About Delta T Growth

Built by
a heating
engineer.
For heating
engineers.

I started my heating apprenticeship in 2001 and spent the next 24 years in the industry: on the tools, at British Gas, training engineers at Worcester Bosch, and then working in global marketing at Bosch in Switzerland.

I've been on the van. I know what a busy day looks like when you're running a trades business. And I know what makes a homeowner pick one business over another.

Delta T Growth exists because I could see the gap clearly: the trades are underrepresented online, and the marketers trying to reach them don't understand the industry well enough to do it properly.

2026

Delta T Growth founded

Saw it clearly: the trades are underrepresented online, and the marketers trying to reach them don't get them. Built an agency that does.

"Most marketing agencies have never been on the tools. They don't know what a busy engineer's day looks like, or what makes a homeowner pick up the phone. I do. That's the whole point of this business."
