ISBA Annual Legal Review 2026

In this session, we will review the most significant legal and regulatory developments affecting UK advertisers during 2026, assess their practical implications for marketing teams, and look ahead to the priorities and pressures likely to shape 2027.

What we’ll cover

• Green claims under the spotlight: New ASA guidance for advertisers, alongside the implications of the EU Empowering Consumers for the Green Transition Directive.
• One year on from the Less Healthy Food rules: The lessons advertisers should take from the first year of implementation.
• Sectors facing greater scrutiny: Including the regulatory questions surrounding weight-loss drugs.
• The CMA in 2026: A new era of consumer enforcement, significant fines and further change ahead.

Who is it aimed at?

Anyone working in in-house legal, compliance, regulatory affairs, marketing, media, digital, CRM or procurement roles at advertiser brands.

What will members gain by attending?

• How green claims may need to change to withstand future regulatory scrutiny.
• The CMA’s key areas of concern under the Digital Markets, Competition and Consumers Act, including the impact of new subscription rules expected in January 2027.
