Customer Testimonials

See what our clients across the UK say about F A Vaughan Ltd’s energy efficiency consultancy and EPC services.

Francis was recommended to us to provide thermal modelling to evaluate overheating. We have utilised Francis’ services on a number of occasions now, to provide both CIBSE overheating analysis in residential schemes and also hybrid ventilation to classrooms to meet EFA standards and regulations. We have found Francis to have a huge amount of knowledge and experience which has been invaluable. Francis has always worked hard and been able to meet tight deadlines as needed and is a pleasure to work with.

John Holland
“Francis has always worked hard and is a pleasure to work with”

Francis has assisted us on a range of building types for almost 20 years, providing dynamic simulation modelling, overheating and energy analyses. His vast experience has been an invaluable asset in developing practical passive solutions to environmental control, and his clear and concise reports have been extremely useful in informing architects and clients on the background behind the science.

Michael Popper
“His vast experience has been an invaluable”

F A Vaughan have worked for us on several projects ranging from stadia to residential. The services provided have varied form heat analysis to bespoke system energy and building performance. We have never been disappointed, Francis works very hard and professionally to achieve our requirements, some of which have been very impressive.

Jeff Parkes
“We have never been disappointed”

We have worked with Francis Vaughan on a number of new build schemes & found him to be most helpful, working together as an integral part of the design team. We wouldn’t hesitate employing Francis on future projects.
