GENSOURCE, a Musselburgh-based sustainable energy specialist, has announced it has expanded into larger premises in response to growing demand for its services.
Measuring over 1,200 sq. ft., the new base in Newhailes Business Centre is more than double the size of the company’s original home in the East Lothian town.
The move follows three years of growth for the business, which provides turnkey sustainable energy solutions covering everything from consultancy and design to construction, operation, and maintenance.
The firm said the new head office positions the company, which won High Growth Business of the Year at the 2025 Midlothian and East Lothian Business Awards, for future expansion as it looks to build on the foundations built by co-founders Josh King and Robert Wilson since setting up in December 2022.
Staffing levels now sit around the 20 mark, with plans to increase this further in the coming 12 months.
“The move is an exciting development for us and affords us more space and room to grow further,” said Mr Wilson, Gensource commercial and operations director. “It reflects how we have evolved since starting out and demonstrates our maturity as a business. We have set ambitious targets since starting out and have successfully delivered against them. Our bigger headquarters gives us the flexibility to keep expanding and continue that trend.”
Clients include the Eastern Western Motor Group, the City of Edinburgh Council, and the National Manufacturing Institute of Scotland (NMIS).
“The nature of the commercial contracts we are winning is very encouraging and is a big endorsement of the work everyone at Gensource is doing,” added Mr Wilson. “We are genuinely excited about the future. We are proud of our ability to stay on the cutting edge of technology and thanks to our new expanded headquarters, we look forward to growing with confidence in the years to come.
“The challenge of rising energy costs combined with trying to reduce carbon is very real for businesses and motivates us to keep focused on our mission to help clients meet their sustainability objectives.”
