About Us

Company History

McColl’s is a family business founded on 19th May 1966 as Duncan Stewart Coaches in Dalmuir, Clydebank. However, after 7 years, the company became a part of the McColl’s family.  

The main depot was shortly relocated to Ballagan just outside of Balloch. A second depot was opened in Dalquhurn Industrial Estate, Renton before both were merged to a larger depot in Vale of Leven Industrial Estate which remains our current home. 

We have had some various re-branding over the years including our fleet colours/design, company name and family management team. 

The core and fundamental success of our business has always remained customer focused delivering safe, reliable and high quality services. 


McColl's operate a number of local service buses throughout Dunbartonshire & Glasgow.

Over the years, McColl's have provided transport for a range of equities such as local bus services, school contracts and the private hire sector.

From our Dumbarton base, we operate a fleet of over 30 buses on a mixture of service, school and private hire work.

We continue to invest in our people and our fleet and keeping up-to-date with the latest systems to ensure we give our customers the best we can offer.
