Our Story
Evolved Energy Services was founded with one simple aim: to bring smarter, more efficient heating, cooling and plumbing solutions to homes and businesses across Fife and East Scotland.
Iain Johnston started the company after more than two decades working in the trade. He saw a growing need for honest, high-quality workmanship combined with modern, energy-efficient systems – and decided to build a business that did exactly that.
From the start, Evolved Energy has focused on combining traditional trade values with cutting-edge heating technology. We’re proud to be one of the few Heat Geek Elite installers in Scotland, and even prouder of the trust we’ve earned from homeowners and commercial clients alike.
We work across residential and commercial sectors, offering everything from plumbing and boiler installations to bespoke heating design and air conditioning.
The industry’s always evolving – and so are we.
