Do I need public liability insurance in the UK? The honest answer is that no single law decides it for every business, while contracts, licences and councils often do. This guide shows where each kind of requirement comes from, compares six published examples with their dates, and gives a five step route to your own answer. We explain, we do not advise, and we checked the pages on 3 November 2026.
Quick answer
No UK law makes public liability insurance compulsory for every business, but employers' liability is required once you employ staff. Councils, clients and licences set their own limits, often £5 million or £10 million.

| What is compulsory? | Employers' liability once you employ anyone |
| Who sets other requirements? | Councils, clients, venues and licence conditions |
| Typical council figure | £5 million or £10 million in the examples we read |
| Is the basis stated? | Sometimes, such as per claim |
| Where do I check my answer? | Your contract, licence or tender document |

Do I Need Public Liability Insurance by Law? One Compulsory Cover
The only liability policy we found that gov.uk makes compulsory is employers' liability. The page says you need it as soon as you become an employer, with cover of at least £5 million from an authorised insurer. It also says you can be fined £2,500 every day you are not properly insured and £1,000 if you fail to display the certificate. You do not need it if you employ only close family members or people based outside England, Scotland and Wales.
Public liability is not on that page. HSE Northern Ireland says the cover is voluntary and that you can choose the limit. A West Sussex County Council guide says it is not currently a legal requirement but may be needed depending on your business type, sector or activities. The so what: your first legal question is whether you employ people. Your public liability question starts with whoever you work for or with. Our hub guide explains how the three main covers fit together.
Where Public Liability Requirements Come From
When you ask "do I need public liability insurance for this job?", start by finding who controls the work. Requirements come from a small number of places. The table lists them with an example from the pages we opened. Each example is one organisation's rule and not a national standard.
| Source of requirement | Example we found | Figure |
|---|---|---|
| Council tender | East Sussex County Council | £10 million for each claim as standard |
| Council partners | West Sussex County Council | £10 million for organisations working with it |
| Council events | Sandwell | £5 million per claim |
| Street trading licence | Islington | £5 million minimum |
| Highway scaffolding licence | Medway | £5 million minimum |
| Contractor on school sites | Staffordshire County Council | £5 million public liability |
Look at the pattern, not the numbers. The requirement belongs to the body that controls the work: the contracting authority, the licensing authority or the event organiser. A private client can ask for anything, so a figure in your own contract overrides any table. Our 10 million guide covers the high end of this list.
How Old Are These Sources?
A requirement page is only as good as its date. We worked out the age of each dated page in the table from the page dates the councils show. The calculation is ours.
| Page | Page date shown | Age at 3 November 2026 (our arithmetic) |
|---|---|---|
| Medway scaffolding policy | 10 December 2019 | About 7 years |
| Islington street trading | 22 July 2022 | About 4 years |
| Sandwell events | 5 May 2023 | About 3 years and 6 months |
| East Sussex, West Sussex and Staffordshire | No date shown | Unknown |
Three of the six pages are over two years old and three are undated, so every figure here needs re-checking before you rely on it. The so what: use these as examples of the kinds of figure councils ask for, and get the live figure from the body that is asking you. A page from 2019 may have changed twice.
Contractors, Clients and Tenders
Public sector buyers often set a standard and then adjust it. East Sussex says its standard requirement is £10 million for each claim, which it may reduce to £5 million for lower-risk activities and to £2 million where it sees virtually no risk. The requirement applies to contracts whether they are above or below its tender threshold. Staffordshire sets a different pair for contractors: at least £5 million of public liability and at least £10 million of employers' liability, kept in force continuously.
Notice what the Staffordshire page does. It asks for £10 million of employers' liability, which is above the £5 million minimum on the gov.uk page. The law sets a floor, and a client can set a higher bar. Our construction guide looks at how this works down a chain of contractors.
Picture a small decorator who is asked to repaint a school building on a framework. The decorator reads the council's contractor page, sees public liability of £5 million and employers' liability of £10 million, and checks the policy schedule for both numbers before sending a quote. Nobody in the story was told to buy anything. The decorator simply compared two documents.
Licences and Events That Ask for Public Liability Insurance
Licences work differently from tenders because the condition attaches to your permission to operate. Islington says street traders need cover of at least £5 million for the duration of the licence, and that trading without valid insurance can lead to suspension or revocation. Medway says scaffolding and hoarding licence holders must have public liability insurance, not employers' liability, for a minimum of £5 million, and warns that insurance may be void if the scaffold on the highway lacks a valid licence.
Events add an organiser layer. Sandwell says every event in its area must be covered by a minimum of £5 million per claim, that some high-risk activities may need more, and that organisers should ask each provider to hold the same level. The so what: if you supply an event, your client may ask for the same limit as the council does. Our what is it guide explains what a limit is.
Do I Need Public Liability Insurance? A Five Step Route to Your Answer
If you want a fixed method for the question do I need public liability insurance, use this order. Each step ends with a document you can read.
- Do you employ anyone? If yes, check employers' liability on gov.uk first.
- Is your profession regulated? If yes, check your regulator's rules on professional indemnity.
- Does your licence or permit name an insurance condition? Read the conditions.
- Does the contract, lease or tender name a limit and a basis? Read the clause.
- Does your policy schedule match that limit and basis, and do the dates cover the work?
Our professional indemnity guide covers step two. For professions with a regulator, the SRA says the minimum is at least £3 million for some bodies and at least £2 million in other cases, which shows that regulators set their own figures too.
Reading the Wording of a Requirement
The same limit can mean different things depending on the words around it. The table collects phrases from the pages above and the question each one raises. Nothing here is advice, because only the clause in your own document counts.
| Phrase we saw | Where | Question to ask |
|---|---|---|
| "Per claim" | Sandwell | Does my policy limit apply to each claim? |
| "For each claim" | East Sussex | Same question, different council |
| "For the duration of your licence" | Islington | Do my policy dates cover the whole licence period? |
| "Not employer's liability" | Medway | Am I showing the right policy? |
| "Kept in force continuously" | Staffordshire | What happens at renewal? |
The last row is the one that catches people. A policy that lapses for a week between renewal dates can break a continuous requirement, even if it was valid the week before and the week after. The so what: when you ask whether you need public liability insurance for a given job, also ask when the proof must be shown, and for what dates.
A Requirement Tracker You Can Copy
Keep one row for every job, licence or lease that asks for cover. The columns match the checks above, and the example row uses invented figures to show the format.
| Document | Figure asked for | Basis | Dates it must cover | Evidence I hold |
|---|---|---|---|---|
| Example event agreement | £5 million | Per claim | Event day and set-up | Certificate dated this month |
Fill the row from the document, not from memory. If you cannot fill a cell, that cell is your next question to the client or the insurer. A tracker also shows quickly whether one policy can meet several requirements at the same time, which is a different question from whether you need public liability insurance at all.
What We Could Not Confirm
We did not find a single UK-wide page listing every business that must hold public liability. We did not check Scottish or Welsh licensing rules, and our council examples come from English authorities. We also could not tell from the undated pages whether their figures have changed. These are gaps in what we could verify, and they are the reason we link to each source on the words it supports.
What Is Moving Into 2027
| Item | What we found | Why it matters |
|---|---|---|
| Product liability law | A Law Commission consultation runs until 14 January 2027 | Contracts for goods may refer to changed rules later |
| Council pages | Several are undated or old | Re-check each requirement at the next renewal |

Frequently Asked Questions
Do I need public liability insurance in the UK? No single law requires it for every business. HSE Northern Ireland calls it voluntary, and contracts, licences and councils may still require it. Check the document that asks for your work.
Is employers' liability insurance compulsory? Yes, once you employ staff. Gov.uk says you need at least £5 million of cover, and fines run to £2,500 for every day you are not properly insured.
What limit do councils ask for? The examples we found range from £2 million for virtually no risk to £10 million as the standard, with £5 million common for licences and events. Your own contract sets the figure that matters.
Do I need public liability insurance as a sole trader? No law requires it, but clients and licences may. Our sole trader guide explains why a claim can reach personal assets. A sole trader with no employees does not need employers' liability.
Do I need it to work from home? We did not find a gov.uk page that requires it. If customers visit, or a client asks for proof, the requirement comes from that relationship. Check any lease or client agreement.
Do I need it to run a market stall? Licence conditions may require it. Islington's street trading condition sets a £5 million minimum for the licence period. Check your own council.
Does the Insurance Act 2015 matter here? Yes, once you buy. The Act applies to non-consumer contracts and requires a fair presentation of the risk before the contract starts.
How does Cairn Cover help? We read government and council pages, date them, and link them on the words they support. We do not sell insurance, quote prices or recommend a limit.
