How Much Does Professional Indemnity Insurance Cost in the UK?

The cost of professional indemnity insurance in the UK depends on the type of work a business carries out, its annual turnover, the level of cover required and its previous claims history. A freelance designer may pay considerably less than an architect, accountant or engineering consultancy because the potential financial consequences of a professional error can differ between industries.

Understanding the professional indemnity insurance cost UK businesses should expect is important when planning insurance budgets. Some insurers advertise policies from approximately £69 to £81 per year for eligible low-risk businesses. However, these are lower-end starting prices rather than typical premiums for every profession.

Professional Indemnity Insurance is designed to protect businesses against certain claims arising from their professional services, including allegations of negligence, errors or omissions. It may also cover eligible legal defence costs and compensation, subject to the policy wording, exclusions and limits.

This guide explains how much professional indemnity insurance may cost, what influences the premium and how businesses can compare policies before choosing suitable protection.

1. How Much Does Professional Indemnity Insurance Cost in the UK?

There is no standard price for professional indemnity insurance. Insurers assess each application individually, which means two businesses offering similar services may receive different quotations.

For some low-risk businesses, published starting prices are relatively affordable. For example, AXA reported that 10% of its customers paid £69 or less annually for professional indemnity insurance between April and June 2026. Simply Business reported that its cheapest 10% of customers paid £80.80 or less annually for up to £1 million of cover between April and September 2026.

These figures represent the cheapest end of the market. They should not be treated as the average premium or a guaranteed quotation.

Professional firms undertaking more complex or higher-risk work may pay hundreds or thousands of pounds annually.

The following examples provide a more useful indication of costs for certain professional businesses.

The professional firm figures are based on the middle half of selected recent placements published by Apex Insurance Brokers. They are examples rather than guaranteed prices or industry-wide averages. Actual premiums may be higher or lower depending on the individual business and the insurer's assessment.

Businesses should also check whether Insurance Premium Tax (IPT), broker fees or instalment charges are included in a quoted price.

2. What Factors Affect Professional Indemnity Insurance Costs?

Insurers consider several details before calculating a professional indemnity insurance premium. Understanding these factors can help business owners understand why their quotations differ.

Type of Profession and Services Provided

The type of professional work undertaken is one of the main factors affecting insurance costs.

A business that provides general marketing advice may have a different risk profile from an engineering consultancy responsible for technical designs or an accountant handling complex financial reporting.

Insurers consider the potential financial consequences of an error, omission or negligent recommendation.

For example, an incorrect design specification could lead to expensive remedial work, while inaccurate financial advice may cause a client to suffer a substantial financial loss.

Businesses working in professions with higher potential claim values may therefore face higher premiums.

Annual Turnover and Professional Fee Income

Annual turnover or fee income can influence the cost of professional indemnity insurance.

A business generating higher professional fees may handle more projects, serve more clients or undertake larger assignments. This can increase its potential exposure to claims.

For example, a freelance consultant earning £40,000 annually may have different insurance requirements from a consultancy firm generating £500,000 in professional fees.

However, turnover alone does not determine the premium. Insurers also consider the nature of the work, the size of individual contracts and the responsibilities accepted by the business.

Level of Cover Required

The amount of insurance protection selected is another important pricing factor.

The indemnity limit represents the maximum amount an insurer will pay for covered claims, subject to the policy terms. Businesses may be able to choose limits such as £250,000, £500,000, £1 million or higher, depending on the insurer and profession.

Higher indemnity limits generally cost more because they expose the insurer to a greater potential financial commitment.

Before selecting a limit, businesses should consider their contractual requirements, professional body rules and the potential financial impact of a claim.

Choosing a lower limit simply to reduce the premium may leave a business with insufficient protection.

Previous Claims and Claims History

An insurer may ask whether the business has experienced previous claims, complaints or circumstances that could lead to a claim.

A history of professional negligence allegations may affect the premium, available cover or policy conditions.

For this reason, businesses should provide accurate information when requesting quotations. They should also maintain suitable working procedures, document professional advice and deal with client complaints appropriately.

Number of Employees and Business Structure

A sole trader providing services independently may have different insurance requirements from a company employing several professionals.

Insurers may consider the number of employees, the work they undertake, supervision arrangements and the services provided across the organisation.

Businesses should disclose relevant activities and staff responsibilities when applying for cover. This helps insurers assess the actual professional risks rather than relying on an incomplete description of the business.

Excess and Policy Conditions

The excess is the amount a business may have to contribute towards an eligible claim.

Some policies allow businesses to select different excess levels. A higher excess may reduce the premium, but it also means the business could have to pay more towards a claim.

The policy wording, exclusions and other conditions can also influence the price offered.

Businesses should compare the full terms of each quotation rather than choosing a policy based only on its annual premium.

3. How Much Does Professional Indemnity Insurance Cost for Different Professions?

Different professions face different types of professional liability exposure. As a result, insurance costs can vary considerably even when businesses have similar turnover levels.

Freelancers and Independent Consultants

Freelancers may provide services such as graphic design, copywriting, marketing, business consultancy and IT support.

Some low-risk freelancers can find relatively inexpensive policies, particularly when they have modest fee income and straightforward professional activities.

However, the cost can increase if they work on larger contracts, provide specialist advice or accept significant responsibilities for client projects.

A freelancer should check whether the policy covers all the services they actually provide.

Accountants and Financial Professionals

Accountants and financial professionals may prepare financial reports, handle business records and provide advice that influences important financial decisions.

An error or omission could potentially cause a client substantial financial loss.

Professional indemnity insurance may also be required by relevant professional bodies or regulatory arrangements. Businesses should check the requirements applicable to their membership and activities.

Architects and Engineering Consultants

Architects and engineering professionals may undertake design work, technical calculations, project planning and specialist recommendations.

An alleged error could lead to expensive remedial work, project delays or financial losses for clients.

The complexity of projects, professional responsibilities and contractual requirements can all influence the premium.

IT Consultants and Technology Businesses

IT consultants may provide software development, system implementation, technical support, data-related services and cybersecurity advice.

A mistake during implementation or an error in professional recommendations could disrupt a client's operations.

The cost of cover depends on the specific services provided, contract values, turnover and the level of responsibility accepted.

Management and Business Consultants

Management consultants may advise clients on business operations, financial planning, strategy, recruitment or organisational changes.

If a client alleges that incorrect advice caused financial loss, the consultant could face a professional liability claim.

The type of advice, client industry, project value and previous claims history can all influence the insurance premium.

4. Does a Higher Level of Cover Increase the Premium?

Generally, selecting a higher indemnity limit can increase the cost of professional indemnity insurance. However, the premium does not necessarily rise in direct proportion to the amount of cover.

For example, a policy with a £2 million limit will not necessarily cost twice as much as a policy with a £1 million limit. Insurers use their own underwriting and pricing methods to calculate premiums.

Businesses should consider the following before choosing a limit:

1. The minimum cover required by a professional body or regulator.

2. The insurance limit requested by clients.

3. The value and complexity of the contracts undertaken.

4. The potential financial consequences of an alleged professional error.

5. Whether the limit applies to each claim or in total during the policy period.

Some businesses may need higher limits because of contractual obligations, while others may require a more modest level of protection.

The important point is to select a limit that reflects the business's actual exposure rather than choosing one simply because it is cheaper.

5. Is Professional Indemnity Insurance Compulsory in the UK?

Professional indemnity insurance is not compulsory for every business in the UK. However, certain professions must maintain suitable cover because of professional body or regulatory requirements.

The Association of British Insurers identifies solicitors, accountants, architects, chartered surveyors and financial advisers among professions where professional indemnity insurance may be required by relevant professional or regulatory arrangements.

For example, RICS-regulated firms must maintain adequate and appropriate professional indemnity insurance in accordance with RICS requirements.

Even when insurance is not legally or professionally compulsory, clients may make it a condition of working with a business. Commercial contracts can specify a minimum indemnity limit that a supplier or consultant must maintain.

Businesses should check their individual requirements before purchasing a policy.

6. How Can Small Businesses Find Affordable Professional Indemnity Insurance?

Finding affordable cover does not mean selecting the cheapest available policy. Businesses should look for a balance between the premium, the protection provided and the conditions attached to the policy.

There are several practical steps that may help.

Provide Accurate Business Information

When requesting a quotation, describe the professional services provided, annual fee income and business activities accurately.

Incorrect or incomplete information can lead to unsuitable terms or problems if a claim arises.

Choose an Appropriate Indemnity Limit

Review client contracts and professional requirements before selecting a limit.

Avoid paying for an unnecessarily high limit, but do not reduce protection below the level required for the work undertaken.

Compare Different Insurers

Premiums and policy conditions can vary between insurers. Comparing suitable quotations may help identify better-value options.

However, make sure that the quotations provide comparable limits and cover.

Review the Policy Excess

Consider whether the business could comfortably afford the excess if a claim occurred.

A lower premium may not represent good value if the excess is too high for the business to manage.

Maintain Good Professional Procedures

Clear client agreements, accurate records, quality checks and employee training can help businesses manage professional risks.

These measures do not guarantee lower insurance premiums, but they can support better risk management and help prevent avoidable problems.

7. Why Should Businesses Use a Professional Indemnity Insurance Broker?

Understanding different policy wordings and insurance requirements can be difficult, particularly for businesses working in specialist or regulated professions.

A professional indemnity insurance broker can help businesses understand available cover options and compare suitable policies from insurers they have access to.

A broker may assist with:

• Understanding the professional risks associated with business activities.

• Comparing available quotations and policy terms.

• Reviewing indemnity limits and excesses.

• Identifying relevant exclusions and policy conditions.

• Understanding contractual and professional insurance requirements.

• Reviewing existing cover before renewal.

• Explaining retroactive dates and continuity of insurance.

A broker can be particularly useful when a business provides several professional services or has complex contractual responsibilities.

However, businesses should still review the policy documents carefully. The actual protection depends on the insurer's wording, exclusions, conditions and limits.

8. What Should Businesses Check Before Buying a Policy?

The premium is only one part of choosing suitable professional indemnity insurance. Businesses should understand how the policy operates and what protection it provides.

Claims-Made Policy Conditions

Professional indemnity insurance is commonly arranged on a claims-made basis. This generally means that the policy in force when a claim is first made and notified, subject to the wording, is the policy that may respond.

Businesses should understand the notification requirements and avoid allowing cover to lapse without considering the consequences.

Retroactive Date

A retroactive date determines how far back the policy may cover professional work, subject to its terms and conditions.

If a business changes insurers, it should check whether the new policy maintains an appropriate retroactive date. A later date could leave some previous work outside the scope of cover.

Policy Exclusions

Exclusions explain situations or types of loss that the insurer will not cover.

Businesses should pay particular attention to exclusions that relate to their professional activities, contractual responsibilities and specialist services.

Indemnity Limits

Check whether the policy limit applies to each individual claim or is the total available for all claims during the policy period.

This distinction can make a significant difference when several claims arise.

Run-Off Cover

Businesses that stop trading, retire or close their professional practice may still face claims relating to work completed in the past.

Run-off cover may provide protection against eligible claims made after the business has ceased trading. Its availability, duration and terms should be reviewed before existing cover ends.

9. When Should Businesses Review Their Professional Indemnity Insurance?

Professional indemnity insurance should be reviewed regularly, particularly when a business experiences significant changes.

A review may be necessary when:

• Annual turnover or professional fee income increases.

• The business begins offering new services.

• The company takes on larger or more complex contracts.

• Additional employees or professional consultants are recruited.

• Client contracts introduce new insurance requirements.

• The business expands into new markets.

• The existing policy premium or terms change at renewal.

Businesses should not wait until the annual renewal date if their professional responsibilities change significantly during the policy period.

Regular reviews help ensure that the insurance arrangements remain relevant to the services being provided.

Conclusion

The cost of professional indemnity insurance in the UK varies according to the profession, annual fee income, indemnity limit, business activities and claims history. Some low-risk freelancers may find policies starting at approximately £69 to £81 annually, while established professional firms can pay hundreds or thousands of pounds for suitable cover.

There is no single premium that applies to every business. The most useful approach is to compare quotations based on similar cover limits and policy conditions while considering the risks associated with the work being undertaken.

A professional indemnity insurance broker can help businesses understand their options, review policy terms and identify suitable cover arrangements. By combining appropriate insurance with clear contracts, accurate records and effective risk management, businesses can make more informed decisions about protecting their professional acti
