Professional Indemnity Insurance Cost 2025/26

Professional indemnity insurance protects professionals against claims from clients who allege that advice, designs or services caused them a financial loss. It is essential for any professional who gives advice, designs products or provides a service where an error could cost a client money. This includes accountants, architects, solicitors, IT consultants, surveyors, engineers, financial advisers, HR consultants and many other professions. Many professional body memberships require it.

Coverage requirements depend on contract size and professional body rules. For freelance consultants working on smaller projects, £100k-500k may suffice. Most professional bodies recommend a minimum of £1M. Architects must carry minimum PI cover equivalent to the contract value of projects under design. Solicitors regulated by the SRA must hold minimum £3M cover. Financial advisers are regulated by the FCA, which sets minimum indemnity limits. Always check your professional body's specific requirements.

Yes — professional indemnity insurance premiums are a deductible business expense for UK self-employed individuals and limited companies. They reduce your taxable profit in the year the premium is paid. For limited companies, premiums are also deductible from corporation tax. Keep records of annual renewal invoices as evidence for HMRC. PI insurance taken out for future periods (prepaid) should be apportioned across the accounting periods to which they relate.
