Jon Belfield

Managing Director​, InTandem Systems




After the completion of an apprenticeship in Machining and Fitting followed by a BSc in Engineering with Business Studies in the mid-1980’s, Jon started his career in the Building Services sector with Landis and Gyr as a Sales Engineer and progressed to a Senior Project Engineer within two years.

Over the subsequent decade Jon developed his skills/experience of controls through a variety of different challenges ranging from telephone controlled lighting systems to medical electronics, process controls and automation. After 12 years of controls experience he identified a gap in the market for a customer-led (as opposed to product-led) controls company and as a result InTandem Systems Ltd was formed. This 35+ year career has enabled Jon to experience and contribute to an extensive range of projects and initiatives in the controls sector and to invest significantly in the development of future BMS Controls Engineers. He is a past President of the BCIA and is Fellow of CIBSE and a Chartered Engineer and promotes professional development for all BMS Controls Engineers.
