Understanding Employer's Liability Insurance Requirements
If you employ anyone in the UK, you are almost certainly required by law to have employer's liability insurance. Yes, legally mandatory—not optional, not "just a good idea." Understanding employer's liability insurance requirements is one of those non-negotiable obligations, right up there with payroll tax and not claiming your cat as a business expense. Get it wrong, and the fines start at £2,500 per day. Not per incident. Per day. While your business sits uninsured, the meter runs. This guide walks you through what you actually need, who counts as an employee, and why skipping this is a genuinely false economy.
What is employer's liability insurance?
Employer's liability (EL) insurance covers you against claims from employees who are injured or become ill as a result of their work for you. If an employee sues you for compensation, your EL insurance pays the legal costs and any damages awarded.
Workplace injuries and illnesses are far more common than many small-business owners assume. They don't just happen on construction sites or factory floors. An office worker can develop repetitive strain injury from a poorly set-up desk. A warehouse operative can slip on a wet floor. A remote worker can develop stress-related illness linked to working conditions. Even a delivery driver whose van breaks down during their shift could claim that poor maintenance was your responsibility.
Without EL insurance, you would pay these costs out of your own pocket. Compensation awards for serious injuries? They run into hundreds of thousands of pounds. That's the gap between a manageable insurance claim and a financial catastrophe.
The legal requirement
Under the Employers' Liability (Compulsory Insurance) Act 1969, enforced by the Health and Safety Executive (HSE), most employers must carry EL insurance with a minimum cover of £5 million. In practice, nearly all policies offer £10 million as standard.
You must have EL insurance from the moment you take on your first employee—this includes part-time workers, temporary staff, apprentices, and even some volunteers. The policy must come from an authorised insurer. You cannot self-insure unless you fall into a very specific exemption.
Who is exempt?
Only a small number of employers escape the requirement entirely:
- Sole traders with no employees (you cannot insure yourself as your own employee)
- Family businesses where all employees are closely related to the owner (spouse, child, parent, sibling)—but only if the business is not a limited company
- Some public bodies, including government departments and NHS trusts
- Companies where the sole employee owns 50% or more of the shares—incorporated businesses only
If you employ even one person outside these categories, you need EL insurance. There is no exemption based on business size, industry, or perceived risk level.
Who counts as an employee (and when a contractor isn't)
This is where things get complicated. For EL purposes, "employee" includes:
- Full-time and part-time employees
- Temporary and fixed-term workers
- Apprentices and trainees
- Labour-only subcontractors working under your direction
- Volunteers, if they receive any form of payment or benefit
The critical test is control. If you tell them what to do, when to do it, and how to do it, they are likely treated as employees for EL purposes, regardless of what their contract says. A genuine self-employed contractor who controls their own methods and supplies their own equipment generally isn't covered—but the boundary is genuinely blurred. For the finer points, see our guide to understanding IR35 and off-payroll working rules.
When you hire new employees, notify your insurer, especially if the new hire changes the nature of your work or significantly increases your headcount. The same applies if you hire apprentices—your insurer needs to know.
What's covered (and what absolutely isn't)
EL insurance typically covers:
- Compensation awarded to an employee for workplace injury or illness
- Legal defence costs, including solicitor fees, court costs, and expert witness fees
- Out-of-court settlements agreed between you and the claimant
- The claimant's legal costs if they win
It does not cover:
- Fines or penalties imposed by regulators (like the HSE)
- Deliberate acts by the employer
- Contractual liabilities outside the scope of the policy
- Injuries to non-employees (that's public liability insurance—a completely separate policy)
The policy responds to claims made during the policy period, regardless of when the injury occurred. This matters for diseases with long latency periods—asbestosis, occupational deafness, mesothelioma—where a claim might arrive decades after exposure. Your insurer still has to respond.
Cost, compliance, and penalties
How much does it cost?
Premiums vary widely depending on industry, headcount, claims history, and the nature of work. A small office-based business with five employees might pay £100 to £300 per year. A construction company with the same headcount could pay several thousand.
Factors that affect your premium:
- Industry risk profile. Construction, manufacturing, and agriculture attract higher premiums than office-based sectors.
- Number of employees. More staff means more exposure.
- Claims history. Previous claims increase your premium.
- Turnover and payroll size. Used as proxies for business size.
- Health and safety record. Demonstrating good practices can reduce your premium.
Shopping around and using a specialist broker helps you find competitive rates without sacrificing cover.
Displaying your certificate
You must display your EL insurance certificate where employees can easily access it. This can be a physical copy in the workplace or an electronic copy via your company intranet or HR system. If you have multiple workplaces, each one should have access. Digital display is now widely accepted—just make sure it is genuinely accessible, not buried in a folder nobody knows about.
You must also keep copies of old certificates for at least 40 years, because occupational disease claims can arrive long after exposure. Store them securely in both physical and digital formats.
Penalties for non-compliance
The penalties are significant:
- Up to £2,500 per day that you are without cover. This accrues daily.
- Up to £1,000 for not displaying or making the certificate accessible to employees
- Personal liability for compensation claims that arise during any uninsured period
The HSE enforces these requirements and inspects EL documentation during routine visits or investigations.
Managing the risk: prevention beats insurance
Having EL insurance is a legal backstop, not a substitute for good health and safety practices. The best way to manage risk is to prevent injuries from happening in the first place.
This means:
- Conducting regular risk assessments using the HSE's simple health and safety guide
- Providing appropriate training and protective equipment
- Maintaining a safe working environment
- Recording and investigating incidents promptly
- Encouraging employees to report hazards without fear of reprisal
Good practices also reduce your insurance premiums over time—a genuine virtuous cycle.
Keeping EL insurance current, displaying the certificate, and maintaining 40-year records requires organisation. When you manage national insurance contributions and statutory leave entitlements, integrate insurance management into that same annual compliance process. Changes to business activities, premises, or working arrangements should be reported to your insurer to ensure your cover remains valid.
Frequently Asked Questions
Q: Do I need EL insurance if I only employ family members?
A: If your business is not a limited company and all employees are closely related to you (spouse, child, parent, sibling), you may be exempt. But this exemption is narrow. If you are a limited company or employ anyone outside this close family circle, you must have cover.
Q: What's the difference between EL and public liability insurance?
A: EL covers claims by your employees. Public liability covers claims by members of the public, customers, or visitors. They are separate policies. Do not assume your public liability cover includes employee claims—it almost certainly doesn't.
Q: If I use subcontractors, do I need to include them on my EL insurance?
A: It depends on control. If they are labour-only subcontractors working under your direction, they should be treated as employees for EL purposes and your insurer should know about them. Genuine self-employed contractors who control their own methods are generally not covered. When in doubt, tell your insurer.
Q: Can I self-insure instead of buying a policy?
A: No, unless you fall into a very specific regulatory exemption. Almost all small businesses must buy an EL policy from an authorised insurer.
Q: What happens if I don't display the certificate?
A: You can be fined up to £1,000, even if you have valid cover. Display it prominently or make it easily accessible via your HR system.
Q: How long do I need to keep old certificates?
A: At least 40 years. Occupational disease claims can arise decades after exposure, and you may need to prove you had cover at the time. Store them securely in both physical and digital formats.
Q: Does EL insurance cover injuries caused by my own negligence?
A: Yes, in most cases. EL insurance is designed to cover exactly these situations—that is the whole point. The main exceptions are deliberate acts by the employer or breaches of policy conditions.
Q: When should I notify my insurer about changes to my business?
A: As soon as they happen. Changes to headcount, working arrangements, premises, or the nature of work can affect your cover. Waiting until a claim arrives is far too late.
Employer's liability insurance is one of those business essentials that you hope you will never need to use. But when an employee is injured and the claim lands on your desk, having the right cover in place is the difference between a manageable process and a financial catastrophe. If you are unsure whether you have valid cover, contact your insurer or broker now. Do not wait.
