Electricity slips away in small amounts, all day long. The telly on standby, the tumble dryer, the old bulbs, the kettle boiled twice. None of it feels like much. Added up over a year, it's real money. Here's how to plug the drains.

What uses the most electricity, and how do I cut it?

The big everyday electricity users are anything that heats (kettle, tumble dryer, electric shower, oven) plus always-on standby devices. Switch appliances off at the wall (the Energy Saving Trust estimates ~£65 a year from standby alone), swap remaining bulbs for LEDs, wash clothes at 30°C and run full loads, and only boil the water you need. If you have a smart meter and an off-peak tariff, shift heavy use to cheaper hours.

Key takeaways

•     “Phantom” standby power runs up your bill quietly, switching off at the wall can save ~£65/year (Energy Saving Trust).

•     LED bulbs use far less electricity than old incandescent or halogen bulbs and last for years.

•     Most of a washing machine's energy goes on heating water. 30°C washes cut that sharply.

•     Run washing machines and dishwashers with full loads, not half-empty.

•     Tumble dryers are heavy users, air-dry when you can.

•     A smart meter plus an off-peak tariff lets you shift heavy use to cheaper hours.

Electricity is the sneaky bill. Unlike heating, there's rarely one big obvious culprit, it's dozens of small draws happening at once. The upside is that lots of small fixes stack up fast, and almost none of them change how you actually live.

1. Kill the standby drain

“Phantom load”, the power devices use while switched off but still plugged in, is the classic invisible cost. TVs, games consoles, set-top boxes, chargers and speakers all sip electricity around the clock. The Energy Saving Trust estimates that switching appliances off at the wall rather than leaving them on standby saves a typical home around £65 a year.

Make switching off effortless

•     Use a standby-saver or a plug strip with an on/off switch so you can kill several devices at once.

•     Unplug chargers when they're not charging, they draw power just sitting there.

•     Switch off at the wall at bedtime, the TV, console and speaker cluster is a good place to start.

2. Switch to LED lighting

If you still have any old incandescent or halogen bulbs, this is one of the easiest wins going. LED bulbs use far less electricity, roughly 75–90% less than old incandescents, and last many times longer, so you replace them far less often. They've become cheap, and the payback is usually well under a year.

Don't wait for old bulbs to blow. Swapping them now starts saving immediately, especially in the rooms where the lights are on longest. And the simplest habit of all still counts: turn lights off when you leave a room.

3. Do your laundry the smart way

Your washing machine's biggest energy cost isn't spinning the drum, it's heating the water. That's why a few laundry habits make a real difference:

Wash at 30°C

Modern detergents work well at low temperatures. Dropping from 40°C to 30°C cuts the energy used to heat the water, and most everyday loads come out just as clean.

Run full loads

A half-empty machine uses almost as much energy as a full one. Wait for a full load, or use a half-load/eco setting if you can't.

Air-dry instead of tumble-drying

Tumble dryers are among the hungriest appliances in the house. Drying on a rack or line whenever you can avoids that cost entirely.

4. Kitchen and appliance habits

The kitchen is full of things that heat, and heating is where electricity gets expensive. A few tweaks:

•     Only boil the water you need. Kettles are power-hungry; don't fill it for one cup.

•     Run the dishwasher full, and use its eco mode, it heats less water.

•     Use lids on pans. Food heats faster, using less energy.

•     Microwave small portions, far more efficient than the oven for small jobs.

•     Keep the fridge seal clean. A good seal means the fridge works less hard.

•     Choose efficient appliances, check energy ratings when you replace one.

5. Smart meters and off-peak tariffs

A smart meter doesn't cut your usage by itself, but it shows you where your electricity goes, which makes it much easier to change habits. The real saving comes if you pair it with a time-of-use (off-peak) tariff: electricity is cheaper at certain hours, so running the dishwasher, washing machine or an EV charger overnight can cost noticeably less.

Worth checking your tariff. Energy prices and tariffs change, so it's worth reviewing whether your current deal suits how you actually use electricity. Impartial help is available from Citizens Advice and the government-backed guidance on choosing an energy tariff. Smart Cover isn't an energy supplier, so we can't switch your tariff, but the habits in this guide help whichever deal you're on.

Savings at a glance

Indicative estimates from the Energy Saving Trust for a typical home. Actual savings vary with your usage, appliances and current electricity prices.

• Switch off standby: around £65/year, effort very low

• Turn lights off / switch to LED: ~£25/year from lights off, more from LEDs, effort low

• Wash at 30°C, full loads: adds up over a year, effort very low

•  Air-dry instead of tumble-dry: meaningful, dryers are heavy users, effort low

•  Off-peak tariff (if it suits you): depends on usage and tariff, effort medium

Efficient appliances cost less to run

An appliance that's maintained and working properly uses less electricity, and won't hit you with a surprise repair bill. Smart Cover's appliance and multi-appliance cover keeps your washing machine, fridge, cooker and more protected, with a repair arranged when you need it.
