If you're installing or replacing an exhaust fan in your Singapore home, the total cost typically runs SGD 120 to SGD 450 — covering both the fan unit and professional installation. This guide breaks down every cost factor for HDB flats, condominiums, and landed homes, so you can budget accurately before calling a contractor.
What Affects Exhaust Fan Installation Cost in Singapore?
Several factors determine how much you'll pay for exhaust fan installation:
- New installation vs. replacement: Replacing an existing fan is cheaper (no new wiring or ducting). A fresh installation — especially in a room without existing ventilation — costs significantly more.
- Fan type and brand: Budget exhaust fans start from SGD 30, while premium models from Panasonic or KDK can cost SGD 150–300.
- Ducting requirements: If a new duct hole needs to be drilled through the wall or ceiling, add SGD 100–400 for the additional labour and materials.
- Wiring complexity: Fans with built-in timers, humidity sensors, or separate switch circuits require more electrical work.
- Location: Toilet and bathroom fans are easiest to install. Kitchen exhaust fans that vent to the exterior may need longer ducting runs.
Exhaust Fan Installation Cost Breakdown (2026)
| Scope of Work | Estimated Cost (SGD) |

| Fan unit only (mid-range, 200mm) | $80 – $150 |
| Fan unit only (premium, Panasonic / KDK) | $150 – $300 |
| Labour — like-for-like replacement | $60 – $120 |
| Labour — new installation with existing wiring | $80 – $150 |
| Labour — new installation with new wiring | $150 – $300 |
| New duct hole (drilling through wall/ceiling) | $100 – $400 |
| Typical total (replacement, mid-range fan) | $150 – $280 |
| Typical total (new installation, premium fan) | $300 – $500 |
HDB Flats: Rules and What to Expect
HDB flats come with standard duct openings in bathrooms and toilets — which is good news, as you generally won't need to drill new holes. Most HDB exhaust fan replacements are straightforward: remove the old unit, fit the new one into the existing aperture, and reconnect the wiring.
However, if your HDB flat does not have an existing exhaust duct (common in older 1970s–1980s blocks), you will need HDB approval before drilling a new opening in the wall. This process involves submitting an application through HDB's e-Service portal and may add both time and cost to your project.
For wiring work beyond simple fan replacement, all electrical installations in HDB flats must be carried out by a Licensed Electrical Worker (LEW) registered with the Energy Market Authority (EMA). This is a legal requirement — not optional.
Condominiums and Landed Homes
In condominiums, exhaust fans typically vent into a common shaft managed by the Management Corporation Strata Title (MCST). Before making any modifications to ducting, check with your MCST — some require prior approval for changes to ductwork.
Landed properties have the most flexibility. Without shared walls or centralised duct systems, you can install ducting that vents directly to the exterior. This is ideal for kitchen exhaust fans handling heavy cooking, though the longer duct runs (sometimes 3–5 metres) will increase installation cost.
Bathroom vs Kitchen vs Toilet: Cost Differences
Bathroom exhaust fans (150mm–200mm): These are the most common installation type in Singapore homes. Standard replacement costs SGD 120–220 all-in. Premium models with built-in humidity sensors or timers add SGD 50–100 to the fan cost but reduce the need for manual operation.
Kitchen exhaust fans (200mm–250mm): Kitchen installations are more complex because cooking generates grease-laden air that requires a higher-rated fan and, ideally, a grease filter. Expect to pay SGD 200–400 for a quality kitchen exhaust fan with installation, plus extra if new exterior ducting is needed.
Toilet exhaust fans (100mm–150mm): The simplest and cheapest installation. Basic 100mm fans cost from SGD 30, and a straightforward replacement by a licensed electrician typically costs SGD 100–180 all-in.
How to Save on Exhaust Fan Installation
The simplest way to keep costs down is to choose a like-for-like replacement — same size, same duct direction — so no structural work is needed. Buying your fan unit from a retailer (rather than through the contractor) and supplying it yourself can also save SGD 20–50, as contractors typically mark up their supply price.
If you're renovating and having other electrical work done at the same time, bundle the exhaust fan installation into the same job — electricians often reduce per-item labour when multiple tasks are done in a single visit.
When Do You Need an EMA-Licensed Electrician?
Under Singapore's Electricity Act, any electrical installation work — including wiring a new exhaust fan circuit or upgrading an existing one — must be carried out by an EMA-licensed electrician or Licensed Electrical Worker (LEW). Simple plug-and-play replacements that involve no wiring changes can be done by a general handyman, but if new wiring, a new switch, or a timer circuit is involved, always engage a licensed professional. Non-compliant work may void your home insurance and create fire hazards.
