What Is Professional Indemnity Insurance?

Updated April 2026

What exactly is PI insurance?

Professional indemnity insurance is a liability policy that covers the cost of claims made against you if a client suffers financial loss because of your professional negligence, errors, or failure to perform your duties. Think of it as financial protection if your work causes someone else to lose money. The insurer pays legal defence costs, court awards, and settlements on your behalf--up to your policy limit. It's essential for anyone offering professional services, from accountants to architects to IT consultants.

How does PI insurance actually work?

When a client claims you've caused them financial harm through your professional work, they make a formal claim to your insurer. Your insurer investigates, handles legal defence, and negotiates or settles the claim. You're protected from paying out of pocket and from legal costs that can easily reach GBP50,000+ for a single claim. The policy typically covers damages, legal fees, court costs, and investigation expenses. Most policies operate on a 'claims-made' basis, meaning they cover claims made during the policy period, regardless of when the work was done.

Who actually needs PI insurance?

Any professional who gives advice, creates work, or delivers services that clients rely on is at risk. This includes accountants, solicitors, architects, surveyors, engineers, IT consultants, management consultants, HR professionals, and many others. Some professions--solicitors, for example--are legally required to have it. Even freelancers and sole traders need PI insurance if they could be held responsible for financial loss caused by their professional work. If someone could sue you for negligence, you need this cover.
