INSURANCE GUIDE
Accountants and Bookkeepers Insurance UK
Professional indemnity, public liability and cyber cover for UK accountants, bookkeepers and tax advisers.
TL;DR
- Professional indemnity insurance is the primary cover for accountants - it covers negligence claims from clients who suffer financial loss due to errors in your work.
- ICAEW, ACCA, AAT and other professional bodies require PI cover as a condition of membership.
- Cyber insurance covers data breach costs - important for firms holding sensitive client financial data.
- Run-off cover is needed after you stop practising to cover claims made after retirement or business closure.
Professional Indemnity Insurance for Accountants
Professional indemnity (PI) insurance covers the legal costs and compensation if a client suffers financial loss and claims it was caused by an error, omission, or negligent act in your work. For accountants and bookkeepers, this includes: errors in tax returns leading to HMRC penalties; incorrect payroll calculations; missed filing deadlines that result in fines; incorrect advice on VAT treatment; and bookkeeping errors that cause a client's accounts to misrepresent their financial position.
PI insurance covers defence costs regardless of whether the claim is ultimately upheld. Many claims against accountants are unfounded but still result in significant legal expenditure; the insurance covers this even when you are not at fault.
Professional Body Requirements
The major UK accounting professional bodies require members in practice to hold minimum levels of PI cover as a condition of holding a practising certificate. The Institute of Chartered Accountants in England and Wales (ICAEW) and the Association of Chartered Certified Accountants (ACCA) both mandate PI cover. The Association of Accounting Technicians (AAT) requires members in practice to hold appropriate PI cover. Minimum limits and conditions vary by body; check your professional body's current requirements as these are updated periodically.
Claims-Made vs Occurrence Policies
PI policies for accountants are almost universally written on a claims-made basis: the policy in force when the claim is made covers it, not the policy in force when the work was done. This means you must maintain continuous cover and, critically, obtain run-off cover when you cease practice. Run-off cover extends the policy's claims-made window for a defined period after you stop working, protecting against claims made after retirement or business closure for work done while you were practising.
Cyber Insurance for Accountants
Accountants and bookkeepers hold highly sensitive client data - bank details, payroll records, tax returns, and trading information. A data breach or ransomware attack can trigger obligations under the UK GDPR, including notification to the Information Commissioner's Office (ICO) and affected clients. Cyber insurance covers the cost of incident response, ICO notification support, and any regulatory fines where insurable. It also covers business interruption resulting from a cyber attack.
Public Liability for Accountants
Public liability covers third-party injury or property damage during the course of business. For office-based accountants seeing clients in person, this covers a client injuring themselves in your offices. For those working from home or visiting clients, it covers incidents at client premises. PI and public liability are distinct covers; holding one does not substitute for the other.

Frequently Asked Questions
Is professional indemnity insurance compulsory for accountants?
It is not a statutory legal requirement in the same way employers liability is. However, the major professional bodies - ICAEW, ACCA, AAT, CIMA - require members in practice to hold PI cover as a condition of their practising certificate. Working without PI cover while holding a practising certificate risks disciplinary action by the professional body.
How much PI cover do accountants need?
Minimum limits are set by your professional body and vary by firm size, turnover, and nature of work. Many sole practitioner accountants hold £100,000 to £500,000 of cover. Firms advising on corporate transactions or larger clients may require £1m or more. Your professional body's guidance and your own assessment of client exposure should determine the appropriate limit.
What is run-off cover for accountants?
Run-off cover extends your PI policy's claims window after you cease practice. Because PI policies are claims-made, a claim made after you retire for work done while you were practising would not be covered by your former insurer unless you purchased run-off cover. Many professional bodies require a minimum run-off period as a condition of surrendering a practising certificate.
