You’ve got a full week booked solid. Every job lined up. Then your ute won’t start. Or a storm takes out your workshop roof. Or you pick up a back injury lifting a beam.
Suddenly, you’re not working. And when you’re not working, you’re not earning. The bills don’t stop — your mortgage, your tool loan payments, your staff wages, that insurance premium you just paid. A few weeks off can wipe out months of profit. I’ve seen blokes lose their whole business because they couldn’t cover three weeks of downtime.
That’s where business interruption insurance comes in. It’s not the flashiest cover, and most tradies I talk to have never heard of it. But if you rely on your hands, your tools, or your gear to make a living, this is the policy that keeps the lights on when you can’t work.
Let me break it down for you straight — no bull, no fine-print tricks.
What Is Business Interruption Insurance (and Why Should You Care)?
Business interruption insurance — sometimes called loss of profits or consequential loss insurance — covers the income you lose when something stops you from trading. It’s not the same as your public liability or tool cover. Those policies pay for repairs or legal claims. This one pays your lost earnings.
Think of it like this: your standard insurance gets you back on your feet. Business interruption keeps you standing while you heal.
It kicks in after an insured event — like a fire, flood, or theft — that damages your premises, tools, or stock. It covers your ongoing expenses (rent, loan repayments, wages) and the profit you would have made during the downtime.
For tradies, this is gold. If your workshop burns down, your public liability doesn’t pay for the six weeks you can’t work while it’s rebuilt. Business interruption does.
In 2026, Australian insurers are quoting between $400 and $1,200 per year for a basic business interruption policy for a sole trader, depending on your trade and annual turnover. If you’ve got staff and a bigger operation, expect $1,500 to $4,000 per year. Cheap for the peace of mind.
When Does Business Interruption Cover Kick In?
Not every hiccup qualifies. The trigger needs to be an insured event that physically stops you from trading. Here’s the breakdown:
Covered Events
- Fire or explosion — your workshop, shed, or office is damaged
- Theft or vandalism — your tools are stolen and you can’t complete jobs
- Storm, flood, or cyclone — damage to your premises or gear
- Accidental damage — a tree falls on your van, or a burst pipe floods your workshop
- Loss of utilities — if a mains water or power failure stops you working (check your policy wording carefully — some exclude this)
What’s Usually Not Covered
- Sickness or injury — that’s what income protection or trauma cover is for
- Pandemics — most policies explicitly exclude this since COVID
- General economic downturns — if work dries up because the market’s quiet, that’s on you
- Supplier delays — if your materials don’t show up, it’s usually not covered
- Voluntary closure — you choose to shut for a holiday, no cover
The Waiting Period
Every policy has a waiting period — usually 48 or 72 hours. That’s the time between the event and when cover starts. You cover the first couple of days yourself. After that, the insurer pays for the period of interruption, up to a maximum (often 12 or 24 months).
Pro tip: Choose a shorter waiting period if you’ve got high overheads. It costs a bit more, but if you’re paying rent and wages, those two days could be thousands out of pocket.
How Much Cover Do You Actually Need?
This is where most tradies get it wrong. They either underinsure or guess. Here’s how to work it out:
Step 1: Calculate Your Gross Profit
Gross profit is your total income minus the cost of materials and subcontractors. For most tradies, that’s around 40-60% of your turnover. If you turnover $200,000 a year and spend $80,000 on materials and subs, your gross profit is $120,000.
Step 2: Add Your Fixed Overheads
These are expenses that keep running even when you’re not working:
- Rent or mortgage on your workshop
- Vehicle loan repayments
- Tool and equipment lease payments
- Staff wages (if you employ others)
- Insurance premiums
- Phone, internet, accounting software subscriptions
- Loan interest payments
Step 3: Add Your Profit
You need to cover the profit you’d have made during the downtime. That’s why it’s called loss of profits cover.
Example: A sparky in Melbourne with a $300k turnover, $120k gross profit, and $50k in fixed overheads needs around $170,000 in annual business interruption cover. That works out to about $3,300 per week.
In 2026, most insurers offer cover in increments of $50,000 or $100,000. A policy covering $150,000 to $200,000 will cost a tradie like that between $1,000 and $2,500 per year, depending on their trade and claims history.
State-by-State Considerations
- NSW: Insurers here often require you to nominate a specific sum insured. Don’t guess — get your accountant to help calculate it.
- VIC: Some policies include automatic indexation to keep up with inflation. Worth asking about.
- QLD: With cyclone and flood risks, premiums can be higher. Insurers may also impose longer waiting periods for storm events.
- WA: Remote tradies in mining towns might pay more due to limited insurer appetite.
- SA, TAS, ACT, NT: Generally lower premiums, but check for specific exclusions around bushfire or flood zones.
What’s the Claims Process Like?
If the worst happens, here’s what you need to do:
- Notify your insurer immediately — within 24-48 hours usually
- Mitigate your loss — do what you can to minimise downtime (e.g., hire a temporary workshop)
- Keep records — save receipts, invoices, and a log of jobs you had to cancel
- Provide proof of income — your last two years of tax returns, BAS statements, and profit & loss reports
- Wait for assessment — the insurer will send an assessor to confirm the event and calculate the interruption period
Most claims are paid within 2-4 weeks after assessment. Some insurers offer an interim payment if you’re in financial distress.
Heads up: If you’re a sole trader, the claim is usually straightforward. If you have employees, expect more paperwork — the insurer will want proof you’re paying wages or have stood staff down properly.
Platforms like BizCover let you compare quotes from multiple insurers, so you can see who offers the best claims support and waiting periods. That’s useful because claims experience varies wildly between insurers.
Common Traps Tradies Fall Into
I’ve seen blokes buy business interruption cover and still get caught out. Here are the five biggest traps:
1. Underinsuring Your Sum Insured
If you insure $100,000 but your actual loss is $150,000, the insurer will only pay the $100,000 — and they might apply the “average” clause. That means they only pay a proportion of your claim. You lose twice.
Fix: Get your accountant to calculate your gross profit and overheads properly. Update it every year.
2. Forgetting the Waiting Period
You choose a 72-hour waiting period. Your workshop burns down on a Friday. You can’t start work until Wednesday. That’s five days of downtime, but you only get covered for two of them.
Fix: Choose a 24 or 48-hour waiting period if you can’t afford two days off.
3. Not Covering Your Employees
If you have staff, their wages are a fixed overhead. If you don’t include them in your sum insured, you’ll have to pay them out of your own pocket while you’re not earning.
Fix: Include total wages in your overheads calculation.
4. Assuming It Covers You for Illness
Business interruption is for property damage, not personal injury. If you break your leg, you need income protection insurance — a different product entirely.
Fix: If you’re a sole trader, income protection is arguably more important than business interruption. Get both if you can.
5. Not Reading the Exclusions
Some policies exclude loss of utilities, supplier failure, or damage to leased equipment. Others only cover you for 12 months, even if your rebuild takes 18.
Fix: Read the product disclosure statement (PDS). If you don’t have time, ask your broker or use a comparison platform that highlights key exclusions.
FAQ: Business Interruption Insurance for Tradies
Is business interruption insurance tax deductible?
Yes. The premium is considered an insurance expense and is deductible against your business income. Keep the receipt for your accountant.
Do I need it if I work from home?
It depends. If you have a home workshop or store tools at your house, business interruption can cover the loss of use of that space. But your home insurance won’t cover business interruption — you need a separate policy or an add-on.
Can I add it to my existing insurance policy?
Some insurers offer it as an optional add-on to your business pack (which includes public liability and tool cover). Others require a separate policy. Check with your provider.
How long does cover last after an event?
Most policies cover you for up to 12 months from the date of the event. Some offer 24 months for an extra premium. Choose the longer period if your rebuild could take time — like after a major storm or fire.
What if I’m a sole trader with no employees?
You still need it. Your personal income stops when you can’t work. Business interruption covers your lost profit and fixed expenses like your van lease or tool payments.
Does it cover me if my main supplier goes under?
Rarely. Most business interruption policies only cover physical damage to your own premises or equipment. If your supplier has a fire, you’re usually not covered. Look for a policy that includes “supplier extension” if that’s a risk for you.
How do I compare policies?
Use comparison platforms like BizCover to see what different insurers offer for your trade and turnover. Compare waiting periods, maximum cover periods, and exclusions — not just the premium price.
Can I claim if my tools are stolen but I can still work?
No. If you can still trade (even with borrowed tools), business interruption won’t pay. Tool theft is covered under your tools and equipment insurance, not this policy.
The Bottom Line
Business interruption insurance isn’t for everyone. If you’re a sparky with a van and a few hand tools, you might get away with just tool cover and income protection. But if you’ve got a workshop, employees, vehicle loans, or a steady stream of booked jobs, you’re taking a huge risk by not having it.
In 2026, the average tradie claims around $15,000 in business interruption payouts — and that’s just the ones who have it. The blokes who don’t? They’re the ones selling their ute to cover the rent.
Talk to your insurer or jump on a comparison site. Get a quote. Read the fine print. And if you’re not sure what sum to insure for, get your accountant to run the numbers. It’s a small price to pay for knowing you can survive a bad break.
Because in this game, it’s not if something goes wrong. It’s when.
