Commercial & Sustainability Advisory, Coaching & Training for SMEs

Make Sustainability Work for Your Business.

A conference room filled with attendees listening to a panel discussion. The large screen displays a presentation titled 'What does sustainability mean for my business?' featuring photos and names of three speakers: Amy Goodman from TeamPeople, Gavin Miller from gavinnmiller.co, and Neil Clark from MSQ. People are seated at tables with water bottles and note-taking materials.

Sustainability is becoming a requirement for doing business.

If you sell into larger businesses or operate in competitive supply chains, customer expectations are shifting fast.

Procurement teams want evidence. Tender processes require credentials. Customers are issuing detailed questionnaires on emissions, policies and responsible business practices.

Most SME leaders don't have the in-house capability or dedicated resource to navigate this and they don't want theoretical consultant reports that ignore commercial reality.

I work alongside business leaders and teams on a fractional, advisory and coaching basis to help you:

  • Understand exactly what customers and supply chains are asking for

  • Cut through the noise and establish where your business actually stands

  • Build the internal capability, confidence, and commercial strategy to respond effectively

  • Embed practical, responsible practices that protect margins and strengthen relationships

Who is this for

Build the understanding and confidence to navigate sustainability and responsible business and apply it in your role.

Some Recent 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

“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

"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

"Gavin is consistently helpful, knowledgeable, and a pleasure to work with. He's helped us to get started with clarity about sustainability and what this means in practice, well beyond carbon footprints. Thought-partnership in these early stages has been invaluable."

-Saskie Dorman, NHS Palliative Care Consultant, Forest Holme NHS Hospice

"We had a brilliant workshop with Gavin – lots of fantastic insights and a whole new perspective on sustainability and marketing in a sustainable world."

-German National Tourist Board

“We would like to thank Gavin Miller for his time with the Climate Partnership Steering Group. He has had a brilliant and useful impact on business interactions and the Climate Strategy.”

-RBWM Climate Partnership Committee Chair

“I've worked with Gavin for the past two and a half years and have found him to be a truly inspirational leader. His expertise in running businesses (and turning them around!) is second to none. I have learned more from him about business strategy, commercial awareness and people management in the past two years than I have during my entire 17-year career in publishing.
