The equestrian world is changing. SEI is here to lead that change, and to support those committed to doing things responsibly.

SEI is an independent European certification framework created to demonstrate what responsible equestrianism looks like in practice, bringing together horse wellbeing, environmental responsibility, people and economic resilience within one credible Standard.

From stables, training and breeding to equine-assisted services, leisure activities, polo, racing, competitions, events and virtually any organised activity involving horses, SEI provides a framework for demonstrating responsible equestrian practice.

SEI gives equestrians something increasingly important: independently verified evidence behind what they say and what they do.

Because responsible practice and responsible claims should be demonstrated with facts and evidence — not just words.

And SEI is open to everyone — including you, as a rider, with or without your own horse. Every equestrian can be part of responsible change.

Measured. Verified. Demonstrated.

SEI — Responsibility. Evidence. Integrity.

We are one family. We are equestrians! We are SEI.
