Monitor your energy use

You have the power to both save the planet and money, simply by cutting back on your energy consumption

Every day we rely on energy to heat our homes, chill our food, clean our clothes and charge our mobiles and tech. We depend on electricity and gas to go about our daily lives, but just because it’s convenient, this doesn’t mean we should be frivolous with how much we use.

Get smart

Stopping to think about your energy usage is the first step to reducing the amount that is wasted. A smart meter will show you how much energy you're using, what it's costing and help you to track down your energy-guzzling gadgets. Find out how much electricity you use

Get saving

Little changes that require minimal effort quickly add up – especially if you do them daily. What’s more, you’ll not only help to save the environment, you could also save money.

Simple tips for easy wins:

  1. Turn down the heating
    Set your room thermostat to 18°C instead of 19°C and that small difference will reduce your carbon footprint Carbon footprintThe amount of carbon dioxide (or the equivalent in other greenhouse gases) released into the atmosphere as a result of the activities of an individual or organisation – one degree can save 310kg of CO2 Carbon dioxide (CO2)A gas that occurs naturally in the Earth’s atmosphere and is also the main greenhouse gas produced by human activities and £60 a year for a typical household.
  2. Wash clothes at 20°C
    Which? research has found that switching from a 40°C to a 20°C wash would save the same amount of CO2 Carbon dioxide (CO2)A gas that occurs naturally in the Earth’s atmosphere and is also the main greenhouse gas produced by human activities taking over 400,000 cars off the road. Even opting for a 30°C wash makes a 37% saving in energy. Buying a washing machine with the right capacity for your needs means you’ll put on fewer loads.
  3. Keep your kettle clean
    A kettle that’s full of limescale is going to use more energy to boil water, so descale it regularly. Remember, too, when making a cuppa to only boil the amount of water you need.
  4. Wise up to washing up
    Even the least water-efficient dishwasher still only uses half the amount of water compared to washing by hand. Learn how to load it properly, too.
  5. Buy efficient appliances
    If it’s time to buy a new television, tumble dryer or something else for your home, choose an item that's energy efficient and more environmentally friendly to run. Look for the new energy labels on products and for further peace of mind, pick a Which? Eco Buy.
Working from home


While many people who have found themselves sitting at a study desk or kitchen table during lockdown can list a range of benefits as a result of working from home, pandemic restrictions mean households have been using more energy for heating, lighting and running appliances. To counterbalance this, why not…


  • Turn down the lights. Turning your computer screen brightness down from 100% to 70% could reduce energy usage by 20%.
  • Dry washing outdoors. Use any outside space (even a balcony) to hang out clothes instead of tumble drying. Because you're at home, you can keep an eye on the weather and any ominous clouds.
  • Don’t leave tech on standby. At the end of the day, turn off laptops, computers and monitors. Standby mode still uses a small amount of electricity.
