comparison sites for current tariff deals. Sites such as Uswitch and MoneySuperMarket compare available tariffs by postcode and usage. The Ofgem price cap applies to default and standard variable tariffs, but fixed rate deals and green tariffs may be available at different rates depending on the market at the time of checking. -
Review the tariff at least once a year. Energy prices and the available deals change regularly. Setting a reminder to check annually ensures overpaying on a default tariff for years at a time is avoided. -
Check whether a smart meter and off-peak tariff is available. Some suppliers offer time-of-use tariffs where electricity is cheaper during off-peak hours (typically overnight). Running the washing machine or dishwasher on a delay timer during these hours can meaningfully reduce running costs for high-frequency users.
Simple Appliance Use Habits That Reduce Energy Use
Wash at lower temperatures
Modern detergents work effectively at 30 and 40 degrees for normally soiled laundry. Reducing the wash temperature from 60 to 40 degrees cuts the energy used per cycle significantly. Reserve higher temperatures for heavily soiled loads and hygiene washes.
Run full loads
The energy cost of a washing machine or dishwasher cycle is largely fixed regardless of load size. A half-empty machine uses nearly as much electricity as a full one. Running fewer full loads rather than more partial loads reduces total energy consumption.
Line dry where possible
The tumble dryer is one of the most energy-intensive domestic appliances. Drying laundry on a line or airer when conditions allow eliminates this energy use entirely. Even partial line drying before a short tumble cycle reduces consumption.
Use the eco programme
Eco programmes on washing machines, dishwashers, and tumble dryers are designed to minimise energy and water use per cycle. They typically take longer but use significantly less electricity than faster or higher-temperature programmes.

Frequently Asked Questions
Does replacing a washing machine with a more efficient one save money?
The saving depends on the difference in efficiency between the old and new machine and how frequently it is used. For a washing machine used several times a week, the annual energy saving from replacing a moderately efficient model with the most efficient equivalent is typically modest – often less than £20 to £40 per year. Against the purchase cost of a new machine, the payback period is long. Checking the energy tariff and running the machine on lower temperature programmes often delivers a larger and more immediate saving.
What uses the most electricity in a washing machine?
The heating element – the component that heats the water during the wash cycle – accounts for the majority of a washing machine’s electricity use per cycle. This is why wash temperature has such a significant effect on running costs. The motor, pump, and controls use a comparatively small amount of electricity. Modern heat pump technology in tumble dryers applies a similar principle – using less electricity to generate the same heat output.
Smoke free public places law has unexpected benefits for washing machines
The 2007 ban on smoking in enclosed public places in England had an unexpected environmental side effect: clothes worn to pubs, restaurants, and other venues no longer returned home smelling of smoke. For many people this removed a common trigger for unnecessary washing. Fewer unnecessary washes means less water use, less energy, less detergent, and less wear on washing machines and tumble dryers.
The Smoking Ban’s Unexpected Laundry Effect
When the Health Act 2006 came into force in July 2007, banning smoking in enclosed public places across England (Scotland, Wales, and Northern Ireland introduced similar legislation around the same time), the intended benefits were public health focused. One environmental benefit that attracted less attention was the effect on domestic laundry habits.
Before the ban, clothes worn to a pub, bar, or restaurant for a few hours would return home permeated with cigarette smoke. Even lightly worn items that were otherwise clean were routinely put straight into the wash basket. The smoke smell left no practical alternative to washing.
After the ban, those same items – worn for an evening out but otherwise clean – could reasonably be returned to the wardrobe. The trigger for washing them was gone.
The Cumulative Environmental Impact
A single avoided wash cycle is trivial. Multiplied across millions of households, the cumulative effect is significant.
Approximate water use per washing machine cycle
Approximate electricity use per cycle (depending on temperature)
UK households with washing machines – multiplier for any change in average wash frequency
Fewer washes also means less tumble drying, less detergent, and reduced appliance wear
The dry cleaning industry reported a noticeable drop in custom after the smoking ban came into force. Suits and jackets that had previously required regular cleaning after pub lunches or evening events no longer accumulated smoke residue between cleans – reducing the frequency with which dry cleaning was needed.
Washing More Often Than Necessary
The smoking ban example illustrates a broader point: a significant proportion of domestic laundry is washed because of smell alone rather than visible soiling. When the smell trigger is removed, the same items can comfortably be worn again or returned to the wardrobe.
Reducing unnecessary washing is one of the most straightforward ways to reduce the environmental impact of domestic laundry. It also reduces wear on clothing, extends garment life, and reduces wear on the washing machine itself. Modern detergents and washing machines are effective at cleaning genuinely soiled items – not every item worn for a few hours needs to go through a full wash cycle.
Items that are visibly soiled, have been in contact with sweat over extended wear, or have been worn in situations where hygiene matters should be washed normally. Items worn briefly in clean environments with no sweat or visible soiling – particularly outer layers – can often be aired and returned to the wardrobe without a full wash cycle.

Eco-labels suggestion
Energy efficiency labels on washing machines rate appliances on energy, water, wash performance, spin, and noise. What they do not rate is how long the appliance is likely to last. A washing machine that scores an A rating but lasts only 4 years causes more environmental harm overall than one rated slightly lower that lasts 20 years. Adding an expected lifespan indicator to energy labels would give consumers a genuinely complete picture.
What Energy Labels Currently Measure
EU energy efficiency labels (which remain in use in the UK in updated form) rate washing machines across several parameters: energy consumption per cycle, water consumption, wash performance, spin drying efficiency, and noise level. These are all useful measures of how the machine performs during its operating life.
What the label does not measure is how long that operating life is likely to be. A machine rated A for energy that lasts five years uses significantly more total energy over a 20-year period than a machine rated B that lasts 20 years. The label captures annual performance but not total lifetime impact.
The Missing Indicator: Expected Lifespan
A poorly built machine that will be scrapped within five years can achieve the same A energy rating as a well-built machine designed to last 20 years. The energy label gives no indication of this difference. Yet the environmental cost of manufacturing, transporting, and disposing of four machines over a 20-year period massively exceeds the marginal energy saving per cycle on the better-rated but shorter-lived machine.
Adding an expected lifespan indicator to the energy label – based on manufacturer reliability data, independent testing, or design standards – would change how many consumers approach the purchase decision. Consider the effect of seeing the following side by side at the point of sale:
| Machine | Price | Expected lifespan | Cost per year | Machines needed over 20 years |
|---|---|---|---|---|
| Appliance X | £850 | 15 to 20 years | ~£48 | 1 |
| Appliance Y | £299 | 3 to 5 years | ~£75 | 4 to 6 |
| Appliance Z | £575 | 7 to 10 years | ~£65 | 2 to 3 |
The cheapest machine is actually the most expensive over a 20-year period, and produces three to five times as much manufacturing and disposal waste. A lifespan indicator on the label would make this visible at the point of sale rather than invisible to most buyers.
Bigger Drum and Faster Spin Is Not Always Better Value
A common buying pattern is to compare two machines and conclude the one with a larger drum and higher spin speed at a lower price is better value. The specification comparison on the energy label encourages this reading. A lifespan indicator would add the dimension that is currently missing:
| Machine | Price | Drum / Spin | Expected lifespan | Cost per year |
|---|---|---|---|---|
| Machine A | £750 | 6kg / 1400rpm | 20 to 25 years | ~£34 |
| Machine B | £389 | 7kg / 1600rpm | 3 to 8 years | ~£70 |
Machine B appears to offer more – larger drum, faster spin, lower price. Without lifespan data, most consumers would choose it. With lifespan data, the cost-per-year comparison tells a different story.
Premium-priced machines are routinely dismissed as “expensive” by consumers who cannot see what they are getting for the higher price beyond surface specifications. A lifespan indicator on the label would directly explain the price difference for many machines – and give buyers the information needed to make a genuinely informed choice rather than defaulting to the lowest upfront cost. See our guide on how long washing machines should last.
The Current Label’s Limitations
What the energy label misses
- Build quality and repairability are not rated. A machine that cannot be economically repaired when it fails is less environmentally friendly than one that can, regardless of its energy rating
- Longevity is not rated. A shorter-lived machine requires more manufacturing cycles per decade of service than a longer-lived one, with corresponding environmental cost
- The label rewards per-cycle efficiency but not lifetime efficiency. A machine that uses 5% less energy per cycle but lasts half as long is less efficient over its service life
- Manufacturers can design machines specifically to score well on the label tests without improving real-world performance. Scores have converged as manufacturers optimise for the rating rather than for genuine improvement
For the current energy label series and what the existing ratings mean, see our guides on what energy labels mean and how designing for eco labels can be misleading.

Frequently Asked Questions
Why don’t energy labels show how long a washing machine will last?
Current EU and UK energy labels rate washing machines on measurable per-cycle performance metrics: energy use, water use, wash quality, spin efficiency, and noise. Lifespan is not currently included, though it is arguably the most important environmental factor. A machine that lasts 20 years has far lower lifetime environmental impact than one rated slightly better per cycle but replaced every five years.
Is a cheaper washing machine actually worse value over time?
Often yes, when lifespan is factored in. A budget machine at £300 that lasts five years costs £60 per year. A premium machine at £800 that lasts 20 years costs £40 per year – and involves one machine being manufactured and disposed of instead of four. The upfront price comparison is misleading without the lifespan context.
Would a lifespan indicator on energy labels change buying decisions?
For many buyers, yes. The specification comparison on current labels makes a larger drum and higher spin speed at a lower price look like better value – which it often is not when lifespan is included. Seeing cost per year alongside purchase price, and machines needed per decade, would give buyers the information currently missing from the point-of-sale comparison.
