General energy saving tips and advice
SAVING: €416 a year
3 (kWh) x 2 (hours) x €0.48.19 (unit price) = €2.89 (to fully heat tank)
x 6 (times a week) x 4 (weeks in a month) = €69.39 x 12 = €832.68 a year
VS
x 3 (times a week) x 4 (weeks in a month) = €34.68 x 12 = €416.16 a year
Saving: €832.68 - €416.16 = €416.52 a year
SAVING: €83* a year
9.5 (kWh) x €0.4819 (unit price) = €4.58 per hour / 60 x 7 = €0.53 (7 min shower)
VS
€4.58 / 60 x 10 = €0.76 (10 min shower)
Saving: €0.23 x 30 = €6.90 a month x 12 = €82.80 a year
*Prices based on electric shower energy usage rates.
SAVING: €104 a year
3kWh x €0.4819 (unit price) = €1.45 an hour / 60 x 45 = €1.08 per 45-minute load approx.
Estimated average 4 loads per week:
€1.08 x 4 = €4.32 a week x 4 = €17.28 a month
Reduced to 2 loads per week:
€1.08 x 2 = €2.16 a week x 4 = €8.64 a month
Saving: €8.64 a month x 12 = €103.68 a year
SAVING: €286 a year
Please note calculations are an estimated average and will vary based on size of house, time of year, number of people in house etc.
Traditional bulbs: 75W per hour x 10 (lightbulbs) x 2.5 (hours per day) = 1875W = 1.875kWh x €0.4819 (unit price) = €0.90 per day x 365 = €328.50 per year
LED bulbs: 9W per hour x 10 (lightbulbs) x 2.5 (hours per day) = 225W = 0.225kWh x €0.4819 = €0.11 per day x 365 = €40.15 per year
10 LED lightbulbs = €20 (average estimated cost)
Saving: €328.50 – €40.15 = €288.35 – €20 (cost of bulbs) = €268.35 a year
SAVING: €186 a year
Average annual gas bill: €1865
Saving: €1865 / 10 = €186.50 a year
SAVING: €73 a year
2.5kWh x €0.4819 = €1.20 per hour / 60 = €0.02 per minute (boil 1 cup) x 5 (times a day) = €0.10 per day x 365 = €36.50 a year
VS
€0.02 x 3 minutes (boil full kettle) x 5 (times a day) = €0.30 per day x 365 = €109.50 a year
Saving: €109.50 – €36.50 = €73 a year

Kitchen: cooking & food storage tips
Cooking
Cooking is one of the most energy-intensive activities in the home, here are some simple ways you can save energy in the kitchen.
1. Choose the right pots and pans
- Flat-bottomed pots and pans allow heat to disperse more evenly
- Cookware with copper on the bottom heat up faster than other materials
- Putting lids on your pots and pans speeds up cooking time
- Match the size of your pan to the hob you’re using to avoid wasting energy
- Glass or ceramic dishes are most efficient when cooking in the oven, so you can cook at a lower temperature or for a shorter time
2. Cook extra
- Batch cook different meals in the oven at the same time
- Reheating food (particularly using a microwave) is much more energy efficient than starting from scratch
- Slow cookers and air fryers are more energy-efficient alternatives to the oven if you haven’t had time to batch cook
- But don’t boil extra! A very common tip but a good habit to get into – only boiling the amount of water you need can save a lot of energy over time
- Avoid opening your oven door too often during cooking – you can lose up to 20% of the oven’s heat doing this so it has to work harder to maintain its temperature
- Make use of the heat that has built up during cooking by turning off the oven for the last few minutes of cooking time
Fridge and freezer
There’s no way around your fridge and freezer using electricity all day, every day. So to help you avoid any wasted energy use, we’ve put together some tips on keeping them running efficiently.
1. Set your fridge and freezer to the right temperature
Make sure you’re not wasting energy (and food) by setting your fridge between 2-3°C and your freezer at -15°C
2. Avoid overpacking
Aim to keep 20% of the space free – overloading your fridge forces it to use more energy to stay cold
3. Close the door
- It takes about 45 minutes for your fridge to get back to its original temperature if the door is open for just 10-20 seconds.
- Knowing what you’re going to take out of the fridge before you open it and making sure the door is closed fully afterwards will help minimise electricity use
4. Let your food cool before putting it into the fridge or freezer
Putting hot food in your fridge will make it have to work extra hard to cool down the food and keep the fridge at the correct temperature
5. Don’t put your fridge beside the dishwasher or oven
Having appliances that expel heat (like an oven or dishwasher) beside your fridge and freezer will make them use more energy to stay cold
6. Defrost your freezer every 6 months (or when the frost is ¼ of an inch thick)
Utility room: laundry & cleaning tips
Washing
- Wash clothes at 30°C if possible
- Use 'Eco' settings – even if they take longer, they’re more energy efficient
- Wait until you have a full load to wash rather than doing two half loads
- If you’ve a smart meter and are on a Time of Use plan, using your washing machine or tumble dryer at the time when your electricity tariff rates are lower will save you money
Drying
- This is an obvious one, but avoiding using a tumble dryer will save a lot of energy
- When you do use a tumble dryer, make sure to put heavy and light clothes into separate loads
- Heated clothes airers can be a good compromise for winter days – they’re quite cheap to run (about 14c per hour) and you’ll get the benefit of the residual heat in the room that they’re in
Living spaces: washing, grooming & recreation tips
As you can see, most of the devices we use for recreation don’t use as much energy as those for cooking and cleaning! However, there are some simple changes you can make to help reduce your energy consumption in these areas too.
1. Unplug or switch off devices at the socket when you’re not using them
Appliances on standby use about 20% of the energy they would consume if they were being actively used. So, for example, if you watch 3 hours of television a day and the other 21 it’s on standby, by switching it off completely when not in use, you could save over €76 a year
2. Take slightly shorter showers
If you can reduce your time in the shower by 3 minutes a day, you could save about €83 a year
3. Modern electric blankets are more energy efficient than they used to be
They now cost about 7c an hour to run (depending on which setting you use), so used sparingly they can be an efficient solution for staying warm during cold winter nights
Work from home tips
Working from home can increase your energy bills, but there are a few simple things you can do to reduce unnecessary energy use.
- Fully shut down or unplug devices when they’re charged or not in use
- Switch to LED bulbs - traditional bulbs use about 6 times as much electricity as LED bulbs
- Set up your home office or workspace so that you’re not blocking radiators and preventing the flow of heat into the room
- When it’s not too cold outside, consider turning off radiators in rooms you don’t use regularly. Or try using a portable heater instead of central heating if you spend most of the day in one room
Home heating tips
Making sure your home is warm enough when it's cold outside isn’t something to compromise on. So, we’ve put together some ways you can make sure your heating is running efficiently and you’re not wasting energy to keep your home cosy.
1. Maintenance is important for energy efficiency
- Bleed your radiators regularly
- Service your boiler every year
2. Take control of your heating
- You may already be doing this, but reducing your central heating by 1°C can lower your overall heating bills by 10%
- Use timers or smart heating controls so your heating only comes on when it’s needed
- Use the radiator valve to turn the temperature down or to turn off the radiator completely in rooms you’re not in a lot
- Set your gas boiler at 65-70°C and your hot water temperature to 60-65°C to help avoid overheating
- Insulating your hot water cylinder will make it more energy efficient

Home improvement tips
Energy-efficient homes reduce unnecessary energy consumption, increase the use of renewable energy, and ultimately resulting in lower energy bills.
The following tips can be expensive so may not be for everyone, but making your home more energy efficient will mean longer term savings and a more comfortable home.
Insulation
Energy-efficient homes should be well-insulated and sealed against draughts. About 25% of the heat loss in your home happens through your attic, so adding or updating attic insulation can reduce your annual energy bills dramatically. Wall insulation is another good idea to prevent heat escaping your house, particularly if your house was built before the 1990s.
Solar Panels
Adding Solar PV Panels to your house can supply power to appliances in your home, as well as heating water. After this, any remaining excess power feeds the grid (which can earn you money). Check out our Beginner’s Guide to Solar Energy for more information.
Heat pumps
A heat pump is a device that measures and controls your home’s climate by distributing the heat that is already available in the air. Heat pumps are one of the most efficient ways to heat a house and can cut home heating emissions by 60%. Take a look at our Heat Pump Guide for more information.
For more information on energy efficient solutions, see our Energy Efficiency Guide.
While some of the above tips require significant investment, don’t forget the government offer SEAI grants to assist homeowners with energy efficient upgrades. For more information on this, read our guide on securing an energy upgrade grant or visit the SEAI website.
