SC Duncan was formed in 1973, and was rebranded in 2019 to modernise its look with our discerning customer base. We have set out to be a local service provider with the values and service you would expect from a local company, but with the modern service and delivery of a National brand. SC Duncan Heating, Plumbing and Electrical was initially formed to service all the mechanical needs of our customers in Hertfordshire and then in 2020 we started SC Duncan Construction due to demand from our existing customers.
