Forty-four agencies have earned IPA Effectiveness Accreditation for demonstrating their commitment to business effectiveness and delivering commercial outcomes for clients, setting the industry benchmark.
This marks the highest number of accredited agencies since the biennial programme’s inception in 2021, with 19 agencies awarded IPA Effectiveness Accreditation for 2021-23, and 30 agencies for 2023-25.

Commenting on the IPA Effectiveness Accreditation 2025-27:
Alessandra Bellini, Chair of Judges for the IPA Effectiveness Accreditation, says:
“Huge congratulations to all the agencies that have earned their IPA Effectiveness Accreditation for 2025. It is a remarkable and incredibly important achievement for agencies. The Accreditation gives you the opportunity to assess where you are as a business and allows you to benchmark yourself against competitors. Most importantly, though, earning IPA Effectiveness Accreditation clearly demonstrates that effectiveness and delivering commercial outcomes, underpinned by great creativity for clients, is embedded into everything you do.”
Sadira Furlow, Chief of Global Brand & Communication, Tony’s Chocolonely and IPA Effectiveness Accreditation Judge, says:
“As a client, it is important to focus on effectiveness because we are always looking for work that is going to drive business results. Agencies that are IPA Effectiveness Accredited really stand out from the rest, because they have demonstrated that they are rigorously embedding effectiveness throughout their entire process.”
Laurence Green, Director of Effectiveness at IPA, says:
“The IPA Effectiveness Accreditation scheme is a wonderful complement to Karen Martin’s creative agenda as IPA President, because – properly practised – a culture of effectiveness provides the scaffolding for more imaginative solutions, not less. I’m therefore delighted to see so many agencies earn IPA Effectiveness Accreditation this year, as it highlights how the conversation around marketing effectiveness continues to thrive and evolve year after year.”
