The Professional Services Practice at Aon is a global team of dedicated practitioners who address the unique insurance, risk and human capital needs of professional service firms.

Our industry knowledge allows us to act as trusted advisors, helping our clients optimize their risk management and human capital decisions with impactful insights, data and tools.
What We Do
Insurance Coverage for Professional Service Firms
For law, accounting, and consulting firms, managing and insuring their professional liability exposure is crucial to protecting their reputation and revenue. We help our clients secure the coverage they need across a wide range of exposures, including:
-
Professional Liability
Professional liability is a fundamental risk for professional service firms with the potential for severe financial impact and reputational damage.
We tailor coverage and create insurance structures around a firm’s specific needs and across all types of professional liability risk.
Professional liability coverage is also known as professional indemnity insurance or errors and omissions liability insurance. The terms are often used interchangeably, depending on the context.
-
Cyber Risk
In evaluating cyber risk insurance, it is important to understand the risks and exposures an insurance policy may or may not address.
Coordinating cyber risk and professional liability coverage is a serious challenge for professional service firms. Since the terms and conditions of each cyber risk insurance product vary greatly, we examine and modify each offering to present a recommended solution that is tailored to our clients' unique needs.
-
Management Liability
When an executive committee or individual assumes ultimate responsibility for a firm’s business operations, these decision-makers are exposed to many of the same liabilities faced by directors and officers of public corporations.
We design Management Liability programs specifically for professional partnerships to help firms protect their partners and managers.
-
Employment Practices Liability
Employment practices liability (EPL) insurance addresses specialized liability risks arising from actual or alleged wrongdoing at work.
Several factors have contributed to an increase in EPL exposure for professional services firms, including:
- Increased media attention on workplace harassment claims
- New state, local, and international laws regarding gender pay disparity
- Aging of the workforce
- Larger number of law firms specializing in employment-related claims
- Growing challenges to arbitration agreements
- Significant changes in the law including the 1991 Civil Rights Act, the Americans with Disabilities Act, Age Discrimination in Employment Act, and Older Workers Benefit Protection Act
- M&A activity resulting in more employment-related claims
We help professional service firms address their EPL exposures by providing customized coverage solutions.
-
Property and Casualty
Our approach to property and casualty coverages include the planning, execution, and stewardship of the following coverages:
- Property insurance, including Business Interruption
- Workers’ Compensation / Employers’ Liability
- General Liability, Automobile Liability and Umbrella Liability
- Global Programs (including local placements)
- Crime, Fiduciary and Kidnap, Ransom and Extortion
- Group Personal Umbrella
- Travel Accident
We have developed proprietary property insurance wording designed specifically for professional service firms which provides exceptionally broad protection and addresses their special coverage needs.
Risk Management and Advisory Services
Law, accounting and consulting firms also face other legal and operational exposures that require careful risk management and financing treatment. We can help with:
-
Risk Financing, Actuarial Risk Analysis and Captives
We help organizations optimize their Total Cost of Risk and answer the following questions:
- How much risk can I retain?
- How much risk should I retain?
- How should I finance that risk?
- Is a captive insurance company suitable for my risk exposures?
- How can my existing captive retain more risk or play a more central part in my risk financing strategy?
We undertake a structured evaluation of an organization’s risk tolerance/appetite and build an understanding of its ability to retain risk, which allows us to develop optimum risk financing programs.
Our actuaries focus on professional service firms and understand their risk modeling and loss forecasting needs. They provide risk pricing and loss reserving in support of captive financing.
-
Loss Prevention
Identifying and avoiding or minimizing liability and professional responsibility risks is crucial for law firms.
Our dedicated team of law firm loss prevention specialists includes former law firm partners with years of experience in loss prevention, legal ethics, and professional liability law. They carefully tailor their services to firm needs and interests. These value-added services are only for clients for whom we broker lawyers’ professional liability insurance.
-
Risk Management Information
We provide qualitative advice, tools and deliverables to help accounting and consulting firm clients understand and quantify current and emerging risks, enabling them to make better risk mitigation, retention and transfer decisions.
Human Capital Solutions
Our team provides a wide array of human capital solutions focused on the unique needs of professional service firms, including:
- Health and benefits
- Partner and executive benefits
- Retirement and investment services
- People analytics
- Reward solutions
