Tips to Reduce Your Electricity Bill

1. Start with your air-conditioner

Aircon is typically the single largest line item in a Singapore household's electricity use — see our usage estimation guide for why. A few adjustments go a long way:

• Set the thermostat a couple of degrees higher — every degree lower increases running time and cost.
• Use the timer or sleep mode instead of running it all night at full power.
• Clean or replace the filter regularly — a clogged filter makes the unit work harder for the same cooling.
• Close doors and windows while it's running, and avoid direct sun on the unit's outdoor condenser where possible.

2. Use fans to supplement, not replace

A standing or ceiling fan draws a fraction of an aircon's power. Running a fan alongside the aircon at a slightly higher thermostat setting — or using a fan alone on cooler nights — can meaningfully cut aircon runtime without much comfort trade-off.

3. Cut phantom load

Chargers, set-top boxes, and appliances left on standby draw power even when not in active use. Switching off at the wall (or using a power strip you can switch off in one go) for devices you're not using adds up over a month.

4. Choose efficient appliances and lighting

Singapore's mandatory energy labelling scheme rates appliances like fridges and aircon units with ticks — more ticks means better efficiency for the same output. LED bulbs also use a fraction of the power of older lighting for the same brightness, and pay for themselves quickly given how many hours lighting runs each day.

5. Run full loads, not partial ones

Washing machines, dishwashers, and similar appliances use roughly the same energy whether the load is full or half-empty. Batching laundry into full loads instead of frequent small ones reduces the number of cycles you run.

6. Check your usage regularly

SP Group's online account shows your consumption history month by month, which makes it easy to spot a sudden jump — a sign an appliance may be faulty or a habit has crept in — before it shows up as a much bigger bill.

7. Then make sure you're on the right plan

Usage habits only get you so far — the rate you're paying per kWh matters too. Once you've trimmed usage, compare current plans on our comparison page to make sure you're not overpaying on rate as well. See our guide on fixed vs discount-off-tariff plans if you're unsure which pricing structure suits you.
