Do I Need Insurance to Run a Small Business

Running a small business involves taking on a range of responsibilities and risks. Even if you operate on a small scale, things can go wrong — from accidents at work to client disputes or equipment damage. Business insurance helps protect you financially and legally if the unexpected happens. This guide explains what types of insurance are required by law and which policies are worth considering for your small business.

At Towerstone Accountants we provide specialist small business accountancy services for owners, directors, and growing businesses across the UK. We created this webpage for small business owners who want clear guidance on managing finances, meeting tax obligations, and making informed decisions without jargon. Our aim is to help you stay compliant, improve cash flow, and build a more resilient business.

This is one of the most common questions I hear from people starting or running a small business, and it is also one of the most misunderstood. Many business owners assume insurance is either optional, overly expensive or something they can think about later once the business is more established. Others worry that they are legally required to take out every type of policy available, which can feel overwhelming and unnecessary.

In reality, business insurance in the UK sits somewhere between these two extremes. Some types of insurance are legally required, some are strongly advisable and others depend entirely on how your business operates, who you deal with and the level of risk you are exposed to. The challenge for many small business owners is understanding which is which and how to make sensible decisions without overspending.

In this article, I want to explain clearly and practically whether you need insurance to run a small business, which types of insurance are compulsory, which are optional but sensible and how to think about insurance as part of running a sustainable business. This is written from a UK perspective and based on real situations I see regularly, not worst case scare stories or sales driven advice.

The short answer to whether you need insurance

Strictly speaking, not every small business in the UK is legally required to have insurance. However, most businesses either must have certain cover by law or would be taking an unnecessary and potentially serious risk by operating without it.

The real question is not do I need insurance, but rather what level of risk am I willing and able to carry myself. Insurance exists to protect you from risks that could otherwise wipe out your business, your personal finances or both.

When insurance is legally required

There are only a small number of insurance types that are legally compulsory in the UK, but they are important.

Employers’ liability insurance

If you employ anyone, even part time or casually, you are legally required to have employers’ liability insurance. This applies whether your staff are permanent, temporary or on zero hours contracts.

Employers’ liability insurance covers you if an employee is injured or becomes ill as a result of working for your business. This could include accidents, repetitive strain injuries or long term health issues linked to their role.

The law requires a minimum level of cover, and failure to have it can result in fines. Even if you think the risk is low, the legal requirement is absolute.

There are very limited exceptions, such as businesses that only employ close family members, but these should be checked carefully before assuming you are exempt.

Motor insurance for business vehicles

If you use a vehicle for business purposes, you must have appropriate motor insurance. Standard personal motor insurance often does not cover business use.

This applies whether the vehicle is owned by the business or personally owned but used for work. Using the wrong type of cover can invalidate your policy, leaving you exposed if there is an accident.

When insurance is not legally required but strongly advisable

Many of the most important types of business insurance are not legally required, but operating without them can leave you exposed to significant financial risk.

Public liability insurance

Public liability insurance is one of the most common types of cover for small businesses. It protects you if a member of the public is injured or their property is damaged as a result of your business activities.

This could include a customer slipping on a wet floor, damage caused while working at a client’s premises or an accident involving equipment you use.

While not legally required, public liability insurance is often essential in practice. Many clients, landlords and venues will not work with you unless you have it. In some industries, it is effectively a requirement even if not written into law.

Professional indemnity insurance

Professional indemnity insurance is relevant if you provide advice, services or professional expertise. It covers you if a client suffers financial loss as a result of an error, omission or negligence in your work.

This is particularly relevant for consultants, accountants, designers, IT professionals and anyone whose work influences decisions or outcomes.

Again, it is not always legally required, but many clients insist on it and the potential costs of a claim can be substantial.

Product liability insurance

If you manufacture, supply or sell products, product liability insurance covers you if those products cause injury or damage.

This applies whether you make the products yourself or source them from elsewhere. Even if a fault originates with a supplier, you may still face a claim from a customer.

For many retail and manufacturing businesses, this cover is essential.

Business property and contents insurance

If your business owns equipment, stock or operates from premises, insurance can protect against loss from fire, theft or damage.

For home based businesses, it is important to check whether your household insurance covers business use. In many cases, it does not or only provides limited cover.

Why small business owners often underestimate risk

One of the reasons insurance is often overlooked is that many risks feel remote or unlikely, particularly when a business is small.

In my experience, issues tend to arise not from dramatic events but from relatively ordinary situations. A minor accident, a dissatisfied client or a misunderstanding can escalate quickly and become expensive.

Small businesses are often more vulnerable because they lack financial buffers. A single claim or legal dispute can cause cash flow problems or force a business to close.

Insurance does not prevent problems, but it provides a safety net when they occur.

How to think about insurance sensibly

Insurance decisions should be proportionate. You do not need every policy available, but you do need to understand your specific risks.

A useful way to think about this is to consider:

  • Who could be affected by my business activities

  • What could realistically go wrong

  • What would the financial impact be if it did

If the potential cost of something going wrong is more than you could comfortably absorb, insurance is usually sensible.

Industry specific considerations

Different industries face different risks, and insurance needs vary accordingly.

For example:

  • Tradespeople often need public liability and tool insurance

  • Consultants and advisers often need professional indemnity cover

  • Retailers need product liability and stock insurance

  • Businesses with premises need buildings and contents cover

There is no one size fits all approach. This is why generic advice can be misleading.

Clients and contracts often dictate insurance

Even where insurance is not legally required, it may be required contractually.

Many clients include insurance requirements in contracts, particularly larger organisations or public sector bodies. If you cannot meet those requirements, you may lose work opportunities.

This is another reason to view insurance as part of doing business rather than an optional extra.

Insurance and personal financial protection

One aspect that is often overlooked is the link between business insurance and personal finances.

If you operate as a sole trader, there is no legal separation between you and the business. This means claims against the business can affect your personal assets.

Even for limited company directors, there are situations where personal liability can arise, particularly if insurance is inadequate.

Insurance is therefore not just about protecting the business, but also about protecting yourself and your family.

How much does business insurance cost

Cost is one of the biggest concerns for small business owners. The good news is that basic cover is often more affordable than expected.

The cost depends on factors such as:

  • Type of business

  • Level of cover

  • Turnover

  • Number of employees

  • Claims history

Many small businesses can obtain essential cover for a relatively modest annual cost. The key is to ensure the cover is appropriate and not excessive.

Common mistakes I see with business insurance

Over the years, I have seen several recurring issues.

These include:

  • Assuming personal insurance covers business activities

  • Choosing the cheapest policy without understanding exclusions

  • Failing to update cover as the business grows

  • Not disclosing changes in activities to insurers

Insurance is not something you set up once and forget. It should be reviewed periodically, particularly when the business changes.

Insurance and limited companies versus sole traders

While the type of insurance needed is often similar, the implications differ.

Sole traders face greater personal exposure and may benefit from broader cover. Limited companies offer some legal separation, but that does not eliminate risk.

In both cases, insurance should be viewed as part of responsible business management.

Do start ups really need insurance

Start ups often feel they cannot justify the cost of insurance. In reality, start ups are often more vulnerable than established businesses.

They typically have limited reserves, limited systems and less experience dealing with disputes. A single issue can derail progress entirely.

Starting with basic cover and expanding as the business grows is usually sensible.

Reviewing insurance as your business grows

As businesses evolve, so do risks. Taking on staff, expanding services, moving premises or increasing turnover all affect insurance needs.

Regular reviews help ensure cover remains appropriate and avoids gaps.

This is particularly important when entering new markets or offering new services.

Final thoughts

So, do you need insurance to run a small business. In some cases, yes by law. In many others, yes in practice.

Insurance is not about expecting the worst, it is about being prepared for it. The right cover allows you to focus on growing your business without constant worry about what could go wrong.

In my experience, the most successful and resilient small businesses treat insurance as part of their foundation rather than an afterthought. They understand their risks, insure sensibly and review cover as the business develops.

That approach does not eliminate uncertainty, but it does provide stability, confidence and peace of mind, which are invaluable when running a business for the long term.
