Business Gateway support fuels rapid growth for Dunndee Gas
A Dundee-based gas supply business that launched from one entrepreneur’s determination to protect local customer relationships and continue a trusted service is now celebrating a six-figure turnover with plans to expand further.
Dunndee Gas, founded by owner and director William Dunn, was established after he identified an opportunity to continue serving customers across Dundee and the surrounding areas following the closure of his previous employer.
William first approached Business Gateway to assess the viability of starting the business. Having previously worked for another gas supplier in Dundee, he had already built strong relationships with residential and commercial customers, as well as supplier contacts, through years of hands-on experience in deliveries, operations and office management.
William said: “I started in 2018 as a part-time driver for another gas company, delivering to residents and businesses in Dundee and the surrounding areas. Over time, I moved into a full-time role, gained my ADR licence and took on larger loads.
“I got to know all the customers personally and built strong relationships with them, as well as with staff at Calor and BOC. As the previous business moved towards closure, conversations began with Calor about the possibility of me becoming a distributor myself.
“What started as a discussion to help soon became the beginning of Dunndee Gas.”
With support from Business Gateway’s Early Stage Growth (New Business Plus) service, William received tailored advice across key areas including business planning, VAT registration, HR and digital support.
This support helped lay the foundations for Dunndee Gas to secure a 2.78-acre site, from which the business now supplies Calor cylinders for a wide range of domestic and commercial needs. The premises also includes convenient on-site customer parking, making cylinder collection simple and accessible.
Since launching, the business has grown to employ four members of staff, including an experienced driver who previously worked alongside William, ensuring customers continue to receive the same reliable and friendly service.

Today, Dunndee Gas has reached six-figure turnover and is on track to achieve its ambitions William set out when he first began working with Business Gateway.
William added: “The support from Business Gateway has been invaluable in helping turn my idea into a sustainable and growing business. From planning and registration through to HR and digital advice, it has given me the confidence and structure to grow the right way.
“Our main priority is to provide excellent customer service and we’re focused on building our marketing activity and growing further, with plans to bring in more drivers as demand continues to increase.”
William is currently continuing to work with Business Gateway’s digital support team to strengthen the company’s marketing plans and support the next stage of growth.
Business Gateway adviser, Stuart Milne, said: “William’s journey is a fantastic example of how sector experience, strong customer relationships and the right support can come together to create a thriving local business. Dunndee Gas has built impressive momentum in a short space of time, and we’re delighted to continue supporting its future growth plans.”
