Professional Indemnity Insurance
When your advice or work goes wrong, and the client blames you
You delivered the work. They’re unhappy with the outcome. Now they’re claiming your advice, service, or design caused them financial loss. Professional Indemnity protects you from the lawsuits that could destroy your business.

What could go wrong
(and why you need this)
If you give advice, deliver professional services, or create work that clients rely on, you need Professional Indemnity cover. Here’s what it protects you from:
Scenario 1
The design that "cost them sales"
You run a 5-person branding agency. You design a client’s new website and brand identity. They launch, sales are lower than expected, and they blame your design.
They claim your work cost them $120,000* in projected revenue and want compensation. They sue.
What Professional Indemnity covers
Your legal defence costs, expert witness fees to prove your work was professional, and any settlement if the court finds you partly liable.
Scenario 2
The advice that didn't work out
You’re a business consultant. You advised a client to restructure their operations.
They followed your advice, but market conditions changed, and they incurred a loss. Now they’re claiming your advice was negligent and caused $200,000* in losses.
What Professional Indemnity covers
Your legal representation, investigation costs to prove your advice was reasonable at the time, and compensation if you’re found liable for professional negligence.
Scenario 3
The missed deadline
You’re a solo marketing consultant. A client hired you to launch their product campaign by a specific date.
You delivered 3 weeks late due to scope creep and miscommunication. They claim the delay cost them $80,000* in missed sales during peak season.
What Professional Indemnity covers
Your legal defence, costs to prove the delay wasn’t solely your fault, and settlement payments if you’re found to have breached your professional duty.
Scenario 4
The confidentiality breach
You’re a software developer. During a project, you accidentally exposed some of the client’s proprietary code in a public GitHub repository for 48 hours before you noticed.
They claim their competitor saw it, and their competitive advantage is gone. They’re suing for $500,000*.
What Professional Indemnity covers
Your legal costs, forensic investigation to determine actual damage, and compensation for the breach of confidentiality.
What this actually covers
Professonal indemnity
Professional Indemnity protects you when:
- A client claims your advice, service, or work caused them financial loss
- You make a mistake or error in your professional service
- You miss a deadline, and the client suffers losses as a result
- You breach confidentiality or disclose client information accidentally
- Someone claims your work infringed their intellectual property
- A client alleges you were negligent in your professional duty
What's typically covered:
- Legal defence costs (this is usually the biggest expense)
- Court costs and settlements
- Compensation payments for client losses
- Cost of correcting your work or redoing the project
- Investigation costs and expert witnesses
- Your legal representation if sued
Important: "Claims made" vs. "claims occurring"
Professional Indemnity is “claims made” cover—meaning you need insurance in place when the claim is made, not when the work was done. If you let your policy lapse, you will not be covered for any past work. This is crucial to understand.
What's typically not covered
- Bodily injury or property damage (that’s Public Liability)
- Your own business losses or costs
- Intentional wrongdoing or fraud
- Work done before you got insurance (it’s “claims made” cover)
- Criminal acts or illegal services
- Contractual penalties (unless insured separately)
When you need this

Start smart
Pre-launch to first year
You need this from Day 1 if:
- Give advice as part of your service (consultants, coaches, strategists)
- Create work clients rely on (designers, developers, architects, engineers)
- Handle client data or confidential information
- Provide professional services that could cause financial loss if wrong
- Have contracts that require Professional Indemnity cover
Who needs it most:
Consultants, designers, developers, accountants, financial advisers, architects, engineers, marketers, IT service providers, coaches, HR consultants, legal service providers.
Typical coverage
$1-2 million is common for solo operators and small agencies.
Scale strong
Growing and hiring
Your cover needs to increase when:
- Your revenue exceeds $1M (higher turnover = higher potential claims)
- You’re winning larger clients with bigger projects
- Client contracts require higher limits ($5M or $10M)
- You’re taking on more complex or higher-risk projects
- You’re working with government or corporate clients
Typical coverage
$2-5 million for growing businesses. Some contracts require $10M+.
Stay protected
Established and optimising
Review your cover if:
- You’ve changed what you do (new services = new risks)
- You’ve had a near-miss or complaint that didn’t escalate to a claim
- A client has threatened legal action
- Your industry has seen high-profile claims
- You’re moving into new markets or industries
Typical coverage
$10-20 million. Some corporate clients require $20-50 million for larger contracts.
Common questions
Founders actually ask
I haven't been sued before, do I really need this?
Most founders haven’t been sued. That’s not the point. One claim can bankrupt your business. Legal defence alone costs $30-50k even if you win.
A settlement or court judgment could be hundreds of thousands. It only takes one unhappy client.
My contract has a limitation of liability, doesn't that protect me?
Contract clauses help, but they don’t eliminate risk. Courts can override limitations if they’re deemed unfair. Clients can still sue, and you still need to defend yourself.
Professional Indemnity covers your legal costs, even when your contract appears solid.
What if the client is just being unreasonable?
Doesn’t matter. If they claim you caused them loss, they can sue. You’ll need lawyers to defend you.
Professional Indemnity covers your defence costs whether the claim is reasonable or not. The insurer assesses the claim and handles your defence.
I'm a sole trader, can they come after my personal assets?
Yes. If you’re a sole trader or in a partnership, your personal assets (house, savings, car) are at risk if you lose a claim.
Even if you’re a company, directors can be personally liable in some circumstances. Insurance protects you either way.
Does this cover me for work I did before I got insurance?
No. Professional Indemnity is “claims made” cover, you must have insurance at the time the claim is made.
That’s why you can’t let it lapse. If you cancel your policy, you’re not covered for past work. Many policies offer “retroactive cover” for previous work, but you need to ask for it.
How much cover do I actually need?
This depends on your circumstances. However, coverage usually starts at $1-2 million if you’re a solo practitioner or a small agency.
You may need to increase to $5M+ as you grow or if clients contractually require it.
Consider: What’s the biggest project value you work on? What if that went completely wrong? That’s your potential exposure.
