What is plumbers’ insurance?
No matter how careful you are, plumbing work does involve risks like slips, falls, injuries, lost tools or even damage to a client’s property.
That’s where business insurance for plumbers comes into play. Plumbers’ insurance (shorthand for the types of insurance for residential and commercial plumbers you might consider) helps protect your plumbing business against a variety of risks, ensuring your operations can continue smoothly despite unforeseen events.
Business insurance might be a requirement to operate as a plumber in certain regions. For instance, plumbers’ insurance in Victoria is required for residential and commercial plumbers. You must hold minimum levels of public liability insurance to work in the state.

Why do plumbers need insurance?
Plumbers may need business insurance to meet legal and contractual obligations, as well as to cover unexpected bills.

Unsure how much to choose? Think about:
Underinsurance
We know it’s tempting to select a lower level of cover to reduce premiums, but this can leave businesses shocked and insufficiently covered when making a claim.
Ways underinsurance catches business owners out:
Inflation
With inflation, the cost of living and doing business increases. Remember to cover you, your tools and assets for the rising costs of replacing or covering them, not what you paid for them – you may be surprised at the difference.
Not covering the full cost of your risks
If you select cover levels for less than the value you may be found liable – left out of pocket when it comes to claims time. It’s important to review your risks and determine how much you will need to cover any claim that may come your way.

Frequently asked questions
Depending on your needs, you might consider different types of insurance to protect your plumbing business. These may include:
