Employers' Liability Insurance — When It Becomes Compulsory

Hiring your first employee is one of the biggest milestones in a small business. It means you've grown beyond what you can handle alone, you've got enough work to justify the cost, and you're ready to take on the responsibility of being an employer.

But with that responsibility comes a legal obligation that many new employers don't know about until someone tells them — or until they get fined. Employers' liability insurance is compulsory in the UK for almost every business that has employees. Not optional. Not "nice to have." Compulsory, with penalties for non-compliance.

In this guide, we'll explain exactly when employers' liability insurance becomes a legal requirement, what it covers, who's exempt, and what happens if you don't have it.

What Is Employers' Liability Insurance?

Employers' liability insurance (EL insurance) covers you if an employee becomes ill or is injured as a result of their work for you. If the employee makes a claim against you, EL insurance pays for:

• Legal defence costs — The cost of defending the claim
• Compensation — Any damages awarded to the employee
• Medical costs — Related to the work-caused illness or injury

The key word is "employee." This is different from public liability insurance, which covers claims from members of the public and clients. Employers' liability specifically covers claims from the people who work for you.

Workplace injuries and illnesses happen more often than you might think, even in apparently low-risk environments. An office worker could develop a repetitive strain injury. A shop assistant could slip on a wet floor. A warehouse worker could injure their back lifting stock. In all of these cases, the employee might have a legitimate claim against the employer if the injury was caused by the working conditions.

When Does It Become Compulsory?

Under the Employers' Liability (Compulsory Insurance) Act 1969, you must have employers' liability insurance as soon as you employ anyone. There's no grace period, no minimum number of employees, and no revenue threshold. One employee is enough to trigger the requirement.

The minimum level of cover required by law is £5 million, though most policies provide £10 million as standard.

You must also display your EL insurance certificate — either physically in your workplace or electronically where employees can access it. Some insurers provide a digital certificate that you can display on your company intranet or shared drive.

Here's where it gets important: the requirement kicks in whenever someone meets the legal definition of an "employee." And that definition is broader than many business owners realise.

Who Counts as an Employee?

For the purposes of employers' liability insurance, an "employee" includes:

• Full-time and part-time staff on a contract of employment
• Temporary workers hired directly by you
• Apprentices and trainees working for your business
• Seasonal workers (even if they only work for a short period)
• Casual workers (people you hire on an ad-hoc basis but who are under your control and direction)

Some grey areas:

Agency workers — If you hire someone through an employment agency, the agency is usually their employer for EL purposes, not you. However, if you exercise significant control over how they work, the line can blur.

Subcontractors — Genuine self-employed subcontractors aren't your employees, so you generally don't need EL insurance for them. But HMRC and the courts look at the reality of the relationship, not just the label. If a "subcontractor" works exclusively for you, follows your instructions, uses your equipment, and can't send a substitute — they might actually be an employee in the eyes of the law.

Volunteers — Pure volunteers who receive no payment don't typically trigger the EL requirement. However, if volunteers receive any form of payment or benefit (even expenses above the actual cost), they might be reclassified as workers.

Family members — If you employ family members (including your spouse), you need EL insurance for them — unless you're a sole trader or partnership and the only employees are close family members who live with you (see exemptions below).

The safest approach is: if someone does work for your business and you're not entirely sure of their employment status, assume you need EL cover. The consequences of getting it wrong are severe.

Who Is Exempt?

There are a few narrow exemptions from the EL requirement:

• Sole traders and partnerships with no employees — If it's just you (or you and your business partner), there's no requirement. But the moment you hire anyone, even part-time, you need cover.
• Sole traders or partners who employ only close family members — If the only people working for you are your spouse, civil partner, or close relatives who live with you, you're exempt. This exemption doesn't apply to limited companies.
• Certain public and local authority bodies — Some government organisations are exempt because they're effectively self-insured.
• Family-only businesses not constituted as limited companies — Limited companies must have EL insurance for all employees, including family members who are directors or employees of the company.

If you're in any doubt about whether you're exempt, the Health and Safety Executive (HSE) website has detailed guidance, or you can ask your insurance broker.

What Happens If You Don't Have It?

The penalties for not having employers' liability insurance when you're required to are significant:

• A fine of up to £2,500 for every day you're uninsured. That's not a one-off penalty — it's a daily accumulation. A month without cover could result in a fine of over £75,000.
• A fine of up to £1,000 for not displaying your certificate (or not making it available to employees).
• Personal liability — Without insurance, you'd be personally responsible for any compensation awarded to an injured employee. Claims can easily run into hundreds of thousands of pounds, or more for serious injuries.
• HSE enforcement — The Health and Safety Executive can inspect your workplace and check your EL insurance. If they find you're not insured, enforcement action follows.

Beyond the legal penalties, not having EL insurance when you need it is simply a reckless gamble with your business and personal finances. A single serious workplace injury could bankrupt an uninsured sole trader.

How Much Does It Cost?

The cost of employers' liability insurance depends on your industry, the number of employees, the nature of the work they do, your turnover, and your claims history. As a rough guide:

• Office-based businesses with a few employees: from around £50-£150 per year
• Retail and hospitality: from around £100-£300 per year
• Construction and manual trades: from around £200-£1,000+ per year

These are indicative figures — your actual premium will depend on your specific circumstances. High-risk industries and businesses with a history of claims will pay more.

Many insurers offer EL insurance as part of a business insurance package that also includes public liability and other covers. Bundling can often save money compared to buying each policy separately.

Like all business insurance, employers' liability premiums are an allowable business expense. If you're using Accounted to manage your books, Penny will categorise the expense correctly so it's deducted from your profits on your tax return. It's a cost of doing business, and HMRC recognises that.

When Your Business Grows — Things to Watch For

Your EL insurance needs can change as your business evolves. Keep these triggers in mind:

Hiring your first employee. This is the big one. The moment you take someone on, you need cover. Don't wait until their start date — have the policy in place before they begin work.

Changing the type of work your employees do. If your employees start doing more physical or higher-risk work, your insurer needs to know. Failing to disclose changes could invalidate your cover.

Taking on more staff. Some policies are based on the number of employees or total payroll. If you grow, make sure your policy still provides adequate cover.

Using subcontractors. If you're not sure whether your subcontractors are genuinely self-employed, it's worth getting EL cover that includes them, just in case.

Expanding to new locations. If you open a new premises or start working in different environments, tell your insurer.

The Relationship Between EL and Other Insurance

Employers' liability insurance sits alongside other business insurance policies, each covering different risks:

• Public liability insurance covers claims from members of the public and clients
• Professional indemnity insurance covers claims arising from your professional advice or services
• Business interruption insurance covers lost income if something forces your business to stop operating
• Employers' liability insurance covers claims from employees

These aren't alternatives — they cover different things. As your business grows and you take on more responsibilities, you'll likely need several of these.

Getting Set Up

If you're about to hire your first employee and need to sort out employers' liability insurance, here's a quick action plan:

1. Get quotes. Compare at least three providers. Use an insurance broker if you want someone to do the legwork for you.
2. Check the cover level. Make sure the policy provides at least £5 million of cover (most offer £10 million as standard).
3. Read the policy document. Pay attention to exclusions and notification requirements.
4. Have the policy in place before your employee starts. Not on their first day — before it.
5. Display your certificate. Either physically in your workplace or electronically where employees can see it.
6. Review annually. When your renewal comes round, check that the policy still reflects your business. Update your insurer about any changes in staff numbers, types of work, or locations.
7. Keep records. Retain copies of all your EL insurance certificates, even after policies expire. Claims for workplace injuries can be made years after the event, and you may need to prove you were insured at the time.
