What is business insurance?

Business insurance, also known as commercial insurance, is a form of cover that can protect businesses from financial losses if unexpected events occur. Cover is available for all sorts of businesses, from one-man bands to large enterprises.

What does business insurance cover?

Cover can be tailored to your specific business needs. Policies commonly include cover for:

  • Injury, death or damage to property caused by your business

  • Sickness or injury to employees in the workplace

  • Third-party damages caused by your business

  • Business interruption

  • Damage to and theft of business property and equipment.

Legal requirements for business insurance can vary, depending on your business set-up.

  • Employers’ liability insurance is a legal requirement if you have any staff.

  • Professional indemnity insurance may be required by some regulators and industry bodies, such as financial advisors, solicitors, accountants, architects and surveyors. You may need it to work in other occupations too, including as a personal trainer, private doctor or nurse.

  • Public liability insurance isn’t typically a legal requirement, although contracts for your services may require you to have it.

Even where it’s not legally required, certain types of commercial insurance could protect you, your employees and anyone you deal with.

And the good news is, comparing quotes and getting the right cover for your business doesn’t have to be complicated.

FAQs

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.

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.
