10 tips for saving energy in your home this winter (2024)

Here are some quick and easy actions you can take to reduce your energy usage and therefore your bills:

1. Adjust your combi boiler flow temperature to60°C or below

Turning down the flow temperature on yourcombi boiler to 60°C or below can knock £££s off your heating bill each year and reduce energy waste from your home.

If 10 million households turned down the flow temperature on theircombi boilers to 60°C or below it could wipe £1 billion off UK energy bills and save 1.7 million tonnes of carbon emissions – the equivalent of nearly six million transatlantic flights.

2. Heat the right places at the right times

Make sure your radiators aren’t covered or blocked by furniture, so the heat can get into the room. Fitting radiator reflector panels will also help to reflect heat back into the room.

If possible, turning down the radiators in rooms that you aren’t using will also help to conserve energy and make further savings.

Set the timer on your central heating, to make sure your property is being heated only when needed.

3. Be mindful of hot water use

Reducing your shower time to four minutes could save a typical household around £95 a year on energy bills.

If you tend to have baths, swapping one bath a week with a four-minute shower could save £20 a year.

If you have a hot water cylinder, make sure it’s insulated. British Standard tank jackets usually measure at least 75mm thick, but the best insulation is achieved with 80mm thickness and can save up to £50 a year.

4. Don’t boil more water than you need

Around 4% of the typical energy bill is spent on powering kitchen appliances, including the kettle, hob and oven.

By only boiling as much water as you need, rather than overfilling the kettle, you could save around £13 a year on your electricity bill.

Max La Manna, low-waste chef and host ofThe Clean Energy Revolution podcast season 2, also recommends this energy-saving tip to cook pasta while only using the hob for 2 minutes: “Cook (the pasta) for 2 minutes in the boiling water. Turn the hob off, cover with a lid, set a timer for 10 minutes and… 10 minutes later, the pasta’s cooked and it works like a charm every single time.”

5. Unplug your ‘Vampire Devices’

So named because they drain power when left plugged in or on standby mode, switching off vampire devices could typically save £60-£70 a year according to the Energy Saving Trust.

Vampire devices that drain the most electricity include:

• Smart speakers and smart home devices
• Set top boxes and recorders
• TVs
• Microwaves
• Phones, tablets, computers and laptops left on charge
  

6. Think about how you’re lighting your home

This one may seem obvious, butlighting makes up 11% of the average UK household electricity consumption so it’s definitely worth keeping in mind. Turning off lights when you’re not using them, or when you leave a room, could save around £25 a year on your annual energy bills.

Replacing the bulbs in your home with LED lights can lower your electricity bill even more and also reduce your home’s carbon dioxide emissions by up to 50kg a year – equivalent to driving your car around 145 miles.

7. Consider when – and how – you use your washing machine

You can save around £34 a year on your energy bills by following the steps below:

• Run your washing machine on a 30-degree cycle.
• Reduce your washing machine use by one run per week for a year.
• Always use your washing machine on a full load or use a half-load programme for smaller loads.
  

8. Run the dishwasher one less time each week

Reducing your dishwasher use by one run per week could save around £17 a year. Try to only run the dishwasher once it’s full – this will also reduce the amount of water you use.

9. Use tumble dryers sparingly

Avoid using the tumble dryer for your clothes unless it’s absolutely necessary and save up to £70 a year. When the weather doesn’t allow for drying clothes outside, hang them on racks inside your home where possible.

10. Draught-proof windows and doors

Older homes lose heat through draughts around doors and windows, gaps around the floor or through the chimney. Professional draught-proofing of windows and doors, and blocking cracks in floors and skirting boards, can save around £125 a year on heating bills.

Other simple draft proofing measures – such as closing curtains, your letterbox and keyhole covers, and chimney balloons – can also help keep the warmth in and cold out.
