    Lewis has been an amazing source of advice and support for us at It takes a City - challenging how we think and taking us on a journey to improve our efficiency as a business as we take on an exciting new project. Lewis’ support of charities is an incredible example of businesses supporting the charity sector. Excited to continue working with you!

    I've used Lewis & Underpin Consultants as speakers at my networking events. Their marketing sessions are always very well received (that's why I've used them more than once!) and attendees leave with a lot information and suggestions for their businesses. Lewis is a great networker as well and definitely worth taking the time and effort to know.

  • We all need someone who can take an idea, truly listen, and turn it into something even better than we imagined - and that’s exactly what Lewis did for us. It was a real pleasure working with him on refining the new logo for our network. We wanted a members' logo that our community could use with pride, and thanks to Lewis’s creative insight and thoughtful recommendations, we now have a design that we’re genuinely proud to share. Thank you, Lewis, for helping us create something that not only looks great but also truly reflects who we are and what we stand for. I’d wholeheartedly recommend Lewis for any marketing or design work - especially if you're after something purposeful, polished, and perfectly aligned with your brand.

    Lewis has provided invaluable advice on funding and strategy for ootiboo CIC. From the outset, his deep knowledge of the funding landscape was clear. His straight-talking, common-sense approach has helped us sharpen our focus and identify the right next steps to move our company forward. I would highly recommend Lewis to any organisation seeking to build a strong, sustainable future. We look forward to continue our journey with Lewis in our quest to bring real-life skills to the next generation.

    Lewis held a consultation meeting with myself, with no charge, and provided me with some valuable insight. His passion for helping solve your problems is clear, even with speaking for a short amount of time. I would recommend speaking with Lewis.

  • After just one business analysis session with Lewis, it was immediately clear how professional and insightful he is. Unlike many business coaches or consultants, Lewis brings a truly holistic, bottom-up approach that goes far beyond surface-level advice. He takes the time to understand the people, systems, and values behind the organisation, which enables him to create strategies that not only work — but last. I can highly recommend working with Lewis as his input doesn’t just create quick wins; it lays the groundwork for meaningful, long-term transformation that continues to benefit the business / charity long after he’s gone.

    Kris Avatar Kris

    Working with Lewis is a real pleasure. Things get done fast in a friendly and professional way. I would recommend Lewis for the quality of work and care he shows to his clients.

    I just can't rate Lewis highly enough! His work with my team for our local Charity has been incredible and empowering. If you are looking for someone to make marketing and communications easy to understand and execute underpin is for you.
