Professional Indemnity Insurance is on a ‘claims made’ basis. This means that the policy will only respond to events which become apparent, or ought to have become apparent, during the period of insurance cover and that you have notified the insurer within that insurance period.
For example: if today you become aware of an actual or potential claim on a project you did 5 years ago, it is the policy in place today that will respond to your notification lodged today. If you delay the notification until a later insurance period, the PI cover may be in doubt.
Statutory Liability, Employers Liability, Directors & Officers, Cyber Liability and Employment Disputes insurance are all ‘claims made’ policies.
