Employers' Liability Insurance in the UK: The Legal Duty Explained

Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-06

Most business insurance is a judgement call. You weigh the risk, look at what your contracts demand, and decide what cover makes commercial sense. Employers' liability insurance is different. It is the one cover where Parliament has taken the decision out of your hands: if you employ people, the law says you insure them. That has been the position since the Employers' Liability (Compulsory Insurance) Act 1969, and it applies whether you run a scaffolding firm with thirty operatives or a café with one Saturday member of staff.

This page explains what the cover actually does, when the legal duty bites, what the £5 million statutory minimum means in practice, who is exempt, and what your obligations are around the certificate. It is written for UK business owners making a real buying decision — not as a legal textbook.

What does employers' liability insurance actually cover?

Employers' liability insurance protects your business against its legal liability to compensate employees who are injured or become ill because of their work. If an employee sues you — or, as is often the case, a solicitor pursues a claim on their behalf — the policy responds to the compensation awarded and, crucially, the legal costs of defending the claim. Defence costs alone can be substantial even where a claim ultimately fails, which is one reason the cover matters to well-run businesses as much as careless ones.

The claims themselves fall into two broad families. The first is accident claims: the warehouse operative injured lifting stock, the chef burned in a kitchen, the labourer struck by falling materials, the office worker who trips over trailing cables. These tend to surface quickly and resolve within a few years.

The second family is slower and, for many employers, more dangerous: disease and long-tail claims. Industrial deafness from years of unprotected noise exposure, hand-arm vibration syndrome in tradespeople who used power tools daily, occupational asthma and dermatitis from dust, sprays and chemicals, and respiratory disease from historic exposures. These claims can arrive decades after the work was done, and they attach to the insurer who was on cover when the exposure happened — not the insurer you happen to have today. That is why your insurance history matters as much as your current policy, and why we tell clients to keep a permanent record of every employers' liability policy they have ever held.

Is employers' liability insurance a legal requirement?

Yes — for the vast majority of UK employers. The Employers' Liability (Compulsory Insurance) Act 1969 requires employers carrying on business in Great Britain to insure against liability for bodily injury or disease sustained by their employees arising out of and in the course of their employment. The policy must be held with an authorised insurer — you cannot self-insure your way around the Act unless you fall into one of the narrow exempt categories discussed below.

It is worth being precise here, because this is where a lot of online guidance blurs together and gets it wrong. Employers' liability is the cover that is required by statute when you have staff. Public liability insurance — which covers injury to members of the public and damage to third-party property — is not a legal requirement for most businesses; it is bought because contracts, sites, landlords and common sense demand it. Motor insurance is a separate legal requirement under the Road Traffic Act 1988 for vehicles used on the road. Three different covers, three different reasons to hold them. Only one of them is compulsory simply because you employ people.

Enforcement sits with the Health and Safety Executive. Inspectors can ask to see evidence of your insurance, and an employer who fails to hold valid cover, or fails to make the certificate available when required, can face financial penalties. We deliberately do not quote specific fine figures here — the honest position is that the penalty regime is a poor reason to buy the cover anyway. The real exposure is an uninsured injury claim, which for a serious accident can run to sums that would end most small businesses outright.

Who counts as an "employee" for this purpose?

Wider than most owners assume. The duty is not limited to permanent staff on your payroll. When we assess whether a client needs employers' liability cover — and how much of their wage roll to declare — we look at everyone who works under their direction, including:

• Full-time and part-time employees, including casual and seasonal staff — a single part-timer is enough to trigger the duty.
• Labour-only subcontractors — people who supply their labour while you supply materials, direction and control. In the eyes of insurers and, frequently, the courts, they are treated as your employees. This catches a huge number of construction and trades businesses who believe "they're all self-employed" puts them outside the Act.
• Apprentices, trainees and people on work experience — often young, often inexperienced, and statistically among the more likely to be injured.
• Temporary and agency workers, depending on the arrangements — who is responsible for insuring them should be checked, not assumed.
• Volunteers, in some circumstances — if you direct their work, tell your insurer so the policy is set up to respond.

Genuine bona fide subcontractors — businesses that work under their own direction, supply their own materials and plant, and carry their own insurance — sit differently, and your liability to them is usually a public liability matter rather than an employers' liability one. But the line between labour-only and bona fide is drawn by the reality of the working relationship, not by what an invoice says. If you use subcontract labour in any form, this is exactly the conversation to have with a broker before a claim tests the answer for you.

How much cover do I need — and what does the £5 million minimum mean?

The statutory minimum limit of indemnity is £5 million. That is the floor set by law: your policy must provide at least £5 million of cover for claims arising from any one occurrence.

In practice, you will rarely see a policy written at exactly £5 million. The standard market position for many years has been to issue employers' liability cover with a £10 million limit as a matter of course, and most package and combined liability policies we arrange include it at that level without a meaningful premium difference. Given that a catastrophic injury claim for a young employee — lifetime care, loss of earnings, and legal costs on both sides — can consume an enormous sum, the higher limit is not a luxury.

Two situations deserve particular attention. First, if you work on larger contracts, principal contractors and public-sector clients sometimes specify employers' liability limits in their contract conditions — check what you have signed up to, because a contractual requirement above your policy limit is a gap you are carrying personally. Second, if your business involves multiple employees travelling together — a gang in one van heading to site, for example — a single accident could generate several serious claims from one occurrence, which is precisely the scenario limits exist for.

Are any employers exempt?

A small number, and the exemptions are narrower than the folklore suggests. Speaking in general terms, the main categories are:

Certain family businesses. Some unincorporated businesses that employ only close family members fall outside the compulsory requirement. Note the word unincorporated — the moment the business is a limited company, the family exemption generally does not help you.

Some single-person limited companies. A company whose only employee also owns a substantial majority of its issued share capital may be exempt. This is the exemption many one-person contractor companies rely on — but it evaporates the day you take on anyone else, even briefly, even part-time. If you are a sole director considering your first hire, the insurance needs to be in place from day one of their employment, not after their first payslip.

Certain public bodies. Various government and public organisations are exempt because the state effectively stands behind their liabilities. This has no relevance to ordinary commercial businesses.

Two practical cautions. Being exempt from the legal duty does not make you immune to a claim — an exempt family business whose employee is seriously injured still faces the liability, just without an insurer behind it, which is why many exempt employers sensibly buy the cover anyway. And if you are relying on an exemption, make sure you actually qualify; the cost of being wrong is an uninsured injury claim plus regulatory exposure. When clients ask us whether an exemption applies to their setup, our usual answer is to check carefully — and then to price the cover regardless, because for most small businesses it is modest money for the removal of an existential risk.

What is the certificate of employers' liability insurance, and what must I do with it?

When your policy is issued, your insurer provides a certificate of employers' liability insurance showing, among other things, the insurer, the policy period and the minimum level of cover. The certificate is not decoration — it comes with duties attached.

You must make the certificate available to your employees. Traditionally that meant displaying a paper copy at each place of business where staff could read it — the laminated sheet on the staff-room noticeboard. The rules also accommodate electronic display, provided your employees know how to access it and can do so reasonably — a copy on the company intranet or a shared drive that everyone genuinely uses will satisfy this for most modern businesses. If you have staff who do not sit at screens — site operatives, kitchen staff, drivers — the noticeboard approach still has a lot to recommend it.

You should also be prepared to show the certificate to a health and safety inspector on request. And although the old requirement to retain expired certificates for decades has been relaxed, we strongly advise every employer to keep permanent records of all past employers' liability policies — insurer names, policy numbers and periods of cover. Disease claims surface twenty, thirty, forty years after exposure, and the employer who can point to the insurer on risk at the time is in a vastly better position than the one hunting through a defunct filing cabinet. The Employers' Liability Tracing Office exists to help trace historic policies, but your own records are the first and best line of defence.

How does employers' liability fit alongside my other covers?

Employers' liability rarely travels alone. For most trading businesses it sits inside a package or combined liability policy alongside public liability, and the two are easily confused, so it is worth restating the division of labour. Employers' liability responds when your employee is injured or made ill by the work. Public liability responds when someone else — a client, a visitor, a passer-by — is injured, or their property is damaged, by your activities. The first is required by statute once you employ; the second is required by contracts and prudence rather than by law. A builder whose labourer falls from a tower and whose scaffolding also damages the neighbour's conservatory would be looking at both sections of the same policy for the two different claims.

Buying them together is usually cheaper and administratively cleaner than separate policies, and it avoids the gap-and-overlap problems that arise when covers are bought piecemeal from different providers at different renewal dates. If your business also uses vehicles, remember that motor cover is its own statutory requirement under the Road Traffic Act 1988 and sits on a separate policy — your employers' liability policy is not a substitute for it, though injuries to employees in work vehicles can raise questions about which policy responds, which is another reason to keep your insurances with a broker who can see the whole picture. You can start a quote online and we will build the package around how you actually trade.

What information will I need to get a quote?

Less than you might fear. For employers' liability, the core rating information is what your business does, how many people you employ, your estimated annual wage roll split by the type of work performed (clerical staff are rated very differently from workers at height, for example), your use of labour-only and bona fide subcontractors, and your claims history. Accuracy matters: wage roll declarations are typically adjustable, and describing manual work as clerical to soften a premium is a false economy that surfaces at exactly the wrong moment — claim time.

It also pays to mention anything unusual up front: work at height or depth, work away at third-party premises, heat work, employees working overseas, night work. None of these necessarily makes cover difficult, but all of them belong in the disclosure.
