The latest news, articles and insights from Terry
Over the past few years, I’ve been deeply involved in a business that I believe has the potential to change the way we think about energy efficiency—OH4.
What started as a bold idea has now grown into a thriving, results-driven venture. After more than three years of development, testing, and refinement, we're finally seeing the kind of results that validate our early belief in this project—and it’s incredibly exciting.
We’ve recently completed successful trial installations at several well-known commercial sites, including Spire Hospitals, Greene King pubs, and Decathlon. These weren’t just pilot projects—they were proof points. Each trial led to further site installations, thanks to measurable improvements in energy efficiency and cost savings.
Building on this momentum, we’ve now turned our focus to residential properties, where we’re running strenuous testing to validate performance at the household level. Proving the concept in private homes will open the door to an even larger market—one that’s ready and eager for smart energy solutions.
Once this phase is complete, we’re anticipating a fast and scalable rollout.
This journey hasn’t been quick or easy. It’s taken time, patience, and a lot of technical problem-solving to get here. But the results we’re now seeing make it all worthwhile.
In fact, I genuinely believe OH4 could turn out to be my best investment to date—not just financially, but in terms of impact, innovation, and long-term sustainability.
Watch this space. The energy-saving revolution is just getting started.
