NFRC provides the secretariat for The Green Roof Organisation (GRO), which is the independent UK body representing the industry trade associations, manufacturers and key players within the green roofing sector. GRO sets out to promote the green roof concept provide suitable guidelines to both manufacturers and installers and to recognise and promote correctly trained green roofing companies.
In February 2011 GRO produced the first edition of the Green Roof Code for the UK. The code, which was the result of technical cooperation across the UK green roof industry, was intended to be recognised as the code of best practice and guide behaviour relating to green roof design, specification, installation and maintenance. In October 2014, the latest edition of the Code was published.
