What Do IT Contractors Need?
IT contractors - whether working as software developers, data analysts, project managers, cybersecurity consultants, or other technology roles - typically need a package of three insurance covers: professional indemnity (PI), public liability (PL), and employers liability (EL). Of these, PI is the most important and most commonly required by contracts.
PI covers claims from clients for financial loss arising from errors or failures in the IT services provided. A software bug that causes a client system failure, incorrect technical advice that leads to a failed implementation, data loss during a migration project, or a security vulnerability introduced through poor coding are all scenarios that could give rise to PI claims against an IT contractor.

Frequently Asked Questions
Do I need PI insurance as an IT contractor working through an umbrella company?
Many umbrella companies require contractors to hold their own PI insurance as a condition of working through them, particularly where the contractor is the one providing the technical service to the end client. Check the umbrella company terms. Even where the umbrella does not require it, the end client or agency contract may require the contractor personally to hold PI.
What PI limit do I need as an IT contractor?
The minimum PI limit required depends on your client contracts. Most IT agency and direct client agreements require between GBP 250,000 and GBP 1 million. For financial services clients, public sector, or large enterprise clients, GBP 1 million to GBP 2 million may be required. Choosing a limit higher than the contract minimum provides additional protection for claims that exceed the client-specified minimum.
Does IT contractor PI cover data breaches?
Standard IT contractor PI covers civil liability for data loss or breaches that are attributable to the contractor negligent actions in the course of providing IT services. Many IT contractor PI policies also include a cyber liability extension covering the contractor own costs in the event of a cyber incident. First-party cyber costs (incident response, system restoration) typically require a separate dedicated cyber policy.
Is there a difference between IT contractor PI and general consultant PI?
IT contractor PI policies are specifically underwritten for technology professionals and typically include technology-specific coverage extensions and activity descriptions covering software development, systems implementation, data management, cybersecurity, and similar IT activities. A generic consultant PI policy may have activity descriptions that do not clearly cover all IT activities. Specialist IT contractor insurers understand the specific risk profile better and are preferable for technology professionals.
Does IR35 affect my insurance requirements?
IR35 (off-payroll working rules) determines whether your working arrangement is treated as employment or self-employment for tax purposes. It does not change your fundamental need for professional insurance. Whether you are inside or outside IR35, if you are providing professional IT services to clients, PI insurance is appropriate and typically contractually required. Some inside-IR35 contractors operating through umbrella companies may have PI provided by the umbrella - confirm this with the umbrella before assuming you are covered.
