Built On Better Service. Driven By Your Comfort.
Diamond Climate is the next chapter in our family-run heating and cooling business, providing tailored solutions for comfortable, efficient homes.
From air-source heat pumps and air conditioning to traditional and alternative heating, our focus remains simple: expert advice, honest communication and workmanship we’re proud to put our name to.
A Family Business With A Clear Purpose
Husband and wife Ian and Louise Simm started Diamond Gas & Heating in 2011 with a simple belief: the heating industry could provide better customer service, clearer communication and a more personal experience.
As the family business developed, its services grew beyond traditional heating into cooling, heat pumps and renewable technologies. Diamond Heating & Cooling became part of that journey, alongside Diamond Green Energy.
Diamond Climate carries that experience forward with a renewed focus on modern home comfort, bringing heating and cooling together under a dedicated identity.
