UK Business Insurance — What You Actually Need

Business insurance in the UK ranges from legally compulsory cover to policies that are commercially essential even when not required by law. This guide cuts through jargon to explain exactly which policies you need, what they cover, and what they cost.

1. Insurance You Must Have by Law

Two types of insurance are compulsory in Great Britain:

• Employers' Liability (EL) insurance — required under the Employers' Liability (Compulsory Insurance) Act 1969 for any business that employs one or more people. The minimum cover is £5 million per occurrence (most policies provide £10 million as standard). The EL certificate must be displayed at each workplace where employees can see it, or made available electronically. Failure to hold a valid policy carries an HSE fine of up to £2,500 per day. Limited exemptions apply to certain family businesses.
• Motor insurance — if any vehicle is used for business purposes (including your own car used to visit clients), you must have at least third-party motor insurance that covers business use. Standard personal motor policies typically exclude business use — check your policy schedule and add business use endorsement if needed. Commercial vehicle policies cover vans, lorries, and fleet vehicles.

2. Public Liability

Public Liability (PL) insurance is not required by statute but is commercially essential for virtually any business that interacts with members of the public, clients, or third parties. It covers:

• Bodily injury to a third party (e.g. a client trips over your equipment)
• Damage to third-party property (e.g. you accidentally damage a client's premises)
• Legal defence costs and compensation awards

Standard cover levels are £1M, £2M, £5M, and £10M. Most public venues, commercial landlords, and larger clients require a minimum of £1M–£2M as a condition of entry or contract. Typical annual costs for a sole trader or small business range from £100 to £500 for £1M cover, depending on trade and turnover.

PL does not cover damage to your own property or injury to your own employees — that is covered by Employers' Liability and commercial property insurance respectively.

3. Professional Indemnity

Professional Indemnity (PI) insurance protects businesses that provide advice, consultancy, design, or professional services against claims of negligence, errors, or omissions. If a client suffers a financial loss they attribute to your advice or work, PI covers your legal defence costs and any damages awarded.

PI is particularly important for:

• Accountants, solicitors, architects, engineers, and surveyors (often required by their professional bodies)
• FCA-regulated financial advisers and mortgage brokers (required by the FCA)
• IT consultants, web developers, and software companies
• Management consultants, PR agencies, and marketing firms

Cover levels range from £100k to £2M+. PI is written on a claims-made basis — the policy active when the claim is made (not when the work was done) responds. Maintain retroactive cover when switching insurers to avoid gaps for historic work.

4. Product Liability

Product Liability insurance covers claims arising from injury or property damage caused by a product you manufacture, supply, or sell. It is relevant to manufacturers, importers, wholesalers, and retailers. Product liability claims are governed by the Consumer Protection Act 1987, which imposes strict liability (the claimant does not need to prove negligence — just that the product was defective and caused damage).

Product Liability cover is often bundled with Public Liability in a combined liability policy — worth checking your policy wording if you sell physical goods. Cover requirements depend on the risk profile of the product: food businesses, children's products, and machinery carry higher inherent risk and therefore need higher limits.

5. Business Interruption

Business Interruption (BI) insurance covers loss of gross profit when your business is forced to close or significantly reduce operations due to a covered insured event — such as fire, flood, or other physical damage to your premises. The key concepts to understand:

• Sum insured — should equal your annual gross profit (turnover minus variable direct costs). Underinsuring the sum insured means proportional claims settlement (average clause)
• Indemnity period — the maximum duration the policy will pay out. A minimum of 24 months is recommended, as full reinstatement of premises and rebuilding customer relationships often takes longer than a year
• Extensions — denial of access (e.g. road closure), loss of utilities, prevention of access due to a notifiable disease (though COVID-19 litigation exposed major coverage disputes here — the FCA test case clarified many but not all policies)

BI only pays when there is a triggering physical damage claim under the associated property policy — it does not pay as a standalone policy without a physical damage trigger, unless you have a specific extension.

6. Cyber Insurance

Cyber insurance is one of the fastest-growing lines of business insurance, reflecting the growing frequency and cost of cyber attacks on SMEs. A cyber policy typically covers:

• Forensic investigation costs to identify the breach
• Legal costs and regulatory notification obligations under UK GDPR
• Costs of notifying affected individuals and providing credit monitoring
• Crisis communications and PR to manage reputational damage
• Business interruption losses during system recovery (this is additive to any standard BI policy)
• Ransomware payments (subject to policy conditions and OFAC/sanctions screening)
• Third-party liability claims from individuals whose data was compromised

Importantly, ICO regulatory fines (up to £17.5M or 4% of global turnover) are not insurable in the UK — it is against public policy to insure against punitive regulatory penalties. Cyber policies also typically exclude nation-state attacks (war exclusion) and pre-existing vulnerabilities that were known and unpatched.

7. Directors & Officers (D&O)

Directors & Officers (D&O) insuranceprotects the personal assets of company directors and officers against claims alleging wrongful acts in their management of the company. Unlike most insurance (which protects the company), D&O protects individuals. Claims can arise from:

• Creditors alleging wrongful trading or fraudulent preference
• Regulatory investigations by Companies House, HMRC, the FCA, or the CMA
• Shareholder derivative actions
• Employment tribunal claims brought against the director personally
• Data protection actions under UK GDPR

D&O is particularly important for limited companies, as directors have personal duties under the Companies Act 2006 (sections 171–177) and can face personal liability for breach. The policy typically has three parts: Side A (individual cover where the company cannot indemnify), Side B (reimburses the company where it has indemnified the director), and Side C (entity cover for securities claims).

8. Key Person Insurance

Key person insurance (also called key man insurance) is a life insurance or critical illness policy taken out by a business on a key employee or director whose absence would materially harm the business. The business is both the policyholder and the beneficiary.

It is designed to cover:

• Lost revenue during the period of replacing or retraining staff
• Recruitment and onboarding costs for a successor
• Loan repayment (some lenders require key person cover as a condition of a business loan)

HMRC's treatment of key person insurance premiums is nuanced. Where the policy is purely for trading purposes (replacing lost profit) HMRC may allow the premiums as a trading expense, but will then tax the proceeds. Where the policy is for capital purposes (e.g. repaying a loan) premiums are generally not deductible. Always seek specific tax advice before structuring a key person policy.

9. Trade Credit Insurance

Trade credit insurance (also called debtor insurance or accounts receivable insurance) protects businesses against the risk that customers fail to pay invoices — due to insolvency, protracted default, or political risk in export markets. It is particularly relevant for B2B businesses with significant debtor books and high concentration risk (one large customer representing more than 25% of turnover).

For exporters, the UK Export Finance (UKEF)is the government's export credit agency and provides guarantees and insurance for businesses unable to obtain adequate cover in the commercial market. UKEF products include the Export Insurance Policy (EXIP) and bond support guarantees.

Trade credit insurance premiums typically range from 0.1% to 0.5% of insured turnover, depending on the credit risk profile of the debtor book. Insurers (Atradius, Euler Hermes, Coface) conduct continuous monitoring of your customers' financial health and may reduce or withdraw limits if credit risk deteriorates.

10. How to Buy

There are two main routes to purchasing business insurance:

• Insurance broker — an FCA-authorised broker searches the market on your behalf and provides personalised advice. A good broker will analyse your specific risks, recommend appropriate cover levels, and assist with claims. Brokers are remunerated by commission from insurers or by fee. Recommended for complex risks, larger businesses, and any business in a regulated sector.
• Comparison and direct platforms — Simply Business and Superscript offer online comparison tools for common SME policies. Hiscox, AXA, and Zurich also sell direct. These platforms are cost-effective for straightforward risks but provide less tailored advice and claims support.

Read the policy wording, not just the summary. Key areas to check: the definition of covered events, exclusions (particularly pre-existing conditions, known circumstances, and acts of God), the basis of claims settlement (indemnity vs new-for-old), excess and deductible amounts, and any notification conditions (many policies require you to notify within strict timeframes of becoming aware of a circumstance that may give rise to a claim).
