A practical HDB retrofit with DIY-friendly Zigbee hardware lands between SGD 1,500 and SGD 4,000 installed; a KNX or Lutron fit-out in a 1,000 sq ft condo stays near SGD 9,000 to SGD 20,000; and a full Control4/Crestron AV-and-lighting install on landed property starts around SGD 35,000 and climbs past SGD 70,000 once motorised blinds, CCTV, and multi-room cinema are invoiced.
1. The Singapore Cost Baseline: HDB vs Condo vs Landed
Power over the cost starts with the shell, not the app. In an HDB 4-room retrofit, the data runs are surface trunking because false ceilings are plasterboard and plaster walls aren’t chased without a hacking permit. Contractors charge SGD 120–180 per Cat6 point installed, including drilling and termination. Lighting circuits already wired to the DB switch over to smart dimmers at SGD 60–90 per gang, using the existing conduits.
Condos change the math: a 1,000 sq ft condo multizone layout needs more RF repeaters and a proper patch panel near the riser. Many condos enforce working hours for drilling, so integrators price in two or three visits. Expect SGD 8,000–20,000 for a centralised Zigbee or Lutron system with 20–30 zones of lights and six data drops.
Landed properties are a different job: multi-gang distribution boards, 63A DB backup, and lighting suppression modules for the network rack. The electrical work must be signed off by a Licensed Electrical Worker (LEW); unlicensed DIY fixed 230V wiring is not insurable. Full first-fit costs for landed run SGD 35,000–70,000 before you add a 4K projector screen or per-room HVAC control.
2. Hardware Line Items That Actually Appear on Quotations
Integrators quote by line item, and the gap between consumer retail and installer pricing is fixed. Typical Singapore street prices from reputable distributors and showroom stockists, as of Q2 2025:
– Aqara Hub M2 – SGD 98
– Aqara H1 smart wall switch (1-gang) – SGD 39
– Aqara door/window sensor – SGD 25
– Lutron Caseta starter kit (bridge + 2 dimmer) – SGD 220
– Lutron QS wallbox dimmer module – SGD 180–260
– KNX 8-channel binary input module – SGD 220
– KNX IP/Ethernet interface – SGD 250
– UniFi 8-port PoE switch (150W) – SGD 160
– UniFi G5 bullet camera – SGD 230
– Somfy 28mm motor with rail for 2.8m window – SGD 900–1,200 per window installed
Note that cloud-only hubs (Lutron Caseta, Aqara M2) need stable 2.4 GHz Wi-Fi coverage. If you don’t have a proper mesh backbone, the integrator will upsell a UniFi AP setup at SGD 200–400 per access point, plus cabling.
3. Installer Pricing: Cabling, Drilling, and LEW Rates
Most quotations separate materials from labour. Here’s what the labour sheet looks like for a mid-size condo project:
| Work item | Rate |
|---|---|
| Cat6 23AWG solid core data point, terminated and labelled | SGD 120–180 per point |
| 230V lighting point relocation or new box | SGD 90–130 per point |
| LEW-compliant DB wiring for smart dimmer rails | SGD 300–450 per day (LEW day rate) |
| Motorised blind rail installation and configuration | SGD 250–350 per window |
| Zigbee network commissioning (binding, scenes, voice) | SGD 60–120 per hour |
| ELV integrator project management | 12–18% of hardware subtotal |
Rates are higher for retrofit work where walls are solid plastered brick. A typical HDB installation with 3 data points, 4 smart switches, 2 wall tablets, and a hub ends up around SGD 3,800–4,500 after the integrator’s margin. A new-build condo pre-wired by the developer shaves off roughly 30–40% of cabling labour because the runs are in exposed ceiling before the gypsum goes up.
4. The Subscription and Licence Layer You Cannot Invoice Away
Hardware is the one-time purchase; the providers behind the scenes take recurring fees, and Singapore integrators nearly always quote these as separate annual items.
– Singtel/Alarm.com police-response monitoring: SGD 19.90–35.90 per month. This layers over home automation hubs and includes a cellular fallback module.
– Control4: a perpetual system licence is SGD 700–900 per install, and some dealers bundle it into the first-year service contract. After that, add-on module licensing is per-driver.
– Crestron One annual cloud fee: SGD 150–200, required for remote firmware and the app’s Twilio-based notification service.
– KNX programming software (ETS): no monthly fee, but the ETS6 Professional licence is SGD 1,250 one-time. Only integrators need this, though an advanced owner will ask that the project file be transferred.
– UniFi Protect: free with a local UNVR, but the cloud backup tier is USD 29 per month for more than 30 cameras or extended storage.
These add roughly SGD 30–90 per month to an occupied landed property. If the installer skips subscriptions with the pitch of “local only”, you lose off-site monitoring and push notifications—a common failure point for HDB buyers who travel frequently.
