The Green Roof Consultancy (GRC), grew out of work undertaken by Livingroofs.org and The Ecology Consultancy Limited, whilst working on the London Living Roofs and Walls technical report for the Greater London Authority. Two of its directors, Gary Grant and Dusty Gedge are recognised leaders in the field of green roofs, walls and ecosystem services. The team develops green roof systems to meet complex sustainability and ecological considerations. They have designed a number of seminal green roofs and walls and regularly provide full green roof, green wall and ecosystem services training in the UK.

Green roof technology is also widespread and well-established in mainland Europe with growing interest in the UK. Green roofs are set to become a popular technology within the UK refurbishment and development industries. However currently there is limited knowledge and understanding of this technology beyond the main suppliers. The Green Roof Consultancy was the first specialist consultancy to provide this in the UK.
