Simple ways to save energy at home

By Kat Sommers

Saving energy doesn't have to mean shelling out on a new boiler. A few quick wins make a big difference, whether you're a homeowner, renting your home or living with your parents.

Save energy in the kitchen

  • Only fill the kettle with what you need

  • Keep your fridge full and dust-free

  • Spend less time cooking by using your microwave

  • Wash up in a bowl of warm water

Saving energy around the home is as simple as making a cup of tea. But before you flip on that kettle, remember only filling it with the water you need could save you around £6 a year on your electricity bill.

Making life easier for your fridge can save some energy, too. Dust behind it once in a while to keep its coils clean and working efficiently. And as strange as it seems, keeping it full actually makes it work less hard, as the chilled food items help to keep the temperature down.

Buying an energy-efficient slow cooker is one way of cutting your energy bills. But your microwave is an unlikely energy saving hero too. By using less time to cook, it uses less energy too. This energy saving cake takes just two minutes to bake, though it's unlikely to bag you a spot on The Great British Bake Off any time soon.

Another simple change is washing up in a bowl of warm water. Not leaving the hot tap running can help you to cut your energy bills and your carbon impact, too.

Energy efficient laundry tips

  • Always try to fill your washing machine

  • Wash clothes at 30 degrees

  • Let clothes dry naturally

Cut down on the number of washes you do by waiting for a full load. Doing one less wash a week could save you £8 on your annual energy bill, not to mention a further £6 on metered water bills.

Setting your machine to wash at 30 degrees uses 57% less electricity than at higher temperatures. That'll earn you an annual saving of £8 a year.

And drying clothes is free, if you can hang them outside or on a clothes horse. Line-drying them instead of using a tumble dryer in the summer will pocket you £35 a year.

Using less energy in the bathroom

  • Spend one minute less in the shower

  • Turn down your hairdryer and hair straighteners

Spending one minute less in the shower each day could save an average household £10 on your energy bills (and around £17 on your water bill) each year. Swapping a normal shower head for a water-efficient one could knock another £30 off your water bill, and £17 off your energy every year, too.

As for drying yourself, a hairdryer and hair straighteners are some of the most energy-draining devices in your home. Embrace those curls and ditch them altogether, or use them on a cooler setting to save money.

Cut your bills with a smart meter

  • Get a smart meter installed for free

  • See how much energy you're using in pounds and pence

  • Work out which appliances use the most energy

  • Set a budget

  • Switch off appliances using a lot of energy

Knowledge is power. It's much easier to save money when you know what you’re spending it on in the first place.

A smart meter lets you keep an eye on your energy spending as you go. According to Smart Energy GB, 86% of smart meter households were able to make changes to their behaviour that resulted in saving money. You can get a smart meter installed for free if you're a Bulb member, and keep an eye on your usage using our app.

An In Home Display (IHD), which comes with your smart meter, shows you how much energy you’re using in pounds and pence. And it's in real time, so you can work out which appliances are the most expensive, and test the effects of all the energy saving tips on this page.

You can even set a daily, weekly or monthly energy budget to keep you on track (don't worry, you'll just hear a beep when your limit is reached. You won't lose your energy supply.)

Information like this lets you make smarter energy choices and notice patterns in your usage. It might remind you to turn off lights when you leave the room, for instance, and shave off £11 from your annual energy bill. Or not leave your telly and games consoles on standby mode. Believe it or not, but that little red dot on your appliances could be costing you up to £35 a year.

Low-cost ways to save money on your heating

  • Turn down your thermostat by one degree

  • Close curtains to stop heat escaping

  • Keep radiators clear and dust-free

  • Switch off radiators you're not using

  • Put tin foil behind radiators to reflect heat back into room

Heating our homes can be an expensive business. But we all want to stay warm and cosy, especially during the winter.

Of all the quick wins you can do right now, turning your thermostat down by one degree makes the biggest difference.

This tiny act not only saves you £55 a year, but it also avoids 300kg of CO2 from entering the atmosphere. That's the hard work of 150 trees.

Another way of saving money is making the most of the heating you already have. Draught proofing your windows and doors can save you around £25 a year. You could caulk around your window frames, block draughty door gaps with a towel, or just remember to close your curtains to keep the heat in. And get radiator savvy: if there's a room (or two) you don't spend much time in, then switch off the radiator, or turn it right down, and shut the door to save energy.

Radiators will also work much more efficiently if you dust between their 'fins' and keep them clear of any obstacles or furniture (or drying socks, for that matter).

You can even get your Blue Peter on: installing a panel of reflective foil behind your radiators could save you around £13 a year by reflecting heat back into the room. But a bog-standard sheet of kitchen tin foil does the job and is a low-cost alternative.
