Whether you're launching a startup or running an established company, navigating the insurance landscape can feel overwhelming. Yet the right protection can make the difference between minor setbacks and business-ending disasters.
This guide breaks down exactly what you need to know about small business insurance in the UK for 2025, helping you protect your company without overspending on unnecessary coverage.
What Insurance Is Required by Law in the UK?
Unlike many business expenses, certain insurance policies aren't optional for UK small businesses. The law specifically mandates one type of insurance coverage, with significant consequences for those who fail to comply.
Employers' liability insurance explained
Employers' liability insurance (EL) is the only legally required insurance for most UK businesses that employ staff 1. This policy protects your business if an employee becomes ill or suffers an injury due to their work and makes a claim against you. The coverage extends to compensation costs and legal fees associated with defending such claims.
By law, your employers' liability policy must provide coverage of at least £5 million 2. Some insurers, such as AXA, offer standard coverage of £10 million 3. Furthermore, you must purchase this insurance from an authorised provider registered with the Financial Conduct Authority (FCA).
This requirement applies to all employees with an expressed or implied contract, even oral agreements. This means if someone is working for you, you need this insurance—regardless of whether formal paperwork exists 3.
The legal requirement extends to businesses employing:
- Full-time and part-time staff
- Temporary workers
- Labour-only subcontractors working under your direction
- Apprentices
- Work experience students
Penalties for not having legal cover
The financial consequences of operating without proper employers' liability insurance are substantial. For each day your business operates without appropriate coverage, the Health and Safety Executive (HSE) can fine you up to £2,500 1. Consequently, even a brief period without insurance could result in significant penalties.
Additionally, you must prominently display your Employers' Liability Certificate where employees can easily access it. Failure to make this certificate available to HSE inspectors upon request carries a separate fine of up to £1,000 2.
Beyond the legal penalties, operating without this insurance leaves your business financially vulnerable. If an employee makes a successful claim against you without insurance protection, you'll be personally responsible for all compensation and legal costs—potentially threatening your business's survival.
Exceptions for family-run businesses
Although employers' liability insurance is mandatory for most businesses with employees, certain exemptions exist. The primary exception applies to family businesses that exclusively employ immediate family members—but only if the business is not incorporated as a limited company 3.
For this exemption, 'immediate family' is specifically defined as:
- Spouse or civil partner
- Parents and grandparents
- Children and grandchildren (including stepchildren)
- Siblings (including half-siblings)
However, this exemption does not apply to incorporated limited companies, even if they only employ family members 3. Additionally, if your limited company employs only you as the owner, and you hold at least 50% of the shares, you may not need employers' liability insurance 4.
Other exemptions may apply to public organisations, health service bodies, and businesses employing workers who aren't ordinarily resident in the UK—though specific conditions apply 5.
Despite these exceptions, many insurance experts recommend considering employers' liability insurance even when not legally required, as it provides valuable protection against potentially costly claims.
Essential Insurance Types for Small Businesses
Beyond legal requirements, certain insurance policies serve as fundamental protection for small businesses in the UK. While not mandatory, these insurance types shield your business from financial risks that could otherwise prove devastating.
Public liability insurance
Public liability insurance (PL) protects your business when a member of the public suffers injury or property damage because of your business activities. This policy covers legal fees and compensation costs that could otherwise run into millions of pounds.
PL insurance applies both on your premises and when working off-site. For example, if a customer visits your premises and slips on a wet floor, suffering serious back injuries, your public liability insurance would cover the resulting claim.
Moreover, many clients and suppliers may require you to have PL insurance as a condition of working with them. This makes it a vital consideration for almost any business that interacts with customers, clients, or the general public.
Most policies start at around £1 million coverage, but you can purchase up to £10 million or more depending on your business needs. According to industry data, the average premium for public liability insurance between July and September 2024 was £95.07 per year.
Professional indemnity insurance
Professional indemnity insurance (PI) protects businesses that offer professional services or advice. If you make a mistake or a client suffers financial loss because of your work, PI insurance covers legal and compensation costs.
This insurance type is particularly valuable for:
- Architects and surveyors
- Accountants and financial advisers
- IT consultants
- Marketing professionals
- Business consultants
Professional indemnity insurance covers various scenarios, first thing to remember is that it protects against professional negligence claims. It also covers defamation, breach of confidence, breach of copyright, and lost or damaged documents.
While not legally required for most businesses, PI insurance may be compulsory for certain professions. For instance, accountants, architects, and surveyors must have this cover to join their respective professional bodies. Likewise, clients often require PI insurance as part of their contract conditions.
The cost of professional indemnity policies starts from between £80 and £100 per year, with coverage levels typically ranging from £2 million to £5 million.
Product liability insurance
Product liability insurance protects your business against claims of injury or damage caused by products you design, manufacture, or supply. This coverage is essential for businesses making or selling physical products.
Remarkably, you can be held liable for faulty products even if you didn't manufacture them. You may be liable if:
- Your business name appears on the product
- You repair, refurbish or modify a product
- You import the product from outside the European Union
- The manufacturer cannot be identified or has gone out of business
Product liability insurance covers claims of personal injuries and property damage caused by your products. It also protects against unforeseeable circumstances such as product faults that your quality control system couldn't identify.
Nevertheless, this insurance generally doesn't cover faulty products resulting from poor workmanship or financial losses to businesses caused by your defective product.
Most businesses take out product liability policies covering compensation claims between £1 million and £5 million, ensuring adequate protection against potentially costly claims.
