Public liability insurance covers your legal liability for bodily injury or property damage to third parties — a customer slipping in your shop, a contractor's ladder cracking a client's glass door. Professional indemnity insurance covers financial loss caused by your professional advice, design or services — a wrong recommendation, a calculation error, a missed deadline that costs the client money. In short: public liability responds to physical harm; professional indemnity responds to bad work.
What each policy actually covers
Public liability (PL) typically covers compensation and legal costs when your business operations cause bodily injury to a third party or damage to their property. It follows your physical footprint: your premises, your staff working at client sites, your events. It does not cover the quality of your professional work.
Professional indemnity (PI) typically covers compensation and legal costs when a client suffers financial loss because of negligence, errors or omissions in your professional services — wrong advice, defective design, breach of professional duty. It follows your expertise, not your premises. It generally won't respond to a slip-and-fall.
Neither policy covers injuries to your own employees — that's what WICA work injury insurance is for.

Who needs which
- Mostly PL: retail shops, F&B outlets, gyms, salons, cleaning companies, logistics operators, event organisers — businesses whose main third-party risk is physical.
- Mostly PI: consultants, accountants, IT and software firms, marketing agencies, corporate secretaries — businesses that sell advice and deliverables, often with little public footfall.
- Both: architects, engineers, interior designers, fit-out and M&E contractors, medical and wellness clinics, real estate agencies — anyone whose work involves both a physical presence and professional judgement.
Neither cover is compulsory by statute in Singapore, but both are frequently required in practice: landlords and mall operators demand PL before handing over premises, main contractors and tenders specify PL limits, and professional bodies in law, accountancy, medicine, real estate and fund management commonly require PI as a condition of practice.
Key differences in how the policies work
Beyond what they cover, the two policies behave differently:
- Trigger basis. PL is usually written on an "occurrence" basis — it covers incidents that happen during the policy period, whenever the claim is made. PI is usually "claims-made" — it covers claims made while the policy is active, which makes continuous cover and retroactive dates important.
- Pricing. Indicatively, PL runs from around S$100–400 a year per S$1 million of cover for low-risk businesses, and PI from around S$300–800 a year for small firms. Actual premiums depend on your business — get quotes.
- Contract wording. Client contracts often specify one or both by name with minimum limits. Match the certificate you buy to the wording you signed.
Frequently asked questions
What is the difference between public liability and professional indemnity insurance?
Public liability covers bodily injury or property damage your business causes to third parties, while professional indemnity covers financial loss caused by your professional advice, designs or services. One responds to physical harm, the other to negligent work — and one cannot substitute for the other.
Do I need both public liability and professional indemnity?
You need both if your business has a physical footprint and sells professional judgement — architects, engineers, interior designers, contractors, clinics and real estate firms typically carry both. A pure advisory firm with no public premises may need only PI; a retail shop may need only PL.
Is public liability insurance compulsory in Singapore?
No, public liability is not legally compulsory in Singapore — but landlords, mall operators, main contractors and government tenders very commonly require it by contract, often at S$1 million or more, so most customer-facing businesses carry it in practice.
Does professional indemnity cover injury to people?
Generally no — bodily injury and property damage are the domain of public liability insurance, and PI policies typically exclude them. The main exception is professions where negligent advice or treatment causes bodily harm, such as medical practice, where specialised indemnity arrangements apply.
Which is more expensive, PL or PI?
For a small low-risk firm, PL is usually cheaper — indicatively from around S$100–400 a year per S$1 million of cover versus around S$300–800 a year for entry-level PI. High-risk trades pay more for PL, and high-exposure professions pay more for PI. Actual premiums depend on your business — compare real quotes.
