Meet The Team

James D McLellan, Managing Director
James McLellan
I qualified as a plumbing and Heating Engineer in 1992 and decided to further my education in gas safety and legislation, after working as a domestic service engineer I then advanced to a foreman where I was responsible for 30 staff on larger installations working on a subcontract basis for various companies such as Bovis, Aston Cord and Apollo Services .

I furthered my education and studied for my HNC in mechanical engineering and diploma in HE and Business and joined one of Europe’s largest manufacturers of renewable energy products where I was responsible for the recruiting and management of installation partners and distributors of Renewable products and project management of large scale projects.

In 2004 I decided to take some time out and travel the world looking at all aspects of energy production and consumption which led me to Trek Through South America, South East Asia and the Southern hemisphere before returning to start up Heatsource Consultants.

Brian Baldwin, Commercial Manager
Brian Baldwin
I spent the last 20 years of my career with Vodafone Group PLC, where I held several Senior Director positions including Corporate Sales Director, UK; Marketing Director, Vodafone Group International and Global Accounts Director, Vodafone Group Services.

My background was originally in sales with Companies such as Xerox and Canon, but I graduated into broader commercial roles within Vodafone. I sat on the Board’s of several Vodafone National Companies and was heavily involved in the re-organisation of Vodafone Global resulting from the acquisitions of AirTouch in the USA, and Mannesmann in Germany. 

I have considerable experience in Start up situations, and also took leading roles in acquisitions and licence bids across the world.  Much of my time from the late ‘90s until my taking early retirement was spent performing internal consultancy on subjects like Best Practice and Delivering Global Synergies and solutions.
