Is PI insurance mandatory in the UK?

Reviewed by Apex Insurance Brokers (FCA FRN 724952) · Published 14 July 2026

The direct answer: it depends on your profession. Some UK professions are legally required to hold PI cover; others aren't but practically need it because clients require it. This page sets out the mandatory / voluntary position by sector.

In short: Only if your regulator requires it, or a contract you sign does. Solicitors, ICAEW and ACCA accountants in public practice, RICS-regulated firms, architects, self-employed barristers, and FCA-authorised insurance and mortgage intermediaries and personal investment firms must hold PI under their regulators’ rules. Most other consultants and freelancers face no such rule, but clients often make PI a contract term, and public buyers can require it from the contract start. The cover the law requires of most employers is employers’ liability: at least £5 million from an authorised insurer. Any PI you hold responds subject to the policy terms.

Professions where PI is legally mandatory

Solicitors (SRA-regulated). Yes — SRA-authorised firms must hold qualifying insurance with a participating insurer on the SRA Minimum Terms: at least £2m per claim, or £3m for LLPs and limited companies.
Architects (ARB-regulated). Yes — Standard 4.7 of the Architects Code (in force from 1 September 2025) requires adequate and appropriate PII; ARB guidance expects at least £250,000 each and every claim.
Barristers (BSB-regulated). Yes for self-employed barristers, who must be members of the Bar Mutual Indemnity Fund.
Insurance and mortgage intermediaries (FCA-authorised). Yes under MIPRU 3.
IFAs (personal investment firms). Yes under IPRU-INV 13.
Accountants ICAEW / ACCA. Yes for firms in public practice — the ICAEW PII Regulations (from 1 September 2024) and ACCA’s Global Practising Regulations (GPR 9).
Surveyors RICS. Yes for RICS-regulated firms — RICS Rules of Conduct, Appendix A, and the RICS PII requirements (version 11, from 1 July 2025).
Insolvency practitioners. Yes plus statutory bond requirement.

Professions where PI is not legally required but practically essential

IT consultants and management consultants. No statutory requirement but client contracts commonly require it.
Marketing and PR consultants. No statutory requirement; contract-driven.
HR and payroll consultants. No statutory requirement; contract-driven.
Life coaches, executive coaches. No statutory requirement; client-driven.
Freelancers across most professional sectors.
Landscape architects (no ARB requirement equivalent).
Interior designers, garden designers.

The practical answer

Even where PI isn't legally mandatory, UK professional firms and freelancers commonly need cover because:

Client contracts require it as an engagement condition.
Professional-negligence liability exists under general law regardless.
Reputation and marketability depend on holding cover.
Personal financial protection warrants it.
Business-model risk suggests it.

Frequently asked

Is PI insurance legally required in the UK?

Depends on the profession. Solicitors, architects, ICAEW and ACCA accountants in public practice, RICS-regulated surveyors, IFAs, and FCA-authorised insurance and mortgage intermediaries must hold PI under their regulators’ rules. Non-regulated professional consultants don't have a statutory requirement but typically need cover contractually.

Do I need PI as a freelance consultant?

Not legally in most cases, but practically yes. Client contracts commonly require it. Professional-negligence exposure exists regardless.

Are self-employed professionals required to have PI?

Depends on the profession. Self-employed solicitors, architects, accountants etc still need statutory cover. Self-employed consultants without a regulator: contract-driven.

Can I trade without PI insurance in the UK?

Depends on profession. Regulated professions cannot practise without statutory PI. Non-regulated professionals can trade without cover but face full personal exposure to professional-negligence claims.

What happens if I don't have PI insurance and I'm sued?

You face personal exposure. Legal costs plus any damages fall to you personally. In firm structures, personal liability depends on the entity (partnership, LLP, ltd company).

Do sole traders need PI insurance?

Same question as self-employed. Depends on profession. Regulated: yes statutorily. Non-regulated: not legally, but practically for most contractual and risk-management reasons.

Is PI insurance mandatory for CIC or charity trustees?

Trustee liability insurance is not legally mandatory but strongly recommended. Trustee personal exposure exists under trust law.

Can a client require me to have PI even if my profession doesn't?

Yes. Client contracts commonly require PI cover as an engagement condition, especially in corporate, public sector and financial services procurement.

How these figures are produced

This guide is built from Apex's own market data: the premiums insurers have actually quoted and charged on professional indemnity risks we have handled. Each night that data is aggregated into anonymised rate bands by profession, fee income and limit of indemnity. No client information is published — a band only appears where it contains at least five separate records, and unusually high premiums are excluded so a single atypical risk cannot distort the guide.

The range shown spans the typical spread of recent market outcomes for similar risks. Individual quotes can fall outside it in either direction. Figures exclude insurance premium tax at 12%.

This calculator is not a quote and is not an offer of insurance or advice. Your actual premium depends on full underwriting of your business, including your activities, claims record and insurer appetite at the time.
