This is not legal advice

This article is for general information only. It is not legal, financial, or tax advice. Consult a qualified professional before making decisions for your business.

Every insurance website lists a dozen products. Very few of them tell you which ones actually apply to your situation. If you are starting a business in the UK and trying to work out what cover you need, the answer depends on three things: whether you have employees, what type of business you run, and whether your clients or contracts require specific cover.

This guide works through those questions in order. By the end, you should have a clear picture of which insurance types are relevant to your business - and which ones you can safely leave for later.

This is not insurance advice

This article explains the UK regulatory framework and helps you identify which cover is likely relevant to your business. It is not a substitute for advice from a regulated UK insurance broker, who can confirm the specific cover your business needs.

The Only Business Insurance That Is Legally Required in the UK

Most sole traders operating without employees have no legal requirement to hold any business insurance at all. That surprises a lot of new founders, but it is important to be accurate about this.

The one exception is employers liability insurance (ELI). Under the Employers' Liability (Compulsory Insurance) Act 1969 and the Employers' Liability (Compulsory Insurance) Regulations 1998 (SI 1998/2573), any business that employs staff must hold ELI with a minimum cover level of £5 million - although in practice most insurers provide at least £10 million as standard. This applies the moment you take on an employee - full-time, part-time, or in most cases temporary.

ELI covers claims from employees who are injured or become ill as a result of their work. Without it, you face significant fines from the Health and Safety Executive (HSE). There are narrow exemptions - for example, if all of your employees are close family members (as defined by the HSE) and the business is not incorporated as a limited company or LLP - but for most businesses with staff, ELI is non-negotiable.

ELI is not optional once you hire

You must have employers liability insurance in place from the day you take on your first member of staff. Failing to hold it is a criminal offence and carries a fine of up to £2,500 for every day the business is uninsured; a separate fine of up to £1,000 applies for failing to display the certificate or produce it to HSE inspectors on request. Do not delay arranging this cover if you are about to hire.

The Insurance Most Small Businesses Need Regardless of Legal Requirement

Legal requirement is only part of the picture. Many UK small businesses need certain types of insurance not because the law says so, but because their clients or contracts require it.

Public liability insurance (PLI) is the most common example. PLI covers claims from third parties - typically clients or members of the public - who suffer injury or property damage as a result of your business activities. It is not a legal requirement for most businesses, but it is contractually required by a wide range of clients, public sector contracts, and industry bodies.

If you work on client premises, attend events, or deliver any kind of physical service, you will almost certainly be asked to show proof of PLI before a contract is signed. Many sole traders discover this at the point of winning their first significant client.

How to Work Out Which Insurance Applies to Your Business Type

The right starting point is not a product list - it is a set of questions about how your business operates. Work through these before you approach any broker or comparison site.

  • Do you sell a physical product, or do you deliver a service?

  • Do you have employees, or are you operating alone?

  • Do you work on client premises, or remotely from your own location?

  • Do your clients or contracts specify required insurance?

  • Do you rely on specialist equipment or business property that would be costly to replace?

  • Do you give professional advice or design work that could be acted upon?

Your answers to these questions map directly onto the insurance types that are relevant to your situation. The sections below work through each scenario in turn.

Service Businesses: The Insurance You Almost Certainly Need

Most early-stage UK businesses are service businesses - consultants, designers, marketers, tradespeople, coaches, IT contractors, and similar. The insurance picture for this group is relatively focused.

Public Liability Insurance

If you interact physically with clients, visit client premises, or work in public spaces, PLI is effectively essential. It covers bodily injury to others and damage to third-party property caused by your business activities. Cover levels typically start at £1 million to £2 million for lower-risk businesses, but £5 million or more is common in higher-risk sectors or where government or local authority contracts are involved.

Professional Indemnity Insurance

Professional indemnity insurance (PI) covers claims arising from mistakes, errors, or omissions in your professional work. If a client suffers a financial loss because of advice or work you provided, PI covers the legal costs and any resulting claim against you.

PI is particularly relevant for consultants, advisers, designers, IT professionals, accountants, and anyone whose work is relied upon by clients to make decisions or complete projects. Some regulated professions are legally or regulatorily required to hold PI cover — for example, financial advisers must hold PI under FCA rules (MIPRU 3.2), solicitors under SRA requirements, and architects under ARB rules.

Check your contracts first

Before buying cover, review your client contracts. Many specify a minimum cover level for both PLI and PI. Buy to meet your actual contractual requirements, not just a default level.

Product Businesses: The Additional Cover That Applies

If your business sells, manufactures, or imports physical products, you face a specific category of risk that service businesses do not - claims arising from products that cause injury or damage after they leave your hands.

Product liability insurance covers this exposure. It sits alongside PLI and covers claims where a product you sold or made causes bodily injury or property damage to a third party. Many insurers bundle product liability with public liability in a combined policy, which is worth checking when you compare quotes.

If you are selling on platforms like Amazon - where FBA sellers on the UK marketplace must hold public and product liability cover of at least £400,000 per occurrence - or supplying products to UK retailers, product liability cover is frequently required as a condition of the commercial relationship. Check the terms of any sales channel or wholesale agreement before trading.

Importing products adds complexity

If you import products from outside the UK and sell them here, you may be treated as the manufacturer for the purposes of UK product liability law - even if you did not make the product. This increases your exposure and makes product liability cover more important, not less.

If You Have Employees: What Becomes Mandatory the Moment You Hire

Hiring your first employee changes your insurance position immediately. Employers liability insurance becomes a legal requirement on day one - this has already been covered above, but it bears repeating because the timing matters. You cannot hire first and sort the insurance later.

Beyond ELI, taking on staff typically makes other cover more relevant even if not strictly mandatory.

  • Business interruption insurance becomes more meaningful when you have staff costs to cover even if income stops unexpectedly.

  • Key person insurance - a business-owned policy that pays out to the company on the death or, in many cases, the serious illness of a critical employee or director - becomes relevant once the business's trading income depends significantly on specific individuals.

  • If staff drive for work, your motor insurance arrangements need to reflect business use.

None of these are legally required in the way ELI is, but each addresses a real financial risk that grows as the business does.

Insurance You Can Probably Wait On Until You Grow

Not everything on an insurer's product page is relevant to a business at launch. A common mistake is buying cover to feel comprehensive rather than because there is a genuine risk to manage.

The following types of cover are legitimate and useful in the right circumstances - but are unlikely to be a priority for a founder in the first year of trading.

  • Cyber insurance - worth considering once you hold meaningful customer data or process payments, but less relevant if you are operating at very small scale with minimal data exposure.

  • Business interruption insurance - most useful when your business has significant fixed costs. At very early stage with low overheads, the risk profile may not justify the premium.

  • Directors and officers insurance (D&O) - covers directors for claims related to decisions they make. Relevant once you have a formal board structure or significant outside investors, not typically a day-one purchase for a sole founder.

  • Legal expenses insurance - covers the cost of disputes with suppliers, clients, or employment tribunals. A practical addition once you have contracts and relationships to protect, but not essential at pre-revenue stage.

Do not buy cover for risks you do not yet have

Insurance is a cost. At early stage, the right discipline is to cover the risks that are real and present - legal requirements, contractual obligations, and the exposures most likely to materialise. You can build out your cover as your business grows and your risk profile changes.

How to Buy Business Insurance Without Overpaying

Once you know which types of cover you need, the buying process is straightforward - but a few practical steps will help you get better value.

Buying Business Insurance: A Practical Approach

Define your cover requirements first

Use the questions and sections above to identify which insurance types apply to your situation before you approach any insurer or broker. Know whether you need PLI, PI, ELI, product liability, or a combination. Know the minimum cover levels specified in your contracts.

Use a comparison platform for initial pricing

UK comparison platforms allow you to benchmark pricing across multiple insurers for standard cover types. This is a useful starting point, particularly for PLI and combined policies. Do not use it as your only step - compare like-for-like cover, not just headline premiums.

Speak to a regulated broker for specialist needs

If your business operates in a regulated sector, works in specialist industries such as construction or healthcare, or requires higher cover levels, use a regulated UK insurance broker. A broker can access policies that are not on comparison platforms and advise on the right structure for your risk profile.

Review annually as your business changes

Your insurance needs will change as you hire, grow, or change how you operate. Set a calendar reminder to review your cover at each renewal. Do not let policies auto-renew without checking that the cover still matches your current situation.

BGE does not recommend specific insurers by name. The right insurer for your business depends on your sector, your cover requirements, and your risk profile — a regulated broker is the most reliable route to getting this right.

Frequently asked questions

Do I need business insurance?

Many founders starting a business are uncertain about what insurance they are legally required to hold and what they should hold out of commercial prudence. The answer depends on your business structure, the nature of your work, whether you have employees, and the requirements of your clients and any contracts you sign.
Some forms of business insurance are legally required: employer's liability insurance is compulsory for most businesses with employees, and certain regulated professions must hold specific cover by law or by their professional body. Beyond these requirements, insurance such as public liability and professional indemnity is effectively mandatory in practice for businesses that work with the public, visit client premises, or provide advice and professional services — even where the law does not require it.
The right combination of insurance depends on what you do, how you do it, and who you work with. A home-based sole trader with no employees and no client-facing work has very different needs from a limited company with staff in a regulated sector. Our guide to business insurance for UK founders helps you identify which policies are relevant and how to think about the cover you need.

How do I choose business insurance?

Choosing the right business insurance is not simply a matter of finding the cheapest policy that covers the legally required minimum. The insurance a business actually needs depends on legal obligations, contractual requirements from clients and lenders, the specific risks associated with the nature of the work, and a realistic assessment of what could go wrong and what the financial consequences would be.
The starting point is identifying which insurances are legally required — employer's liability if you have employees, and profession-specific cover if your sector mandates it. From there, the key considerations are the types of claim your business is realistically exposed to, what your clients require as a condition of engagement, and what your business could afford to absorb without insurance versus what would be financially catastrophic. Comparing policies on the scope of cover, not just the premium, is essential.
Many founders use a business insurance broker to navigate the options, as brokers can access a wider range of products and tailor recommendations to a specific business profile. Reviewing insurance annually — particularly as the business grows, adds employees, or enters new markets — ensures cover remains appropriate. Our guide to choosing business insurance covers the main policy types and how to assess what your UK business needs.

What is employer's liability insurance?

The moment a business takes on its first employee in the UK, a specific legal insurance obligation is triggered. Many founders are unaware of this requirement until they hire someone, and some remain unaware of it entirely until they face a compliance issue. Understanding what employer's liability insurance is and when it becomes compulsory is essential knowledge for any founder planning to grow their team.
Employer's liability insurance covers a business against claims from employees who suffer injury, illness, or death as a result of their work. It is a legal requirement in the UK for almost all businesses that have employees, including part-time and temporary workers. The law requires businesses to hold a minimum level of cover and to display the certificate of insurance. Failing to hold the required cover can result in significant daily fines from the Health and Safety Executive.
There are limited exemptions to the requirement — including businesses with no employees other than close family members — but these are narrow, and any doubt about whether the requirement applies should be resolved before taking on staff. Our guide to employer's liability insurance explains who is required to hold it, what it covers, and how to ensure your business is compliant from the first day of employment.

What is public liability insurance?

Public liability insurance is one of the most commonly held forms of business insurance in the UK, and one that many clients, venues, and event organisers require before they will engage with a supplier. Despite its prevalence, many founders take out a policy without a clear understanding of what it actually covers, or whether the level of cover chosen is appropriate for the nature of their work.
Public liability insurance covers a business against claims made by third parties — typically customers, members of the public, or visitors to a business premises — for injury or property damage caused by the business or its employees. If a customer slips on a wet floor in your office, or your work accidentally damages a client's property, public liability insurance covers the legal costs and any compensation awarded. It does not cover claims from your own employees — that falls under employer's liability insurance.
Public liability insurance is not legally required for most businesses, but it is effectively mandatory in practice for anyone working with the public, visiting client premises, or operating in a regulated sector. Many contracts and venue agreements specify a minimum level of cover. Our guide to business insurance for UK founders covers what level of cover is appropriate for different types of work.

What is professional indemnity insurance?

Businesses that provide advice, expertise, or professional services face a specific risk not covered by general liability policies — the risk that a client suffers a financial loss as a result of the work provided. Professional indemnity insurance is designed to address this, and understanding what it covers and who needs it is relevant for any founder working in a professional or knowledge-based capacity.
Professional indemnity insurance — sometimes called PI insurance — covers a business against claims from clients who allege that the work, advice, or professional service provided was negligent, incorrect, or fell short of the standard expected. It covers the legal costs of defending such claims and any compensation awarded. It is particularly relevant for consultants, accountants, designers, engineers, IT professionals, and anyone else whose work or advice directly affects a client's financial or business outcomes.
Professional indemnity insurance is a legal requirement for certain regulated professions in the UK, including solicitors, financial advisers, and architects. For other professions it is not mandatory but is frequently required by clients as a condition of engagement. Our guide to professional indemnity insurance covers what level of cover is appropriate, how to choose a policy, and when it is effectively required even if not legally so.
