Working With Your FDWhat Professional Indemnity Insurance Do You Carry?
Understanding professional indemnity insurance for fractional Finance Directors — what it covers, what to require, and why it matters when engaging a fractional FD for your UK business.

Professional indemnity (PI) insurance is a fundamental requirement for any fractional Finance Director operating as a self-employed consultant or through a personal services company. Asking about professional indemnity insurance before engaging a fractional FD is sensible due diligence — a responsible practitioner will carry adequate cover as a matter of professional obligation, and any reluctance to confirm the position should be treated as a serious warning sign.
All Finance Directors on the FractionalFD platform are required to hold current professional indemnity insurance as a condition of participation in the network. We verify cover at the point of onboarding and require annual renewal confirmation. When we introduce an FD to your business, we can confirm that their PI insurance is in place and provide details of the policy limits on request.
What Professional Indemnity Insurance Covers
Professional indemnity insurance protects a professional adviser against claims arising from errors, omissions, or negligence in the provision of professional services. In the context of a fractional Finance Director, this means claims arising from incorrect financial analysis, faulty financial modelling, errors in forecasts that were relied upon in making significant business decisions, or negligent advice on matters such as tax planning, fundraising strategy, or financial reporting.
If a business suffers a financial loss that it attributes to the negligence or errors of its fractional FD, professional indemnity insurance provides the financial resource to investigate the claim, defend against it where appropriate, and pay any damages and legal costs that result from an upheld claim. Without PI insurance, a successful claim against an individual FD may result in an unsatisfied judgment if the individual lacks the personal financial resources to meet the award.
What PI Insurance Does Not Cover
Understanding the limitations of professional indemnity insurance is as important as understanding what it covers. PI insurance does not protect against fraud or deliberate wrongdoing — if an FD knowingly provides false information or acts dishonestly, no insurance policy will respond to claims arising from that conduct. It also does not typically cover claims arising from the FD acting outside the scope of their agreed engagement, or from decisions made by the business owner that the FD advised against.
PI insurance also does not cover losses arising from changes in the business environment, market conditions, or regulatory requirements that affect the value of financial advice previously given. Financial advice is necessarily forward-looking and probabilistic — a forecast that proves wrong because of an economic event that was unforeseeable does not create a valid professional negligence claim simply because the outcome was different from the projection.
What Level of Cover Is Adequate?
The appropriate level of professional indemnity insurance cover depends on the scale and nature of the work being performed. A fractional FD advising a business turning over £500,000 carries a different risk profile to one advising a business turning over £10m with a complex balance sheet and multiple lenders.
Minimum Cover Standards
For fractional Finance Directors working with UK SMEs, professional indemnity insurance of at least £500,000 per claim and in aggregate is generally considered a minimum acceptable level. For FDs working with businesses of significant size, involved in complex fundraising transactions, or advising on areas of significant financial risk, cover of £1m or more per claim is more appropriate.
When reviewing a fractional FD's PI insurance, ask specifically about:
- The limit per individual claim (not just the aggregate annual limit)
- The insurer's financial strength and UK authorisation status (check the FCA register)
- Whether the policy is written on a "claims made" or "claims occurring" basis — claims made policies cover claims notified during the policy period, regardless of when the event occurred; understanding this distinction matters if the engagement ends
- Any specific exclusions that might be relevant to the work being performed
- Whether the policy covers the specific activities the FD will be performing — some policies exclude certain types of work such as tax advice or regulatory compliance
Other Insurance Considerations
Professional indemnity insurance is the primary relevant coverage, but a thorough due diligence process should also consider whether the fractional FD holds public liability insurance (relevant if they attend your premises) and cyber liability insurance (relevant if they will handle sensitive financial data through their own systems).
Cyber Liability Insurance
A fractional Finance Director handles highly sensitive data: financial records, payroll information, bank account details, personal data of customers and suppliers. If that data is compromised through a breach of the FD's own systems — a phishing attack, for example — cyber liability insurance provides the resource to manage the breach notification, investigation, and any resulting regulatory or civil liability. Increasingly, businesses that take their data security obligations seriously under UK GDPR will expect their advisers to carry appropriate cyber cover.
The Role of Professional Body Membership
Professional body membership — particularly for qualified accountants holding ACA (ICAEW), ACCA, or CIMA designations — provides an additional layer of reassurance beyond insurance. These bodies impose continuing professional development requirements, uphold codes of ethics, and provide disciplinary mechanisms for members who breach professional standards. A fractional FD who is a current member in good standing of one of these bodies has made a commitment to professional conduct that is backed by a regulatory framework.
The ICAEW's practice assurance scheme, for example, requires member firms to demonstrate that they have appropriate quality control systems, client money handling procedures, and professional indemnity insurance in place. Members who practise on an individual basis are subject to equivalent requirements. This institutional accountability is separate from and complementary to the protection provided by PI insurance itself.
"We asked to see the PI insurance certificate before we signed the engagement letter. Our FD provided it immediately and without any hesitation. That straightforwardness was itself reassuring — it told us we were dealing with someone who takes their professional responsibilities seriously."
Contractual Protections Beyond Insurance
Professional indemnity insurance is one layer of protection, but a well-drafted engagement letter or services agreement provides additional contractual protections that can be equally important in practice. A professional engagement letter should clearly define the scope of services, the specific deliverables and their timing, the basis on which advice is provided and its limitations, and the process for resolving disputes.
Clarity on scope is particularly important: if the engagement letter clearly defines what the FD is and is not responsible for, claims arising from activities outside that defined scope are significantly harder to bring successfully. A fractional FD who proposes a clear, professionally drafted engagement letter is demonstrating the same professional discipline that good PI cover reflects.
