What Insurance Does My Business Need in the UK? A Complete Guide

Start with the one cover the law actually requires

Most guidance on business insurance blurs the line between what the law demands and what is simply sensible or commercially expected. The distinction matters, because only one type of business cover is compulsory for the majority of UK firms: employers' liability insurance.

Under the Employers' Liability (Compulsory Insurance) Act 1969, almost every business that employs one or more people must hold an employers' liability (EL) policy. This protects against claims from employees who are injured or made ill as a result of their work. The legal minimum cover is 5 million pounds, although insurers routinely issue policies with a 10 million pound limit at little or no extra cost.

The penalties for going without are not trivial. The Health and Safety Executive can fine an uninsured business up to 2,500 pounds for every day it operates without valid EL cover. There are narrow exemptions: many genuinely single-person limited companies where the only employee also owns at least half the shares, and some family businesses where all staff are close relatives, may not need EL. If you are unsure whether you qualify for an exemption, treat that as a question for a professional rather than an assumption to make alone.

The covers contracts demand, even though the law does not

Once EL is in place, the next tier of insurance is driven by commercial pressure rather than statute. These are the policies clients, landlords, local authorities, and trade associations expect you to carry before they will do business with you.

Public liability insurance

Public liability (PL) insurance covers claims from members of the public, clients, or third parties who suffer injury or property damage connected to your business activities. A customer slipping in your shop, a tradesperson damaging a client's home, or a stall collapsing at a market are all classic PL scenarios. It is not required by law, but it is so commonly demanded by contracts and venues that many firms treat it as effectively mandatory. Cover limits of 1 million, 2 million, or 5 million pounds are typical, with higher limits often specified in local authority or large-corporate contracts.

Professional indemnity insurance

Professional indemnity (PI) insurance protects against claims that your advice, designs, or professional services caused a client financial loss. Consultants, accountants, architects, IT contractors, marketing agencies, and many other advisory businesses are routinely asked for PI cover before a contract is signed. For some regulated professions, a professional body sets a minimum PI requirement as a condition of membership or practice. Even where no regulator is involved, a single professional negligence claim can dwarf a small firm's annual turnover, which is why clients insist on it.

Protecting your assets and your income

The third group of policies protects the physical and financial foundations of the business rather than your liability to others.

Buildings, contents, and equipment

If you own commercial premises, buildings insurance covers the structure against fire, flood, storm, and similar perils. If you lease, your landlord usually insures the building and recharges the cost, but you remain responsible for your own contents, stock, fixtures, and fittings. Contents and stock cover replaces items lost to theft, fire, or damage. Equipment cover, sometimes called business equipment or tools cover, protects machinery, tools, and portable kit, including items used away from your main premises. Underinsuring is a common and expensive mistake: if you declare a sum insured well below the true rebuild or replacement value, an insurer may apply "average" and reduce a valid claim proportionately.

Business interruption insurance

Business interruption (BI) insurance covers lost income and ongoing costs when an insured event, such as a fire or flood, forces you to stop or scale back trading. It is usually sold as an add-on to a property or commercial combined policy and is triggered only by physical damage that is itself insured under the same policy, unless you have bought specific extensions. The Supreme Court's 2021 ruling in the FCA business interruption test case clarified how some pandemic-related extensions should be interpreted, and underlined how much the precise policy wording matters. Read the indemnity period (often 12, 24, or 36 months) carefully, because it caps how long the policy will keep paying.

Modern risks: cyber and management liability

Cyber insurance

Cyber insurance covers losses from data breaches, ransomware, hacking, and other digital incidents. A typical policy combines first-party costs (incident response, data recovery, business interruption from an outage, and breach notification) with third-party liability if customer data is exposed. The National Cyber Security Centre reports that small and medium-sized firms are frequent targets precisely because their defences are often weaker than those of large corporations. Holding cyber cover does not remove your obligations under UK data protection law: you still must report qualifying personal-data breaches to the Information Commissioner's Office, generally within 72 hours of becoming aware of them.

Directors and officers insurance

Directors and officers (D&O) insurance protects individual directors and senior managers against claims arising from decisions they make in their roles, such as alleged breach of duty, mismanagement, or regulatory investigations. Because directors of UK companies can be held personally liable under the Companies Act 2006 and other legislation, D&O cover is increasingly common even among smaller limited companies, particularly those seeking investment or operating in regulated sectors.

How to assess your own risks

No checklist replaces a proper look at your specific operation. Work through your activities and ask, at each step, who could be harmed and what it would cost. A useful sequence is: identify your legal duties first (EL if you employ anyone), then your contractual obligations (read what clients and landlords actually require), then your asset exposures (what would it cost to replace premises, stock, and equipment), then your income exposure (how long could you survive a forced closure), and finally your emerging risks (data, technology, and director liability).

Document your assumptions, especially the sums insured and the indemnity periods, because these are the figures most often set too low. Revisit the assessment whenever you take on staff, sign a major contract, move premises, or change what you sell.

Check the FCA register before you buy

Arranging general insurance in the UK is a regulated activity. Any insurer or broker you deal with should be authorised by the Financial Conduct Authority. Before paying a premium, search the firm's name on the Financial Services Register at register.fca.org.uk and confirm that it is authorised to carry on insurance distribution. Check that the trading name and reference number match the entity you are actually dealing with, and be cautious of unsolicited approaches offering cover that seems far cheaper than the market.

Authorisation matters for more than peace of mind. Dealing with an FCA-authorised firm means you generally have access to the Financial Ombudsman Service and, in some circumstances, the Financial Services Compensation Scheme if a firm fails.

If a claim or sale goes wrong: the FOS route

If you have a dispute with an insurer or broker, you must first complain directly to the firm and give it the chance to respond, normally within eight weeks. If you are unhappy with the outcome, or the firm does not respond in time, you can refer the complaint to the Financial Ombudsman Service free of charge. The Ombudsman can consider complaints from smaller businesses that meet its eligibility criteria, broadly micro-enterprises and many small firms below set turnover and balance-sheet thresholds. Keep written records of policy documents, correspondence, and claim submissions, because clear evidence makes any complaint far easier to resolve.

Frequently Asked Questions

What is the only legally required business insurance?

Employers' liability insurance is the only cover required by law for most UK businesses, under the Employers' Liability (Compulsory Insurance) Act 1969. It applies if you employ staff, with a legal minimum of 5 million pounds of cover. The Health and Safety Executive can fine an uninsured business up to 2,500 pounds for each day it trades without valid cover.

What insurance do sole traders need?

A sole trader with no employees is not legally required to hold any business insurance. In practice, many take out public liability cover because clients and venues expect it, and professional indemnity if they give advice or professional services. The right combination depends entirely on what the business does and what its contracts require.

What is business interruption insurance?

Business interruption insurance covers lost income and continuing costs when an insured event, such as a fire or flood, forces you to stop or reduce trading. It is usually an add-on to a property or commercial combined policy and is normally triggered only by physical damage that is itself insured. The indemnity period sets how long the policy keeps paying, so check it carefully.

What is cyber insurance for businesses?

Cyber insurance covers losses from data breaches, ransomware, hacking, and system outages. It typically combines first-party costs, such as incident response and data recovery, with third-party liability if customer data is exposed. It does not remove your duty under UK data protection law to report qualifying personal-data breaches to the Information Commissioner's Office, generally within 72 hours.

How do I find an FCA-authorised insurer?

Search the firm's name on the Financial Services Register at register.fca.org.uk and confirm it is authorised for insurance distribution. Check that the trading name and reference number match the company you are dealing with. Dealing with an authorised firm generally gives you access to the Financial Ombudsman Service and, in some cases, the Financial Services Compensation Scheme.
