Business Insurance Guide for UK Companies

Last updated: May 2026 · 13 min read

Getting the right business insurance is not just good risk management — some covers are legally compulsory, and many contracts require specific minimum limits. This guide explains the main types of UK business insurance, what each covers, and what every business owner needs to know when buying.

1. Employer's Liability Insurance

Employer's liability (EL) insurance is compulsory for virtually every UK business that employs staff. Under the Employers' Liability (Compulsory Insurance) Act 1969 and the 1998 Regulations, any business employing one or more people in Great Britain must hold a minimum of £5 million of EL cover from an FCA-authorised insurer. In practice, most policies provide £10 million as standard.

EL insurance covers the employer's legal liability to pay compensation and costs if an employee suffers injury or illness as a result of their employment. Claims can arise from workplace accidents, industrial diseases (such as mesothelioma, deafness, or dermatitis), and stress-related conditions.

Compliance requirements:

  • The certificate of insurance must be displayed at each workplace (physically or electronically) where employees can easily see it
  • Certificates must be retained for at least 40 years after the policy ends — latent disease claims (such as asbestos-related conditions) may be brought decades after exposure
  • Failure to hold adequate EL insurance carries a fine of up to £2,500 per day — one of the few fixed-penalty provisions in employment law

Limited exemptions apply to certain family businesses (where all employees are close relatives of a sole trader or partnership) and some public sector bodies. Businesses using contractors or labour-only subcontractors should seek advice on whether those individuals count as "employees" for EL purposes — the courts apply a substance-over-form test.

2. Public Liability Insurance

Public liability (PL) insurancecovers a business's legal liability to pay compensation and costs if a member of the public — a customer, visitor, passerby, or any third party — suffers injury, death, or property damage as a result of the business's activities.

PL insurance is not compulsory by law (with limited exceptions, such as for riding establishments and certain licensed activities) but is commercially essential. A serious personal injury claim — for example, a customer slipping on a wet floor and sustaining a brain injury — can result in a multi-million pound award once future care costs and loss of earnings are included. Without PL insurance, such a claim could bankrupt a business.

Cover levels:

  • £1 million — minimum for most small retail and office-based businesses
  • £2–5 million — required by many local authority, NHS, and public sector contracts
  • £5–10 million — required for tradespeople, contractors, and businesses working on large construction or infrastructure projects

PL insurance does not cover injury to employees (that is EL's role), contractual liability (unless specifically added), or deliberate acts. Always review the exclusions carefully.

3. Professional Indemnity Insurance

Professional indemnity (PI) insurance(also called errors and omissions or E&O insurance) covers a business's legal liability for financial loss caused to clients by negligent advice, design, or professional services. It is essential for any business that provides advice, designs, or professional expertise — accountants, solicitors, architects, engineers, IT consultants, financial advisers, surveyors, and many others.

PI insurance is compulsory for many regulated professions: solicitors (SRA minimum £2M for most firms), architects (ARB requirement), financial advisers (FCA requirement), and chartered surveyors (RICS requirement). Even where not compulsory, most professional services contracts require PI cover as a condition of appointment.

Key concepts:

  • Claims-made basis: Most PI policies are claims-made — the policy in force when the claim is made (not when the negligent act occurred) responds. This means continuous PI cover is essential even after winding down a practice.
  • Retroactive date: The earliest date from which negligent acts are covered. Never switch insurers without ensuring the retroactive date is maintained.
  • Run-off cover: When a business closes or a sole trader retires, run-off (tail) cover provides protection for claims arising from historical work. Typically available for 6 years (limitation period for contract claims).
  • Aggregation: Check whether the limit applies per claim or in aggregate (i.e., for all claims in the policy year combined). A per-claim limit of £1M is very different from a £1M aggregate where multiple claims erode the available cover.

4. Product Liability Insurance

Product liability insurancecovers a business's legal liability for personal injury, death, or property damage caused by defective products it has manufactured, supplied, or imported. Under the Consumer Protection Act 1987, liability for defective products is strict — the claimant does not need to prove negligence, only that the product was defective and caused the loss.

Product liability cover is typically included within a public liability policy — both covers are commonly sold together as a combined PL/product liability policy. However, manufacturers, importers, and retailers should confirm that product liability is explicitly included and check the policy limit applies separately to products and public liability claims.

Post-Brexit considerations: Businesses importing goods into Great Britain from the EU (or elsewhere) are now treated as importers for the purposes of the Consumer Protection Act 1987 and bear the same strict liability as UK manufacturers. Review product recall cover if you import goods — the cost of recalling and replacing a defective product batch can be substantial and is not covered by standard product liability policies.

5. Commercial Property Insurance

Commercial property insurance covers loss or damage to business premises and their contents. The policy structure varies depending on whether the business owns or leases its premises.

  • Buildings insurance: Covers the cost of rebuilding the structure following damage from fire, flood, storm, impact, subsidence, and other insured perils. If you occupy leased premises on an FRI basis, the landlord will usually insure the building and recover the premium through the service charge — but tenants should confirm cover is in place and adequate.
  • Contents insurance: Covers stock, equipment, fixtures, fittings, and business assets. Ensure the sum insured is the full replacement value — new for old basis — not the depreciated or second-hand value.
  • Business interruption (BI) insurance: Covers loss of gross profit or revenue following an insured event that forces the business to close or reduce turnover. BI cover is often undervalued — ensure the indemnity period (the period over which loss is covered) is long enough to cover the time needed to rebuild or relocate. Two to three years is typical for businesses in rented premises; longer for owner-occupiers rebuilding from scratch.
  • Subsidence: Often excluded in flood-risk or mining areas, or subject to a high excess. Check the policy wording carefully if your property is in a high-risk area.

6. Cyber Insurance

Cyber risk is the fastest-growing category of commercial insurance. Any business that processes personal data, relies on IT systems, or accepts card payments is exposed. Cyber incidents include ransomware, data breaches, phishing, business email compromise, and system failure.

A standalone cyber insurance policy covers:

  • First-party losses: Incident response costs (forensic IT, legal, PR), system restoration, data recovery, ransomware response (negotiation and payment where legally permissible), and business interruption losses from a cyber event
  • Third-party losses: Legal defence and damages arising from data subject claims under UK GDPR, regulatory investigation costs (note: ICO fines themselves are uninsurable as a matter of public policy, but defence costs and legal advice are covered), and notification and credit monitoring costs for affected individuals

Key points when buying cyber cover:

  • Standard commercial combined policies typically exclude cyber losses — a separate cyber policy is required
  • Insurers increasingly require businesses to demonstrate baseline security hygiene (Cyber Essentials certification, MFA, patched systems) as a condition of cover
  • Check the policy covers social engineering fraud (e.g., CFO fraud / CEO fraud) — this is often excluded or sublimited
  • The war exclusion is contentious in cyber policies — ensure the policy is clear on coverage for state-sponsored attacks

7. Directors & Officers Insurance

Directors and officers (D&O) insurance protects individual directors, officers, and senior managers against personal liability for wrongful acts carried out in their management capacity. Under the Companies Act 2006 and insolvency legislation, directors face personal liability for: wrongful trading, breach of fiduciary duty, disqualification proceedings, HMRC investigations, employment tribunal awards, and regulatory enforcement.

D&O cover has three insuring clauses:

  • Side A: Covers individuals directly where the company cannot indemnify them (e.g., in insolvency)
  • Side B: Reimburses the company for indemnifying directors
  • Side C: Entity cover for securities claims (more relevant to listed companies)

D&O is particularly important for SME directors because — unlike large corporates — they may lack the corporate indemnities and legal resources to defend claims. Claims can arise from investors, creditors, regulators, employees, and even other directors. Premium for a typical SME D&O policy starts at around £500–£1,500 per annum.

8. Commercial Vehicle Insurance

Any motor vehicle used on a public road must have at minimum third party only (TPO) insurance under the Road Traffic Act 1988. This is the legal minimum; TPO covers liability to third parties (injury and property damage) but not damage to your own vehicle.

For business use, standard private car policies typically provide social, domestic, and pleasure (SDP) cover only. Business use — including travel between work sites, client visits, or use by multiple employees — requires a business use extension or a dedicated commercial vehicle policy.

Key commercial vehicle considerations:

  • Hire and reward: Carrying passengers for payment (taxis, private hire, couriers) requires specific hire and reward cover — not covered by standard business use extensions. PHV operators must comply with TfL or local licensing authority requirements.
  • Fleet policies: Businesses with 3 or more vehicles can access fleet insurance, which covers all vehicles under a single policy and typically provides any authorised driver cover (rather than named drivers), simplifying administration.
  • Goods in transit: A separate goods in transit policy is required to cover stock and equipment while in transit — vehicle policies typically cover the vehicle and third-party liability only, not cargo.

9. Trade Credit Insurance

Trade credit insurance (also called credit insurance or debtor insurance) protects businesses against the risk of customers failing to pay their invoices due to insolvency or protracted default. It is particularly relevant for businesses with significant B2B debtor books — manufacturers, wholesalers, and exporters.

Coverage types:

  • Whole turnover: Covers the entire customer ledger; the insurer monitors the creditworthiness of all buyers and sets credit limits. Most common policy structure.
  • Key account / single buyer: Covers exposure to one or a small number of large customers.
  • Export credit: The UK Export Finance (UKEF)— the UK's export credit agency — provides government-backed export credit insurance and guarantees for businesses that cannot obtain cover from the private market. UKEF's Export Insurance Policy (EXIP) covers political and commercial risks on export contracts.

Trade credit insurance pays out (typically at 90% of the debt) when the buyer is formally insolvent or has not paid within the agreed overdue period (usually 6 months). Premiums are typically 0.1–0.5% of insured turnover. Insurers may withdraw cover on individual buyers at short notice if their credit assessment deteriorates — businesses should not rely on credit insurance as a substitute for sound credit management.

10. How to Buy Business Insurance

The UK business insurance market offers a range of purchase channels:

  • Online comparison platforms (Simply Business, Covéa, Superscript) — well-suited for standard SME risks (PL/EL combined, tradespeople, micro-businesses). Quick, cheap, but limited to standard products.
  • Direct insurer websites (Hiscox, Markel, AXA Business) — suitable for straightforward risks, with strong online claims handling and coverage wording that is usually clearer than aggregator products.
  • Insurance brokers— FCA-authorised intermediaries who advise on cover, access markets not available direct (including Lloyd's of London specialist lines), and advocate for the client at claims time. Brokers are compensated by insurer commission (typically 10–20%) or a fee disclosed to the client. For complex, high-value, or unusual risks, a specialist broker will typically achieve materially better terms than a direct purchase.
  • BIBA (British Insurance Brokers' Association) — operates a free Find a Broker service (biba.org.uk) matching businesses with specialist brokers for unusual or complex risks.
  • Lloyd's of London— the world's specialist insurance market, accessed through Lloyd's brokers. Relevant for high-value or unusual risks that the standard market declines.

When reviewing any policy, read the policy wording (not just the schedule and summary) and pay particular attention to: exclusions, conditions precedent to cover (failure to comply defeats the claim), claims notification requirements, and sub-limits for specific perils.
