What is business insurance?

Business insurance (also known as commercial insurance) helps protect your business against financial losses caused by unexpected events.

It’s available for most types of businesses, from sole traders to large enterprises.

What are the main types of business insurance?

The most common types of business insurance are public liability insurance, employers’ liability insurance, and professional indemnity insurance. Here’s how they work:

Public liability

  • tick

    Covers claims if your business injures a member of the public

  • tick

    Protects against damage to someone else’s property

  • tick

    Some customers may require public liability cover before working with you

Employers’ liability

  • tick

    Covers compensation claims if an employee is injured or becomes ill at work

  • tick

    Helps protect your business against legal and compensation costs

  • tick

    Employers’ liability cover is usually a legal requirement if you employ staff

Professional indemnity

  • tick

    Covers claims if your business harms a client’s finances or reputation

  • tick

    Helps recover compensation costs and related legal fees

  • tick

    Professional indemnity insurance can protect your business against costly professional mistakes

Why

Employ staff

Employers’ liability insurance

It’s a legal requirement (with limited exceptions, such as some family businesses).

Deal with customers or the public

Public liability insurance

Covers legal fees and compensation if someone is injured or their property is damaged because of your work. Not legally required, but many councils won’t work with you without it.

Give advice, a service, or expertise a client relies on

Professional indemnity insurance

Covers claims and legal fees if a mistake you make harms a client’s finances or reputation. Not a legal requirement, but often expected by clients or professional bodies.

Belong to a professional or trade body

Cover as specified by that body

Some bodies make certain cover a condition of membership.

Bear in mind...

Employers' liability insurance isn't optional if you have staff – it's a legal requirement.

What our expert says...

"When comparing quotes, don’t just focus on the cheapest business insurance policies. Getting the right cover is vital to protecting you, your staff and your company. It’s important you’re aware of the types of cover that are legally required, and which are optional.

"Whether you’re a one-person operation, a large office or a hands-on manufacturer, there’s protection for all the risks your business faces."

How much business insurance do I need?

The level of insurance you need for your business will depend on the size and nature of your business, and what you want cover for. Think about the everyday risk involved with the type of work you do and what you need to be protected against.

For example, a plumber insurance policy will cover very different risks to an electrician insurance policy, so it's worth thinking about what's specific to your trade as well as your business more broadly.

Consider whether you:

  • Deal with members of the public

  • Are a sole trader or an employer

  • Have business premises

  • Use a vehicle for your work

  • Have stock or work tools and equipment

  • Offer a product, trade or a service

  • Need business interruption insurance.

What other types of business insurance are there?

Other common types of cover include product liability, commercial insurance, landlord insurance, business interruption, key person cover, tool cover, cyber risk insurance, business vehicle insurance, and D&O insurance. Find out the basics of each below.

Product liability insurance

Offers protection against compensation pay-outs and legal costs if someone is injured or their property is damaged by a product you sold them. This is often added as a paid-for extra to public liability insurance.

Commercial buildings and contents insurance

Business contents insurance could protect your business premises and its contents if they’re damaged because of flood, theft or fire.

Landlord insurance

Typically protects you if your rental property is damaged. You can also include protection against loss of earnings due to an incident you’re insured for: burst pipes, for example.

Learn more about landlord insurance.

Business interruption insurance

Can offer protection if something prevents you from trading – for example, if your business premises are damaged by a flood, storm or fire.

Key person cover

Also known as key man insurance, this can protect you from financial impact if someone essential to your business dies or is diagnosed with an illness listed in the policy.

Tool cover

You can also cover tools, equipment and stock in case they’re damaged or destroyed.

Cyber risk insurance

This can protect you from losses caused by damage to your IT systems or loss of information from them.

You can’t compare cyber risk insurance with Compare the Market.

Business car or business van insurance

If you own vehicles that you use for your business, you’ll need to have business car or business van insurance.

Directors’ and officers’ (D&O) insurance

Also known as management liability insurance, this could cover the cost of defending and paying out personal claims made against directors and chief officers of your business.

It could cover the key managers in your company against alleged wrongful acts, such as breach of duty or making misleading statements.

Tailored business insurance for small business and trades

Every business is unique and faces different risks. Tailored business insurance is customised to help ensure you’re covered for the risks that are specific to your trade.

FAQs

Is business insurance a legal requirement?

Business insurance isn’t always legally required, but some types are mandatory depending on your business.

If you employ staff, you’re legally required to have employers’ liability insurance.

In certain regulated industries, such as financial services, law, accountancy, architecture and surveying, you may also be required to hold professional indemnity insurance by your regulator or professional body.

Public liability insurance isn’t usually a legal requirement, but many clients and contracts will expect you to have it in place.

Will changing from sole trader to limited company affect my business insurance policy?

Yes, the legal structure of your business will change, so you’ll need to contact your insurance provider. It will most likely cancel your existing policy and replace it with a new one that covers your change of company status. The price of your premium might also change.

Do I need business insurance for an online business?

Yes, online businesses still need business insurance because they face risks such as stock loss, cyber-attacks or legal obligations if they employ staff. 

If you have employees, you’re legally required to have employers’ liability insurance (unless they’re immediate family). 

Cyber insurance can also help protect against malware or ransomware attacks, covering financial losses, data theft and compensation costs to any third-parties whose data is affected. 

Does business insurance cover theft?

Business insurance can cover theft, but it depends on what’s stolen and what insurance cover you have. 

  • Business equipment insurance could cover against the theft of laptops stolen from your office, for example.

  • Stock insurance could help cover the theft of valuable stock, as well as accidental damage. It could also cover losses caused by dishonest employees.

When should I get business insurance?

As with most types of insurance, it's usually better to get cover sooner rather than later. You can even get insurance before you start trading.

If your business needs a trade licence – you might be running a pet shop, a pub or a taxi service – you can sort out your insurance before you get your licence.

You may also need insurance for your business premises as soon as you exchange on the property, even if your licence hasn’t yet been granted.

Note that it will be a requirement of your business insurance policy that all necessary licences are in place before you start trading. If you start trading without them, any claim you make could be rejected.

Can I get business insurance before registering my business?

Yes, you can get business insurance before registering your business and even before you’ve started trading.

When you buy business insurance, you won’t usually be asked for your company registration number or any other business registration details. But you’ll typically be asked your business address, your trade type and your actual or projected turnover.

You could also be asked how your business is set up (whether you’re a sole trader or a limited company, for example).

Is business insurance tax-deductible?

Business insurance is usually considered an allowable expense if it’s wholly and exclusively for business use. Other costs, such as business broadband and business energy, are also tax-deductible, as long as they’re exclusively related to your business.

If you’re not sure, ask HMRC or your accountant or tax advisor. Keep your receipts and policy documents safe and make sure any claimable insurance costs are included in your tax return.

Do I need business insurance if I’m self-employed?

You may need business insurance if you’re self-employed, especially if you employ staff, provide professional advice or services, handle client data, or could be held responsible for injury or property damage.  

In many cases you can claim your business insurance as a tax-deductible expense. 

Can I add cover for a different trade to my business insurance policy?

When you start a quote with us, you’ll have the option to add a secondary trade to your policy. You’ll be able to choose from more than 1,000 options to describe your trade.

Lines are operated by our trusted partner Simply Business and are open Monday, Tuesday, Wednesday and Friday 9am-5.30pm, Thursday 9.30am-5.30pm and Saturday 9am-2pm.

Can I still get business insurance if I’ve had CCJs or IVAs?

If your business has suffered debt problems and you’ve had a County Court Judgement (CCJ) or Individual Voluntary Arrangement (IVA), you may still be able to get business insurance.

But you might have fewer options and may need to find a broker who specialises in business insurance if you have bad debts or bankruptcy issues.
