Commercial experience. Sustainability understanding.
Hello, I'm Gavin Miller. I've spent more than 25 years in commercial and managing director roles, including senior positions at BBC Worldwide and Universal Pictures, and running B2B media and marketing businesses.
My background is commercial leadership and strategic marketing: what a business offers, how it's positioned, where it makes money and when it needs to change. Since 2022, I've applied that experience to sustainability, working with SMEs and larger organisations on customer and supply-chain requirements, sustainability strategy, carbon reduction, circularity and renewables business cases.
I look past the story a business tells about itself to see what's really happening, then help people decide what to do next. My approach is independent, practical and focused on what makes sense for your business.

What clients say
“Gavin combines commercial thinking with practical sustainability expertise. He focuses on what sustainability means in real business terms rather than theory or ESG reporting.
He provided clear, actionable advice and a coaching style that helped us rethink how we approached the challenges we were facing.
He also delivered a written strategy document that gave us a practical foundation and pathway for moving forward. It was a strong mix of commercial clarity, practical sustainability insight and hands-on support.”
-- Nick Payne, Managing Director SA Brain
“What really sets Gavin apart is how well he gets both the sustainability world and the commercial one. That mix meant we ended up with a strategy that wasn’t just ‘nice to have’ but something people could get behind and deliver. He brought our teams along for the ride and helped us talk to clients about it in a way that felt honest, inspiring, and practical.
He made a big difference to our journey. I’m really glad we had him on board and I wouldn’t hesitate to recommend him to anyone looking to do sustainability properly."
-- Group Managing Director, Retail Marketing & Logistics Company
"Gavin facilitated a full-day sustainability session for a room of people from the same sector but with very different commercial priorities. He managed something genuinely difficult - bridging real commercial pressures with genuine sustainability ambition, without making either feel like a compromise.
His candour, warmth and depth of experience created an environment where people felt comfortable being honest and had their thinking genuinely challenged. Lively, enjoyable and substantive - a rare combination.
If you're looking for a facilitator who can hold a complex room and leave people energised, I'd recommend Gavin without hesitation."
-- Cheryl Chung, Corporate & Government Affairs
