How to Cut Electricity Use at Home: 2026 Guide

To cut electricity use at home, focus on the appliances that use the most power, switch off devices left on standby, swap to LED bulbs and shift heavy use to cheaper times if you have a smart tariff. These steps target the parts of your bill you can actually change, rather than the standing charge you can’t.

This matters more from 1 July 2026, when Ofgem’s energy price cap rises by 13% to around £1,862 a year for a typical dual-fuel household paying by Direct Debit. The cap limits unit rates and the standing charge for a typical user, not your total bill, so the less electricity you use, the less you pay.

• Wet appliances (washing machine, tumble dryer, dishwasher) and fridges/freezers are usually the biggest electricity users in a UK home.
• Turning appliances off standby can save around £45 a year, and line-drying instead of tumble-drying can save up to £50 a year (Energy Saving Trust, GB figures).
• From 1 July 2026, the average electricity unit rate rises to around 26.11p per kWh under Ofgem’s price cap.
• A smart time-of-use tariff lets you run appliances when electricity is cheaper, but the saving depends on shifting usage off-peak.

Which appliances use the most electricity at home?

The biggest electricity users in most UK homes are wet appliances such as washing machines, tumble dryers and dishwashers, followed by fridges and freezers, then electronics, lighting and cooking. According to the Energy Saving Trust, washing machines, dishwashers and tumble dryers account for around 14% of a typical energy bill, because heating water and air takes a lot of power.

Fridges and freezers add around another 13% because they run continuously, while lighting makes up around 5% of an average home’s total energy bill. Targeting these areas first gives the largest reductions for the least effort.

Knowing where your power goes helps you prioritise. If you want a fuller breakdown of efficiency measures, our guide to energy efficiency tips covers the main upgrades worth making.

How to cut electricity use in the laundry and kitchen

The fastest way to cut electricity use in the laundry is to wash at 30°C and use the tumble dryer less, since drying is one of the most expensive everyday tasks. The Energy Saving Trust estimates that washing at 30°C and doing one fewer wash a week saves around £27 a year in GB, and avoiding the tumble dryer by drying clothes on a rack can save around £50 a year.

Tumble dryers are the clearest example of why appliance choice matters. A standard condenser dryer typically costs noticeably more to run each year than a more efficient heat-pump model, so the type of dryer you choose can make a meaningful difference to running costs; check the current running-cost estimates for the specific model you’re considering. If you dry clothes outside in warmer months or on an airer indoors, you avoid that cost entirely.

In the kitchen, only run the dishwasher when it is full and use the eco setting, which uses less water and heat. Avoid overfilling the kettle, which the Energy Saving Trust links to around £10 a year in GB. Defrosting frozen food in the fridge overnight rather than the microwave costs nothing in extra electricity.

• Wash at 30°C and use the eco cycle.
• Dry on a rack or line instead of the tumble dryer where possible.
• Run the dishwasher only when full, on eco mode.
• Boil only the water you need in the kettle.

Does turning appliances off at the wall actually save money?

Yes, turning appliances off standby can save a typical household around £45 a year in GB, according to the Energy Saving Trust. Standby power is the electricity devices draw while switched off but still plugged in, often shown by a glowing light or a clock display.

The biggest standby culprits are TVs, set-top boxes, games consoles, monitors, printers and chargers left plugged in. A standby saver plug or a switched extension lead lets you cut several devices at once with one switch, which is more practical than reaching behind furniture each night.

Some items should stay on, including fridges, freezers, routers you rely on, and anything running a smart-home or alarm function. Be sensible about what you switch off, but most living-room and home-office electronics gain nothing from being left on standby overnight.

Why is my energy usage so high when I’m not at home?

High electricity use when nobody is home usually comes from appliances that run continuously or on a cycle, not from people actively using power. Fridges, freezers, routers, smart devices, immersion heaters and anything left on standby all keep drawing electricity around the clock.

If your usage looks unexpectedly high, check the meter on the wall rather than relying only on the in-home display, which can occasionally drift out of sync. A sudden jump in baseline use can point to an immersion heater or electric heater cutting in, a failing fridge or freezer, or a setting changed after a power cut.

A smart meter and its half-hourly readings make it easier to spot what is running overnight. Looking at your lowest usage period, when most things are off, shows your home’s baseline load and where to investigate.

How much can LED lighting and smaller electronics save?

Switching all halogen bulbs to LEDs costs around £180 but can save about £45 a year in GB, according to the Energy Saving Trust, and LEDs last far longer. Simply switching lights off when you leave a room adds around £8 a year in savings.

Electronics size matters too. A 60-inch F-rated TV costs around £45 a year to run in GB, while a 40-inch F-rated model costs around £20 a year. If you work from home, a laptop uses far less power than a desktop and monitor, and setting devices to sleep when idle reduces background draw.

For lighting reception rooms and bedrooms, lower-wattage LED lamps and task lighting let you avoid lighting a whole room when you only need a small area lit. These are low-cost changes that build up over a year. Our overview of the role of technology in reducing electricity costs explains how smart controls fit in.

Can smart tariffs cut your electricity bill?

Smart time-of-use tariffs can cut your electricity bill if you can move heavy use to cheaper off-peak periods, but they only help if you actually shift when you use power. A time-of-use tariff charges different unit rates at different times of day, rewarding you for running appliances when wholesale electricity is cheaper.

These tariffs suit households with an electric vehicle, a heat pump, a home battery, or the flexibility to run the washing machine and dishwasher overnight. Some EV-focused tariffs offer a cheap overnight window of around 7p per kWh for charging, well below the price-capped daytime rate. Others give several cheaper windows across the day for heat pumps, with a more expensive evening peak.

The trade-off is that peak-time electricity on these tariffs can cost more than the standard capped rate. If you cannot shift much usage away from the evening peak, a time-of-use tariff may not save money. A smart meter is needed for most of these tariffs, and you should never schedule appliances to run while you are asleep or out, because of fire risk.

If you charge an electric car, our guide on the energy price cap and EV charging costs shows how off-peak windows change the maths.

Do solar panels and timers help reduce electricity use?

Solar panels reduce the electricity you buy from the grid by generating your own power during daylight hours, and you can earn money for surplus exported under the Smart Export Guarantee. The actual saving depends on your roof, how much electricity you use during the day, and whether you add a battery to store generation for the evening.

Solar works best when you use power while the sun is up, so running the dishwasher, washing machine or charging a battery during the day captures more of the free generation. A battery lets you store daytime solar for use in the evening peak, increasing the share of your own electricity you use. You can read more in our guide to solar panels and sustainable energy.

Plug-in timers and smart plugs are cheap and useful for scheduling appliances, but on a standard single-rate tariff they save little, because the unit rate is the same all day. Timers pay off mainly when paired with a time-of-use tariff, so you run loads during the cheaper window. They will not reduce a fridge or freezer’s running cost, which is fixed by how the appliance runs.

Is help available with electricity costs?

Yes, eligible low-income households can receive £150 off their winter electricity bill through the Warm Home Discount scheme, which the government expanded for 2025/2026. The discount is usually applied automatically as a credit to your electricity account, and you do not normally need to apply if you qualify.

Eligibility centres on receiving certain means-tested benefits, and the scheme is run with energy suppliers under rules set by Ofgem and the Department for Energy Security and Net Zero. Citizens Advice and the Energy Saving Trust both publish guidance on eligibility and other support, including help with insulation through the Great British Insulation Scheme.

Beyond bill support, an Energy Performance Certificate shows where your home loses energy, which can guide insulation and heating improvements that lower electricity use over time. Check with your supplier whether you qualify for the Warm Home Discount before each winter, as the criteria and timing can change.
