About Us

The Datum Group is a leading national contractor based in Hertfordshire and operating nationwide.

Since its inception in June 2016, The Datum Group has developed from a small-to-medium sized main contractor into a multi-divisional construction group consisting of joinery, electrical and plumbing divisions.

This transformation has happened as a result of our business acquiring established, skilled tradesmen in these specialist areas; people we trust to deliver on quality and people who we would want working in our own homes.
