You might know us for air tightness testing, acoustic assessments and making compliance straightforward. But behind APT UK is a person, and that person has a story worth sharing.
Our founder, David Ian Charnock, has spent more than 35 years building a business rooted in precision, experience and genuinely caring about the people he works with. What you might not know is that alongside that journey, David has been on another one entirely — a deeply personal quest to understand what it really means to live and work well.
That journey has led to a book.

None the Wiser – How to Create Real Magic in Your Life and Manifest Your Best 24/7
David’s own words describe it best. His quest began with a moment of stark, uncomfortable honesty — waking up to the realisation that despite everything he had built and everything he had worked for, he was, in his own words, simply none the wiser about life.
It’s a feeling many of us will recognise, even if we rarely say it out loud. The sense that we’re moving fast, ticking boxes, getting through — but not truly understanding the deeper mechanics of why some people thrive, find contentment and build genuine prosperity, while others stay stuck in the same patterns regardless of how hard they work.
Rather than sitting with that frustration, David did what he’s always done. He got to work.
What followed was years of exploration, study and real-world application — working with clients and businesses across the world, testing ideas, refining approaches and building what he describes as a universal toolbox of real magic. Not the abstract, vague kind. The practical, usable kind that creates measurable change in people’s lives and in the businesses they run.
Why It Matters
This isn’t a book of empty motivation or recycled self-help platitudes. It’s the honest account of a man who built a successful business, felt the gap between outward achievement and inner fulfilment, and refused to pretend it wasn’t there.
Inside, David shares the insights, guidelines and approaches that have helped countless individuals and businesses increase profitability, find clearer purpose and experience more genuinely fulfilled lives. It’s for the entrepreneur who feels like something is missing. For the professional who is successful on paper but knows there’s another level. For anyone who has ever felt like they’re doing everything right and still not getting where they want to be.
If that sounds familiar, this book was written for you.
