According to the energy market regulator Ofgem, the average UK dual fuel variable tariff as of April 2018 is £94.83 per month, or £1,138 a year.
We all need to look at ways to cut carbon emissions and energy use and, in a very real sense, saving energy has come to equal saving a lot of money too.
Whether you are already serious about energy conservation or just beginning to think it might be a good idea, the ideas here could form the basis of your ‘must-do’ list. They are the easiest and most common-sense steps to take to reduce energy consumption in the home, and can reduce bills by as much as 10 to 20 per cent at no cost other than a small change in habits.
This doesn’t mean you have to sit shivering wrapped in a blanket in a dimly-lit room! Applying these simple energy saving tips can deliver long-term financial rewards and make your home more comfortable too. If you dig out last year’s energy bills you can compare energy use and see how well you are doing. Then as you start to make some real savings you can invest the money saved into energy efficient products and measures such as increased insulation to reduce energy use and costs even further.
Turning the thermostat down by just 1 degree could cut your heating bills by 10%. The recommended temperature range is between 18-21°C and by dressing appropriately for the weather you may not even notice the difference. If you are out at work all day set the heating to turn off 30 minutes before you leave home and come on again 30 minutes before you are due to return. Turn the heating off at night and set it to come on again 30 minutes before you get up. Only heat the rooms you need – close the windows and doors of unused rooms – and if you’re going away in winter, leave the thermostat on a low setting just enough to provide protection from freezing.
Keep the draughts out
Close your curtains in all rooms at dusk to reduce heat escaping through the windows and save between £10 and £15 a year on your heating bills. Take care not to drape curtains over radiators – shorten them or tuck them up onto the windowsill if necessary. Make draught excluder ‘sausages’ by rolling up old blankets to stop draughts under external doors. A ¼ inch wide gap under your front door will waste about the same amount of heat as if you had a 2″ square hole in the wall!
Turn off the lights when you are leaving a room. Use low energy LED bulbs. Adjust your curtains or blinds to let in as much natural light as possible during the day.
Is your water too hot? Your cylinder thermostat doesn’t need to be set higher than 60°C/140°F. Every 5.5 degrees C. reduction can save up to 13 per cent on your water heating costs. Always put the plug in your basin or sink so you don’t run the water continuously when washing dishes by hand, shaving, or washing your face and hands.
An average bath requires 30-50 gallons of water. The average shower of four minutes uses 20 gallons of water (power showers often use more water than a bath in less than 5 minutes). Monitor the amount of time you spend in a shower and challenge yourself to reduce that time. Visit Save Water Save Money for water efficient shower heads, shower timers and Flow Savers.
In just one day, a dripping hot water tap can waste several gallons of water – make sure taps are turned off and replace worn washers. The Energy Saving Trust have a Water Energy Calculator, and Save Water Save Money have inexpensive tap aerators to reduce water use.
Always wash a full load – if you can’t, use the half-load or economy programme. 90% of the total energy used by a typical washing machine is for heating the water – only 10% is used to power the motor. So use a low temperature or cold programme – with modern washing detergents this will be just as effective and can noticably reduce the electricity consumption.
An average tumble dryer cycle uses just over 4kWh of energy and produces around 1.8kg CO2. Line dry clothes whenever possible, or dry indoors on a rack or hangers – don’t put them over a radiator as this will stop the heat from reaching the rest of the room. Or put a clothes rail in an unheated room, open the window slightly to allow damp to escape, and keep the door closed to prevent heat being drawn into that room. Never put really wet clothes into the tumble dryer. Spin-dry and separate them out before putting into the dryer- they will dry much faster. Dry towels and heavier cottons in a separate load from lighter-weight clothes. Be careful not to overdry. Clean the lint filter every time the machine is used. If you have a condensing dryer keep the condenser unit clean and if there is a water tray ensure it’s emptied after every load.
Fridges and freezers
Don’t leave the fridge or freezer door open for longer than necessary as cold air will escape – get your contents organized so you can find what you want right away. Avoid putting hot or warm food straight into the fridge or freezer; allow it to cool down first. Make sure there is room for air to circulate behind your fridge and keep the condenser coils on the back free of dust. Try not to place refrigeration equipment near heaters or the cooker – the cooler your refrigerator’s immediate environment, the less energy it will use.
Defrost the freezer regularly to keep it running efficiently. If it tends to frost up quickly, check the seal by closing the door/lid onto a piece of paper – if you can easily slide the paper out it might be time to change the seal. If possible, keep the freezer in a cool room or garage.
Modern dishwashers use half the energy and one-sixth of the water compared to washing the same amount of dishes by hand. Always wash a full load or use the half-load or economy programme. Use a cool setting – 80% of the energy used by a dishwasher goes to heating the water. Rinse dishes off in cold water before putting them into the dishwasher.
Heat only the amount of water you really need – jug type kettles can boil less water as they have smaller elements. In hard water areas, you need to remove limescale to keep your kettle working efficiently for longer. Every six months or so, soak the element overnight in vinegar.
Microwave cookers are a fast and cheap way to cook smaller quantities or to reheat food, using between 70% and 90% less electricity than an electric oven. Use a toaster rather than the grill to make toast.
Don’t peek while using your oven; you lose about 20 per cent of the heat every time you open the door. Choose the right sized pan for the food and cooker – the base should just cover an electric cooking ring. With gas the flames should only heat the bottom of the pan and not lick up the sides. Keep lids on when cooking and don’t use more water than you need because it not only wastes energy, it can spoil the food too! Pressure cookers and food steamers save energy.
Energy saving appliances
If you are replacing household electrical appliances look out for the ‘Energy Saving Recommended’ logo. All new electrical appliances display a label explaining how much energy the appliance uses. Energy efficient products don’t always cost more than inefficient models and will use less energy over their lifetime so will be cheaper to run. An appliance graded A (most efficient) uses less than half the energy of similar models graded G (least efficient) and could save you up to £37 a year.
Could you be paying too much for gas and electricity?
You could save hundreds of pounds a year by switching energy suppliers, especially if you’ve never switched before. So if you haven’t compared prices recently it’s worth checking at the online comparison sites. You don’t necessarily have to switch your supplier to make savings – if you pay your energy bills by cheque or cash you’ll get a discount for paying by direct debit instead or switching to an online account.
One of the simplest ways to cut your carbon emissions is to sign up to a green tariff so that all or some of your home’s electricity will come from renewable sources such as wind power.
