What type of business insurance do I need?

If you’re unsure what kind of insurance your small business needs, you’re not alone.

In fact, 51% of businesses stopped buying at least one form of insurance cover.

And even when they do buy it, business owners only realise they’re underinsured when something goes wrong. Some insurance is legally required, others are optional but can still save your business from a disaster.

This guide will help you understand the different types of business insurance you need and how to choose the right policy without overpaying.

Start by understanding your risks

First things first. Before you ask what insurance you need, you should ask yourself what could go wrong.

Identifying your risks is the most important step in finding the right protection. A simple assessment can help you spot the weak points and break down the risks you face. These usually fall into three categories: physical, legal and digital.

  • Physical risks include things like workplace injuries, property damage and equipment failure. If you own a shop, a flood could wipe out your stock. If you’re a builder, faulty equipment could cause a serious injury. These risks are often the most visible and usually the most expensive when they go wrong.
  • Legal risks come from contracts, employment law and regulations. A customer might sue over allegedly incompetent advice. A former employee could take you to tribunal. Many of these risks seem invisible until they happen, but can cost you time and money fast.
  • Digital risks are rising for every business. From lost data to ransomware attacks, even small businesses are now prime targets of cybercrime.  If you hold sensitive customer information or use cloud-based services, you’re vulnerable to attacks.

It’s always worth reviewing your cover as your business changes. A policy that suited you three years ago might now leave critical gaps. Keeping your insurance up to date ensures you’re not caught out when things go wrong.

Match insurance types to your business risks

Once you’ve mapped out the risks your business faces, you can start to think about which insurance policies you need, which we can help with. Here are the main types of business insurance, what they cover and who they’re for.

1. Commercial property insurance

If you own the building your business operates from, commercial property insurance protects you against damage to the premises from unexpected events like fire, flooding or vandalism.

What commercial property insurance covers

  • Repairs or rebuilding costs if your building is damaged.
  • Damage from fire, storms, flooding or burst pipes.
  • Vandalism or malicious damage to the building.
  • Accidental damage to walls, roofs, doors and fixed structures.

This cover is essential for property owners and landlords as it can often be a key business asset.

2. Employers’ liability insurance

If you employ anyone, you’re legally required to have this cover. It protects your business if an employee is injured because of their work. This includes physical accidents and long-term health issues, most commonly as a result of trip, slips and falls in the workplace.

What employers’ liability insurance covers

  • Compensation payments if an employee is injured or falls at work.
  • Legal defence costs if you’re taken to court.
  • Medical fees and rehabilitation expenses tied to a workplace injury.
  • Incidents involving full-time, part-time, casual or temporary workers.

If you don’t have this cover when legally required, you could face fines of up to £2,500 for each day you’re uninsured. You must also display the EL certificate or risk another £1,000 fine.

It’s always worth double checking if you need it, including if you’re unsure.

3. Public liability insurance

 

This cover protects you if someone outside your business suffers an injury or property damage because of your business activities. It’s one of the most common types of insurance for small businesses, especially those who deal with people face to face.

What public liability insurance covers

  • Compensation claims if someone is injured on your premises.
  • Damage to someone else’s property while you’re working.
  • Legal defence costs if a claim is made against you.
  • Incidents that happen off-site, like at a client’s home or a public event.

Many clients, landlords or local councils will ask for proof of cover before working with you. For retail, trades, events, and personal services, this policy is often required.

 

4. Professional indemnity insurance

 

If your business gives advice, provides a service or handles sensitive information, this protects you if a client claims your work caused them financial loss.

What professional indemnity insurance covers

  • Compensation if your advice or services cause a client to lose money.
  • Legal defence costs if you’re accused of negligence or breach of contract.
  • Claims of breach of confidentiality or misuse of client data.
  • Unintentional intellectual property infringement (like using a copyrighted image).

This cover is especially important for consultants, accountants, IT providers and others in professional services. It’s also often required by professional bodies and regulators.

 

5. Cyber insurance

 

If your business stores customer data, relies on digital systems, or takes online payments, cyber insurance helps protect you from the financial impact of data breaches and cyberattacks.

What cyber insurance covers

  • Recovery costs for lost data and damaged IT systems.
  • Legal and regulatory costs after a data breach.
  • Cyber extortion demands, like ransomware.
  • Business interruption caused by system outages.

Cyber threats affect businesses of all sizes. This cover is increasingly important even for small businesses, especially if you handle personal information or depend on cloud services.

Choosing the right type of business insurance

The type of insurance you need depends on how your business operates, combining business types to suit your business. It’s not about ticking every box, it’s about getting the right cover for your actual risks.

Start by reviewing:

  • Whether you employ staff or work alone
  • If customers visit your premises or you work off-site
  • Whether you give advice or provide a professional service
  • If you store data, sell online or rely on digital systems
  • Whether you own your business premises, tools or stock

The answers to these questions shape your insurance needs. Choosing cover that fits your business means you won’t waste money on things you don’t need, or leave yourself exposed where it matters most.
