⚡ Editor's Verdict — PI + PLI Essential for All Contractors
Contractors need professional indemnity insurance and public liability as a minimum — most contracts require both. IT contractors typically need £1m PI cover; construction contractors need £5m+ PLI. Kingsbridge, Hiscox, and Simply Business are the leading UK providers.

Contractor insurance covers independent contractors and freelancers against the specific risks of contract work — professional errors, public liability, and IR35 compliance. The right cover depends on your industry: IT and professional contractors need professional indemnity; construction contractors need higher public liability limits.
