About Stroma

Stroma was formed in 2002 and initially provided air testing and acoustic testing services to the construction industry. This evolved into the Stroma Tech division and by 2007 the Group had expanded to offer approved certification and training services through Stroma Certification. In 2014, Stroma Software was formed to offer desktop and mobile software to our core industry and beyond. Then in 2015 Stroma acquired CIC Approved Inspector, Greendoor Building Control, before Approved Design Consultancy and BBS Building Control also joined the Group in 2016. Through our sister companies the Group can now provide Approved Inspector and Building Control services.
