PI vs Media Liability for UK marketing agencies
Marketing agencies routinely face two distinct third-party liability exposures — client-brought claims about advice and strategy (PI territory) and content-driven third-party claims from defamation, IP infringement, or ASA rulings (Media Liability territory). Which product responds depends on the trigger, not the industry.
The two products in one line each
PI — advice and service
Covers the agency's liability to the client for negligent advice, strategy failure, campaign design deficiencies, and other ‘the agency got it wrong’ scenarios.
Media Liability — content and publication
Covers the agency's liability arising from the content it creates or distributes: defamation, IP infringement, advertising code breaches, invasion of privacy.
Claim triggers mapped
PI-only triggers
Client alleges campaign design didn't achieve business objectives. Strategy advice was deficient. Timeline missed causing lost seasonal opportunity. Positioning error causing brand damage.
Media Liability-only triggers
Ad ran with unsubstantiated performance claim — ASA upheld complaint. Creative used stock image without full licensing — IP claim. PR statement contained inaccuracy about competitor — defamation claim. Campaign identified individual by proxy — privacy claim.
Both-triggered scenarios
Campaign combining strategic failure (PI) with content-driven ASA ruling (ML). Client sues for both the strategy failure and the content damage.
Practice-model matching
Pure strategy consultancy — PI only
Brand strategy, market research, positioning. No content production. Standard PI cover.
Content and creative agency — PI + ML
Design, copywriting, video production, advertising creative. Both products essential.
Full-service digital agency — PI + ML + cyber
Strategy + creative + digital execution + data handling. All three products. Cyber often bundled where the agency handles client customer data.
PR agency — PI + ML (with defamation focus)
Reputation management, media relations. Defamation extension in ML is critical.
Performance marketing / paid media — PI + ML + cyber
Ad-buying, retargeting, personalised marketing. PECR/GDPR exposure requires cyber cover for marketing communications compliance.
Common wording concerns
- PI wordings for agencies typically exclude broadcast, publishing, and content-driven risk — that's Media Liability territory. Buying only PI leaves content exposure uncovered.
- Media Liability wordings vary widely on defamation, IP-infringement, and ASA-defence-cost coverage.
- Standalone ML products from specialist insurers can be broader than combined PI+ML packages.
- Cyber overlap matters for agencies handling client customer data for marketing purposes.
- Regulated-industry marketing (financial services, pharma, alcohol) often requires wording extensions for sector-specific advertising rules.
How the products combine
Some insurers offer a combined PI+ML package for agencies. Others require separate placements. Combined packages simplify claim handling but can have gaps at the seam. Separate placements can be broader but require careful coordination when a single event triggers both.
Agencies with substantial regulated-industry work (financial promotions, pharma advertising, alcohol) often need specialist ML wording extensions beyond standard agency packages.
