Self-employment & Sole Trader
UK-wide

A plain-English guide to business insurance for UK freelancers, contractors and sole traders in 2026/27. The headline: almost none of it is legally required. The single exception is Employers Liability insurance, compulsory the moment you employ staff. The covers that matter most in practice - Professional Indemnity and Public Liability - are driven by your client and agency contracts, not by statute. This guide explains what each cover does, what recruitment agencies typically demand, the other products worth considering, and how premiums are treated for tax.

This is general information, not regulated financial or insurance advice. Cover levels and policy wordings vary between insurers - read the schedule of any contract that requires insurance and buy cover that matches it.

Do you legally need business insurance?

For most self-employed people, the honest answer is no. There is no general law forcing a freelancer, contractor or sole trader to hold Professional Indemnity, Public Liability, or any of the optional business covers. The obligations that do exist come from two places:

The law requires only one thing: Employers Liability insurance, and only if you employ staff. Everything else is your choice.
Your contracts may require cover as a condition of the work. Recruitment agencies and end clients routinely make Professional Indemnity and Public Liability a contractual pre-condition. That is not a legal duty on you as a business, but you cannot take the assignment without it - so treat it as non-negotiable for that job.

So the practical question is not "am I forced by law to insure?" but "what would go wrong for me, and what do my clients demand?" The rest of this guide works through each cover on that basis.

Employers Liability - the one legal requirement

Minimum cover

£5m

ELCI Regulations 1998, reg 3

Fine if uninsured

£2,500/day

For each day without cover

Certificate fine

£1,000

Not displaying / providing it

If you employ staff, Employers Liability (EL) insurance is compulsory under the Employers Liability (Compulsory Insurance) Act 1969. It covers your legal liability if an employee is injured or made ill through their work and claims against you. You must be insured for at least £5 million with an approved insurer (the £5m minimum is set by regulation 3 of the Employers Liability (Compulsory Insurance) Regulations 1998; in practice most insurers offer £10 million as standard). You must also make the certificate of insurance available to employees.

Penalties are steep: HSE inspectors can fine you up to £2,500 for every day you are not properly insured, and up to £1,000 if you do not display the certificate or make it available on request.

When you do not need Employers Liability

You are exempt if you fall into one of these cases (per GOV.UK and HSE guidance):

You have no employees at all - a genuine sole trader working alone does not need EL.
You only employ close family members (spouse, civil partner, parent, child, sibling, and the other relatives listed by GOV.UK). Important exception: this family exemption does not apply if the business is an incorporated limited company.
Your only employee is based outside England, Scotland and Wales.
Single-director companies: a company that employs only its owner, where that person also owns 50% or more of the issued share capital, is exempt. This is why a typical one-person contractor limited company with a sole director-shareholder and no other staff does not legally need EL.

The exemptions ultimately derive from section 3 of the 1969 Act and Schedule 2 to the 1998 Regulations. If you take on any other employee - even part-time or temporary - the £5m EL requirement applies from day one.

Professional Indemnity - when clients and agencies require it

Professional Indemnity (PI) insurance covers compensation you may have to pay a client for losses caused by the services or advice you provided - a design error, a coding mistake, a missed deadline, or negligent professional advice. It is not a legal requirement for most trades, but it becomes effectively mandatory in two situations:

Contract-driven. Recruitment agencies and end clients very commonly require PI as a condition of the assignment - standard for IT, engineering, consultancy, marketing and creative contractors. The contract sets the minimum, often stated as £1 million or £2 million of cover.
Regulator-driven. Some regulated professions must hold minimum PI cover set by their regulator - for example solicitors, accountants, architects and financial advisers. For those professions PI genuinely is mandatory, but through professional regulation rather than a general insurance law.

If you give advice or deliver professional work to clients, PI is the cover most worth having even when nobody insists on it - a single negligence claim can dwarf a year's fees.

Public Liability - third-party injury and damage

Public Liability (PL) insurance covers claims from members of the public for injury or property damage connected with your business activities - a client tripping over your cables, or accidental damage you cause while working at a customer's premises. It is not required by law, but your need for it is driven by how you work:

If clients or the public visit your premises, PL matters.
If you go to client sites or work in public spaces, PL matters.
A purely remote, desk-based freelancer who never meets clients in person has a much lower PL exposure - though many still carry it because clients ask for it.

As with PI, PL is frequently written into client and agency contracts as a minimum cover level, so check what your assignment requires before deciding you can skip it.

Contractor-specific: what agency contracts typically demand

If you contract through a recruitment agency or via your own limited company on client assignments, the insurance you actually need is usually dictated by the contract, not by statute. A typical agency or end-client schedule will require some combination of:

Cover	Why the contract asks for it	Status
Professional Indemnity	Protects the client if your work or advice causes them a financial loss	Often required by the contract (commonly a stated minimum such as £1m or £2m)
Public Liability	Protects third parties for injury or property damage on site	Often required, especially where you work on client premises
Employers Liability	Required by law if you employ anyone through your business	Legally required (£5m+) only if you have employees

Treat the cover levels above as illustrative of what agencies commonly ask for, not fixed rules - the exact figures are whatever your specific contract states. Always read the insurance clause of the assignment and buy to match. Most single-person contractor companies do not employ anyone, so Employers Liability is usually not needed unless you take on staff.

Other useful cover

None of the following is legally required, but each addresses a real risk that can stop a small business in its tracks:

Business equipment / contents. Covers laptops, cameras, tools and stock against theft, loss or damage - useful if your kit is expensive or essential to earning.
Cyber insurance. Covers the cost of responding to a data breach, ransomware or a cyber attack, including recovery, notification and liability. Relevant if you hold client data or run on connected systems.
Tax investigation (fee protection) insurance. Covers the accountancy fees incurred if HMRC opens an enquiry into your tax return - not the tax itself, but the professional cost of dealing with it.
Personal income protection. Pays you a replacement income if illness or injury stops you working. Important because the self-employed cannot claim Statutory Sick Pay - see the note below.
Critical illness cover. Pays a lump sum on diagnosis of a specified serious condition.

Because sole traders get no Statutory Sick Pay, personal income protection is one of the most commonly under-bought covers among the self-employed. Choose based on your actual exposure: what would genuinely wipe out your income or savings if it went wrong.

Cost and tax - premiums as an allowable expense

Premiums are priced on risk, so there is no universal figure. Insurers set the cost from factors such as your profession and risk profile, your turnover or fee income, the cover level required, your claims history and where you work. Higher required cover, higher-risk work, and professional-advice roles all push premiums up. Because the drivers vary so widely, this guide deliberately does not quote a "typical" premium - get quotes for your specific activity and the cover levels your contracts demand.

Tax treatment

Premiums for insurance taken out wholly and exclusively for your business are generally an allowable business expense - you deduct them from your income when working out your taxable profit. GOV.UK lists insurance among the allowable financial costs for the self-employed. That covers business policies such as Professional Indemnity, Public Liability, Employers Liability and business equipment cover.

Personal policies are treated differently: personal income protection and life cover premiums are usually not deductible against your business profits. If you are unsure whether a particular policy qualifies, check with HMRC or your accountant before claiming it on your Self Assessment return.

Frequently asked questions

Do I legally need business insurance if I am self-employed?

For most self-employed people and contractors, business insurance is not a legal requirement. The one exception is Employers Liability (EL) insurance: if you employ staff you must hold at least £5 million of EL cover under the Employers Liability (Compulsory Insurance) Act 1969, and you can be fined up to £2,500 for every day you are uninsured. Sole traders and single-director companies with no employees usually do not need EL. Professional Indemnity and Public Liability are not required by law, but clients and recruitment agencies very often require them in the contract, so in practice most contractors carry them.

What insurance does a contractor need?

There is no single legal answer - it depends on your contract. Recruitment agencies and end clients commonly require contractors to hold Professional Indemnity (to cover claims for mistakes or negligent advice), Public Liability (to cover injury or damage to third parties or their property), and Employers Liability if the contractor employs anyone. The specific cover levels are set by the contract, not by statute, and are often stated as a minimum such as £1 million or £2 million of Professional Indemnity and a higher figure for Public Liability. Always read the schedule of your assignment contract and buy to match it. Employers Liability of at least £5 million is legally required only if you actually employ staff.

Is professional indemnity insurance a legal requirement?

For most trades, no - Professional Indemnity (PI) is not required by law. It covers compensation you might have to pay a client for losses caused by services or advice you provided, for example a design error, a missed deadline, or negligent professional advice. PI becomes effectively mandatory in two situations: where your client or recruitment agency requires it in the contract, which is very common for IT, engineering, consultancy and creative contractors; and where you work in a regulated profession whose regulator mandates minimum PI cover, such as solicitors, accountants, architects or financial advisers. Outside those cases PI is optional but widely recommended for anyone giving advice or delivering professional services.

Do sole traders need public liability insurance?

Public Liability (PL) insurance is not a legal requirement for sole traders. It covers claims from members of the public for injury or property damage connected with your business - for example a client tripping over your equipment, or damage you cause while working on someone else's premises. Whether you need it depends on your risk: if clients visit you, if you visit their premises, or if you work in public spaces, PL is strongly advisable and is often demanded in client and agency contracts. A purely desk-based sole trader who never has clients on site and never works on third-party premises has a much lower need for PL, though many still carry it because clients ask for it.

When is employers liability insurance compulsory?

Employers Liability (EL) insurance is compulsory as soon as you employ anyone, under the Employers Liability (Compulsory Insurance) Act 1969 and the 1998 Regulations. You must be insured for at least £5 million with an approved insurer, and you must make the certificate available to your employees. You can be fined up to £2,500 for each day you are not properly insured, and up to £1,000 for failing to display or provide the certificate. You do not need EL if you only employ close family members (unless the business is an incorporated limited company), if the only employee is based outside England, Scotland and Wales, or if the company employs only its owner who also holds 50% or more of the issued share capital. Most single-director limited companies with no other staff fall in that last exemption.

Does a single-director limited company need employers liability insurance?

Usually no. HSE guidance confirms that a company employing only its owner, where that person also owns 50% or more of the issued share capital, is exempt from compulsory Employers Liability insurance. So a typical one-person contractor limited company with a sole director-shareholder and no other employees does not legally need EL. The moment you take on any other employee - even part-time - you must hold at least £5 million of EL cover. Note the family-business exemption does not apply to incorporated limited companies, so employing a relative through your Ltd would still require EL.

What other business insurance might a freelancer want?

Beyond the three liability covers, common optional products include: business equipment or contents insurance for laptops, cameras and tools; cyber insurance covering data breaches, ransomware and the cost of responding to an incident; tax investigation (fee protection) insurance covering the accountancy fees of an HMRC enquiry; and personal income protection or critical illness cover, which pay you an income or lump sum if illness stops you working - important because the self-employed cannot claim Statutory Sick Pay. None of these are legally required. Choose based on your actual exposure: what would genuinely stop your business or wipe out your savings if it went wrong.

Can I claim business insurance as an allowable expense?

Yes. Premiums for insurance taken out wholly and exclusively for your business are generally an allowable business expense that you deduct from your income when working out your taxable profit. GOV.UK lists insurance among the allowable financial costs for the self-employed. That covers Professional Indemnity, Public Liability, Employers Liability, business equipment cover and similar business policies. Personal policies are treated differently: personal income protection and life cover premiums are usually not deductible against your business profits. If you are unsure whether a specific policy qualifies, check with HMRC or your accountant before claiming.
