Best Ways to Save on Electricity in 2027
In this post
Electricity bills feel mysterious to many households because the cost arrives as a single number, while the usage behind it is spread across dozens of small decisions every day. Heating, cooling, hot water, lighting, cooking, laundry, and dozens of devices all draw power, often invisibly. The good news is that saving electricity in 2027 does not require living in the dark or buying expensive equipment all at once. It requires understanding where your home actually uses power, fixing the largest waste first, and building a few habits that cost nothing but save steadily. This guide works through the biggest electricity uses in a typical home, from heating and cooling to standby power, and shows which changes pay back fastest.
The first step is to read your bill and your meter, not just pay the total. Most bills show total usage over a period, and many suppliers offer online usage charts by day or hour. A sudden rise often points to a specific cause, such as a new appliance, a change in heating settings, or a faulty device. If your supplier offers a smart meter or an energy monitor, use it for a few weeks to learn your home’s pattern. You may discover that one old appliance, a constantly running heater, or a habit such as leaving lights on in empty rooms costs far more than you assumed. Without that picture, saving advice is guesswork.
The second step is to focus on size. In most homes, heating and cooling, water heating, and large appliances dominate electricity use, while phone chargers and small gadgets use relatively little. That means turning off a phone charger saves pennies, while adjusting heating by one degree, fixing draughty windows, or replacing an old fridge can save far more. This guide therefore starts with the big uses and moves to the small ones. Small habits still matter, especially when many people in a household adopt them, but they should not distract from the large, boring wins that actually move the bill.
The third step is to think in terms of payback. Some changes cost nothing, such as shorter showers or using a lid on a pan. Some cost a little, such as LED bulbs or a draught excluder. Some cost more, such as a new efficient appliance or insulation, and should be timed to when the old item needs replacing anyway. A change that saves a small amount but costs a lot may never pay back, while a free habit that saves a little every day can outperform an expensive gadget over a year. The best electricity saving plan mixes free habits, cheap fixes, and well-timed upgrades.
Heating and Cooling: The Biggest Electricity Users
Heating and cooling usually dominate home energy use, because they run for hours and power large equipment. The cheapest saving is often a thermostat adjustment. Lowering heating by one degree in winter, or raising cooling by one degree in summer, usually reduces energy use noticeably while remaining comfortable, especially if you wear suitable clothing indoors. Programmable or smart thermostats help by heating or cooling only when rooms are occupied, rather than running all day for an empty home. Setting a schedule that matches real life, and reviewing it when routines change, prevents the common waste of heating an empty house.
Draughts and insulation matter just as much as the heater itself. Warm air escaping through gaps around doors, windows, and loft hatches forces heating to work harder, while poor insulation lets heat pass through walls and roofs. Simple fixes such as draught strips, closing curtains at night in winter, and keeping radiator vents clear can help immediately. Larger improvements, such as loft or wall insulation, cost more but can transform a cold home and pay back over years through lower bills and greater comfort. A home energy assessment, where available, can identify the most effective improvements for your specific building rather than guessing.
How you use heating equipment also matters. Closing doors to unused rooms, but not blocking airflow completely where ventilation is needed, helps heat stay where people are. Portable electric heaters are useful for one room for a short time, but heating a whole home with them is usually expensive compared with a central system, because they convert electricity directly to heat in a small area. Fans in summer use far less electricity than air conditioning, and using a fan with open windows at night can cool a home before the heat of the day. When air conditioning is needed, keeping filters clean, closing curtains against direct sun, and setting a moderate temperature all reduce running costs.
Hot Water, Laundry, and Kitchen Electricity
Hot water is a hidden electricity user, because showers, baths, dishwashing, and washing machines all depend on it. Shorter showers are the simplest saving, and a low-flow showerhead can reduce hot water use without making showers unpleasant. Washing clothes in cold or warm water, rather than hot, saves heating energy for most everyday loads, and modern detergents are designed to work at lower temperatures. Running washing machines and dishwashers only with full loads also matters, because a half load uses nearly as much energy as a full one. Drying clothes outdoors or on a rack, where climate allows, avoids the high energy cost of tumble drying, which is one of the most power-hungry household appliances.
In the kitchen, cooking methods affect electricity use more than most people expect. A lid on a pan keeps heat in and cooks food faster. Matching pan size to the burner or hob ring prevents wasted heat. Small appliances such as a microwave, slow cooker, or air fryer often use less energy than heating a large oven for a small meal, although the best choice depends on the dish and portion size. Batch cooking, where several meals are prepared at once and stored safely, can also reduce repeated oven use. Defrosting food in the fridge overnight, rather than in a microwave or under hot water, saves energy and is safer for food.
Fridges and freezers run all day, every day, so their efficiency matters. Keep fridge temperature at the manufacturer’s recommended setting, usually around a few degrees above freezing for the fridge section, and avoid setting it colder than needed. Let hot food cool before putting it in the fridge, keep door seals clean so cold air does not leak, and avoid leaving doors open while deciding what to take. An old, inefficient fridge in a garage or as a second fridge can cost more to run than it saves in storage, so consider whether a second fridge is truly needed. When replacing a fridge, the energy label and size matter: a larger model than needed will use more power for empty space.
Lighting: The Easiest Win in Most Homes
Lighting is the easiest electricity saving for most households, because LED bulbs now provide the same brightness as old bulbs while using a fraction of the power and lasting far longer. Replacing the most-used bulbs first, such as kitchen, living room, and hallway lights, gives the fastest payback. Less-used bulbs, such as in a rarely visited cupboard, can wait. When buying LEDs, check brightness in lumens rather than wattage, because wattage no longer indicates brightness reliably. Colour temperature also matters: warm white suits living areas, while cooler white suits workspaces, and choosing the right tone prevents the harsh feeling that puts some people off LEDs.
Habits amplify the bulb saving. Turning lights off when leaving a room remains one of the simplest savings, especially in homes where lights are left on out of habit. Motion sensors or timers can help in hallways, bathrooms, and outdoor areas where lights are often forgotten. Daylight is free lighting: opening curtains, keeping windows clean, and arranging workspaces near windows can reduce daytime lighting needs. Outdoor lighting should be used only where needed for safety, with timers or sensors so it does not burn all night. A single outdoor light left on all night, every night, can cost more over a year than many people expect.
Smart lighting can help, but it is not necessary for saving. A smart bulb that is left on remotely still uses power, and the savings come from control and scheduling, not from the word smart. If you already use smart lights, set schedules, dim lights where full brightness is unnecessary, and group lights so one command turns off a whole room. If you do not, simple switches, timers, and habits achieve most of the same saving at far lower cost. The goal is light only where and when it is needed, at the brightness actually required.
Phantom Loads and Everyday Devices
Phantom load, also called standby power, is the electricity used by devices that appear off but remain ready to respond to a remote control, maintain a clock, or stay connected to a network. Televisions, game consoles, printers, chargers, and older set-top boxes can all draw standby power. Individually, each draw is small. Across a home with many devices, the total can become noticeable over a year. The simplest fix is to switch devices fully off at the wall when they will not be used for hours, especially overnight or when leaving home for a period.
Power strips with switches make this easier. Grouping entertainment devices on one strip, or computer equipment on another, allows one switch to cut power to several devices at once. Smart plugs can automate this, turning off a group at a set time, but they themselves use a small amount of power, so they are best used for groups with significant standby draw rather than for a single phone charger. Unplugging chargers when not in use is good practice, although modern chargers use very little standby power. The bigger saving comes from large entertainment and office setups, not from chasing every tiny charger.
Everyday device habits also add up. Laptops generally use less power than desktop computers, and putting a computer to sleep when away from it, rather than leaving it fully on, saves energy. Lowering screen brightness slightly, where comfortable, reduces power use, especially on large monitors. Printers, scanners, and other office equipment should be switched off when not needed, rather than left ready all day. None of these habits alone will transform a bill, but together they remove a constant background drain that runs even when the household is asleep or away.
Tariffs, Meters, and Smarter Buying
The price you pay per unit of electricity matters as much as how much you use. Tariffs differ by supplier, region, and plan type, and many households stay on an expensive default plan out of habit. Comparing tariffs periodically, especially when a fixed deal ends, can save money without using any less electricity. Time-of-use tariffs, where electricity costs less at off-peak times such as overnight, can benefit households that can shift flexible uses, such as laundry, dishwashing, or electric vehicle charging, to cheaper hours. They can cost more, however, if most use remains at peak times, so check your usage pattern before switching.
Smart meters, where available, show usage in near real time and remove estimated bills, which helps households see the effect of changes quickly. If your supplier offers an energy monitor or app, use it to test a change for a week: for example, compare a week with shorter showers and full laundry loads against a previous week. That feedback is more motivating than general advice, because it shows your home’s actual result. If a smart meter is not available, reading a traditional meter weekly and noting the number in a notebook or phone achieves a similar learning effect at no cost.
When buying new appliances, the energy label is a practical tool. It shows expected annual energy use and allows comparison between models of similar size and type. A cheaper appliance that uses much more electricity can cost more over its lifetime than a slightly more expensive efficient model. Size also matters: buying the smallest appliance that meets real needs usually saves both purchase cost and running cost. For large purchases, calculate a rough lifetime cost by adding purchase price to expected yearly running cost multiplied by expected years of use. That simple calculation often changes the buying decision.
Renters, Landlords, and Homes You Cannot Renovate
Renters face a special challenge, because the largest energy improvements, such as insulation, new windows, or a new heating system, usually belong to the landlord, not the tenant. That does not mean renters cannot save. The most effective renter-friendly measures are portable and reversible: LED bulbs that can be taken when moving, draught strips on doors, thick curtains, rugs on cold floors, and smart plugs or timers that travel to the next home. A renter should also check whether heating controls are understood and used correctly, because many tenants inherit a heating system they were never shown how to program, and a single tutorial can prevent months of waste.
Communication with landlords helps when improvements are needed. A polite, written request that explains a problem, such as a draughty window, a broken seal, or an inefficient heater, and notes the benefit to the property as well as the tenant, is more effective than a complaint alone. In many places, landlords have legal duties regarding energy efficiency and habitable conditions, although rules vary widely, so tenants should check local official guidance before assuming rights. Keeping a record of requests and responses protects both sides if a dispute arises. Where a landlord agrees to an improvement, tenants can offer flexible access and a clear timeline, which makes agreement easier.
Shared homes and flats add another layer, because bills may be split among housemates with different habits. A shared agreement at the start of a tenancy, covering heating settings, laundry routines, and how bills are split, prevents most arguments. A visible meter reading routine, such as a weekly photo in a shared chat, makes usage transparent without policing individuals. When one housemate works from home all day while others are out, a fair split may need discussion, because usage is genuinely uneven. Honest conversation early is cheaper than resentment later, and a household that agrees on a few simple rules will save more than a household where one person secretly tries to control everyone else’s usage.
My Take:
My opinion on saving electricity is that most households do not have an electricity problem. They have an invisibility problem. Power is silent, automatic, and billed weeks later, so waste feels free in the moment. The moment you can see usage, whether through a smart meter, a weekly meter reading, or simply a bill broken down by habit, behaviour changes without any sacrifice. I think the first investment any household should make is attention, not equipment. A week of noticing when heating runs, when lights stay on, and which appliances run half-empty teaches more than a shelf of energy-saving gadgets.
I also believe the biggest savings are boring, and that is why they are ignored. Thermostat settings, draught strips, full laundry loads, and LED bulbs do not make exciting content, but they move bills. Gadgets that promise dramatic savings often disappoint, because they address small uses while large uses continue unchanged. I would always fix heating, hot water, and large appliances before buying a smart plug or an energy monitor for a phone charger. Order matters. Saving on the small stuff first feels productive, but it is often procrastination dressed as efficiency.
On comfort, my view is that saving electricity should not mean suffering. A cold, dark home is not an efficient home. It is an unpleasant one, and people will abandon saving habits that make life worse. The goal is to waste less while living well: heat the rooms people use, light them adequately, and wash clothes effectively, but stop heating empty rooms, lighting empty spaces, and running half-empty machines. I think that framing matters, because it turns saving from deprivation into good management. A well-managed home is comfortable and cheaper. A deprived home is cheaper for a week and then abandoned.
I am sceptical of advice that blames individuals for bills shaped by building quality and tariffs. A household in a poorly insulated home, or on an expensive default tariff, can follow every habit perfectly and still pay a high bill. That does not make habits useless, but it means the biggest help sometimes comes from insulation, a tariff change, or landlord and supplier action, not from shorter showers. I think honest energy advice should name those structural factors, not pretend that turning off lights alone solves a draughty building or an unfair price.
Finally, I believe electricity saving works best as a household project, not a personal rule imposed on others. When everyone understands the bill, agrees on a few simple habits, and sees the result, saving becomes teamwork. When one person polices lights while others feel controlled, it becomes conflict. I would put the bill on the fridge, celebrate a lower month, and let children or housemates suggest one saving each. That shared ownership lasts longer than any single tip, because it turns a technical subject into a household habit. And habits, unlike gadgets, keep saving year after year without needing replacement.
On renters, my view is that energy advice too often assumes home ownership, which excludes millions of people who cannot insulate a wall or replace a boiler. I think renter-friendly advice deserves equal attention: portable measures, correct use of existing controls, and clear communication with landlords. A tenant who learns to program a thermostat, seals obvious draughts, and uses LED bulbs has done meaningful work, even without a renovation. Blaming renters for bills shaped by buildings they do not own is unfair, and advice that ignores their situation is incomplete.
I also believe shared households need shared agreements, not silent resentment. Electricity bills cause more housemate arguments than almost any other shared cost, because usage is invisible and habits differ. A short, friendly agreement at the start, plus a visible weekly meter check, solves most disputes before they grow. I would rather see housemates agree on a comfortable temperature and a laundry routine than see one person turn off lights behind others in frustration. Saving together feels like teamwork. Saving alone, against unwilling housemates, feels like conflict, and conflict rarely saves for long.
A final thought is that electricity saving should be measured in years, not weeks. A single cold month can make a bill look bad despite good habits, and a single mild month can make waste look harmless. I would judge a household’s progress over a year, comparing similar seasons, rather than reacting to one bill. That long view rewards insulation, efficient appliances, and steady habits, and it forgives the occasional high-use week. Energy saving is a household system, not a monthly test, and systems improve slowly, then suddenly, when a big fix finally pays off.
Another belief I hold is that small, visible wins motivate households more than abstract environmental arguments. When a family sees a bill fall after switching to LEDs, fixing draughts, and running full laundry loads, they believe in the next change. When they are only told to save energy for the planet, without any visible result, motivation fades quickly. I think energy advice should lead with money saved and comfort gained, because those are the results households can feel. Environmental benefit follows naturally from using less, but it rarely drives daily behaviour on its own.
I also think technology should be treated as a helper, not a replacement for habits. A smart thermostat that nobody programs, a smart plug that nobody schedules, and an energy app that nobody opens do not save anything. The most effective households I can imagine combine a few well-chosen tools with simple routines: heating on a schedule, lights off when rooms empty, machines run full, and a monthly glance at the bill. That combination is unglamorous, but it works in every home, with or without the latest gadgets, and it keeps working when a gadget breaks or a subscription ends.
Finally, I would encourage every household to start with one visible change this week, whether that is LED bulbs in the most-used rooms, a thermostat schedule that matches real life, or a weekly meter check. One change, done well and measured honestly, builds the confidence to make the next one. Households do not need to fix everything at once. They need to start somewhere real, see a result, and keep going, because steady small savings, repeated for years, become a genuinely lower bill.
Frequently Asked Questions
What uses the most electricity in a typical home?
Heating and cooling, water heating, and large appliances such as fridges, washing machines, and tumble dryers usually dominate usage. Lighting and small electronics use less by comparison, which is why fixing heating, hot water, and large appliances usually saves the most.
Do LED bulbs really save much money?
Yes, for frequently used lights. LEDs use a fraction of the power of old incandescent bulbs for the same brightness and last far longer. Replacing the most-used bulbs first gives the fastest payback, while rarely used bulbs can be replaced later.
Should I turn devices off at the wall or leave them on standby?
Turning devices fully off at the wall saves standby power, especially for entertainment systems and office setups left unused for hours. A switched power strip makes this easy for groups of devices. Modern phone chargers alone use very little standby power.
Is it cheaper to leave heating on all day or use a timer?
For most homes, heating only when rooms are occupied, using a timer or programmable thermostat, uses less energy than heating an empty home all day. The best schedule depends on insulation, building type, and daily routine, so test what keeps your home comfortable at lowest cost.
Does washing clothes in cold water really clean them?
For most everyday laundry, yes, especially with modern detergents designed for lower temperatures. Heavily soiled items, bedding, or towels may still benefit from warmer washes. Always follow garment care labels and detergent guidance.
How can I tell if a new appliance will save money?
Check its energy label for expected annual energy use and compare models of similar size. Add the purchase price to expected yearly running cost multiplied by expected years of use to estimate lifetime cost. A slightly more expensive efficient model can be cheaper overall.
