Energy efficiency advice
One of the best ways to lower the cost of your gas and electricity bills is to reduce how much energy you use at home.
Take a look at some of our simple, affordable tips and advice to help you lower the amount of energy you use, particularly when it’s colder, and potentially reduce your bills.
Switch off standby
Switch appliances off when you’re not using them. Appliances like your TV, stereo and computer continue to use electricity when they’re in standby mode. Turning them completely off when they're not being used could save you as much as £65 a year.
Turn off your lights
By switching off lights when you're not using them, you can save around £25 a year on your energy bills.
Switch to LEDs
Switch to LED bulbs and save more on your lighting. For the average household it would cost £145 to switch every bulb, but could save around £30 each and every year on bills.
Be smart in the kitchen
Your kitchen is filled with simple ways to save. Here are just a few examples:
Reducing you washing machine use by one run per week and washing 30°C instead of at a higher temperature, could save you around £34 a year.
Only use your dishwasher when it's full – this'll reduce the amount of water you use. Plus, lowering your dishwasher use by one run per week for a year could save you an extra £17.
Only fill your kettle with the amount of water you need – you don’t need a full one for just one cuppa. This will save you around £13 in energy bills a year. Similarly, when cooking, use the correct size of pans to save energy.
Fit an aerator onto your kitchen tap to reduce the amount of hot water coming out. It's a small, easy to install, cheap gadget with tiny holes that can be attached to the taps – and it could save as much as £30 a year, according to the Energy Savings Trust.
Reduce your shower time by one minute, and add a water efficient showerhead. This could save you £4 a year off your energy bill for every person in your household.
Taking a shower costs less than a bath. You could be saving £20 a year by swapping one bath with a four-minute shower each week.
Draught-proofing is one of the cheapest and most effective ways to save energy and money. Based on a typical gas-fuelled semi-detached property, you could save £60 a year by blocking draughts around windows and doors.
Think of your thermostat
Heating controls help you stay on top of how much energy you're using. By turning down your room thermostat by just one degree, you could save £145 a year.
Keep your hot water hot
Fitting a hot water cylinder with an insulating jacket will save you some money. It should be at least 80mm thick; if it isn’t, consider buying a new one. Upgrading from 25mm to 80mm thick, using a British Standard jacket, could save you around £70 a year.
By investing in new windows, you can keep warmer and save energy. Installing A-rated double glazing in an entirely single-glazed, semi-detached gas-heated property could save you £195 per year and 330kg of carbon dioxide. If you install A++ rated double glazed windows to replace single glazing, the savings could be up to £235 per year and 405kg of carbon dioxide.
Install loft insulation
A quarter of heat is lost through the roof in an uninsulated home. Installing the correct level of insulation for your loft, attic or flat roof can help reduce heat loss and lower your energy bills.
Get smart with your meter readings
Installing a smart meter is another great way to save energy. By making it easier to understand your energy usage, it helps you take steps to use less. If we all used a smart meter, the CO2 savings Britain could make would be equivalent to the savings made by around 70 million trees*.
