## Key takeaways

- Business insurance protects a business from the financial cost of things going wrong — injury, damage, claims, losses and more.
- Employers' liability insurance is a legal requirement in the UK for most businesses that have staff.
- Public liability covers claims from third parties; professional indemnity covers claims arising from your advice or work.
- Other common covers include property, business interruption, product liability, cyber and professional vehicle insurance.
- What you need depends on your activities, sector and obligations — this is general information, not insurance or legal advice.

Running a business means taking risks — but some risks can sink you. A customer trips and is injured on your premises. An employee develops a work-related illness. A client claims your advice cost them money. A fire shuts your shop for a month. Business insurance exists to stop events like these from becoming financial catastrophes, by transferring the cost of certain things going wrong to an insurer in exchange for a premium. This guide explains the main types of cover, what each protects against, and when insurance is legally required in the UK.

*This article is general information about business insurance, not insurance or legal advice. The cover you need depends on your specific circumstances — check your sector's rules and consider professional or broker advice.*

## What business insurance is

**Business insurance is a set of policies that protect a business against the financial impact of risks such as injury claims, property damage, legal action, theft and interruption to trading.** Instead of bearing the full cost of a disaster yourself, you pay a regular premium and the insurer covers eligible losses up to the policy limits.

There is no single "business insurance" product. Instead there are many types of cover, each aimed at a particular risk, and a business chooses the combination that fits its activities. A freelance consultant, a high-street café and a manufacturer face very different risks and so need very different policies.

The right way to think about it is by asking: *what could go wrong, how badly would it hurt, and which of those risks should I transfer to an insurer?* Some cover is legally required; much of the rest is a judgement about how much risk you can afford to carry yourself.

## Employers' liability: the legal requirement

The most important point about UK business insurance is this: **if you employ staff, you are generally required by law to hold employers' liability insurance.**

Employers' liability cover protects against claims from your own employees who are injured or become ill as a result of their work. The law requires most employers to hold at least a minimum level of cover from an authorised insurer, and to display or make available the certificate. There are limited exceptions — for example, some businesses employing only close family members, or sole traders with no employees — but the default position is that having staff means needing this cover.

This is not optional in the way most insurance is. Failing to hold required employers' liability insurance can lead to significant penalties. The rules are set out on GOV.UK, and the Health and Safety Executive (HSE) oversees workplace health and safety more broadly. If you are taking on your first employee, treat sorting this cover as part of the same process as registering as an employer.

> If you have employees, start with employers' liability — it is usually a legal duty, not a choice. Everything else is risk management on top.

## Public liability and product liability

**Public liability insurance** covers claims made by *third parties* — customers, clients, suppliers or members of the public — who suffer injury or property damage connected to your business. Classic examples: a visitor slips on a wet floor in your premises, or you damage a client's property while working at their site.

Public liability is not legally required for most businesses, but it is widely held because the risk is so common and the potential costs so high. Many clients, landlords and venues will also insist you have it before they do business with you.

**Product liability insurance** is closely related and covers claims that a product you supplied caused injury or damage. If your business makes, sells or supplies physical products, this addresses the risk that one of them harms someone. The two are often bought together where relevant.

## Professional indemnity and other key covers

If your business gives advice, designs things, or provides a professional service, **professional indemnity (PI) insurance** is often the most important cover of all. It protects against claims that your advice was negligent, that you made a mistake, or that your work caused a client financial loss — covering legal defence costs and any compensation.

PI is standard for consultants, accountants, solicitors, architects, designers, IT professionals and many others. For some regulated professions it is *mandatory*, required by the relevant professional body or regulator. Even where it is optional, clients frequently require it in contracts.

Beyond these, several other covers are common depending on the business:

| Cover | What it protects against |
|-------|--------------------------|
| Property / contents | Damage to or loss of your premises, stock, equipment and contents (fire, flood, theft) |
| Business interruption | Lost income while you cannot trade normally after an insured event |
| Cyber insurance | Costs of data breaches, cyber attacks and related liabilities |
| Motor (commercial) | Vehicles used for business — legally required to drive on the road |
| Stock and goods in transit | Loss or damage to goods being stored or moved |

Which of these matter depends entirely on what you do. A digital agency might prioritise professional indemnity and cyber cover; a shop will care more about property, public liability and business interruption.

## When you need cover — and how much

The honest answer to "what insurance do I need?" is: *it depends*. A short framework helps:

1. **Start with the legal minimums.** If you have employees, you almost certainly need employers' liability. If you use vehicles on the road, you need motor insurance. If your profession requires PI, you must hold it.
2. **Look at your contracts.** Clients, landlords and partners often require specific cover — commonly public liability and professional indemnity — as a condition of working with you.
3. **Assess your real risks.** What could plausibly go wrong in your line of work, and how badly would each event hurt? Cover the things that could be serious or business-ending; you can often live with small, affordable risks.
4. **Match the level to the exposure.** Cover limits should reflect the scale of claims you could realistically face, not just the cheapest option.

Insurance sits alongside your other financial planning. Premiums are a running cost that affects [cash flow](/business/cash-flow-management-small-business), so factor them into your budgeting, and remember they are one of the recurring outgoings worth reviewing when you think about [working capital](/business/what-is-working-capital). For sole traders and small firms weighing what is required, the structure of your business — and your obligations — will differ depending on whether you operate as a [sole trader or a limited company](/business/sole-trader-vs-limited-company), so it is worth checking the rules that apply to you and, for anything material, taking advice from a qualified broker or adviser.

## The bottom line

Business insurance turns potentially ruinous events into manageable ones by transferring risk to an insurer. The non-negotiable starting point in the UK is employers' liability insurance if you have staff; from there, public liability protects you against third-party claims, professional indemnity against claims arising from your advice or work, and a range of other covers against property damage, interruption, cyber risk and more. What you actually need depends on your activities, sector and contracts — so identify your real risks, meet your legal duties, and, because this is general information rather than advice, get professional guidance for the cover that fits your business.

## Frequently asked questions

### What business insurance is legally required in the UK?

The main legal requirement is employers' liability insurance, which most businesses with employees must hold (with limited exceptions). Some regulated professions are also required by their regulator to carry professional indemnity cover, and any business using vehicles on the road needs motor insurance. Beyond these, most cover is optional but often advisable. This is general information, not legal advice.

### What is the difference between public and employers' liability?

Public liability covers claims from third parties — such as a customer or member of the public injured, or whose property is damaged, because of your business. Employers' liability covers claims from your own employees who are injured or made ill through their work. They protect against different risks, and many businesses need both.

### Do sole traders need business insurance?

It depends on what you do. A sole trader with no employees is not required to hold employers' liability insurance, but may still want public liability or professional indemnity depending on their work, and any contracts or clients may require specific cover. Always check your sector's rules and your own risk exposure.

### What is professional indemnity insurance?

Professional indemnity (PI) covers the cost of claims that you gave negligent advice, made a mistake, or your professional work caused a client a loss. It is common — and sometimes mandatory — for consultants, accountants, designers, architects and other advisory or service professions. It can cover legal costs and compensation.
