What Insurance is Legally Required for Businesses?

In Short

  • Some insurance is legally required in the UK, including employers’ liability, motor insurance and, for certain professions, professional indemnity cover.

  • Optional insurance can still be critical for protecting your finances, meeting client expectations and keeping your business trading during disruptions.

  • Reviewing your insurance regularly helps ensure it matches your risks as your business grows or changes.

Tips for Businesses

Take time to assess what your business actually does and the risks that could realistically arise. Check which insurance is legally required, then consider additional cover that clients or partners may expect. Speaking to an insurance broker can help you choose suitable policies and review them as your business evolves.

Running a business will inevitably involve some element of risk and, therefore, requires strong planning and preparation for unexpected or high-risk events. Insurance is a very important risk prevention tool; without it, your business could face significant problems and costs. 

In some circumstances, the consequences of not having appropriate insurance in place can be catastrophic for a business. Business owners must understand which types of insurance are legally required and how extra cover can help protect the business. In practice, both mandatory and optional insurance policies are often essential for a business that is actively trading.

This article explores:

  • mandatory insurance requirements;
  • why additional insurance cover can strengthen business resilience; and
  • how to understand the types of cover your business needs for risk prevention. 

Why Is Insurance Important for Businesses?

Insurance is an important way to protect your business financially if something goes wrong. Without the right cover, a single incident, such as an employee injury or professional mistake, can lead to high or even unmanageable costs.

When you have appropriate policies in place, you can: 

  • recover costs more quickly; 
  • manage liabilities effectively; and 
  • trade with greater confidence.

Certain types of insurance are mandatory. Depending on your trading activities, insurance can also help you meet the expectations of clients, suppliers and certain regulatory bodies, many of whom require businesses to hold specific types of cover. 

You should review your insurance coverage regularly to ensure your policies continue to align with your operational risks and remain effective in adequately protecting your business.

Which Forms of Insurance Are Legally Required?

In the UK, some types of insurance are legally required. Employers’ liability insurance is a key requirement for many businesses. If you employ staff in any capacity, you must typically have this cover in place. This insurance protects your business if an employee becomes ill or injured because of their work, as it helps cover compensation costs.

Without it, you can face fines of up to £2,500 for each day you are uninsured.

Motor insurance is also compulsory when your business uses vehicles on public roads. As such, you must ensure that any vehicle used for work is appropriately insured. 

Some regulated professions have extra insurance requirements. For example, professional indemnity insurance is essential for people providing regulated services such as legal, accounting, or financial services. In these sectors, holding this insurance is a condition of being allowed to practise. It helps protect clients if professional advice or services cause loss.

Which Other Insurance Policies Could My Business Benefit From?

Although most business insurance is optional, several policies are still important for protecting your long-term stability. Many clients, business partners, or investors may ask to see proof of these insurance policies before working with you or discussing opportunities.

Some examples of important cover include: 

  • Professional indemnity insurance helps a business defend itself if a client alleges that the advice or services caused them financial loss – even if you are not regulated and do not require such cover. 
  • Public liability insurance protects you if a member of the public suffers injury or property damage connected with your activities.  
  • Business interruption insurance can stabilise your cash flow when an unforeseen event prevents you from trading as usual.
  • Cyber insurance has become increasingly valuable as businesses rely more heavily on digital systems

These policies can significantly reduce the financial and operational consequences of unexpected disruptions.

Commercial Value of Insurance in Contracts and Due Diligence

Businesses often value insurance not only to manage risk, but also to support their commercial position. Clients and partners increasingly expect organisations to have appropriate insurance in place before entering into contracts or starting work, and in many sectors this is seen as a sign of professionalism and reliability.

During due diligence, especially where you act as a data processor under the UK GDPR, customers may ask for proof of insurance and expect you to hold policies such as cyber insurance.

Even where the law does not require specific cover, having the right insurance can be important for winning work and showing that your business can manage risk.

How Can You Decide on Appropriate Insurance and Coverage?

Choosing suitable insurance can be challenging, especially as policies often contain detailed terms, conditions and exclusions. A sensible starting point is to: 

  • assess the activities your business performs; 
  • identify the risks that could realistically arise; and 
  • research or seek advice on whether insurance is mandatory for you or the best practice.

Many organisations choose to speak with an insurance broker, who can evaluate your risk profile, explain your options and recommend policies that align with your operational needs. As your business develops and changes over time, you should remember to review your policies to ensure that your coverage remains appropriate for your risk profile.

Frequently Asked Questions

How can I find out which insurance my business needs?

You can determine your insurance needs by: checking the legal requirements that apply to your business; reviewing any regulatory rules that govern your profession; and considering the contractual and commercial expectations of your clients and suppliers.  An insurance broker can help you by assessing your trading operations, explaining the risks involved and recommending cover that offers suitable protection.

Is insurance a commercial expectation for suppliers?

Many organisations expect suppliers to hold appropriate insurance before they agree to work with them, and may request evidence of cover during onboarding or due diligence. Even where no legal requirement exists, maintaining suitable insurance can strengthen your credibility, support contract negotiations and demonstrate that you take risk management seriously.
