Business insurance is one of those things most small business owners know they need but often put off sorting properly. The result is either being underinsured (a serious risk) or paying for cover you don't need. This guide cuts through the jargon and tells you exactly what cover a UK small business needs.
Legally Required Insurance
Only two types of business insurance are legally required in the UK:
Employers' Liability Insurance
Required if: You employ anyone, including part-time staff, temporary workers, and most contractors.
Minimum cover: £5 million (most policies provide £10m)
Penalty for non-compliance: Up to £2,500 per day
Motor Insurance
Required if: You use a vehicle for business purposes (including driving to client sites in your personal car).
Note: Standard personal motor insurance does NOT cover business use — you must add it.
Penalty: Driving without valid insurance is a criminal offence.

Insurance and Tax
Business insurance premiums are generally a tax-deductible expense — meaning you can offset the cost against your taxable profits. This applies to:
- Public liability insurance
- Professional indemnity insurance
- Employers' liability insurance
- Business contents insurance
- Cyber insurance
However, life insurance and income protection policies taken out personally (not through the business) are generally not deductible. Always check with your accountant for your specific situation.
Accounting tip
If you pay an annual insurance premium, your accounting software should spread the cost across the months it covers (prepayment treatment). This gives you a more accurate monthly profit figure. Most modern software handles this automatically.
Common Mistakes to Avoid
Using personal insurance for business activities
Always check your policy covers business use — especially for vehicles and home office equipment.
Underinsuring business contents
Insure for replacement value, not market value. Computers depreciate fast but cost full price to replace.
Forgetting to update cover as you grow
Review your insurance annually — new employees, new equipment, and new services all change your risk profile.
Not reading the exclusions
Cheap policies often have significant exclusions. Read the policy wording, not just the summary.
