Cover the risks that matter to your business

The best business insurance isn't the most cover — it's the right cover for how you operate. A consultant, a tradesperson and a shop owner need very different policies. Some cover is legally required; the rest depends on your risks. Here are the essentials.

1. Public liability insurance

Covers claims if your business injures someone or damages their property. Best for any business that interacts with the public, clients or their premises — often the foundation policy, and sometimes required by clients or contracts.

2. Professional indemnity insurance

Covers claims that your advice or services caused a client financial loss. Best for consultants, contractors, designers and anyone giving professional advice — often mandatory in professional sectors.

3. Employers' liability insurance

Legally required if you employ anyone (with very limited exceptions). Covers claims from staff who are injured or fall ill through work. Best — and compulsory — for any business with employees; fines apply for not having it.

4. Combined business insurance / business owner's policy

Bundles common covers (liability, contents, stock, business interruption) into one policy. Best for shops, offices and premises-based businesses wanting broad protection efficiently in a single package.

5. Sector-specific and add-on cover

Tools cover for tradespeople, cyber insurance, stock, equipment, and business interruption fill specific gaps. Best chosen selectively based on your real exposures — don't pay for what you don't need.

What does your business need?

  • Employ staff: employers' liability (legally required)
  • Deal with public/clients: public liability
  • Give advice/services: professional indemnity
  • Premises-based: a combined policy
  • Specific risks: add tools, cyber or business interruption cover
