Professional Indemnity Insurance for Project-Based Work

Updated April 2026

Project-based professionals face unique PI insurance challenges: variable income, discrete deliverables, and claims occurring months or years after project completion. Understanding how to structure cover for contract work ensures you stay protected between engagements.

Variable Income and Cover Adjustments

Project-based work creates income fluctuations. One quarter you're managing three concurrent contracts; the next you're between jobs. PI insurers account for this through annual turnover estimates rather than fixed premiums. You declare expected turnover; premium is calculated on this figure. If actual turnover differs significantly, mid-year adjustments apply. Overestimating inflates premiums you won't recover; underestimating can void claims if your actual exposure exceeded declared limits. Most brokers ask for three years of accounts to establish a baseline, then adjust annually based on new project pipelines.

Project Completion and Retroactive Coverage

A critical issue for project-based professionals: when does a claim arise? Under claims-made policies, the claim date matters, not the incident date. You complete a website redesign in January. In July, the client discovers the design doesn't meet accessibility standards and sues. The claim arises in July—so your July policy covers it, not your January policy. This means cover must extend beyond project completion. Extended reporting periods (tail cover) are essential when you stop working; they protect you from late-discovered defects in completed projects.

Scope Creep and Liability Expansion

Projects often grow beyond original scope. What started as a three-month consultancy becomes six months with additional deliverables. Client expectations shift mid-project. If your original scope didn't cover certain deliverables, but you provided them anyway, liability exposure increases. PI insurance covers work within your declared scope. If you're regularly taking on work outside initial contracts, your declared scope (and cover) may not match actual exposure. Brokers need transparency about typical scope changes to adjust cover accordingly.

Contract Terms and Insurance Coordination

Client contracts often impose specific liability requirements: indemnity clauses, liability caps, insurance minimums. Some contracts require you to maintain PI with minimum cover of £1 million. Your policy may only provide £500,000. This creates an uninsured gap. Other contracts demand you indemnify the client for their own negligence—uninsurable. Review contracts before accepting them and ensure PI cover aligns with contractual obligations. Many project-based professionals find themselves working under conflicting terms across different clients.

Portfolio-Based Professionals

Designers, photographers, developers, and creatives often deliver discrete work products (portfolios, campaigns, applications) rather than ongoing services. Each project is a distinct deliverable with its own liability profile. Cover needs scale with project complexity and client impact. A branding designer creating a logo carries less exposure than a software architect designing a financial platform. Some insurers offer tiered cover reflecting project risk; others use turnover as the primary metric. Ensure your cover level reflects the most complex, highest-value projects you typically undertake.

Frequently Asked Questions

How do I report variable income for project-based PI insurance?

Most insurers ask for average annual turnover from the last 3-5 years. If you've just started, provide estimated figures with supporting documentation. Changes in project volume require mid-term adjustments.

Does my project completion affect my PI cover?

Project completion doesn't end cover—claims-made policies cover claims made after the project ends, provided the project was completed during the policy period. Extended reporting is important here.

Can I get PI insurance for a single large project?

Yes, project-specific policies exist for one-off contracts. Costs are higher per pound of cover but suitable for contractors who work intermittently. Minimum premiums typically apply.

What happens if I take on less work than projected?

Most policies allow mid-year adjustments. If your turnover falls significantly, you can reduce cover and get premium refunded. Honesty matters—underreporting exposes you to claim rejection.

Is PI insurance valid during project negotiations?

Yes, cover applies from policy inception regardless of whether projects are confirmed. Quotes, bids, and advice you give during negotiation are covered as long as the work falls within scope.
