JDGray Associates is an emerging building services consultancy established in early 2011.  Our aim is to develop a practice which is sustainable in its actions toward the environment, our clients and our staff.  We strive to be marked out for quality of service and the integrity of our conduct.

The practice is directed by Jonathan Gray, a Chartered Building Services Engineer with experience in a wide variety of project sectors.  After completing a PhD in fluid mechanics, Jonathan began his building services career with Arup, before relocating and working with WYG.  He excelled in client facing project roles, and gained experience in education, large scale residential, MOD and other commercial sectors.  He remains committed to bringing innovative and sustainable design solutions to his projects.

JDGA is partnered with a number of building services consultants, technical staff and larger organisations, allowing the flexibility to form a team that best meets the needs of each individual project.  Jonathan will oversee and be directly responsible for all projects undertaken by JDGA.

Innovation and technology have been placed at the heart of the practice since its early development.  The primary design tools employed are the TAS thermal modelling software, and Revit BIM package.  We are therefore in a position to offer high end consultancy as required by your projects.
