September’s Brief Commentary
September's Market Brief: Why Costs Are Rising Even Though Premiums Aren't
I've been reviewing the latest market commentary, and there's a distinction worth making clearly: premiums themselves are fairly stable right now. But if you run a business, don't let that lull you into thinking your costs are staying flat too — because for a lot of businesses, they aren't.
Insurers are tightening natural hazard wording, and putting a lot more emphasis on what's called "defensible sums insured." Neither of those phrases sound like they'd cost you anything. In practice, they often do.
Stable premiums don't mean stable costs
Here's the gap that catches people out: your premium might renew at roughly the same number it did last year. But the requirements attached to keeping that cover in place are getting more specific — and more demanding. Updated valuations. Engineering reports. Hazard-mitigation requirements you didn't need to think about two years ago.
None of that shows up as a line on your premium. It shows up as a bill from a valuer, a report you didn't budget for, or a compliance requirement that lands on your desk with a deadline attached. Technically, your insurance didn't get more expensive. Practically, running your business just did.
What "defensible sums insured" actually means for you
This phrase is doing a lot of work in the industry at the moment, so it's worth unpacking. A "defensible" sum insured is one an insurer can point to and say: this number was arrived at properly, with real evidence behind it — not just last year's figure with a bit added on.
Insurers are asking for that evidence more often now. Which means the businesses that get caught out aren't usually the ones who under-insured on purpose — they're the ones who never revisited a number that made sense five years ago and just assumed it still did.
Where a broker actually earns their keep
This is the part of my job that doesn't show up in a policy document, but matters more than almost anything else I do: planning ahead so none of this blindsides you.
In practice, that looks like:
Timing building valuations properly — not scrambling for one after an insurer asks, but having it done on a schedule that keeps you defensible year-round.
Reviewing your risk management practices before an insurer flags a gap, not after.
Using insurer-funded services that already exist — NZI, for example, offers electrical checks and fire protection assessments as part of some policies. Most business owners never ask for them, simply because nobody told them they were available. That's a cost an insurer is already willing to absorb, and it's a genuine waste not to use it.
None of this is complicated. It just requires someone to actually be looking ahead on your behalf, rather than reappearing once a year at renewal.
The small stuff that keeps insurers comfortable
A lot of what protects you here isn't dramatic. It's routine.
Making maintenance and repairs a visible part of your risk mitigation plan — not just something you do, but something you can point to — tells an insurer you're actively managing risk rather than hoping nothing goes wrong. The same goes for regularly servicing plant and equipment to reduce the chance of a machinery breakdown claim in the first place.
These aren't big-ticket items. But they're exactly the kind of evidence that keeps an insurer comfortable with your file — and comfortable insurers are far less likely to push back at renewal, or add conditions you'd rather not deal with.
My role in all of this
For SMEs and growing businesses especially, this is where I spend most of my actual time: not just placing a policy once a year, but helping you stay ahead of changes like these so they don't turn into surprises. The goal isn't more paperwork for its own sake — it's making sure you're never paying for compliance you could have avoided, or scrambling for a report you had months of notice to arrange.
If any of this sounds like it might already apply to your business — an outdated valuation, a sum insured nobody's revisited in a while, or an insurer-funded service you didn't know you had access to — that's exactly the kind of conversation worth having before renewal, not during it.
