Now in its third year, event:decision and micebook are once again teaming up to bring you the Power 30. For 2026-7 and onwards, the Responsible Agency Index Agencies UK becomes the Power 30 Responsible Agency Index. Nothing else changes, the recognition scheme still produces  an annual list of the definitive Power 30 – only the title more accurately reflects all elements in scope.

Open for entries 2026-7!

The Power 30 Responsible Agency Index, now in its third year, evaluates event agencies based on responsible internal business practices and the ability to deliver responsible & sustainable outcomes for clients. Unlike many industry recognition programs, this initiative is scored according to specific criteria rather than being subjectively judged. The results are qualified, scored, and benchmarked to produce a list of the best performers in responsible business & service, showcasing real capabilities and proof points for responsible agencies.

See the agencies recognised in 2025-6 here.

Thank you to our supporters:

As responsible business practice and event delivery becomes a growing priority for clients, agencies that leverage industry data are able to progress and position themselves as leaders in environmental, social and governance responsibility.

Recognition in the Power 30 enables agencies to showcase their commitment to these practices and attract clients who value stewardship and ethical delivery. More broadly, the campaign helps raise the standard across the industry. Power 30 encourages continuous improvement, collaboration, and knowledge-sharing, equipping agencies to navigate the complexities of a responsible supply chain while adapting to the evolving demands of the events sector.

Let’s continue this journey together…

Congratulations to the recognised agencies this year and those recognised in the 2024-25 Power 30. For those striving to be included in next year’s edition, the campaign serves as both a benchmark and a motivation to continue advancing responsible practices. The journey toward a better events industry is ongoing – and every step forward counts.
