Why Homeowners Should Always Check a Tradie's Credentials

We've all been tempted to skip the paperwork and just hire the mate of a mate who says he can fix the roof. It feels faster, easier, and surely they know what they're doing, right? Wrong. This is one of those moments where cutting corners doesn't just cost you money — it can genuinely put your home and family at risk.

I've seen homeowners lose tens of thousands of dollars and face dangerous situations because they didn't bother checking whether their tradie was actually qualified to do the job. It's one of the most preventable problems in the home renovation and repair space, which is why I'm writing this.

What Credentials Actually Mean

Let's start with the basics. When we talk about credentials, we're not just talking about a diploma hanging on a wall. We're talking about:

• Current licences issued by your state's regulatory body
• Relevant qualifications and certifications for the specific work
• Insurance coverage that protects you if something goes wrong
• Registration with industry bodies where applicable
• Safety certifications (like White Card for construction work)

In Australia, building and trade work is heavily regulated — and that regulation exists because unqualified work causes real problems. Your state's building commissioner isn't trying to make life difficult; they're trying to keep people safe.

The Licence Question: Not Optional

Here's the thing: if a tradie is doing work that requires a licence in your state and doesn't have one, that's not a grey area. That's illegal. And it affects you, the homeowner.

Different states have different requirements. Electrical work, plumbing, gas fitting, and major renovations almost always require a current licence. But the specifics vary. In New South Wales, you might need a different level of licence than in Victoria. Your tradie should know their state's requirements cold — and if they don't, that's a red flag.

Ask to see the licence. Not a photo on their phone, not a story about it being at the office — actually see the physical licence or look it up yourself on the relevant state register. Most state regulators have online databases where you can verify a tradie's licence is current and actually covers the work they're quoting you for.

Insurance: Your Safety Net

If a tradie damages your home while working, or someone gets injured, their insurance is what protects you. An uninsured tradie? You're liable. You're paying for repairs out of your own pocket.

Ask for proof of current public liability insurance and, depending on the work, worker's compensation insurance. A legitimate tradie won't hesitate to show you this — it's as important to them as it is to you. Check that the insurance actually covers the type of work being done. A tradie who's insured for general repairs might not be insured if something goes wrong with electrical work.

The Hidden Cost of Dodgy Work

Here's what keeps me up at night: homeowners who hire unqualified tradies don't always realise the damage until much later. A dodgy electrical job might cause a fire six months down the track. Poor plumbing work can lead to hidden water damage inside your walls. Structural work done wrong can literally make your home unsafe.

When it's time to sell your home, you'll need to disclose any work that was done. If it wasn't done to standard, buyers' inspectors will spot it, and you'll either lose the sale or drop the price significantly. Some homeowners have had to completely redo major work because it wasn't done properly the first time.

Paying a bit more upfront for a qualified tradie is almost always cheaper than fixing a problem caused by someone who didn't know what they were doing.

How to Actually Check Credentials

Don't just take someone's word for it. Here's the process:

• Ask for their licence number and look it up online on your state's regulatory body website
• Request proof of public liability insurance — get the policy number and verify it's current
• Ask about relevant qualifications (apprenticeships, certifications, ongoing training)
• Check whether they're registered with relevant industry bodies
• Ask for references and actually contact them — ask specifically about whether the work was done to standard and completed on time
• Look at their online reviews, but take them with a grain of salt (both glowing reviews and complaints can be fake)

If a tradie gets defensive about showing you credentials, walk away. If they say their licence is "somewhere safe" or they "just renewed it and the paperwork is in the post," that's not good enough. Legitimate tradies have their credentials organised and accessible.

When Credentials Matter Most

Some jobs are more sensitive than others. You should be especially careful about checking credentials for:

• Electrical work (safety risk, building code requirements)
• Plumbing and gas work (health hazards, code requirements)
• Roofing and structural work (falls and building integrity)
• Asbestos removal (serious health risks)
• Any work that requires building permits

For smaller jobs like minor painting or fence repairs, the stakes are lower. But even then, you want someone who knows what they're doing.

The Permit Connection

If your job requires a building permit, that's actually a good sign that you should be careful about credentials. A tradie willing to skip the permit process is willing to skip other important steps. Building permits exist to ensure work meets safety standards. If you hire someone to do unpermitted work, you're taking on the legal and safety risk yourself.

Some homeowners think unpermitted work is cheaper, and sure, it might be in the moment. But when you're selling, or if something goes wrong, that decision comes back to bite you.

Using Verified Platforms

One way to make this easier on yourself is to use platforms like Your Tradie (yourtradieaustralia.com), which connects you with verified local tradies. But even there, you should still do your own checks. Verification helps, but it doesn't replace your own due diligence.

The Bottom Line

Checking a tradie's credentials takes maybe 20 minutes. Getting a job fixed because it was done badly can take weeks and cost thousands. It's genuinely one of the best investments of your time you can make as a homeowner.

A good tradie will respect you for asking. They understand you're protecting your home and your family. If someone gets annoyed at basic questions about their qualifications and insurance, that tells you everything you need to know — and none of it good.

Do the checks. See the licence. Verify the insurance. Get references. It's not paranoia; it's common sense.
