Best Electricity Plan by HDB Flat Type in Singapore
Last updated: 12 September 2026
The right electricity plan depends less on your flat type itself than on how much you actually use — but flat type is a reasonable starting estimate if you don't know your own usage yet. Here's what Singapore households typically use by home type, sourced from the Energy Market Authority, and what switching plans is actually worth at each level.
Average usage and switching savings, by home type
| Home type | Avg. usage | On SP tariff | On cheapest fixed plan | Monthly savings |
|---|---|---|---|---|
| 1- & 2-Room HDB | 164 kWh | $57 | $43 | $14/mo |
| 3-Room HDB | 259 kWh | $90 | $67 | $23/mo |
| 4-Room HDB | 357 kWh | $124 | $93 | $31/mo |
| 5-Room & Executive HDB | 435 kWh | $151 | $113 | $38/mo |
| Private Condominium | 480 kWh | $167 | $125 | $42/mo |
| Landed Property | 1137 kWh | $395 | $296 | $100/mo |
Illustrative, based on the current SP tariff (34.78¢/kWh) and the cheapest fixed-rate plan tracked on this site at time of writing (26.00¢/kWh). Both change — see the live comparison with your own usage for current figures.
Why the dollar savings grow with home size
The percentage saved by switching off the default SP tariff is roughly similar across home types — it's the same rate difference applied to different usage levels. But because larger homes use more electricity in absolute terms, the same percentage saving is worth more in dollars: a landed property saves several times what a 2-room flat does, simply because there's more usage for the cheaper rate to apply to. If you're in a larger home or have higher-than-typical usage (central air-con, a home office, an EV charger), switching plans is worth even more than these averages suggest.
Condo and landed homes: same rates, different scale
There's no separate electricity tariff or fee structure for private property versus HDB — every home in Singapore is billed on the same SP tariff and can choose from the same OEM retailer plans. The difference in typical bills comes entirely from usage: private condominiums and landed properties tend to have larger floor areas and more air-conditioning capacity to run, which is why average usage — and the potential savings from switching — is higher.
One thing that doesn't factor in at all: a condo's pool, gym, and other shared facilities run on electricity billed collectively through the MCST's management fees, not through any individual unit's SP account — so a condo with more shared facilities doesn't mean a higher personal electricity bill on that basis alone. The usage gap is really about your own unit: HDB flats almost always run wall-mounted split-unit air-con, while condos — especially larger or higher-end units — more often have ducted or multi-split (VRV/VRF) systems built in, sized for a bigger floor area. Whether a ducted system uses more or less electricity than an equivalent split system for the same cooling isn't something with a clear consistent answer either way — the bigger driver of higher condo usage is simply having more floor area and more rooms to cool, not the air-con system type itself.
