Energy bills are one of those household costs that can feel completely out of your control.
You switch on the heating because you’re cold. You cook dinner because everyone needs to eat. You put the washing machine on because the laundry basket is overflowing. None of those things feel extravagant, yet the monthly bill can still come as an unpleasant surprise.
The good news is that cutting your energy costs doesn’t have to mean living in a freezing house or sitting in the dark every evening. In fact, many of the best money-saving habits are barely noticeable once they become part of your routine.
Here are 25 practical ways to reduce your energy bills while keeping your home warm, comfortable and enjoyable to live in.
1. Turn your thermostat down by just one degree
You probably won’t notice the difference, but your heating system will.
Reducing your thermostat by just 1°C can lower your heating costs over the course of a year, while your home should still feel perfectly comfortable.
2. Only heat the rooms you’re using
If your home has thermostatic radiator valves, use them to lower the temperature in rooms you rarely use.
There’s little point heating a spare bedroom all day if nobody is in it.
3. Close your curtains as soon as it gets dark
Windows lose heat surprisingly quickly.
Closing curtains before the evening gets colder helps keep warmth inside your home, especially if you have thick or thermal-lined curtains.
4. Stop draughts
You don’t need an expensive renovation to reduce heat loss.
Simple draught excluders, sealing strips around doors and windows or even a rolled-up towel at the bottom of a door can make a noticeable difference.
5. Bleed your radiators
If your radiators are cold at the top but warm at the bottom, trapped air could be stopping them from working efficiently.
Bleeding them takes only a few minutes and helps your heating work more effectively.
6. Don’t block your radiators
Large sofas, curtains or furniture placed directly in front of radiators stop warm air circulating properly.
Moving furniture just a little can help heat spread around the room more effectively.
7. Wash clothes at lower temperatures
Modern detergents work well at 30°C for most everyday washing.
Lower temperatures use less energy while still getting clothes clean.
8. Wait until you have a full load
Whether it’s the washing machine or dishwasher, running a full load usually uses less energy than running several smaller cycles.
Just avoid overloading, as that can reduce cleaning performance.
9. Air dry clothes whenever possible
Tumble dryers are convenient but can be one of the more energy-hungry appliances in many homes.
Whenever the weather allows, use a washing line or indoor airer instead.
10. Use your dishwasher efficiently
It may seem surprising, but a full dishwasher often uses less water and energy than washing the same number of dishes by hand.
Eco programmes may take longer, but they usually use less energy because they heat the water more gradually.
11. Boil only the water you need
If you’re making one cup of tea, only fill the kettle with enough water for one cup.
It’s a tiny habit, but repeated every day it can save both water and electricity.
12. Put lids on saucepans
Cooking with lids keeps heat inside the pan, meaning food cooks more quickly and uses less energy.
It’s one of the simplest kitchen habits you can adopt.
13. Batch cook meals
Using the oven once to prepare several meals is often more efficient than heating it every evening.
Batch cooking also saves time and can help reduce your grocery bill.
14. Make the most of residual oven heat
Many dishes continue cooking for a few minutes after the oven is switched off.
If you’re nearly finished cooking, turning the oven off slightly early can make use of the remaining heat.
15. Defrost your freezer regularly
Ice build-up makes freezers work harder.
Keeping your freezer frost-free helps it run more efficiently and gives you more storage space too.
16. Check your fridge temperature
Your fridge doesn’t need to be set to the coldest possible setting.
Keeping it at the recommended temperature helps preserve food without wasting unnecessary energy.
17. Keep your freezer full
A well-stocked freezer holds its temperature better than an almost empty one.
If you don’t have much food inside, even bottles of water can help fill empty space.
18. Switch appliances off instead of leaving them on standby
Many modern appliances continue using small amounts of electricity while on standby.
Turning them off completely when they’re not needed can help reduce unnecessary energy use.
19. Use LED light bulbs
If you still have older bulbs, replacing them with LED versions is one of the easiest long-term energy-saving upgrades you can make.
They use much less electricity and generally last far longer.
20. Take shorter showers
You don’t need to rush, but shaving just a couple of minutes off your daily shower can reduce both water and heating costs over time.
21. Service your boiler
A well-maintained boiler is generally more efficient and less likely to develop expensive problems.
Annual servicing also helps identify small issues before they become larger repairs.
22. Compare your energy tariff
Loyalty doesn’t always pay when it comes to energy suppliers.
It’s worth checking from time to time whether you’re still on the most suitable tariff for your household.
23. Make use of smart meters or energy monitors
Seeing how much energy you’re using can make it easier to spot waste and understand which habits have the biggest impact.
Even small behavioural changes can add up over a year.
24. Wear an extra layer before reaching for the thermostat
A cosy jumper or pair of warm socks can often make enough difference that you delay turning the heating up.
It isn’t about sitting shivering—it’s about making yourself comfortable in a different way first.
25. Focus on habits, not perfection
Perhaps the biggest energy-saving tip of all is not trying to do everything at once.
Choose two or three habits that feel easy to stick with.
Once they become routine, add another.
Small changes repeated every day often save far more money than dramatic changes that only last a week.
Which tips save the most money?
If you only choose a handful, these usually offer the biggest long-term impact:
- Lowering your thermostat slightly.
- Preventing draughts.
- Washing clothes at 30°C.
- Air drying laundry where possible.
- Using LED bulbs.
- Switching off standby appliances.
- Comparing your energy tariff regularly.
- Using appliances with full loads.
Frequently Asked Questions
Will lowering my thermostat make my house feel cold?
Not necessarily. Many people don’t notice a reduction of just 1°C, especially if they wear normal indoor clothing and reduce draughts at the same time.
Is it cheaper to leave the heating on all day?
In most cases, no. Heating your home only when you need it is generally more efficient than keeping it on continuously, although the best approach depends on your heating system and insulation.
Do LED bulbs really save money?
Yes. They use significantly less electricity than older incandescent or halogen bulbs and usually last much longer, making them a worthwhile investment over time.
Is it worth switching energy suppliers?
It can be. Comparing tariffs every so often may help you find a deal that’s better suited to your household’s energy use, although the best option depends on current market conditions.
Final thoughts
Reducing your energy bills doesn’t have to mean giving up comfort.
Most of the savings come from small, sensible habits that don’t make your home feel any less welcoming. Closing the curtains at night, washing clothes at a lower temperature, stopping draughts or filling the dishwasher before switching it on are all changes that quickly become second nature.
