Smoke alarms
Plan a smoke alarm system that suits your home and Queensland’s requirements. We assess alarm locations, power supply and interconnection, then explain the work needed.
- Local electricians
- Tailored advice
- Ongoing support
Prepare for 1 January 2027
Queensland’s requirements extend to all existing private homes, townhouses and units by 1 January 2027. Homes being sold, leased or substantially renovated may already be subject to the upgraded requirements.
The requirements include interconnected photoelectric alarms in bedrooms and other prescribed locations. We assess your floor plan and existing installation rather than guessing a number of alarms.
What we look at
The right installation depends on the dwelling and the rules that apply to it.
- Bedroom, hallway and storey locations
- Photoelectric alarm type and compliance
- Interconnection between the alarms
- Hardwired or permitted sealed-battery arrangements
- Alarm age, condition and accessibility for testing
A practical installation plan
If you are renovating, we can coordinate alarm work with other electrical changes. For an existing home, we explain the proposed alarm arrangement, access and any wiring work before starting.
Hardwired smoke alarm work must be completed by a licensed electrician. Follow the manufacturer’s instructions for routine testing and maintenance, and ask us if an alarm repeatedly faults or chirps.

Good to know
Your questions, answered.
Do all Queensland homes need interconnected alarms?
The upgrade requirements apply to all existing private homes by 1 January 2027. Earlier requirements apply to specified situations such as sales and rentals. Check the current Queensland guidance for your dwelling.
How many alarms will I need?
It depends on bedrooms, levels and the layout. We assess the locations required for your property.
Should an old alarm be replaced if it still sounds?
Check its manufacture date and the replacement requirements. Alarms have a limited service life; sounding during a test does not override an expiry requirement.
