Indemnity vs liability: what's the difference?
Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-05
The words indemnity and liability get used almost interchangeably in everyday conversation, but in insurance they answer two separate questions. One is about how a policy pays you. The other is about what you are being protected against. Understanding the split makes policy documents far easier to read — and helps you choose cover that actually matches your exposure.
What indemnity means
Indemnity is a foundational principle of general insurance. It means putting you back in the financial position you occupied immediately before the loss — not profiting from it, and not being left out of pocket beyond your excess and any limits.
If a covered event damages a £10,000 asset, an indemnity settlement aims to make good that £10,000 loss (often after deducting wear and tear, and subject to your policy terms). You are compensated for your actual loss rather than a fixed windfall. This is why most business insurance is described as a contract of indemnity.
The word also appears in two other places that cause confusion:
- Indemnity limit — the maximum a policy will pay, for example £1m, £2m or £5m. It caps the indemnity, not the type of risk.
- Professional indemnity (PI) insurance — a specific product that indemnifies you against claims arising from your professional advice, designs or services. Despite the name, PI is fundamentally about your liability to clients for professional negligence.
What liability means
Liability is your legal responsibility to another party. If your business causes injury, property damage or financial loss to someone else — a client, a member of the public, an employee — the law may require you to compensate them. That legal obligation is a liability.
Liability insurance exists to cover those third-party claims. It typically pays the compensation (damages) you are legally required to give, plus defence costs. The main classes of liability cover in the UK are:
- Public liability — claims from members of the public for injury or property damage.
- Employers' liability — claims from staff who are injured or fall ill through work. This cover is a legal requirement for most employers under the Employers' Liability (Compulsory Insurance) Act 1969.
- Product liability — claims caused by a product you supply.
- Professional indemnity — liability for negligent professional advice or services.
So liability is the exposure. Indemnity is the mechanism by which the insurer settles it. A liability policy indemnifies you against your liabilities.

Why "professional indemnity" trips people up
Professional indemnity is the point where the two words collide. It is called indemnity insurance because it indemnifies you — it makes good your loss when a client claims against you. But the thing it protects you from is a liability: your legal responsibility for a negligent report, design, calculation or piece of advice.
For many regulated professions, PI is not optional. Solicitors must hold cover meeting the Solicitors Regulation Authority's minimum terms and conditions; accountants, architects, surveyors and financial advisers face similar requirements from their own bodies. The point is that a professional's biggest risk is often not physical damage but a costly mistake in their work — and PI is the indemnity that answers that liability.

Most commercial policies combine both concepts in a single sentence. A public liability wording, for example, typically says the insurer will indemnify the insured against sums they become legally liable to pay as damages. Read that carefully and you can see the split doing its job: liability defines the trigger, indemnity defines the payout.
This is also why the indemnity limit matters so much on a liability policy. The limit caps how far the insurer will indemnify you, regardless of how large the liability turns out to be. If a claim exceeds your limit, you can be personally exposed for the balance — which is why choosing an appropriate limit for your sector and contracts is a genuine risk decision, not a box-tick. A broker can help you benchmark the right limit against your client contracts and any regulatory minimum.
Common questions
Is indemnity insurance the same as liability insurance?
No. Indemnity describes how a policy compensates you — by restoring your loss. Liability describes what you are covered for — your legal responsibility to others. Professional indemnity insurance happens to do both: it indemnifies you against your professional liabilities.
Does one policy cover both?
Often, yes. A liability policy is a contract of indemnity, so a single wording will indemnify you up to the stated limit against liabilities it covers. Many businesses hold several policies — public liability, employers' liability and professional indemnity — each addressing a different exposure.
Which do I need for my business?
It depends on your risks. If you employ staff you almost certainly need employers' liability by law. If you give professional advice, professional indemnity is usually essential and may be required by your regulator. If the public visits your premises, public liability is sensible. A broker can map your exposures to the right combination.
