How small business insurance works in the UK

Small business insurance is rarely a single product. Most policies are packaged, letting an owner combine the covers their trade needs into one schedule. The common building blocks are public liability for third-party injury or damage, employers' liability where staff are employed, professional indemnity for advice-led work, and property covers for premises, stock, contents, and business interruption. GOV.UK confirms that employers' liability is the cover most often required by law, with a legal minimum of £5 million.

The compulsory element matters most. Under the Employers' Liability (Compulsory Insurance) Act 1969, a business with employees must hold employers' liability cover, and GOV.UK states a fine of £2,500 for each day a business is not properly insured, plus £1,000 for failing to display the certificate. Public liability, by contrast, is not generally compulsory but is widely required by clients and contracts, which is why the ABI records it as the most commonly held SME cover.

Every insurer underwriting business cover in the UK must be authorised by the Financial Conduct Authority. Buyers can confirm authorisation on the FCA Register at register.fca.org.uk, and the Financial Ombudsman Service can review eligible complaints from consumers and smaller businesses if a claim is declined and the insurer's complaints process is complete.

How to compare small business insurance objectively

Start with what the law requires. If you employ staff, employers' liability is compulsory with a £5 million minimum, and the certificate must be displayed. Build the rest of the package around the actual risks of your trade, rather than buying sections you do not need.

Match limits to your contracts and assets. Public liability limits are often dictated by client contracts, while property and stock sums insured should reflect full replacement values to avoid underinsurance, which the ABI highlights as a common reason claims are paid only in part.

Check the exclusions and whether advice-led work needs professional indemnity. Then verify the insurer or broker on the FCA Register before buying. If a claim is later declined and you disagree, eligible complaints can be escalated to the Financial Ombudsman Service once the insurer's complaints process is complete.

Frequently asked questions

What insurance does a small business legally need in the UK?

If you employ staff, employers' liability insurance is compulsory with a legal minimum of £5 million under the Employers' Liability (Compulsory Insurance) Act 1969. Most other covers, including public liability, are not legally required but are often demanded by clients or contracts.

What is usually included in a small business insurance package?

Packages commonly combine public liability, employers' liability where staff are employed, professional indemnity for advice-led work, and property covers such as contents, stock, and business interruption. Owners select the sections their trade needs.

What happens if I do not have employers' liability insurance?

GOV.UK states a business can be fined £2,500 for every day it is not properly insured for employers' liability, and £1,000 for failing to display the certificate where employees can see it.

How much public liability cover should a small business have?

There is no legal minimum, but many client contracts and public bodies require £5 million or £10 million. Check your contract terms, as limits are fixed per claim period and under-buying can leave a gap.

How do I check a business insurer is authorised?

Search the firm on the FCA Register at register.fca.org.uk. The Register confirms authorisation and the activities a firm is permitted to carry out. All the insurers in this guide are FCA-authorised.

What can I do if a business insurance claim is rejected?

Use the insurer's internal complaints process first. If you remain dissatisfied, an eligible small business can refer the complaint to the Financial Ombudsman Service for a free, independent review.
