Do Accountants Really Need Professional Indemnity Insurance?

A fire in your accountancy office destroys everything. Your landlord is responsible for covering the damage to the building; you claim on your business contents insurance for the loss of your computers, printers, office furniture, phones and other business property. Declaring business use to a personal car insurance provider is critical for covering driving between multiple work locations or to see clients. If you use your car in these ways but don't declare business use, then your regular car insurance (e.g., social, domestic and pleasure driving, commuting use) could be deemed invalid and you'd essentially be driving uninsured.

PII minimum approved policy wording

To illustrate the variability in costs for accountant PII, we recently ran some sample quotes through a large provider of PII insurance in the UK. We found that prices can vary by 7X or more for the same accountant profile from one insurance provider to another. And that premiums go up with coverage. Because the ICAEW baseline minimum for even the smallest firms is now £250,000, the previous £100,000 coverage tier is no longer compliant for chartered accountants. For a 2026 small practice with up to £100,000 in fee income, fresh sample quotes for the mandatory £250,000 PII limit now range from approximately £210 on the low end to £1,450 on the high end, depending on the firm's specific risk profile and claim history.

To learn more about costs of other types of business insurance for an accountancy business, read our article about typical business insurance costs in the UK. Ultimately, the cost of insurance for an accountancy business depends on the risks involved. Quotes for your accountancy business might be significantly higher or lower, depending on how insurers calculate the risks involved. They each have proprietary risk models that use the details of an application to assess risk, so quotes can be highly variable from situation to situation. A self-employed accountant will generally need the same types of insurance as a larger accountancy practice: PII to protect against client claims of negligent advice or service Public liability to protect against third party personal injury or property damage claims Employers' liability to protect against work-related injury or illness of any you employ Contents and equipment cover to protect your business equipment and office furniture from a fire, flood, theft, etc. You have an at-fault accident while driving your personal car to visit a client to go over their year end accounts. Luckily, you had previously declared and paid for business use on your car insurance policy so your insurance covers the damage to your vehicle and another vehicle involved in the crash. Roughly speaking, legal expenses policies cover many situations that are not covered by other types of liability insurance. Business legal expenses insurance (LEI) gives you access to an expert legal team and pays your legal defence costs in certain situations up to the policy limit for situations such as: Legal Expenses Insurance Example: You have a dispute with a client that ends in them not paying you for your work. Your LEI insurance covers the cost of legal assistance to pursue a claim against the client. Cyber insurance can be an important aspect of business insurance coverage for an accountant or any other profession that holds sensitive client information such as names, addresses, banking information and private financial details. Cyber insurance covers losses related to hacking, data breaches, viruses and other cyber crimes, paying both direct costs incurred by your business and also claims from third parties that were harmed by an attack on your business. Cyber Insurance Example: You open an email attachment with a virus that allows hackers to gain access to company files and sensitive client information.

Annual Fee Income Band (GBP)	Minimum Limit per Claim	Minimum Aggregate Limit	Excess/Deductible Guideline
Up to 100,000	100,000	1,500,000	1% of income or 2,500
100,001 - 500,000	500,000	3,000,000	1.5% of income
500,001 - 2,000,000	1,000,000	5,000,000	0.75% of income
Over 2,000,000	2,000,000	10,000,000	Negotiated, based on risk

Cyber insurance pays for experts to deal with the situation, including paying a ransom, credit score monitoring for customers, etc. An age-old question—how much insurance do I need? Professional indemnity insurance for accountants is typically offered with a limit of insurance between £50,000 and £5 million, but large firms can source higher limits with excess cover. The recommended amount of professional indemnity for an accountant is typically linked to the level of its fee income. Calculating the amount of insurance an accountant needs can certainly be a complicated answer and a broker or insurer can help you figure it out. Some professional bodies also give a good amount of guidance. For a full analysis see our article How Much PI Insurance Does an Accountant Need? Chartered accountants are required to hold PII as part of their membership, with limits of insurance dependent on the work they carry out and their fees.

What to look for with PI cover

For smaller practices with a gross fee income of less than £800,000, the required limit is calculated as two and a half times the firm's gross fee income, subject to an absolute minimum of £250,000. All references to the previous £100,000 minimum or £600,000 income threshold are now obsolete. You'll need professional indemnity insurance and to follow the guidelines regarding minimum insurance requirements. For example, ACCA declares that cover must also include fidelity guarantee insurance (FGI) where a practitioner is in partnership, or has fellow directors in an incorporated firm, or employs full-time or part-time staff. (For an accountant, FGI would protect against the losses as a result of a dishonest or fraudulent act by an employee.) And PII is compulsory for all ICAEW members with a practising certificate who are in public practice—and there are minimum requirements for this coverage.

When a Tax Error Becomes a Claim

Here is a list of the main professional bodies in the UK, with links to their professional liability insurance requirements so you can learn more: The cost of professional indemnity insurance (PII) for an accountant starts from a range of £210 a year to £1,450 a year or more. Prices depend on lots of different factors, with your total annual fee volume and the size of your largest fee (e.g., from one client) being primary factors. As discussed above, these fee figures affect the limit of insurance an accountant is required to buy—and higher limits of insurance translate into more risk for an insurer, and therefore a higher premium. The type of accountancy work performed also has a bearing on premiums, as well as the number of insurers willing to insure an accountant. For example, for our sample test case we found that Hiscox quoted for an accountant involved in audit work, general accountancy, payroll and personal tax consultancy—but wouldn't offer a quote for an accountant performing secretarial work or share registrations.

Policy Documents

Accountants involved in tax planning schemes will find it harder to get insurance, too. You'll also find that premiums can be vastly different from one insurer to the next, which is not surprising because of the specialist risks involved. Insurers with less appetite for a certain risk profile (e.g., certain types of accountancy work) either won't offer a policy or may charge a significant amount more than alternatives in the marketplace. For this reason, it's very important to compare the market when getting PII quotes. A broker can help in this regard, if they work with multiple underwriters. Let's have a look at the minimum PII requirements as stipulated by the Association of Chartered Certified Accountants (ACCA) for the UK, as well as ICAEW requirements. According to current ACCA regulations, the minimum limit of indemnity on PII for accountants in respect of each and every claim is at least £100,000. However, the vast majority of firms are required to hold a higher limit based on their total annual fee income. 2026 Calculation Examples Here are updated examples illustrating how these 2026 thresholds apply to various firm sizes: £20,000 in total fees: The PII minimum limit is the absolute baseline of £100,000.

Other considerations when deciding how much professional indemnity insurance is enough

While other providers like Direct Line for Business previously offered direct cover, the official list for the period 1st September 2025 to 31st August 2026 indicates that almost all other insurers must be approached through a qualified broker. The 2025/2026 list of participating insurers has been refreshed to reflect the current market participants authorized by the ICAEW. Professional indemnity insurance is a requirement for accountants who are members of the main professional bodies in the UK. A fire in your accountancy office destroys everything. Your landlord is responsible for covering the damage to the building; you claim on your business contents insurance for the loss of your computers, printers, office furniture, phones and other business property. £2,000,000 in total fees: The PII minimum limit remains £1,500,000 (though most firms of this size will opt for £2m–£5m for commercial security). Under the ICAEW Professional Indemnity Insurance Regulations (fully active for the 2026 reporting year), the minimum limit of indemnity for most firms is now £2 million for any one claim and in the aggregate. For smaller practices with a gross fee income of less than £800,000, the required limit is calculated as two and a half times the firm's gross fee income, subject to an absolute minimum of £250,000.

• Financial penalty for non-compliance can be up to £5,000
• Suspension of membership is a potential consequence
• ACCA's Professional Standards Department monitors compliance
• Members must notify ACCA of any material change in cover
• Breach of requirement is considered misconduct

(For an accountant, FGI would protect against the losses as a result of a dishonest or fraudulent act by an employee.)
