Public indemnity insurance is not a product sold in the United Kingdom. The phrase blends the names of two real and quite different policies: public liability, which answers for physical harm to other people, and professional indemnity, which answers for money somebody lost because of your work. Anybody searching for the blended name usually needs one of the two and sometimes both, and buying the wrong one is an expensive way to find out which.
Public liability: injury and damage
Public liability answers for your legal liability to a third party for bodily injury or damage to their property arising from the business, and it pays the defence costs. It is the cover a landlord, a venue, a site or a commercial customer asks to see, usually naming one, two or five million pounds. If the harm you might cause is physical, this is the policy, and no statute makes it compulsory.
Professional indemnity: financial loss
Professional indemnity answers for a client's financial loss caused by a negligent act, error or omission in your professional work, and it funds the defence. Nobody is hurt and nothing is broken; the loss is money. It is written on a claims made basis, which means the policy that answers is the one in force when the claim is made rather than when the work was done, so it has to outlive the engagement.
Which one you need, decided by one question
Ask what a dissatisfied person would be claiming for. A tripped visitor, a scratched floor or a damaged machine is public liability. A lost fee, a penalty, a project that had to be redone or a decision taken on bad advice is professional indemnity. Trades that advise as well as work, such as electricians who certify or designers who specify, genuinely need both, and their client contracts usually say so.
Why the blended name persists
Both policies are sold on the same schedule by the same brokers, both are described as liability cover, and the word indemnity appears in general insurance language for any promise to make good a loss. That is enough for the names to run together. Using the right one when you ask for a quote avoids the commonest outcome, which is a certificate that satisfies nobody's requirement because it names the wrong section.
Questions people ask about public indemnity insurance
What is public indemnity insurance?
It is not a UK policy name. It blends public liability, which answers for injury and property damage, with professional indemnity, which answers for a client's financial loss from negligent work.
Which do I need, public liability or professional indemnity?
Ask what somebody would be claiming for. Physical injury or damage is public liability; money lost because of your advice or work is professional indemnity. Businesses that both work and advise often need both.
Can I buy them on one policy?
Yes, most UK insurers put both sections on one schedule with separate limits, which is usually cheaper and avoids a gap between two insurers each assuming the other covers something.
Is either one compulsory?
Neither is required by general statute. Professional indemnity is required by some regulators and by most corporate contracts; public liability is required by landlords, sites and commercial customers. Employers' liability is the one the law compels.
