Owning a rental property comes with a long list of responsibilities, and electrical safety is one that quietly sits near the top. It rarely causes trouble until it does, and by then the stakes are high. So how often should a landlord actually book an electrical inspection? The honest answer is that it depends less on a fixed rule and more on the age of the property, what has happened to it, and how seriously you take your duty of care.
Let’s break it down.
There Is No Fixed Legal Interval in NSW
Plenty of landlords assume there is a set timetable they are legally bound to follow. In New South Wales, that is not the case. The state has chosen not to mandate a routine electrical inspection interval for residential rentals, which puts it in a different position to Victoria, where a check is required every two years.
That absence of a hard rule is often misread as permission to do nothing. It is not. Under the Residential Tenancies Act 2010, every landlord must provide a property that is fit to live in and keep it in a reasonable state of repair. A dangerous electrical installation fails that test. Given that electrical faults and appliances are behind roughly 40 percent of house fires in NSW homes each year, the risk is real, and so is the liability if a preventable fault causes harm.
The practical takeaway is that inspections are how you satisfy your duty of care, even though no law counts the years for you.
A Sensible Baseline: Every Five Years
If there is no legislated number, what should you aim for? Across the industry, and among many landlord insurers, a full electrical inspection every five years is treated as the sound best-practice cycle for a rental in reasonable condition. It strikes a fair balance between cost and caution.
For a newer home with modern wiring and a recently updated switchboard, five years is a comfortable rhythm. For an older property, especially one that still carries decades-old wiring or a ceramic fuse board, tightening that up to every three years is the wiser move. Ageing installations simply have more that can go wrong, and problems tend to develop out of sight.
Booking a licensed electrician on this cycle also leaves you with dated, documented proof that you acted responsibly. That paper trail is worth a great deal if a fault ever leads to an insurance claim or a tenancy dispute.
The Triggers That Override the Schedule
A calendar cycle is only half the picture. Certain events should prompt an inspection no matter when the last one took place.
Book one before a new tenant moves in, particularly if the property has sat empty, changed hands, or not been rented for a while. Starting a tenancy with a clean bill of electrical health protects everyone.
Any fault a tenant reports deserves a proper look rather than a quick patch. A tripping or faulty safety switch counts as an urgent repair under NSW rules and should be attended to without delay. Renovations are another clear trigger, since electrical work has to be carried out by a licensed electrician and larger jobs require a compliance certificate.
Weather is the trigger people forget. After a storm, flood or fire, wiring can be damaged in ways you cannot see. Power should not be fully restored until the system has been checked following storm damage by a qualified electrician.
Smoke Alarms Are the Exception With a Firm Deadline
While the broader electrical inspection has no legislated frequency, smoke alarms do carry enforceable obligations. NSW rules require them to be maintained and confirmed working, and the landlord or agent must check each one before a tenancy begins. Staying on top of smoke alarm compliance is non-negotiable, and it slots neatly into a wider inspection visit rather than being handled separately.
Older Properties Deserve Closer Attention
The age of the building changes everything. Many older rentals across Sydney were wired long before today’s appliances and power demands existed, and a good number still lack proper safety switch coverage on every circuit.
Safety switches are the fastest-acting protection against electric shock, cutting power in milliseconds when they sense current leaking to earth. If an inspection reveals gaps, safety switch installation and often a switchboard upgrade will be recommended. These are among the highest-value improvements a landlord can make, because they remove genuine fire and shock hazards while cutting down the nuisance tripping that frustrates tenants in older homes.
When the Network Forces Your Hand
Occasionally the prompt for action is not your inspection schedule but a notice from the electricity network. If your property receives an electrical defect notice, it must be resolved promptly by a licensed electrician. Leaving one unaddressed risks disconnection and puts you in breach of your maintenance duty, so treat it as a priority the moment it arrives.
Keep Records of Everything
Whatever schedule you land on, document it. Record every inspection, test and repair, along with the electrician’s name and licence number and the date of the work. Solid records support your insurance position, reduce the chance of disputes, and show the due diligence that keeps you protected as a landlord.
The Short Answer
There is no legally required interval in NSW, but the responsible approach is straightforward. Aim for a full inspection every five years, or every three for older homes, add a check at each major trigger point, and stay current with your smoke alarm obligations. Do that, and you are meeting your duty of care while keeping your tenants and your investment safe.

Frequently Asked Questions
Is there a legal minimum for how often landlords must inspect electrics in NSW?
No. NSW does not set a mandatory inspection interval for residential rentals, unlike Victoria’s two-yearly requirement. Landlords are still legally bound under the Residential Tenancies Act 2010 to keep the property safe and in reasonable repair, so regular inspections remain the practical way to meet that duty.
What is a reasonable inspection schedule for a rental property?
A full electrical inspection every five years suits most rentals in good condition, while older properties with ageing wiring or fuse boards are better checked every three years. On top of that, always inspect before a new tenancy, after any reported fault, and following a storm, flood or fire.
Who is allowed to carry out an electrical inspection on a rental?
Only a licensed electrician can legally inspect, test and repair the electrical installation in a rental property. Using a licensed professional also ensures the work is documented correctly, which supports your insurance and compliance records.
