GSCOP Training

Leading GSCOP Expert & Trainer in the UK

As the leading GSCOP expert and trainer in the UK, I have helped more grocery suppliers across Europe than anyone. I specialize in helping suppliers navigate the UK grocery retail landscape with confidence through comprehensive training, advisory, and ongoing support.

What I Deliver:

  • Practical GSCOP training for board members, senior teams, national accounts, and sales teams
  • Real-world scenarios and case studies
  • Guidance on rights, obligations, and retailer relationships
  • Ongoing advisory support for complex situations
  • Training on Competition Law and Bribery Act for supplier teams

Impact:

Thousands of suppliers trained across UK and Europe. Suppliers who follow GSCOP guidance have overturned delistings and grown multi-million pound contracts. Recognized authority aligned with GCA best practice.

"Really appreciate you coming in yesterday. The team really enjoyed the session and took a lot of learnings from it."
