Smoke alarm installation and compliance across Brisbane
Smoke alarm installation in Brisbane costs $120 per alarm installed (new alarms or upgrades), covering supply, installation, interconnection and testing, GST inclusive. A typical 3-bedroom home needs 4 to 5 interconnected photoelectric alarms ($480 to $600 total), which includes a free wall controller and compliance certificate.
All Queensland homes must have interconnected photoelectric smoke alarms by 1 January 2027 under the Fire and Emergency Services Act 1990. Single alarm replaced, full-house upgrade or urgent pre-sale certification, we quote fixed prices upfront with no callout fee.
What's included in our smoke alarm service?
- Assessment of current alarm locations, types and condition
- Identification of required alarm positions under QLD legislation
- Removal of old non-compliant alarms (ionisation, standalone battery, expired units)
- Installation of interconnected photoelectric smoke alarms in all required locations
- Interconnection testing to confirm all alarms trigger together
- Free wall controller and compliance certificate with 4 or more alarms
- Labelling and documentation of alarm locations
- Explanation of testing, maintenance and battery replacement schedule
- Compliance confirmation suitable for property sales, leases and insurance
We use quality 10-year sealed-battery wireless interconnected photoelectric alarms that meet AS 3786:2014. No hardwiring is needed in most retrofits, so there's less disruption, faster installation and no ceiling or wall damage.
Older homes vs newer estates
Requirements vary with the age, layout and construction of the property. We work in everything from older timber and brick homes to modern two-storey estates, and the approach changes for each.
In older suburbs like Kallangur, Petrie and Lawnton, we commonly find ionisation alarms (no longer compliant), standalone battery units with no interconnection, alarms in the wrong locations, and missing coverage in bedrooms or hallways. These homes usually need a full upgrade to interconnected photoelectric alarms with correct placement.
In newer estates like North Lakes, Mango Hill and Griffin, homes built after 2017 usually already have hardwired interconnected alarms, but pre-2017 stock often still has non-compliant standalone alarms that need upgrading before 2027.
Multi-storey homes get alarms on every level. For unusual layouts, long hallways or open-plan living, we choose positions that meet both the legislation and practical coverage needs.
Who needs a smoke alarm upgrade?
Homeowners preparing for 2027
If your home still has standalone battery alarms, ionisation alarms, or alarms only in hallways (not bedrooms), you need an upgrade before January 2027.
Landlords and property managers
Rental properties must already comply. If your investment property hasn't been upgraded, it's currently non-compliant. We work with property managers across North Brisbane to schedule upgrades efficiently across portfolios, with priority scheduling and batched jobs.
Selling or leasing a property
Properties being sold or leased must have compliant alarms at the time of contract or lease signing. We offer same-day installation and compliance confirmation for urgent situations.
New builds and renovations
New builds need hardwired interconnected alarms as part of the electrical fit-out. Renovations that trigger building approval may also need alarm upgrades as a condition of certification.
How much does smoke alarm installation cost?
$120 per alarm incl. GST, for new alarms and upgrades, covering supply, installation, interconnection and testing. Book 4 or more and you also get a free wall controller and compliance certificate. No callout fee and no hidden extras.
If your property needs more alarms than the standard layout, the same $120 per alarm rate applies. Hourly work is $220 per hour incl. GST (1-hour minimum); after-hours rates are quoted on the call.
What can change the price?
Roof and ceiling access, distance between alarm locations, whether interconnection is required, whether existing alarms or wiring must be replaced, and any extra labour for difficult access or routing. A standard install is straightforward; more complex homes need more labour and sometimes extra electrical work. All extras are explained before work begins.
Simple flat rate: $120 per alarm incl. GST, whether it's a new alarm or an upgrade. 4 or more alarms includes a free wall controller and compliance certificate.
| Home size | Price (incl. GST) |
|---|---|
| Per alarm, new or upgrade (supplied, installed, interconnected, tested) | $120 |
| Wall controller and compliance certificate (4+ alarms) | Free |
| 3-bedroom home, 4 to 5 alarms | $480 to $600 |
| 4-bedroom home, 5 to 6 alarms | $600 to $720 |
| Larger or multi-storey homes | Quoted on site |
| Callout fee | $0 |

QLD smoke alarm law: what you need to know
Queensland's legislation (amended 2022) requires interconnected photoelectric smoke alarms in specific locations. Rentals and properties being sold or leased must already comply. Owner-occupied homes must comply from 1 January 2027.
- Photoelectric type (not ionisation)
- Interconnected: when one sounds, all sound
- In every bedroom
- In hallways connecting bedrooms to the rest of the home
- On every level of the property
- Hardwired or 10-year sealed lithium battery
| Date | Requirement and who it affects |
|---|---|
| 1 Jan 2017 | All alarms must comply with AS 3786:2014; expired or faulty alarms replaced. All QLD properties. |
| 1 Jan 2022 | Interconnected photoelectric alarms in every bedroom, hallway and level. Rentals and properties sold or leased. |
| 1 Aug 2025 | New REIQ contract requires smoke alarm compliance disclosure at sale. All QLD sellers. |
| 1 Jan 2027 | All existing owner-occupied homes need interconnected photoelectric alarms. All QLD homeowners. |
What happens if you don't comply?
Non-compliance can mean penalties, insurance complications and, most importantly, less protection for your household in a fire. For landlords, it can also affect your ability to lease the property.
Official resources and standards
- Queensland Fire Department: smoke alarm requirements
- QLD Government: smoke alarm legislation
- Fire and Emergency Services Act 1990 (Qld)
- AS 3786:2014 Smoke Alarms (Standards Australia)
- CSIRO ActivFire: verified compliant smoke alarms register
Note: AS 3786:2014 has been superseded by AS 3786:2023, which adds requirements for radio-linked alarms and temporary hush functions. QLD legislation currently references AS 3786:2014 via the NCC, but alarms meeting AS 3786:2023 are also compliant.
Common problems we find
Compliance isn't just having alarms on the ceiling. Type, position, interconnection and condition all matter for the law and for real life safety.
Ionisation alarms
No longer compliant in QLD. They must be photoelectric.
Wrong locations
Missing from bedrooms, or too close to kitchens or bathrooms.
No interconnection
Standalone alarms are non-compliant for sales, leases and post-2027 homes.
Expired alarms
Past their 10-year life. The date is stamped on the unit and often unchecked.
Why interconnection matters, and one more common issue
We also regularly find alarms painted over, covered or disconnected during renovations.
A properly installed interconnected system means when one alarm detects smoke, every alarm in the house sounds at once. That gives people in distant bedrooms the earliest possible warning, which is the whole point of the legislation change.
What we find in your suburb
Every suburb across North Brisbane has different housing stock, switchboards and ceiling access. We install smoke alarms daily across these areas and know the common issues in each.
Bookings of 4 or more alarms include a compliance certificate confirming your property meets current QLD requirements, essential for rentals, sales and insurance.
North Lakes, Mango Hill, Griffin
North Lakes (2000s to 2020s estates, single and two-storey): modern switchboards, ceiling access usually good. 4 to 6 alarms typical.
Mango Hill (2005+ builds): similar to North Lakes. Often already hardwired but not interconnected, so the upgrade path is clear.
Griffin (2010+ estates): newer builds may already have some interconnected alarms, so partial upgrades are common.
Redcliffe, Scarborough, Margate, Deception Bay, Rothwell, Kippa-Ring
Redcliffe, Scarborough, Margate (1960s to 1980s Queenslanders and newer units): older timber frames, sometimes limited ceiling space. Wireless RF interconnection is ideal.
Deception Bay, Rothwell, Kippa-Ring (1980s to 2000s lowset brick): standard ceiling heights and good access. Quick installs, most done in under 2 hours.
Kallangur, Petrie, Bray Park, Strathpine, Brendale, Albany Creek
Kallangur, Petrie, Bray Park (1980s to 2000s brick and tile): older switchboards may need a minor upgrade. Ceiling access generally straightforward.
Strathpine, Brendale, Albany Creek (1970s to 1990s established suburbs): older alarms commonly expired (10+ years). Full replacement usually needed.
Caboolture, Morayfield, Burpengary, Narangba, Murrumba Downs, Kurwongbah
Caboolture, Morayfield (older Queenslanders and newer estates): a wide range. Some need a full rewire to interconnect, others a simple wireless swap.
Burpengary, Narangba (1990s to 2010s single-storey family homes): standard installs. Acreage properties may need extra alarms for outbuildings.
Murrumba Downs, Kurwongbah (acreage and newer estates): larger homes may need 6 to 8 alarms. We bring extra stock for same-day completion.
Sandgate, Bracken Ridge, Aspley, Eatons Hill, Warner, Cashmere
Sandgate, Bracken Ridge, Aspley (1960s to 1980s character homes): high ceilings on Queenslanders and limited roof cavity in some. Wireless is the preferred solution.
Eatons Hill, Warner, Cashmere (2000s+ family estates): modern builds, often two-storey, needing interconnected alarms on both levels.

Smoke alarm FAQs
How much does smoke alarm installation cost?
$120 per alarm installed incl. GST, for new alarms and upgrades, including supply, installation, interconnection and testing. 4 or more alarms includes a free wall controller and compliance certificate. Most 3-bedroom homes need 4 to 5 alarms ($480 to $600 total).
What type of smoke alarms are required in QLD?
Interconnected photoelectric smoke alarms. Ionisation alarms are no longer compliant. Alarms must be hardwired or have a 10-year sealed lithium battery.
Where do smoke alarms need to be installed?
In every bedroom, in hallways connecting bedrooms to the rest of the home, and on every level. This applies to all QLD residential properties.
When is the QLD smoke alarm deadline for owner-occupied homes?
1 January 2027. Rental properties and properties being sold or leased must already comply.
Do you offer same-day smoke alarm installation?
Yes, across North Brisbane. It's especially useful for urgent pre-sale or pre-lease compliance. Call 0474 207 609 to check availability.
Do I need an electrician to install smoke alarms?
Hardwired smoke alarms must be installed by a licensed electrician. Wireless interconnected alarms with sealed batteries can technically be owner-installed, but professional installation ensures correct placement, proper interconnection testing and compliance documentation.
What is a wall controller and why is it free?
A wall controller is a switch mounted on your wall that lets you test, silence and locate your interconnected smoke alarms. If cooking steam sets them off, you hush every alarm from the wall instead of climbing on furniture or pulling an alarm off the ceiling, and the locate button shows which alarm triggered. We include one free when you book 4 or more alarms because it makes the system much easier to live with.
How many smoke alarms does a typical house need?
A 3-bedroom single-storey home typically needs 4 to 5 (one per bedroom plus hallway). A 4-bedroom home usually needs 5 to 6. Two-storey homes need extra alarms on each level. We confirm the exact count during assessment.
Can you upgrade smoke alarms in a rental property?
Yes. We work with landlords and property managers across North Brisbane and can coordinate directly with your property manager.
What areas do you cover for smoke alarm installation?
North Lakes, Mango Hill, Griffin, Murrumba Downs, Kallangur, Redcliffe, Deception Bay, Narangba, Petrie, Lawnton, Aspley, Chermside, Bridgeman Downs and surrounding North Brisbane suburbs.
Are wireless interconnected alarms compliant in QLD?
Yes. Wireless interconnected photoelectric alarms with 10-year sealed lithium batteries are fully compliant. They're the most common retrofit choice because they don't need new wiring.
What happens if my smoke alarms aren't compliant when I sell?
Non-compliant alarms can delay or complicate a sale. The seller is responsible for compliance at the time of contract. We offer same-day installation for urgent pre-sale situations.
