Having the right types of business insurance is essential to protect your company’s financial health and reputation. Understanding which policies are legally required and which offer valuable protection can save you from costly surprises down the line.
| Type of Business Insurance | What It Covers | Legal Requirement | Typical Cost Range (UK Small Business) |

Employers' Liability Insurance
If your business employs anyone, even on a casual or part-time basis, employers' liability insurance is a legal requirement in the UK. This insurance covers you if an employee or former employee makes a claim for injury or illness caused by work-related activities. It can include compensation for medical costs, lost wages, and legal fees.
You must have a minimum of £5 million in cover, although many businesses opt for £10 million or more depending on their sector and risk profile. Failure to have this insurance can result in fines of up to £2,500 per day and even prosecution. You must also display your insurance certificate where employees can see it or provide it to them upon request.
Public Liability Insurance
While not legally required, public liability insurance is often essential for businesses that interact with the public, customers, or other third parties. It protects your business against claims for injury or property damage caused by your business activities — for example, if a customer slips on your premises or if your work damages a client’s property.
Public liability insurance can cover legal costs and compensation payments, which might otherwise be financially devastating. Many clients and contracts, especially in construction, hospitality, or events, will require you to have this insurance before working with you.

Professional indemnity insurance (PII) is crucial if your business provides advice, consultancy, or professional services. It protects you if a client claims that your advice or work caused them financial loss due to negligence, errors, or omissions.
Certain regulated professions, such as architects, accountants, solicitors, and financial advisers, are required by industry bodies or law to carry PII. Even where not mandatory, having PII can reassure clients and help you win contracts.
Who Needs Professional Indemnity Insurance?
Businesses that typically require PII include:
- Consultants and freelancers offering expert advice
- Architects and engineers involved in design
- IT and software developers
- Marketing agencies and creative professionals
- Financial advisors and accountants
Business Interruption Insurance
Business interruption insurance covers loss of income and extra costs incurred if your business cannot operate due to an insured event, such as fire, flood, or other damage to premises or equipment. This policy helps maintain cash flow and pay fixed costs like rent and salaries while you recover.
Unlike other insurances, business interruption cover is usually an add-on or part of a wider commercial property insurance policy. You should carefully assess your potential loss period and sums insured with your broker to avoid underinsurance.
Cyber Insurance
With increasing digital threats, cyber insurance has become a vital protection for UK businesses of all sizes. It covers costs arising from data breaches, ransomware attacks, loss of sensitive information, and related legal liabilities. Policies often include crisis management, IT forensics, notification costs, and regulatory fines (where insurable).
Though not legally required, cyber insurance is highly recommended, especially if you store customer data or conduct business online. The UK government’s National Cyber Security Centre provides guidance on cyber risks tailored for small businesses.
Other Types of Business Insurance
Depending on your business sector and activities, you may also consider:
- Commercial Property Insurance – Covers physical assets like buildings, stock, and equipment.
- Vehicle Insurance – Required if you use vehicles for business purposes.
- Directors and Officers (D&O) Insurance – Protects company leaders against claims related to their management decisions.
- Product Liability Insurance – Covers claims from defective products causing injury or damage.
Choosing the right insurance mix depends on risk assessment, industry standards, and legal obligations.
- Employers' liability insurance is legally required if you have employees.
- Public liability insurance is essential for businesses interacting with the public or clients.
- Professional indemnity insurance protects against claims of professional negligence and is mandatory for some professions.
- Business interruption and cyber insurance provide valuable protection against income loss and digital threats, respectively.
- Regularly review your insurance portfolio as your business grows or changes.

Is employers' liability insurance compulsory for the self-employed?
No, if you are genuinely self-employed with no employees, you are not legally required to have employers' liability insurance. However, if you hire staff or subcontractors, this insurance becomes mandatory.
How much public liability insurance cover should a small business have?
Most small businesses opt for cover between £1 million and £5 million, depending on their exposure to risk and client requirements. Some contracts may require higher limits, so always check before agreeing to work.
Can I get business insurance if I work from home?
Yes, many insurers offer policies tailored for home-based businesses. It’s important to disclose your working location, as standard home insurance usually does not cover business activities or equipment.
