Public indemnity insurance is a phrase many UK readers type when they mean public liability, professional indemnity, or both. This guide shows what we found when we looked for the term on insurer pages, which covers it usually stands for, who needs each one, and how pricing works. We checked the pages on 4 November 2026. We explain and do not recommend a policy.
Quick answer
Public indemnity insurance is not a policy name we found on the insurer pages we opened. People usually mean public liability, professional indemnity, or both. Ask the seller which sections your quote actually contains.

What Public Indemnity Insurance Means in the UK
We looked for the phrase on four pages. Simply Business, on a page last updated on 28 October 2026, does not use it. Markel, on a page dated 12 November 2025, does not use it either. A Hiscox page with no date and a University of Manchester page with no date also speak only of public liability and professional indemnity.
Four pages are a small sample, and we make no claim about the whole market. The finding is still useful. A quote or a contract that says "public indemnity" may be using a loose label, so the words on the page tell you less than the section headings in the policy. The so what: do not buy or accept a requirement on the phrase alone. Ask which defined covers sit behind it.
Four Things the Phrase Public Indemnity Can Mean
The phrase is a blend of two real cover names. Public liability takes "public", and professional indemnity takes "indemnity". Contracts add a third and fourth idea, so the table lists all four.
| What the phrase may mean | Cover that matches | What it deals with |
|---|---|---|
| Harm to a member of the public | Public liability | Injury or property damage, such as a slip or a broken window |
| A client's loss from your advice or work | Professional indemnity | Professional negligence, errors and poor advice |
| A promise to reimburse a client | A contract indemnity | A clause in the contract, not a policy |
| Cover that extends to your client | Indemnity to principals | An extension inside a policy |
The third row is the one that surprises people. An indemnity in a contract is a promise to reimburse someone, and insurance is one way to fund that promise. The two are not the same thing, so a tender that asks you to "indemnify" the buyer may be asking for a contract term, a policy extension, or both. Our what is it guide owns the plain definition of public liability.
Public Liability and Professional Indemnity Side by Side
The two real covers answer different questions. Simply Business says public liability applies if you are sued by a member of the public for injury or damage, while professional indemnity applies if you are sued by a client for a mistake in your work. Markel adds that professional indemnity responds to claims about errors, defamation or libel and poor advice, and that public liability responds to claims by customers, clients, suppliers or passers-by.
Picture a freelance interior designer who visits a client's home. If a tool bag knocks over a vase, that is a damage question. If the design drawings contain an error that costs the client money, that is an advice question. The same person, the same job, and two different covers. Our professional indemnity guide owns the regulator minimums and the sorting table, so we do not repeat them here.
Indemnity to Principals and Contract Wording
Contract wording is where "indemnity" gets a precise meaning. The Designing Buildings wiki, on a page last edited on 6 October 2020, describes indemnity to principals as a provision that gives cover to the client, the principal, if the contractor's negligence leads to a claim against the client. It says a construction contract may require it, and that a contractor should check with the insurer that the policy includes it for the project type. The page is over two years old, so confirm the current position.
A government model schedule shows the same idea in a template. Version 1.0 of the Joint Schedule 3, shown with Crown copyright 2025 and no publication date, asks for professional indemnity, public liability and employers' liability, and requires its public and products liability policy to include an indemnity to principals clause. We did not find a definition of that clause in the schedule. The step is to ask your seller what the clause means for you before you sign.
Who Needs Public Indemnity Cover?
No rule we found makes the phrase itself a requirement. The needs come from three places, and the table sorts them by source.
| Situation | What the sources point to | Where the duty comes from |
|---|---|---|
| You employ staff | Employers' liability, at least £5 million | Gov.uk, a legal duty |
| You belong to a regulated profession | Professional indemnity at the regulator's minimum | The regulator, covered in our PI guide |
| You sign a client or council contract | Whatever the clause names | The contract |
| You work with the public and no one requires it | Public liability, by choice | Hiscox lists employers' liability as the only cover it says businesses may be legally obliged to hold |
The last row is a commercial page, and it agrees with the gov.uk position on employers' liability. A gap between what a label suggests and what a schedule lists is the main risk with a loose phrase, because the schedule is the document an insurer relies on when a claim arrives. For a sole trader with no staff, our sole trader guide covers how personal liability works. Our requirements guide covers the contracts that ask for cover. The so what: write down which of the three sources applies to you, because each one points to a different document.
Public Indemnity Insurance Cost: What Moves the Premium
The cost depends on which cover is meant, so we publish no price. What we can do is set the pricing factors from two Markel pages side by side. The public liability page is dated 8 June 2024, and the professional indemnity page is dated 9 December 2024. Both are commercial pages.
| Factor | Public liability page | Professional indemnity page |
|---|---|---|
| Amount of cover | Named as the main driver | Higher limits generally cost more |
| Type of work | Some industries carry more risk | Some industries are seen as riskier |
| Turnover | Higher turnover may suggest more exposure | Higher turnover may mean more costly contracts |
| Claims history | Past claims can make a business look riskier | Past claims or disputes may raise premiums |
| Premises and footfall | Busy premises may raise the price | Not listed |
| Experience and qualifications | Not listed | Insurers may consider them |
On our reading, five of the six factors apply to both covers, which is why a bundled quote can look similar to a single-cover one. The two columns differ where the risk differs: footfall matters for injury, and experience matters for advice. Our cost guide owns the public liability factors in full. The way to test any claim is to ask for a quote for each cover on the same business description.
Reading a Quote That Uses the Phrase
When a seller or a contract says "public indemnity", you can turn the label into questions. The list below is ours and does not tell you what to buy.
- Which sections does the schedule list, and what is each called?
- Is there a separate limit for each section, or one shared limit?
- Does the business description include advice, design or supervision work?
- Does the contract ask for an indemnity to principals extension?
- Is the limit written per claim, per event or in the aggregate?
Say a landscaper receives a quote headed "public indemnity" that lists only a public liability section. If the landscaper also draws up planting plans for clients, the label has hidden a gap: the advice side has no section at all. We cannot say how an insurer would treat a claim on those facts, and we do not say the landscaper is covered or uncovered. The step is to spot the mismatch before paying, and to ask the seller to confirm in writing. The second question matters most. A combined policy can share one limit across both covers, and the schedule is the place to see it. Our 10 million guide shows how the basis of a limit changes its meaning. The takeaway is to get the answers in writing before you pay.
Buying, Checking and Complaining
The Insurance Act 2015 duty of fair presentation applies to business contracts. Part 2 of the Act, as enacted, asks you to disclose what you know or ought to know, so describe both the physical and the advisory sides of your work. Check the seller on the FCA Financial Services Register, last updated on 13 February 2026.
If you need to complain, contact the firm first. You can then go to the Financial Ombudsman Service within 6 months of the final response, subject to its size tests.
What We Could Not Confirm
We did not find an official UK page that defines the phrase, and we could not open the FCA Handbook pages on product information documents, which need a browser that runs scripts. Four insurer pages are not the whole market. We have not checked Scotland and Wales separately, and we state no prices.

Frequently Asked Questions
What is public indemnity insurance? It is not a standard policy name on the four insurer pages we opened. People use it for public liability, professional indemnity, or both. Ask the seller which defined covers sit behind the phrase, and read the schedule for the section names.
Is public indemnity the same as public liability? Not exactly. Public liability responds to claims by the public for injury or damage. Someone who says public indemnity may mean that, or may mean professional indemnity, which deals with a mistake in your work.
What does public indemnity cover cost? We publish no prices. Premiums depend on the cover, the amount, the type of work, turnover and claims history, according to Markel's cost page dated 9 December 2024. Ask for a quote for each cover on the same description.
Is public indemnity a legal requirement? We found no rule that makes it one. Gov.uk says employers' liability is compulsory for most employers. Regulators and contracts set other requirements, so check your own documents.
What is indemnity to principals? It is a provision that gives cover to the client if a contractor's negligence leads to a claim against the client, according to a wiki page last edited on 6 October 2020. A contract may require it.
Do I need both public liability and professional indemnity? It depends on your work and your contracts. If you handle people, premises or goods, public liability is relevant. If you give advice or designs, professional indemnity is relevant. Some clients ask for both, so read the contract.
Who do I complain to about a policy? Contact the seller first, then the Financial Ombudsman Service within 6 months of the final response, subject to its size tests. Check the seller on the FCA register before you buy.
