The Investment: Custom project fee / day rate
Who it is for: Businesses wanting to verify the true green credentials of their supply chain and commercial partners.

• The Solution: An independent, hard-nosed review of your supplier contracts, partner credentials, and value chains against global ESG benchmarks.
• The Strategic Outcome: A clear assessment of your supply-chain risk, verified partner data, and a practical framework to align your suppliers with your own commercial values.

Who it is for: Berkshire & Surrey B2B companies facing urgent commercial pressure from their own corporate clients, buyers, and boards.

Commercial experience. Sustainability understanding.
Hello, I'm Gavin Miller. I'm not a technical scientist or a checkbox ESG bureaucrat. I am a former SME media and marketing Managing Director, Commercial Director, Marketing Director (BBC Worldwide, Universal Pictures) who spent 25 years turning around businesses, driving double-digit revenue growth and margin growth in changing markets.
Today, I help Thames Valley SMEs navigate the commercial realities of sustainability. Whether you are facing soaring energy costs, struggling with complex customer supply-chain mandates, or trying to figure out if renewable energy makes financial sense, I look past the green narrative to see what's actually happening on your bottom line. My approach is independent, candid, and entirely focused on what makes practical business sense.

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
