High Electricity Bill
Your bill keeps climbing but you're not sure where the energy is going.
Your Diagnosis
Based on your selection, your high electricity bill is most likely caused by heavy aircon use, devices left on standby, and inefficient lighting. These three areas account for up to 70% of the average Singapore household's electricity bill.
5 practical solutions
Switch to LED lighting throughout your home
LED bulbs use up to 75% less energy than incandescent bulbs and last 15–25 times longer. Replacing just 5 frequently used bulbs can save $75 or more per year.
Unplug devices on standby ('vampire power')
Devices on standby can account for 5–10% of your electricity bill. Use smart power strips or simply unplug chargers, TVs, and appliances when not in use.
Set your hot water heater to 60°C (140°F)
Many water heaters are set too high. Lowering to 60°C prevents scalding, reduces energy use, and still kills harmful bacteria.
Service your aircon every 3–6 months
A dirty aircon coil reduces efficiency by 20–30%, making your unit work harder and your bill higher. Regular servicing by a certified technician typically costs $25–$50 per unit and pays for itself within months.
Check your appliance NEA energy rating
When replacing any appliance, look for the NEA Energy Label. Each additional tick represents meaningful electricity savings. A 3-tick fridge vs a 1-tick fridge can save $80–$150 per year in electricity alone.
What You Should Do First
Raise your aircon to 24–25°C and add a fan — this alone can cut aircon costs by 20–30%.
Unplug chargers, TVs, and appliances at the socket when not in use — standby power adds up fast.
Replace your most-used bulbs with LED equivalents — they use 75% less energy and last years longer.
Check your SP Group app for your usage history — identify when your bill spiked to find the cause.
