Your Fractional Commercial Director
WHERE Business Strategy Meets Sustainability.
London & South East
On‑demand and outsourced commercial and sustainability expertise for businesses and professional services companies but at a fraction of the cost of a full‑time hire.
ABOUT ME
I’m a Commercial Director with 25 years helping organisations grow, adapt and change.
A career built at BBC Worldwide and Universal Pictures, and in mid-market businesses where I led transformation and turnaround.
I now work with business owners to understand what is really holding their business back whether it is profitability, systems, or market positioning and what needs to change.
Where building a resilient, responsible business is the priority, I bring a practical sustainability lens to the commercial strategy.

The Diagnostic: 8 Questions
Courtesy of Koch & Nieuwenhuizen’s Simply Strategy I start with the questions that cut through the "story" and get to the commercial reality:
Who are we and what do we actually do?
Where do we really make money?
Is this a good industry to be in?
How strong is our competitive position?
What do our customers actually think?
How do we increase profit quickly?
What do we do that nobody else does?
What does business look like through a sustainability lens?
Many can't answer all eight cleanly. That's usually where we start.

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
-Group Managing Director, Retail Marketing & Logistics Company
