Protecting your home and loved ones starts with a working smoke alarm system. At Hilton Electrical, we take fire safety seriously—and we’re here to make sure your smoke alarms are installed correctly, meet all legal requirements, and are built to last. Whether you’re upgrading an older system or installing new alarms, Your Mate in the Trade™ has you covered across Perth.
If you’re wondering what it costs to get a smoke alarm installed in Perth, prices start from $249 for replacing an existing alarm, and $329 for a new hard wired alarm. The job is usually quick—in most cases, our electricians can replace a smoke alarm in under an hour.
You might be tempted to install a smoke alarm yourself, but in Western Australia, any hardwired or interconnected system must be installed by a licensed electrician. Even battery-powered alarms benefit from expert placement and installation. We ensure everything is done right and to code, so you can rest easy knowing your home is protected.
In WA, mains powered smoke alarms are required by law in many situations, including:
These alarms must be installed by a licensed electrician, and wherever possible, they should be interconnected to provide full-home coverage. We stay across all local legislation to ensure your property complies with WA law. If hardwiring isn’t feasible, we recommend installing 10-year lithium battery smoke alarms—a reliable alternative that eliminates the need for annual battery replacements.
Not all smoke alarms are created equal. We recommend photoelectric smoke alarms, which are more effective at detecting slow smouldering fires common in homes. These are now the preferred standard across Australia. If your current alarms are the old ionisation type, we strongly recommend replacing them.
Mains powered and interconnected alarms provide the highest level of protection, offering reliable, continuous monitoring without relying solely on batteries. If hardwiring isn’t an option, 10-year lithium battery alarms are your next best choice—no more beeping from flat batteries, no climbing ladders to replace them, and far fewer risks of battery failure. Budget 9-volt alarms are available but require annual battery changes and often don’t support interconnection. We can also advise on wireless alternatives if needed.
Our team will assess your home’s layout and determine the best locations for installation, ensuring full coverage without false alarms. Generally, alarms should be installed on the ceiling in hallways outside bedrooms, but we know the nuances—we’ll make sure each unit is positioned for maximum safety and minimum disruption.
If you’re renovating or building, we can pre-wire alarms or integrate them with your smart home setup. And yes, we can replace old alarms or fit new ones where you had lights or other fixtures previously. All work is done neatly and professionally, with no mess left behind.
Smoke alarms need to be tested regularly. We recommend pressing the test button every month and having the unit cleaned and inspected once a year. If your alarm is chirping or beeping randomly, give us a call—it could be a sign of battery issues or sensor problems.
Most smoke alarms need replacing every 10 years. We handle full replacements, upgrades from battery to hardwired units, and can swap out malfunctioning alarms with reliable models that meet Australian Standards. If your remote or interconnected system isn’t working as it should, we can troubleshoot and fix it.
When it comes to fire safety, there’s no room for shortcuts. Every Hilton Electrical smoke alarm installation is backed by a workmanship guarantee, and we only use products we trust from leading brands. If anything goes wrong, Your Mate in the Trade™ is just a phone call away.
We also offer regular safety checks and can set up reminders for future replacements or maintenance. Whether you’re a homeowner, investor, or property manager, you can count on us for prompt, reliable service that keeps your property safe.
