Public liability insurance for small business: what it covers and why clients demand it

Public liability insurance covers injury to people and damage to property caused by your business. Here is what it actually covers, what it excludes, how much cover you need, and why certificates of currency rule your working life.

No law forces most Australian small businesses to hold public liability insurance. Yet try to win a cleaning contract, install a floor in a shopping centre, run a market stall or sign a commercial lease without it. Public liability is the cover the market makes compulsory — and the paperwork that proves it, the certificate of currency, runs more of your working life than the policy itself.

What public liability actually covers

Public liability covers your legal liability to other people — customers, clients, suppliers, passers-by — for two things arising from your business activities:

  • Personal injury. A customer slips on a wet floor in your cafe. A visitor trips over your extension lead on site.
  • Property damage. Your ladder goes through a client's window. A burst fitting you installed floods the office below.

Crucially, it also pays the legal costs of defending a claim — often the largest part of the bill even when the claim fails. Cover applies wherever the business operates: your premises, a client's site, or in public.

What it does not cover

  • Your own property. Your tools, stock and equipment need business contents or tool cover.
  • Your employees. Staff injuries are workers compensation territory — a separate, compulsory scheme.
  • Bad advice. Financial loss from your professional advice or design is a professional indemnity claim, not a public liability one.
  • Faulty workmanship itself. Policies commonly cover the damage your defective work causes, but not the cost of redoing the work.
  • Excluded activities. Policies are rated on your declared business activities. Work outside them — hot works, heights, asbestos — may not be covered unless declared.

How much cover do you need?

Public liability is sold in standard limits: $5 million, $10 million and $20 million. The honest answer to "how much do I need" is usually "whatever your contracts say". Commercial clients, shopping centres, government tenders and construction sites routinely specify $10 million or $20 million as a minimum, and a certificate showing less means you do not start work. The premium difference between $10 million and $20 million is often smaller than people expect, because most claims are far below the limit.

Before renewing, skim the insurance clauses of your two or three biggest client contracts. If a contract demands $20 million and your certificate says $10 million, that mismatch usually surfaces at the worst possible time — during onboarding for a job you have already priced.

The certificate of currency treadmill

The policy gets used rarely; the certificate of currency gets used constantly. Every new client, site induction, lease renewal and tender wants proof of current cover — the insurer-issued certificate showing your business name, cover limit and expiry date. And because certificates expire with the policy, every renewal quietly invalidates the copy your clients have on file, triggering a fresh round of requests.

Most small businesses handle this by email archaeology: someone searches their inbox for the certificate the broker sent months ago, hopes it is the current one, and forwards it on. When that person is on leave, the job waits.

A better system: one vault, current documents

This is a filing problem, and it has a filing solution. In Insuro, your business is an entity and every policy lives against it:

  • File the public liability policy schedule and its current certificate of currency against your business entity, alongside PI, business pack and vehicle policies.
  • When the insurer or broker emails a renewal or an updated certificate, forward it to your private @insuro.com.au address and it is filed against the right policy automatically — the current certificate is always the one on top.
  • Renewal reminders fire before expiry, with enough lead time to re-quote and to check your cover limit still matches what your contracts demand.
  • Anyone on the team can pull up the current certificate in seconds when a site manager asks — no inbox archaeology, no waiting for the office manager to get back from leave.

The bottom line

Public liability is the cheapest insurance relative to the size of the disaster it prevents — a single injury claim can run to hundreds of thousands of dollars in damages and legal costs. Hold a limit that matches your contracts, declare your activities honestly, never let it lapse between renewals, and keep the certificate where your whole team can find it. The policy protects the business; the system around it protects your week.

Frequently asked questions

Is public liability insurance compulsory in Australia?⌄

For most businesses, no law requires it. But it is effectively mandatory in practice: commercial contracts, site inductions, trade licences in some states, and most commercial leases require current public liability cover before you can work.

What does public liability insurance actually cover?⌄

It covers your legal liability for injury to third parties and damage to their property arising from your business activities — plus the legal costs of defending a claim. It does not cover your own property, your employees' injuries, or claims arising from professional advice.

How much does public liability insurance cost for a small business?⌄

Premiums vary widely with industry risk, turnover and cover limit. A low-risk consultant might pay a few hundred dollars a year for $10 million of cover, while trades and hospitality businesses commonly pay from several hundred to a few thousand dollars.

What is a certificate of currency and why do clients keep asking for one?⌄

A certificate of currency is the insurer-issued document proving your policy is active, showing the insured name, cover limit and expiry date. Clients and site managers ask for it because they carry the risk of letting an uninsured contractor on site. Keeping the current certificate somewhere the whole team can find it — like an Insuro vault — turns an urgent scramble into a ten-second task.
