Our History


The Modular Heating Group is founded by Michael Mainstone and John Bradley. Initially operating from a 2,000 sq ft premises in Basildon, Essex, MHS quickly built a reputation for innovation in commercial heating systems, as well as manufacturing chimney systems and assembling cast iron radiators.
