Household electricity bills fall this quarter. The tariff for homes drops 10.4 per cent to 28.59 cents per kWh before GST from 1 October to 31 December 2026, down 3.32 cents from the July to September rate of 31.91 cents. With 9 per cent GST, the October to December rate is 31.16 cents per kWh.
For a family in an HDB four-room flat, the average monthly bill falls by S$12.99 before GST, from S$124.87 to S$111.88.
The cut undoes most of the July rise. The July to September rate of 31.91 cents was the highest quarterly household tariff since at least the start of 2025, when it stood at 28.12 cents, and the new 28.59-cent rate is back close to that level.
What the cut looks like by flat type
SP’s averages for each housing type, all before GST, are below. The four-room figure assumes the type’s average use of 391 kWh a month.
- HDB one-room: S$41.72, down S$4.84
- HDB two-room: S$55.88, down S$6.49
- HDB three-room: S$81.38, down S$9.45
- HDB four-room: S$111.88, down S$12.99
- HDB five-room: S$131.72, down S$15.30
- HDB executive: S$161.10, down S$18.71
- Private apartment: S$156.02, down S$18.12
- Terrace house: S$241.35, down S$28.02
- Average across all households: S$124.67, down S$14.47
Every household gets the same 10.4 per cent cut, because the whole change is in the per-kWh rate. In plain terms, every 100kWh costs S$3.32 less than it did in September, so a home that runs two air-conditioners through the night saves more in dollars than one that does not.
The tariff applies to households buying electricity from SP Group. Homes on a retailer plan in the Open Electricity Market pay what their contract says, and only plans pegged to the SP tariff, such as discount-off-tariff plans, move with it.
Why the rate fell, and why it may not last
The tariff has four parts. Energy costs, paid to the power generation companies, fall to 22.18 cents from 25.50 cents and account for the whole 3.32-cent drop. Network costs stay at 6.10 cents, the Market Support Services Fee at 0.23 cents and the market administration and power system operation fee at 0.08 cents.
SP sets the energy component each quarter from average natural gas prices over the first two and a half months of the previous quarter. This quarter’s figure reflects lower gas prices between 1 July and 15 September 2026.
The respite may be short. Global fuel prices have risen since September because of escalating tensions in the Middle East, and if that persists, tariffs are expected to rise for the January to March 2027 quarter.
