If you run a UK limited company, you’re probably wondering which insurance you’re legally required to have and which is just sensible protection. The short answer: employers’ liability insurance is the only cover that’s compulsory by law, and only once you employ someone other than yourself. Everything else, public liability, professional indemnity, directors’ and officers’ cover, cyber insurance, depends entirely on what your company does, who it deals with, and sometimes what your contracts or professional body demand.
This guide breaks limited company insurance down by what’s mandatory, what’s trade-specific, and what most businesses end up needing anyway, so you can work out your own position without wading through a broker’s sales pitch.
Is business insurance for limited companies a legal requirement?
Mostly no. Beyond employers’ liability, there’s no general law forcing a UK limited company to hold public liability, professional indemnity, or any other type of business cover. What changes the picture is your trade, your clients, and your contracts. A landlord might demand proof of public liability before signing a lease. A professional body might make professional indemnity a condition of membership. A client’s procurement team might insist on cyber cover before they’ll sign anything. None of these come from government legislation, but in practice they can matter just as much as the one cover that actually is compulsory.
Employers’ liability insurance: the one that’s actually the law
Employers’ liability (EL) insurance is required under the Employers’ Liability (Compulsory Insurance) Act 1969 the moment your limited company employs anyone who isn’t exempt. It covers compensation and legal costs if a staff member is injured or falls ill because of their work.
The rules in plain terms
- You need a minimum of £5 million of cover, though most insurers default to £10 million as standard.
- The policy must come from an insurer authorised by the Financial Conduct Authority.
- You must display your certificate, physically or digitally, somewhere staff can see it.
- You’re required to keep old certificates for 40 years, since industrial illnesses like asbestos-related conditions can surface decades later.
The fine for going without it
According to the Health and Safety Executive’s own guidance, you can be fined up to £2,500 for every day you’re operating without required cover, and up to £1,000 separately for not displaying or producing your certificate when an inspector asks. These aren’t one-off penalties; they stack daily, and HSE does prosecute.
The single director exemption, and where it stops
Here’s the part that trips a lot of small limited companies up. If you’re the sole director and sole employee of your company, and you own 50% or more of the share capital, you’re generally exempt from compulsory EL insurance. This is the “solo-director exemption” that lets a one-person consultancy or contractor limited company legally trade without EL cover.
That exemption disappears the moment any of the following happens:
- You take on a second director who’s also paid through the company.
- You hire even one part-time member of staff, an apprentice, or casual help.
- A family member joins the company payroll. Unlike sole traders and partnerships, limited companies cannot use the family-member exemption, even for a spouse or civil partner. That carve-out only applies to unincorporated businesses.
If you’re unsure whether someone counts as an employee for these purposes, the test HSE applies is broadly about control: if you direct how, when and where someone works, and provide their equipment, they’re likely to count even without a formal written contract.
Public liability insurance for limited companies
Public liability insurance isn’t a legal requirement for any UK business, limited company or otherwise, but it’s often the single most useful cover a trading company holds. It pays out if a member of the public, a client, or their property is injured or damaged because of your business activities, and it covers your legal defence costs alongside any compensation.
You’ll typically want it if:
- Customers or clients visit your premises.
- You or your staff work on other people’s property, such as tradespeople, cleaners, or installers.
- Your business deals with the public in any physical capacity, even a courier collecting from your home office.
Premiums for a low-risk, single-director business start from roughly £70 to £180 a year for £1 million or £2 million of cover, though prices climb steeply for higher-risk trades like roofing or scaffolding. Prices change often depending on your sector and claims history, so treat any figure here as a rough guide rather than a quote.
Professional indemnity insurance: do I need it for my limited company?
Professional indemnity (PI) insurance isn’t a legal requirement, but it becomes close to essential the moment your company gives advice, designs something, or delivers a service that a client could later claim cost them money. It covers compensation and legal costs if a client alleges your advice, work, or service was negligent, even if the claim turns out to be unfounded.
You should seriously consider it if you’re a:
- Consultant, accountant, marketing agency, or anyone offering professional advice.
- Architect, engineer, IT contractor, or software developer.
- Financial adviser, solicitor, or anyone regulated by a professional body.
For several regulated professions, PI isn’t optional in practice: bodies including the Solicitors Regulation Authority and various accountancy institutes make it a condition of membership. Even outside regulated fields, many clients now write minimum PI cover into their contracts before they’ll engage you at all. Premiums vary hugely by sector and risk, but low-risk consultancy cover can start from around £321 a year for a £1 million limit, according to broker pricing.
Directors and officers insurance UK: who actually needs it?
Directors’ and officers’ (D&O) insurance covers the personal legal costs and compensation a director or senior officer might face if they’re sued individually for how they managed the company. This matters because a limited company’s liability shield protects the company’s finances, not necessarily a director’s personal ones. If a director is accused of a wrongful act, a breach of duty under the Companies Act 2006, or negligent decision-making, they can be pursued personally, and their own savings and assets are potentially exposed.
D&O cover tends to matter most for:
- Companies with external investors or a board answerable to shareholders.
- Businesses that employ people, since employment tribunal claims can name directors personally.
- Companies bidding for public sector contracts or seeking external funding, where D&O cover is often a due diligence requirement.
- Any director worried about a wrongful trading or breach of duty allegation, particularly if the company is under financial strain.
A single-director micro-business with no outside investors and no staff carries far less D&O risk than a company with a board, employees, and external funding, but the exposure never drops to zero; a disgruntled client, supplier, or former employee can still bring a personal claim.
Cyber insurance for limited companies
Cyber insurance is not a legal requirement for most UK businesses, but it’s become close to standard for any company handling customer data, taking online payments, or relying on cloud software, which by 2026 is most of them. A policy typically covers incident response and forensics, data restoration, business interruption following an attack, and the legal and regulatory costs that follow a breach, including obligations under UK GDPR.
Costs vary widely by turnover and sector. Small businesses commonly pay somewhere between £350 and £5,000 a year, though the figure climbs for firms handling large volumes of card payments or sensitive data. Basic security measures, such as multi-factor authentication and Cyber Essentials certification, can noticeably reduce your premium and are increasingly expected by insurers before they’ll quote at all.
Structuring cover by business type
Here’s a quick way to place yourself:
- Solo director, no staff, no premises, advisory work (freelance consultant, developer): EL exempt if you meet the 50%+ shareholding rule; PI usually essential; D&O and cyber worth considering if you handle client data.
- Small trading business with staff, physical premises: EL compulsory; public liability strongly recommended; contents or buildings cover depending on ownership.
- Client-facing tradesperson (electrician, builder, plumber): EL compulsory once you have staff; public liability close to essential; consider tools and equipment cover.
- Regulated professional practice (accountancy, financial advice, legal services): PI often mandatory through your professional body; EL compulsory with staff; D&O worth reviewing as the practice grows.
- Company with investors, a board, or public sector contracts: D&O becomes a priority regardless of size; EL and public liability as above depending on staff and premises.
FAQs
Do I need insurance for my limited company?
Only employers’ liability insurance is a legal requirement, and only once you employ someone other than yourself under the 50%+ shareholding solo-director exemption. Everything else, including public liability and professional indemnity, depends on your trade, your contracts, and what your clients or professional body require.
What happens if I don’t have employers’ liability insurance when I should?
The Health and Safety Executive can fine you up to £2,500 for every day you’re operating without required cover, plus a separate fine of up to £1,000 for failing to display or produce your certificate. You’d also have to cover any employee compensation claim from company funds, with no insurance to fall back on.
Is a single director of a limited company exempt from employers’ liability insurance?
Yes, if you’re the sole director, the only person on the payroll, and you own 50% or more of the company’s share capital. That exemption ends as soon as you employ anyone else, including a second director drawing a salary or a family member on the payroll.
Does a limited company need public liability insurance by law?
No, public liability insurance isn’t a legal requirement for any UK business. It’s widely held because it covers claims from members of the public or clients injured or affected by your business activities, and many landlords and clients require proof of it before they’ll work with you.
What’s the difference between public liability and professional indemnity insurance?
Public liability covers physical injury or property damage caused by your business, while professional indemnity covers financial loss a client suffers because of your advice, design, or service. A tradesperson typically needs public liability; a consultant or adviser typically needs professional indemnity, and some businesses need both.
Do I need directors and officers insurance for a small limited company?
Not always, but risk grows with employees, external investors, and public sector contracts. A single-director company with no staff carries lower exposure, but directors can still be personally sued over decisions like wrongful trading or breach of duty, so it’s worth reviewing rather than dismissing outright.
Is cyber insurance compulsory for UK limited companies?
No, cyber insurance isn’t a legal requirement for most UK businesses, but GDPR obligations and the financial fallout of a breach apply regardless of whether you’re insured. Many companies now find clients or contracts effectively require it even though the law doesn’t.
Can I get all these covers in one policy?
Yes, most insurers offer combined business insurance policies that let you bundle employers’ liability, public liability, professional indemnity and other covers into one package, often cheaper than buying separately. You typically only pay for the specific covers your business needs, so it’s worth comparing quotes rather than assuming a package price is fixed.
