Your Fractional Commercial Director
Sustainability built in.
Companies don’t always need a full-time Commercial Director.
That’s why I provide experienced commercial leadership on a fractional basis, helping B2B businesses improve performance, grow, reposition or respond to sustainability demands, but without the cost of a full-time hire.
Business first. Sustainability built in.
I start with the business: what you sell, who you sell to, where you make money, what to stop, what to start, how you grow, what gets in the way and where the risks are.
And I don’t just talk about sustainability. I’ve worked inside businesses to develop sustainability strategies, respond to customer and tender requirements, strengthen ESG credibility, assess risks, build capability and turn plans into practical action.
I can provide that support as:
Fractional Commercial Director
Ongoing part-time leadership to help you grow, reposition and improve performance, while building the skills and capability to manage sustainability as part of the business.
Focused Commercial Projects
Practical support for customer sustainability demands, climate and sustainability risks, or transition planning.
Workshops & Capability Building
Helping teams understand the issues, align priorities and agree what to do next.

SOME CLIENT TESTIMONIALS
“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.” May 2026
-Nick Payne, Managing Director SA Brain
"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
“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." November 2024
